On Monday, August 5, 2024 when I started the vehicle and began driving to work I noticed upon startup the engine was clearly noticeably louder. It also made a strange bogging downshift type noise when idling. Upon driving, the noise seemed to go in and out but once reaching approximately 40mph the noise got noticeably loud again and the vehicle seemed as though it was having gear shifting issues. I had the transmission fluid flushed and filled costing me $300. This seemed to help but very little.I did research to find recalls on the vehicle and found -??Special Coverage 18029, Reference # N172115200-??, which is an Inoperative Purge Solenoid. THIS IS A DEFECTIVE PART INSTALLED BY MANUFACTURER. I was unsure if this was the issue with the vehicle however doing research it was very possible. I contacted GM more than once and was stonewalled. All they said was to contact my local Cadillac Dealership to have the issue diagnosed and repaired at my cost. They offered no resolution although it-??s a defectively installed part by GM at the factory. Engine light came on for the first time Thursday, 01/09/-??25. I used the diagnostic computer tool from AutoZone and the printed results showed it was in fact the Engine Variable Valve Timing Solenoid and Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A -??Code P0016-??. The vehicle has been dangerous to drive nearly stalling out or unable to shift smoothly nearly causing an accident several times, as well as loud and giving off dangerous noxious fumes. GMs refusal to fix the vehicle due to their negligence in factory installing a defective and faulty part, as well as the rear passenger side Tire Pressure Sensor Monitor (TPSM) shows the unconcern for their customers safety and satisfaction with their product and underscores that seemingly their only concern is their own monetary profits and refusal to amend and resolve dangerous mechanical issues caused by their own doing.

-I was traveling South on fm, miles North of miami, tx when a deer ran out in front of me. I struck it front center and onstar immediately called for emergency services. First thing I noticed was one of the air bags deployed and after pulling of the road and coming to a stop, I noticed a fire from the passenger side of the engine compartment. I exited the vehicle and still on the phone with onstar, my car fully engulfed within 15 minutes. The fire department was on site after the car was fully engulfed and took an hour to put out the flames. My car was a total loss. No one knows why it caught fire, what caused it.

While driving on the highway, the stabilitrak and check engine warning indicator lights come on. Next a warning reads, "engine running at reduced power" and the car slows down. When I cut the car off and restart, the warning indicator lights reset and the car will drive normal.

I've been having the same problem as another driver with the exact same situation. It seems like we're both having the same problem, and we're both being ignored. When accelerating, car lunges forward and kicks back when transmission is changing gears at relatively low speed. Car has been brought to dealer (patrick Cadillac in schaumburg, il) numerous times but dealer claims it is a normal condition. When pressed the service manger admitted it is normal but on the extreme side but refuses to remedy the situation. I believe the car is unsafe and should be repaired. GM corporate has been has been contacted on numerous occasions and is uncooperative and refuses to return any communication. When one pays the money to buy a luxury vehicle, one expects problems to be taken seriously and repaired.
