The car unexpectedly braked. There was nothing in front of the car & I was traveling only 20m/hr. The car stopped so abruptly my sunglasses flew off. Then i was hit from behind by a landscaping truck.

While driving the complete dash will go black: no radio, gauges, speedometer, etc. The total blackout lasts for about 30-45 seconds and then different gauges, speedometer, etc will slowly come back to life. During this blackout period I have no idea of my speed nor what other functions, like ABS, might be off-line also.

Purchased used with 30k miles and under factory bumper to bumper warranty. Noted noise when turning right slowly into parking space from front suspension as well as pop sound while going over speed bumps. Dealer replaced 3 axles (2 driver side) and confirmed noise present. Also replaced strut assembly in front which did not assist. Suspension issue unresolved to date and GM Field Tech suggests “operating to spec”. The main issue noted is the leerching forward between gears when braking to a stop. It’s as if car is sliding into each gear , learching while brakes applied, until stopped. This could cause accident and harm to occupants. Transmission is the 9 speed T950. Dealer replaced valve body and fluids and then Field Tech revisited and said “operating to spec”. It is unknown if issue related to transmission, electronics shift coding , or torque converter. I currently own 4 GM products and have owned over 20 without this issue.

The automatic emergency braking system suddenly engages without any obstacles/pedestrians in the roadway causing the vehicle to completely stop. The vehicle is at the dealership at this time; it is unknown if the dealer can confirm the issue. The vehicle has not been inspected by the manufacturer. There was a warning light flashing directly before the incident(s).

I was driving down the road and my vehicle lost power and quit running. Luckily I was in the lane closest to the shoulder and was able to pull over on the shoulder and was not able to restart my vehicle, but had this happened in another location this could have been a huge safety problem for me and others with the vehicle completely losing power while driving in the middle of traffic on highway 27. The vehicle is still under warranty and has 10k miles. I am the only owner of the vehicle and it has only been serviced at the Cadillac dealer. The Cadillac dealer was able to inspect my vehicle and determined that the fuel pump module went bad and replaced it and advised that this has happened to other Cadillac, GMC, and Chevrolet suvs.

Automatic emergency braking activated on three separate occasions when there weren’t any reasons for it to engage, additionally if there were any cars behind me I would have been rear ended since they would not have anticipated me stopping so suddenly.

Vehicle died leaving the doctor's office due to faulty fuel pump driver control module. Upon research found that this has been an ongoing issue for several years affecting many GM vehicles. Vehicle can stall at any time in traffic causing serious injury or death. Apparently GM does not have a fix for this problem & the company's solution is to replace the faulty module with modules that have the same defects. Also, when affected vehicles stall in traffic, the parking brakes set & there is no way to even put the vehicles in neutral so that they can safely be moved out of the roadway. This increases the chances of causing a serious accident if one was not caused by the initial breakdown. GM should not be allowed to sale these vehicles with faulty parts putting countless lives in danger.

The vehicle has a chronic defect causing rapid, repeating front-end suspension and steering assembly failures. The right front strut and mount failed and were replaced under warranty twice in 2025 (at 29,968 miles and 35,740 miles). In May 2026, the left front strut and mount failed and were replaced. Two days after picking up the vehicle, a cascading mechanical failure occurred when the left front CV axle boot split, covering the wheel well in grease and requiring a complete CV axle shaft replacement. Following these consecutive teardowns, the dealer omitted a mandatory safety wheel alignment. The vehicle was returned with a severe lateral steering pull and a steering wheel forced to the 1 o'clock tracking position while driving straight, causing extreme handling instability on public roads. The manufacturer refused to authorize a warranty alignment to fix this safety hazard, forcing an out-of-pocket expense at a separate facility to make the car safely drivable.

I was getting out of a parking lot with my 3 kids and the car shut off right in the middle of the entrance/exit of the lot blocking anyone from coming in or out. The car would not go into neutral to move it, making it unsafe for my family and everyone around us. We tried to charge the battery but that did nothing. We called tow truck then where told we need a special tow truck since the car could not be put into neutral. We waited hours for a tow truck, when we finally go there, the car's emergency breaks keep coming on and would not turn off. We ended up removing the battery. I was told that it was the Module fuel Pump shorted out, it was a common issue. I asked how we could put the car in neutral and he stated that there is no way to put the car in neutral when this happens, which is a safety issue. This should be a recall. I have the app that is supposed to alert me if there are any issues, nothing showed until after the call shut off, even then all it said was that the battery was low followed by an issue with the fuel management system.

Problem with the fuel pump control module. Car broke down in front of my neighbor’s house. Now there is a problem with the transmission. It is slipping and there’s a clunking noise.
