2019 Cadillac Xt4: Recalls, Complaints & California Lemon Law

I took my car is for service at the Cadillac dealership and they stated there was an oil leak from the camshaft carrier. When I asked more questions they stated it was a fairly common problem with the XT4 and a few other models where there was a faulty seal at the "T-joint" (cam carrier T-joint). My car is no longer under warranty, but had under 26000 miles at the time. There were no warnings or symptoms. I would not have not if the dealer had not told me. The cost was estimated at $3254.45. If this is a common problem, why isn't there a recall?

During oil change Cadillac mechanic noted camshaft oil seal leak. Video was provided. Mileage on car is 51,534 at that time. I feel that this is too premature and repair requires pulling the engine. Very expensive. Quote was $4,597

At around 17,000 miles the timing chain tensioner went bad. At cold start up you could hear the timing chain hitting the 'guide' until the oil pressure built up and provided enough tension. I was covered by an aftermarket warranty - which paid all the labor ($1700). I had to pay a $100 deductible -along for the parts ($300). I feel that this should be looked into and Cadillac should replace any tensioner that might be defective- since this could cause catastrophic engine failure. If you check - it does appear the 'new tensioner' part number is a revision- indicating Cadillac probably knows the old part number was defective!

The passenger side DRL/turn signal is dim causing the vehicle visability to be reduced and other drivers unable to see turn indications, increasing the risk of crash. The design of the unit places undue heat near the circuit board causing the unit to fail. The driver's side does not have this issue. This is a known issue with many post on forums on it.

Toward the end of October 2024, my truck's check engine light came on. I took the vehicle to the dealership to have the oil changed. Two days later, the engine said, "Engine power reduced," so I took it to a repair shop, and they diagnosed the timing chain. I took it to another repair shop for a second opinion, and they also diagnosed the timing chain.

Recently went to my local Sewell dealership for my routine oil change. With an oil change they do a complimentary multipoint inspection. During the inspection they noticed that my camshaft carrier was leaking and needed to be resealed. The resealing of the camshaft carrier would be around $4,000. I don’t have that kind of money laying around especially in this economy. I just got a new place and I can’t Afford to spend $4,0000 right now. I did some research online and apparently this is a common issue with Cadillac cars. I reached out to other Cadillac owners and they advised me to submit a complaint with the NTHSA due to the frequency of this issue across Cadillac cars. Will there be some type of reimbursement/recall to fix this issue because if it happening across multiple Cadillac cars no matter the make or model, this should be on GM/Cadillac to fix and not the consumer.

In September, my vehicle would not start. I had it boosted and it started right up. The very same afternoon , it would not start and had it boosted. Drove it for 2 days without issue and on day 3 it would not start and boosting was unsuccessful. The vehicle could not be put in neutral and needed to be towed. The car spent several weeks at the dealer and I was told it was the battery which I replaced the key FOBS needed to be reprogrammed and then the wiring harness was chewed up. After several weeks at the show and over $1,000 later the car was returned. A month or so later , the car wouldn’t start, could not get boosted and had to be towed back to the dealership. After 2.5 weeks , I was told it was corrosion on the wiring harness. I’m concerned that these issues will persist and I could end up stalling in the middle of the highway, Vehicle only has 31,000 miles on it.

The throttle and accelerator pedal is very HOT- highly sensitive, resulting in jerky lunging upon start off in 1st gear from a dead or 1 mph stop. The vehicle has been into the dealer 2 times for this issue with the same repair comments, vehicle meets all factory specs and all XT 4 react this way- well that's not safe. If that's the case, then this is a design defect which is unsafe as the accelerator pedal reacts to quickly with a non-smooth action and lunging which could cause a rear end collision. Other car evaluators have also indicated the XT6 has a jerky accelerator, just like what I am reporting. It may be the TPS -Throttle Position sensor in combination with the APS-Accelerator Position sensor. Sometimes it is so violent it throws occupants backward into the seats. Dealer says within spec. GM needs to solve this issue.
