2017 Cadillac XT5

I purchased the car on XXX. The car has been returned to the service department within the first 3 days. Sold to me without getting fully inspected. Service department did put new brakes and rotors on and I was told (no paperwork given to me) an oil change was done. On XXX in traffic on a dangerous highway, the car cut off. The car was not able to be jumped with AAA, was towed to [XXX]/GMC Service department. I was told by the Asst Svc Manager, on XXX the Tech told him My car was the starter. The part would have to be ordered and would not be ready to the following week. On July 7th I received a call from the SVC Mgr that the engine blew. I had to pull teeth to get the Mgr to pay for the engine of $8500 and yet he wants me to pay $1500.00. With having a car less than 21 days regardless if I went over the 3k miles and as -is, there was a 90 day warranty when everything should be covered. He has now rescinded because I reported this to BBB, Atty Gen office, NHTSA. This car was never inspected. I requested the On-star reports, Inspection reports for the last year and the Tech's findings and nothing has been provided except one. I requested several times the service report and the General Manager/owner is so upset, he submitted nothing.I have felt intimidation throughout this entire process.

I purchased this used car in the end of July 2025. Within the last month the service transmission light came on. Within a 24-hour period, the message changed to, "service transmission unable to shift Soon". Also alarm bells go off when I first start the car and sometimes during driving. The car feels like it drives correctly and smoothly with no shifting issues. Sometimes when that second message and check engine light icon being comes on, there seems to be a third message that is trying to pop up behind it but it does not. It seems like there is a glitch in the system. This was very concerning and scary for me. My research shows me that this has been a chronic problem for my make and model and year of car. I've also heard it can be even time to check and or change the transmission fluid. That needs to be a different message all together without causing alarm that the transmission itself is not functioning properly. I have not driven this for 10 days because many repair shops in dealerships are telling me not to risk it and of course want me to bring this in for a diagnosis. It is costly and hard to discern and trust who to go to for the correct information. The dealership should be responsible for a recall and replacing this sensor or modular so people do not have a cause for alarm if it is something as simple as needing to change the transmission fluid. There is also no dipstick on this vehicle so no local fluid fill station can check this. Many people have complained and are at a loss. I see there is a bulletin on this subject but no recall. Please take action and turn this situation into a recall once and for all to help. The little folks like me stay more safe and better informed about the health and longevity of our vehicles. Thank you for your time in reading this.

In 2021, I took my car into a GM facility to be repaired bc the A/C kept going in and out. Car was under warranty, however, GM mechanic just did a “bandaid” fix and replaced the thermostat, when there was a service bulletin put out in 2017 for this very issue. 3 years later, my car is having the exact same problem, and since car isn’t under warranty, GM will not fix it, even though I have proof they didn’t fix it correctly the first time. The service bulletin is titled, “17128: Service Update - Potential Loss of HVAC Control- (March 30, 2017) This issue started in October 2021 the first time, was temporarily fixed. It started again in October 2024 and is ongoing.

My car has been in and out of the dealership since [XXX] All the lights come on ( check engine, ABS ,the message reads park assistance off all the lights The car goes crazy and stops running. This happened 3 times on the highway almost got rear ended. It is very scary I can not take this chance anymore. The dealership keeps changing one module after another and keeps telling me it is fixed. However it is not The car is in the dealership ship as of 10 days ago again. I will not pick it and drive it. Either me or someone else gets killed. I also opened a case with GM. However they just keep doing nothing. This matter needs to be addressed asap There is a serious problem, before someone gets killed. My name is [XXX] [XXX] [XXX] Can someone please get involved or I will go on TV or the newspaper if I have to.

At approximately [XXX] on [XXX] ,2024 I was at the intersection of [XXX] when my vehicle stopped running completely. All lights on the dash went out and the doors were locked which prevented me from exiting the vehicle. No systems would operate at all. All I could do was sit there. Fortunately, I had a cell phone with me. I called my local Cadillac Dealer for advice, they had very little. finally a lady there told me she would call a tow company they recommended, which she did and the tow company, Shawnee Auto Body did respond about 20-30 minutes later. In the meantime, a gentleman from a local tree company arrived on the scene and helped me, by placing an orange traffic cone behind the vehicle to keep oncoming vehicles from rearending me. after a few minutes the doors did finally allow me to exit the vehicle, which I was unable to do earlier due to the doors still being locked. Upon exiting the vehicle we raised the hood and discovered the negative battery cable was loose causing all power to vehicle systems to be lost. was the cause of the problem. The replacement Intrstate Brand Battery that i have in the vehicle negative post is smaller than the automobile cable that comes on the car and apparently when the man installed the replacement battery he failed to notify me he was unable to tighten the cable as it should have been which allowed it to become loose and vibrate off the post over a period of time. This is a major problem that needs immediate attention. What if the vehicle would have been on fire or something? I would have been trapped in the vehicle and unable to escape due to the doors remaining locked when power was lost.

While driving the vehicle started to accelerate in its own. There was nothing obstructing the pedal. I could press down on brake with some resistance, but as soon as brake was released the, the vehicle accelerated. The vehicle did not level out with speed but continued to accelerate over 80 mph. This lasted about 8/9 mins, being controlled by riding on the break. It did it again for about 2/3 mins about 15 mins after first occurance. I took the car straight to get it looked at and the mechanic said that they could not find anything wrong with car
