On April 10th, while traveling approximately 7 hours from home on a very busy highway in [XXX] , my 2023 Chevrolet Tahoe (6.2L engine) suffered a complete and catastrophic engine failure, requiring a full engine replacement. The vehicle had to be towed and I was left stranded with no transportation. Prior to this failure, I had brought the vehicle to an authorized GM dealership for a recall inspection specifically related to the 6.2L engine on September 9, 2025 with 36,162 miles. The dealership technician inspected the vehicle and informed me that my engine was not defective and cleared it. Shortly after that inspection, the engine suffered a total failure at 46,6xx miles on the vehicle. I am currently leasing this vehicle at approximately $1,100 per month and have been without the vehicle for an extended period while it sits awaiting repair. GM customer care has been contracted and has indicated they cannot move forward with a buyback claim because the BBB is not taking my case because the vehicle is older then 2 years old which I know is a false legal claim. This is a serious safety concern, a catastrophic engine failure at highway speed poses significant risk to vehicle occupants and others on the road which appears consistent with other reported failures. I am aware that NHTSA has opened Recall Query RQ26001 investigating the adequacy of GM's remedy under recall 25V-274. My experience is consistent with the 36+ complaints that triggered this investigation, engine failure occurring after an authorized dealer performed the recall inspection and cleared the vehicle. I am requesting this complaint be added to the RQ26001 investigation file. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

As I was driving down the tollway in Dallas going 75 miles an hour, my engine completely shut down and went into neutral in rush hour traffic. I had to slowly get over from being in the left lane as my car was slowing and slowing. I was able to get over on the side of the tollway as cars zoomed past me. By the grace of God, I didn't get hit. Once it was towed, the service department confirmed that it is my engine that shut down and the entire engine needs to be replaced. Now the problem is they cannot find an engine or parts to fix it. No warning came on at all before this happened. Very dangerous situation.

NHTSA #11732835

Passed a truck in 2023 Chevy Tahoe on a two lane highway and the Tahoe would not accelerate. It switched into neutral and would not run. This was a major safety issue. There was a semi truck behind me that could have run over me and my family. Luckily there was wide open area next to the road that I coast into. Truck was towed to a dealership out of state while we were on vacation.

NHTSA #11729312

My wife just picked up our 4 year old from daycare. She just merged onto I-81N and the vehicle shut off on her at highway speed during rush hour! A message on the dashboard said "Please restart vehicle". She managed to pull the Tahoe off onto the shoulder, but couldn't get it started. She remained in the vehicle with my daughter and called 911 to request a state police vehicle park behind her so that she wouldn't be hit by any passing traffic. I (her husband) met her on the side of the highway and we tried starting it with a battery booster pack to no avail. We called a tow truck and had the car towed to the dealership that we purchased the vehicle from. They confirmed that the motor was indeed locked up and needs to be replaced. This vehicle already underwent the 6.2L recall test and "PASSED". It was running the 'remedy' 0W-40 oil. This is COMPLETELY UNACCEPTABLE.

NHTSA #11729123

We were driving down the highway at around 77 miles per hour. I noticed that the vehicle chimed as though I initially got into it and needed to start the engine. I saw the dashboard asking me to start the engine. I attempted to start it while we were coasting to a stop, but it wouldn't start. I was able to barely get out of the lane of travel and avoid a collision. I tried to turn off the vehicle and turn it back on but it would not start. It would not even turn over. The vehicle eventually cannibalized the battery because it would never shut off.

NHTSA #11729833

1) The engine failed and lost propulsion while driving. It is currently at the dealership where I purchased the vehicle new, so it may be available for inspection upon request. 2) My safety was put at risk because the vehicle lost propulsion while driving. This is a dangerous situation in general. In my case I was able to pull over safely and have it towed to the dealership. 3) The problem is that the engine failed. This can be confirmed by the dealership. 4) This 6.2L engine was part of the N252494001 recall for specifically the issue of engine failure and loss of propulsion, so it had been inspected by the dealership recently. I brought the vehicle into the dealership for this recall several months ago. Per the recall, they told me that the engine would need to be replaced if it didn't pass the inspection. They performed a Pico test, informed me that it passed the test, and changed the oil to 0W-40. It has not been inspected by GM, the police, insurance representatives or others at this time. 5) There were no warning lamps, messages or other symptoms of the problem prior to the failure.

Our vehicle passed their inspection required test for the engine recall and then at an intersection just died with absolutely no warning and wouldn’t even start again. Warning light for low engine oil came on. We were stuck and couldn’t even put the vehicle in neutral to be towed out of the intersection. Had to call a flat bed tow truck to load it and take to dealership where it was confirmed the engine failed!!! Police did show up at the scene to facilitate traffic and the loading of th vehicle

I purchased a 2023 Chevrolet Tahoe on December 17, 2025. On January 17, 2026, with approximately 17,000 miles, the vehicle experienced a catastrophic engine failure while I was driving. The engine seized without warning, causing a complete loss of power and leaving me stranded on the side of the road. At the time of the incident, my newborn child was in the vehicle, creating a serious safety risk. The vehicle had no prior warning lights or indicators before the failure. After the incident, I learned that there was a known recall or service update related to engine oil viscosity for this model year. This information was never disclosed to me at the time of purchase, and no recall documentation or corrective service was provided prior to delivery. I have since been informed that engine replacement will take over 30 days due to parts availability and that no loaner or rental vehicle is available during repairs. Given the catastrophic failure shortly after purchase, the undisclosed recall, extended repair time, and safety implications, I no longer feel the vehicle is safe or reliable.

On December 30, 2025, I was driving the Tahoe at a highway speed in Oklahoma City, Oklahoma. I experienced two engine shut-offs. I was able to get the Tahoe to the Chevrolet dealer in Midwest City, OK. Advisor Tim took care of the vehicle and said that they "couldn't replicate the problem." He did mention he had to add engine oil because it was a quart low. We noted that we are currently conducting an oil consumption test with a Chevrolet dealer in Elk Grove, Illinois. He said we had a strong case for it, but the Tahoe was safe for traveling back home to Illinois. The following days, the Tahoe performed well without any issues. On January 3, 2026, we left Spencer, OK, and headed back home to Illinois. Without any warning, while driving at highway speed, the engine shut off completely and would not restart. The failure occurred at approximately 9:00 pm on a pitch-black expressway about 40 miles from Rolla, Missouri. I was traveling with my wife and two children. We were stranded on the highway shoulder. A state trooper was dispatched for safety. The Tahoe required a tow over an hour later, and we had to take a Lyft to a hotel. Logistics at that time in that location were complicated. Our family was terrified for our safety. Today is Sunday, and the nearest dealer is closed. We will have it dropped off tomorrow, January 5th, and go from there. We do not know how we are going to get back to Illinois. We have work and my son has school. The vehicle is currently disabled and under manufacturer warranty. This was a serious safety incident involving loss of engine power at high speed.

I bought this 2023 Chevy Tahoe rst brand new from the dealer and about a few months of owning it I noticed that the truck was needing oil before the next oil change. It’s as if it was consuming itself. This continues for month until last week when the truck died on me. I was able to jump start and everything worked fine for a day. The next day things got worse. I was on the highway and truck started shaking and giving off all kinds of codes. I took it to dealer and they said I needed a new battery but that there was also an engine problem. I bought a new battery and none of the messages on dash resolved like I was told. The truck is u drivable motor is knocking and was even making loud popping sounds. Of course my truck just hit 64,000 miles so gm is saying I’m out of warranty. I should not be having these types of issues on an almost brand new truck that I’ve owned 2 years. Engine light is flashing and dealer said this means major issue.

on [XXX] we bought our 2023 Tahoe High Country from Jeff Gordon Cheverolet in Wilmington NC. In April 2025 a recall was announced on our car for engine failure. In June of 2025 we received a letter stating that a fix for the recall was to have an inspection done. If passed, then an oil change and new cap would be done. This was completed. on [XXX], I was on the highway accelerating to get up the speed, when I heard a loud pop noise. Then i heard loud knocking coming from my engine, the check engine light came on with the traction light as well. The car then had sluggish acceleration and would not accelerate but would have high than normal RPMS and rev when trying to accelerate. I knew then that I had engine failure. I was able to get the car to a safe place and called the dealership right away. They got it towed to Marine Chevy since it was closer. The next day they did an inspection on the vehicle and said the camshaft and lifters were broken and had to be replaced. I said I would need a new engine replaced due to the damage and recall. I was told it would not be under recall because it was the top and not bottom. They said the GM refused the new engine but would not tell me if it was the General Manager or General Motors that refused. I called and texted multiple times asking for pictures. They refused to send me any until 9/9 after multiple attempts. They only sent me one of the rods and rocker arms showing a rod bent and stated it was the lifters. still no pictures of the camshaft broke or lifters. These problems already have multiple class action lawsuits out for this particular engine failure. I was told the recall would still be on the engine even after the repair, I can still have engine failure. I refuse to pay the money for this car to continue to be in the shop due to a bad engine that was put in these models. I also have a case open with General Motors for replacing the engine as well and they are refusing to help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When i asked Kunez Lake Geneva, Wi. When the engine recall would be taken care of. I was told that GMC has to order the recall first. Then when asking about the process of inspecting. They informed me they would listen to the motor and decide if it was effected or not. I paid $82k for this vehicle. I find that listening to the motor isnt a thorough way of inspection. After they deem the motor ok. There going to put higher viscosity oil & an oil cap. What if something happens in the future. Is my familys life safety not important? Summary General Motors has decided that a defect which relates to motor vehicle safety may exist in certain 2021 – 2024 model year Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL vehicles equipped with the 6.2L V8 gas engine (RPO L87). The connecting rod and/or crankshaft engine components in these vehicles may have manufacturing defects that can lead to engine damage and engine failure. Safety Risk If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. Remedy Dealers will inspect and, as necessary, replace the engine. Vehicles that pass inspection will be provided a higher viscosity oil, which will also require a new oil fill cap, an oil filter replacement, and an owner’s manual insert.

My 23 Chevy Tahoe was diagnosed with catastrophic engine failure on 04/02/2025, and per recall N252494000 a case for engine replacement. That replacement was completed and the case was closed on 06/02/2025. Since that time the new, replacement engine has been consuming oil at a high rate, is running with intermittent lag and I am waiting for a diagnostics appt with Chevy.

My vehicle’s engine has been recalled since June. The dealer refused to inspect because there is no remedy to replace the engine. I have complained since I purchased the vehicle of noises that I’ve heard. I am hearing more noises, and I am increasingly getting more scared every day to drive my vehicle. I will not put myself nor my family in harms way I can get into an accident. I am afraid to drive the vehicle. I am not taking any chances of hurting anyone else or my family or potentially have a fatal accident. two months of driving around scared I will not drive my truck anymore. I am beyond upset that there is no remedy for this and that it is not taken seriously. Something needs to be done regarding my situation and all others. The vehicle was sold, most likely knowing that this was a problem. GM needs to make good on this problem before people get killed. I would like them to buy back my vehicle, I am sure I qualify for a full re-purchase. I called GM. They will get back to me in five business days. I cannot emphasize how afraid I am to drive my vehicle and I paid $110,000 for this vehicle.

I took my car into the Fowler Chevrolet (AKA Century Chevrolet) Dealership in Broomfield, Colorado to get the engine recall addressed for my 2023 Chevy Tahoe-RST. I was told GM doesn't have a solution and has not sent any parts to the dealerships to deal with the recall. This is a significant safety issue/concern since I drive my [XXX] daughter every day in this vehicle. How is an OEM like GM allowed to get away with not having an immediate fix available to such a significant safety issue where an engine just fails and could fail without any warning lights on a highway. Extremely dangerous and nerve racking to drive this vehicle knowing there is this safety recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6

We were driving on a busy interstate in Knoxville, TN on a Sunday. We were 2 hours from home and my 2023 Tahoe basically went into limp mode while I was in the fast lane and the check engine light came on. No warning in advance. The speed reduced, which backed traffic up, and put me and my 4 children in danger. We finally got off the interstate and the vehicle had to be towed in to the nearest dealership. I had a friend drive us to enterprise where they put us in a Jeep Grand Wagoneer. On Monday, I received a call from the dealership stating they had good and bad news. The good news was the repair is covered by warranty but the bad news was it will be 2-3 months before they can get the part. The part is on back order and several people are waiting ahead of me. The said part is a valve body for the engine/transmission. The dealership also informed me that warranty will not cover a non-GM vehicle and that they will only pay for a rental up to 44.00/day. It’s not my fault the part is on back order, nor that enterprise gave me a non-GM vehicle. Also, I have a family of 6, which is why I have a Tahoe and I cannot be put in a small sedan. My children play sports, we have upcoming vacation, and quite frankly, I didn't pay 90,000.00 for a vehicle to be placed in a vehicle that I don’t feel is safe for my family. If I had wanted a sedan, I would have bought one. GM should take better care of their customers, especially when something is like this is not the customers fault!!! I have contacted GM and have been told I will be called back by a supervisor each time I talk to someone. This is unacceptable!!

Started having an issue a few weeks ago with the vehicle shutting off while driving for no reason without warning causing a very serious safety concern. This issue seemed to stop until one Saturday when i started the vehicle i noticed a small tick. This ticking sound continued to grow. The vehicle then shut off again with warning while driving. 7 days had gone by since the first episode. When I started the vehicle again there was a very pronounce rapping and it sounded like parts inside the motor were coming apart. When I arrived home i called Onstar. They did a diagnostic twice and said the motor was not showing any codes and running perfect. I had it towed from my house and upon inspection the motor is blown with 10,000 miles

Brought it to the dealer and they said that, that was normal. With the issues they are having with the engines, I wanted this to be noted, because blue smoke is indicative of either bad piston rings or bad valve seals.

Our engine (v8 6.2 liter) failed with out warning while my wife was driving. She said that while driving all of a sudden the dash started flashing telling her to restart the engine. The car just started shutting down. She had to immediately pull off into the median and barely made it out of the fast lane when the car stopped. She was so close to the fast lane that there wasn’t enough room for a person to stand without being hit. We had our Tahoe towed to the closest dealer thinking maybe it was an alternator. The dealer confirmed it was a failed engine and that our vehicle is the third vehicle on their lot with the same failed engine. All of the failed engine vehicles have right at 40 k miles plus or minus 1k miles. The only problem that we had noticed before the failure, happened that morning when I took the Tahoe to fuel up for my wife prior to her leaving. I noticed the engine cranked slow for a second before it started. I thought maybe the battery is just getting weak and that as she drove it that day, it would charge the battery. The exact failure as I understand it from the technician is “ the 5th cylinder failed in the lower half of the engine.” Apparently this is failing because the bearings weren’t properly seated during manufacturing.

On [XXX] while driving on the highway near Wash DC engine stopped, went to neutral. Would not start again. OnStar towed vehicle to Koons Chevrolet GMC Tyson in Vienna VA. 703 448 7221. On Tuesday Jan 7th, Koons Service Dept. looked at vehicle and determined that it was a thrown bearing and needed a new engine. There are 28,712 miles on vehicle. You can inspect if desired. Our safety was extremely compromised. We were on a 5 lane highway in the left hand lane going 65. Engine quit and we had to coast to the far right lane in heavy traffic. We almost got hit several times on the maneuver and rear ended on the side of the road from oncoming vehicles while waiting for a tow. Dealer has work order to fix the vehicle. Vehicle was not inspected by the manufacturer that we know of, nor the police or insurance representatives. Only inspected by the dealership. The only symptom before the incident was a dull sound like a plastic bag being stuck in the grill for a few minutes before incident. The Service Department said the parts are on a "Galactic backorder" which means they do not know when they will come in. GM is extremely uncooperative in assisting us with this issue. They will not repurchase vehicle, will not put in writing why they wont repurchase it. Will not provide any compensation until the issue is resolved, which could be months.

On Tuesday [XXX] Koons Service Dept. looked at vehicle and determined that it was a thrown bearing and needed a new engine. There are 28,712 miles on vehicle. You can inspect if desired. Our safety was extremely compromised. We were on a 5 lane highway in the left hand lane going 65. Engine quit and we had to coast to the far right lane in heavy tra]c. We almost got hit several times on the maneuver and rear ended on the side of the road from oncoming vehicles while waiting for a tow. Dealer has work order to repair the vehicle. Vehicle was not inspected by the manufacturer that we know of, nor the police or insurance representatives. Only inspected by the dealership. The Service Department said the parts are on a "Galactic backorder" which means they do not know when they will come in. GM will not repurchase the vehicle or tell me when the vehicle can be repaired. Will not provide any compensation until the issue is resolved, which is unknown and could be months.

On Sunday January 12, I was driving the vehicle on the highway with my cruise control on. The engine started missing the speed dropped a bit as the cruise control would not hold the speed. A mile or so later the vehicle engine started knocking with a metallic sound. I pulled over at the next exit and stopped at a store to look at the engine. There was nothing loose and a deep metallic knocking coming from the engine block, so I shut off the vehicle and called OnStar. At no time did any warning lights or other indicators come on. The gauges were normal. They/OnStar indicated I should not drive the vehicle, and they will tow to nearest Chevy Dealer for service and give me a $50 credit to take a Lyft to local airport to get a rental car. I was almost 4 hours away from home as I was travelling. After a week of turmoil with the local dealership I was told the vehicle needs a new engine. There is no ETA on the new engine as GM has to build it and has parts shortages. This was 5 weeks ago. I have been driving a rental since and there is still no indicate from the dealership about what happened or why. The vehicle is a 2023 and still under warranty but I am having to pay for the rental and request reimbursement which hasn't happened to date. There is very little information available, and I am in no man's land without a vehicle, so I have an open ended rental situation.

6.2l engine catastrophic engine failure with appt 17,000 miles on odometer. Kendall Chevrolet of marysville Washington has new engine on back order.

NHTSA #11640537

While sitting at an intersection of a busy 4 lane road the engine stoped without warning and could not be restarted. Due to a poor design by GM, the Tahoe has no ability to be put in neutral when the engine isn’t running. We were stuck at a busy intersection an almost hit multiple times, until a tow truck could come since it cannot be put in neutral and pushed. Dealer inspected engine and found it had been burning oil. The car never gave any warning lights that it was low on oil or that there were any engine issues. They did an oil change and gave the car back. The car was running, but within less than 5 miles of driving it it started to shake and make horrible noises. At this point, I was driving on the interstate. I was able to limp the vehicle back to the dealer. It was diagnosed by a dealer with spun engine bearing. I was told they were very close to seizing up and I would’ve been stranded on the interstate with no shoulder. This could’ve caused a major issue as I was on a busy interstate and the vehicle would’ve locked up. There was no shoulder at this point due to construction. Through both of these issues the vehicle never gave any dashboard warning lights. There are two major design flaws. The engine has an issue with its bearings. Also, there needs to be a way to put the vehicle into neutral while the engine is not running. It is not safe to not be able to put these vehicles into neutral.

Vehicle broke down on 12/1/2024. Had it towed to the nearest dealership. Dealership claimed that gasoline was pumped into the tank. We knew that wasn't the case. I called the store we last used for fuel and spoke to the manager. She was able to pull my wife up on surveillance and verified that she pumped diesel fuel from a "diesel fuel only" pump on 11/21/24. We also verified that the fuel in the holding tank at the store was actual diesel fuel. My wife purchased 23.45 gallons of diesel fuel. The tank size on this Tahoe is a 24 gallon tank. We had burned half of this fuel before the vehicle broke down. We also verified that no one else had complained about the fuel from the store. Dealership said it needed a new engine. We had it towed to another dealership for a second opinion, but they couldn't verify what happened because the 1st dealership had cleaned out the fuel system. I called GM but they won't help because they are going off what the 1st dealership claimed. Vehicle is still under power train warranty, but they won't fix it. This vehicle left us stranded on the side of the road. Insurance was called and a representative did go and look at the Tahoe. He called back and said that the issue does not fall within our policy.

While traveling on [XXX] approximately 20 miles west of Rawlins WY the vehicle entered “limp mode” causing us to drive at an unsafe slow speed. The transmission caused a check engine light to activate which was confirmed by a service technician in Rawlins with a PO747 code show on his OBD2 scanner. The problem was confirmed by the servicing dealer in Lincoln NE. The transmission was inspected by the servicing dealer. They replaced the valve body and fasteners approximately 1 1/2 months later. The problem first occurred at the time of the incident and I had no prior warning. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Transmission issue. Vehicle has the Duramax Diesel with 10-speed transmission. I am aware of issues with earlier year/s transmissions. I have experienced shuddering, jerking, a SINGLE momentary rear axle lockup. Jerky engagement from drive to reverse and or back. Reduced Acceleration warning on display. Check engine light comes and goes. Waiting for dealer to further inspect, drain fluid, etc. It appears from the VIN check that this vehicle had some metal work/paint prior to delivery to selling dealer, paint does not match. The transmission issue at 15,000 miles is just plain scary and not what one expects. That this vehicle sold as a 2023 has same issues as earlier model years makes me wonder if this is in fact a late 2022 model with the known defective transmission valve body? Any help appreciated.

NHTSA #11671104

Engine light came on. Flagged for a bad transmission valve body. Informed by dealership that the piece is on backorder and has been on back order for months.

NHTSA #11672560

My 2023 Tahoe with 76,000 miles went into limp mode and activated an engine light. The vehicle was taken to the dealership and had the code P0747 which is pressure control solenoid A is stuck on. The dealership technician is recommending a valve body replacement to repair this problem. This is a known problem by General Motors and has extended it to the 2022 models only. This is a safety concern that is causing rough irregular shifting, and a engine light to occur.

NHTSA #11662302

I noticed the gears of my Tahoe grinding when I would let off of the gas pedal. Eventually my check engine line came on. I brought it to my Chevy dealership. Upon inspection, I was told that my transmission valve body was bad and that I needed a new one. I was then told that my truck was ok to drive. I drove it for roughly another month until the check engine light came on again, and I heard the same sounds (I was able to catch it on video). This time, my truck would not want to accelerate past about 1.5 RPMs. I brought it back to the Chevy dealership which is where my truck is today. In hindsight, I believe I should not have been allowed to continue to drive my truck with a bad transmission part.

Our 2023 3L diesel Tahoe had 63,000 miles on it and went into limp mode (CEL on) in late April 2025. We took it to the dealership and they diagnosed the valve body as the problem. We continued to drive it (as they mentioned it would be months before a replacement part would be in) while I did some research and discovered the magnitude of the problem. Just google it! Meanwhile, the rear wheels locked up on me after I had picked up our two children from daycare. It felt like we had a log chain hooked to our hitch that snapped us back - really hard! Felt like we had been rear-ended. This could have easily caused us to get in an accident, or worse, but thankfully we were not in heavy traffic. Our dealership was able to provide us a loaner truck. Approx. 50 days later, we were informed that we were approved for a new transmission - which was also on backorder! Almost 80 days later, our new transmission has arrived and been installed. We are very disappointed with how GM has handled the issue. We were lucky our dealer provided a loaner, as many have not. There are after-market providers who clearly state the upgrades they've made to the valves bodies, and while GM says they've upgraded the ones they make now, they won't share any details. I'm aware of this same limp mode/rear wheel lock up happening multiple times (on the same vehicle) to people in very low-mileage vehicles (less than 1000 miles). This isn't a small problem, and GM knows it. We will see how far we get with this "new" transmission, but as you could guess, I don't have high hopes! I just pray that no one gets killed.

vehicle shutters when downshifting/slowing. Most commonly at cruising speeds between 40 and 50 mph, but does occur at lower speeds as well. Vehicle can be felt vibrating/shaking consistently every time it is driven. Was taken into a dealership, was not adequately diagnosed as it was only test driven 1 mile per the paperwork and they could not duplicate the issue and was told they were "in the business of making money to repair vehicles" and this was a warranty repair. While leaving a gentleman was walking in and happened to have the same type of vehicle and asked my husband what we were there for, turns out he was having the same issues. The vehicle shuttered the entire drive home after leaving the dealership and has continued since.

Vehicle down shifted hard and dash board lit up. Wouldn’t shift any higher than 4th or 5th gear. Fortunately we were only going about 35mph. If we would have been on the interstate as we had been the 2 previous days on our trip to Florida it could have been deadly. Brought the Tahoe to Ron Anderson GMC Chevrolet in Yulee, Florida on 3/18/25. The transmission valve body is the problem. As of today 4/11/25 we haven’t heard another word and returned home to Michigan 3 weeks ago.

While driving and accelerating the transmission malfunctions and wont shift so as I try to accelerate the car stops accelerating and just goes very slow. This put us at risk as cars were coming fast behind us. The problem happened 3 times before taking it to the dealership where they knew exactly what the problem was because it has happened to so many others. The warning light that came on was the engine light and a message that read "Reduced Acceleration Drive with Care"

The vehicle’s transmission began slipping at low speeds with less than 40000 miles. I took it to the dealership for diagnostic testing and the requested that I do “maintenance transmission fluid replacement” as well as some additional reprogramming which the dealer also deemed as maintenance. However, the required transmission fluid replacement was not required until 45000 miles and the reprogramming is not listed anywhere in the maintenance plan.

Traveling down the highway at 65 MPH the engine/transmission started bucking and you could hear the rear wheel lock up. The vehicle then would not shift and reduced the speed to 55MPH. Check engine light came on. Chevrolet is telling me the valve body needs to be replaced but keep driving it because it is on national backorder. After doing some research GM is hiding the issue and keeps installing faulty valve bodies. The GM fix is that they programmed the transmission to reduce speed when it notices excessive wear. GM is not standing behind the issue as it has been like pulling teeth to get a loaner vehicle.

I was driving my 2023 Tahoe on the interstate, in the far left lane. I had my wife and 2 kids in the car. Suddenly I noticed the air turned off and the dashboard screen went blank. I noticed that the car was now in neutral and the accelerator was not providing any response. I put on my hazards and started to merge across 7 lanes of highway without using brakes because we were going up a hill. We lost momentum in the second to last lane and could not move. The Tahoe then switched to park and the electrical system kept shutting off and rebooting. This also resulted in the hazard lights turning off for brief moments in time, so it was not effectively alerting other travelers of our dysfunction. (This repeated for the next 30 minutes until the battery died.) During that 30 minutes we were stuck in the lane with traffic buzzing around both sides of us honking and people screaming at us. My wife and 2 young children were upset and crying from the commotion. Poluce and emergency response team arrived, flagged traffic and drug the vehicle off the road.car was stuck in Park, with no ability to move to neutral. So tire rubber was smeared across the last 2 lanes and into the right shoulder. Later a tow truck arrived and hauled to dealership. The car had ~11,000 miles and bought the vehicle 2 months ago. This should not happen with new cars.
