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.

On several occasions over the past 3 months the car would "jolt" while accelerating in the 20 to 30 mph range so bad it felt like I was hit from behind. Felt like the transmission got caught between gears. Took the car to the dealer and had to pay over $275 for diagnostics and reprogramming even though car was still under the power train warranty. The dealer did not know if this was the fix. Very disappointed this wasn't covered under the warranty.

The drive shaft needed to be replaced at 65,000 miles. The headlights look like they are not on at night when you are driving. There have been 2 class action lawsuits won in California and Florida for these defective headlights. I don't know why they would not include all the cars that had these headlights because they are all defective. If I would have known this I would not have bought the car. I have owned it 4 months and the touch screen cracked, driver assist seat control stopped working, the drive shaft needed to be replaced and the headlights do not look like they are on at night. I feel like I have to drive with my high beams just to see adequately and safely.

We stopped at light or stop sign, when taking off here a loud boom or kick.

- Youngstown, OH, USA

While at a dead stop and then trying to accelerate, vehicle will have a lag before any acceleration occurs. Lag can be from 5-10 seconds. Has happened several times over past 12 months. Extreme safety issue. Been to dealership each time, but they cannot reproduce and no diagnostic codes appear. 3.6L engine. I see that a recall for a very similar issues was performed on 2013 model year Srxs. That recall required reprogramming of transmission control system. Same issue"??"

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.

On inclined or hilly terrain the car rolls back even if in drive. After a complete stop due to traffic or stop sign or signals, when foot is taken off the brake pedal, the car begins to be rollback instantly. Such sudden shift of gear is scary. Reminds you of all the accidents caused by automatic shift of gear. It is a major safety issue. Never had experienced such roll back in the GM cars we previously owned. And they were less expensive cars. The car was bought in novi michgan and was taken to Virginia. It was driven around Washington DC metro area for almost one year. The issue was reported to a dealer in Virginia and Michigan. Not much attention or importance was given. In novi, when asked for documentation of our report, was told it is placed in the system the gps system in the car at occasions have given wrong directions, which it attempted to correct at the last moment requiring immediate and quick maneuvers. That itself causes grave safety problems in multi lane roadways. The gps system I'm the I phone is actually better and more uptodate. The spoken instructions are not as clear as other systems. The dealer said they were not equipped or trained to correct this problem

Car was making whistling/howling sound between 30mph-45mph. Thought possibly a breaking in issue, but continued after 1200 miles and was most prevalent at stated mph above. Shop stated bearing issue in drive shaft and entire drive shaft must be replaced. Concern over effect to other power train parts connected to defective drive shaft. Could not be driven until parts replaced. Definitively, a safety issue.
