Started hearing sounds on both sides of the car while driving. A sound that got louder the faster we went. Driving home on a 65 mile journey, about 12 miles from the house the ABS, Brake, and traction control lights all came on and stayed on. The car felt like it was much harder to drive. Pulled over safely and picked up the manual. Not much in there. Did a quick search on the web and found that this issue seems to be a long standing issue for my model car but that I could try to drive it home but do so with extra...

caution it don't drive if the roads were wet. Roads were dry. Made it home and started checking fuses, battery, brake fluid and such Finding all apparently working. Took the car to a service center and explained the problem. He shook his head and said it's likely the EBCM (electronic brake control module) and that he's seen lots of them come in. He continued that the issue is that GM has discontinued the EBCM for that car and others. I asked him to run diagnostics and provide me with the codes shown. Unfortunately he was spot on when I saw the print out showing code u056D Brake control module failure. He goes on to say that parts can be hard to find. Checked with Cadillac and sure enough they don't make the part any longer and as such I'm on my own. They could offer me a discount on a trade in but cannot fix the car. For real? When the EBCM goes out it's designed to limit some of the vehicle controls like braking and traction control. Why no recall? Why create a safety issue that you are unwilling to fix. My wife has to drive 65 miles to help her 86 year old mom but this car is now very limited and not safe. My repair shop called and he found a used replacement at $900 not including the $700 price of reprogramming the VIN into the module and installing the part. Seems a recall should be implemented with Cadillac finding a reasonable solution for their customers. Without repair the car is not safe.

OnStar taking control of vehicle suspected of causing timing belt to skip timing supported by Chevrolet Ourisman of Bowie. Paid $800-1000 to Ourisman for service and diagnostic. Ourisman suggested engine needed to be opened to fully inspect or replaced for $6-8000. A piece of the sensor was claimed to have broken off and fallen into lower engine manifold. Vehicle would rev when stopped and putter to halt. Vehicle would start and stick in second gear up to 40mph until stopping and refusing to start. Engine replacement evaluation reconfirmed by Foreign Auto Parts of Annapolis, MD after explanation. Chevrolet of Silver Spring attempted to buy car for $100 after suspect inspection.

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...
