There needs to be a better system on alerting used car buyers. When I purchased my car from Carvana used in 2017 at 83k-ish miles, I had no idea that there was an extended 10 yr/120k warranty on some models of GM vehicles. I have been experiencing issues with my car and just learning 1 yr and 30k miles too late that there were known issues, and that my issues most likely were related to the timing chain. Timing chains aren't generally something that wear out by 100k - had I been made aware of that when I purchased the car, then that would have been the first course of action. I checked the VIN, no recalls, but no extended warranty alerts either. Anyone else having issues would not have known other year models were experiencing problems that could have affected different year models as well. I have researched my cars issues and I have taken it to mechanics- even to a Chevrolet dealer when I first bought it. Absolutely no mention of this, until I just happened to stumble on a Cadillac forum post from 2019 at 1 am 6/2/2021. Now I am the almost owner of a car that books out at maybe $5k with over $2k worth of work that is needed. It sits while I make payments. With all the technology, there should be some way for car dealerships to have to give a new owner any updated information regarding any vehicle related to the one they are purchasing.

I have read many forums with this exact problem. My car will get out of gear when I'm at a stop. It will act as if it was in neutral. There are no codes that tell you what is wrong and so many people have found that the issue is that the automatic transmission clutch goes bad. I only have 88K miles on my car and so many people seam to have the exact SE problem as I am.

2010 Cadillac cts4 premium 3.6 wagon I replaced the rear prop shaft of the AWD system in January 2018. I now am having issues with the rear prop shaft yet again, not 2 years later. I believe the driveshaft carrier bearing is failing again (same as before)! with approximately 49K miles on it. I cannot believe that I have to replace this same item again. After having to replace the rear differential twice on this vehicle, I now believe GM has no clue to make a reliable AWD vehicle. Worst car ever.

Vehicle died while driving with no prior warning or error messages-complete engine failure, loss of power steering, brakes. Unable to restart after several attempts. Mechanic determined that the ECM had failed unexpectedly. When computer was replaced, they were unable to detect any sensor issues that may have contributed to ECM failure, they concluded that the ECM had failed while driving. Had it failed on freeway, results could have been catastrophic.

My car while driving on the highway has turned off out of nowhere while driving 60 mph while the car is still moving I put the car in neutral turn the ignition off N then back and the car turns right back on but some days this happens more then others. This problem has been going on for several months I have been in and out of the dealership. And they still to this day can't tell me what is the problem. But I have done research and there a lot of these incidents going on with GMC vehicles idk why they say they can't find problem or fix it. They just want me driving on the highway with my family when the car stalls out. This problem isn't everyday it seems to happen 3-5 times a month. I don't remember the exact dates but this problem has been going on since I got the car. If the dealer can't tell me what's wrong what am I suppose to.

The car shut off while driving down a hill this is the second time it has happened I checked with GM to see if there was a recall for this car and at this time there is not. We were lucky both times that there were no other vehicles around and that the car was kept under control while bringing it to a stop. Although GM has no recalls for this car I am filling this complaint because of the many recalls that are out there for this same problem. Will the third time be a charm when it happens and someone gets killed or seriously injured for GM to include this car? it will be to late!!!!!!!

The contact owns a 2010 Cadillac Cts. The contact stated that when she depressed the accelerator pedal, the vehicle was slow to accelerate. After a few seconds, the vehicle would move forward as if it had been rear-ended and then the speed would increase. The failure occurred numerous times. The vehicle was taken to an authorized dealer several times but the failure could not be determined. The transmission fluid, piston, filter and fuel kit were replaced but the failure occurred. The contact called the manufacurer who took a complaint and stated that they would try to correct the problem. The failure mileage was 1,819 and the current mileage was 3,324.
