An ac clutch/compressor malfunction. No cold air, unusual noises (grinding, squealing, rattling), metal shavings, burning rubber smell, engine stalling. No warning lamps or messages ever appeared. The problem was serviced at independent service center. The nearest gm dealer is more than 40 miles away from me. Did not drive vehicle and seeked professional help immediately.
The car was at a red light so it automatically stopped. When the lights turned green, I removed my foot from the break and the car would not move. I had to call onstar for roadside assistance and they called the police to make sure I was safe and that traffic flowed safely. My car was towed to the dealership after they tried to start the car by the key and my jumper cables. The car would not start. The dealership is unable to start the car as well and they are saying that the issue with the fuel pump is not under the most recent recall for my VIN number. I was able to locate the recall for the same exact issue that I’m having under my VIN number on the GMC website. I have filed a report with the GMC manufacturer to try and get this issue fixed. I have brought this car in multiple times to the dealership I purchased from and an additional dealership to show them the issues that I have been having with this car starting and stopping, I could have been ran over by a public transportation bus today.
The backup camera on my vehicle stopped working completely, displaying a blank screen. All other cameras and sensors continue to function normally. The dealership identified the issue as the camera having “shorted out” and is replacing it with a completely new unit. The faulty camera is currently with the dealership, and I assume it would be available for inspection upon request. It is being replaced and I will receive a bill in a few days (Wednesday March 10, 2025). The backup camera is a critical safety feature designed to prevent collisions with pedestrians, objects, and other vehicles when reversing. Without a functioning camera, visibility is significantly reduced, increasing the risk of an accident, especially in crowded parking lots or areas with low visibility. The sudden and unexplained failure of this system is a serious safety concern. Yes, the dealership confirmed the issue when I brought my vehicle in for inspection. They determined that the camera had “shorted out” and ordered a full replacement. The vehicle has been inspected by the dealership, which is handling the replacement. To my knowledge, no manufacturer representatives, police, or insurance agents have examined the issue. There were no warning lights, error messages, or other indications before the failure. The backup camera was functioning normally, then suddenly stopped working, displaying a blank screen. I have heard that Cadillac and GMC acadia models have experienced similar backup camera issues, leading to recalls due to sudden failures. Given that my vehicle’s camera “shorted out” without warning, I believe this may be part of a broader issue affecting gm vehicles. If this is a recurring problem, it poses a serious safety risk and should be investigated further.
Driving 75-80mph in the freeway when suddenly the power stopped in the middle of the road and couldn’t get it to run. Thankfully freeway exit was near was able to get the vehicle to safety. Tried to turn in on again and would turn on but die down after. Had to tow the vehicle and take it to the dealership the next day. Said it was fuel pump module defect and there’s nothing I could have done to cause it. Vehicle is less than 3 years old with good maintenance.
I had an issue with the all wheel drive system. The message service all wheel drive system appeared as I was driving the vehicle. They found a rear differential module software issue 2810695. They found dtc c056d stored in rear diff control module. They programmed rear diff module and retested. Claim code is 1byn199108119. I do not have any parts but I was told that they send warranty components back to the manufacturer for inspection.
On Aug 3rd 2023 I was driving east on a michigan highway when the service transmission warning came across the dash then the car shut off while driving 60mph. When trying to steer the car to the side of the road I noticed the car was in park(this car is equipped with push button shift). The car shutting off made it very hard to steer. If the traffic was heavy this could have caused an accident. I do have a video of this happening.
Vehicle started stalling back in February 2023, service engine light started coming on and then we started getting a message that the sd memory card had been removed and this message has stayed on constantly along with the service engine light. I made an appointment to get the recalls fixed with the dealership that we purchased it from which is 50 miles away but was told the parts for the fuel pump and child restraints were not available at that time. They looked at the memory sensor card but could not find anything wrong and was told if the error message came back up to call them back, I know more got home and the message came back up so I called them back and they set me up with another appointment the following week. This time because the message only comes up randomly and it did not come up while I was there I was told nothing could be done but to call back when the message comes back and as soon as I got home it came up so I called them back, they made another appointment for the following week and this time the message came on when the tech drove it so they took out the sensor card and cleaned it and everything around it and said everything looks fine now but it still comes on, but was told due to them not having the parts for the fuel pump that we should take it to our closest dealership. On 6/15/2023 we took it to our local dealership and I was told they would need to order parts and the eta on it was 4 days out, they said they would call me when the parts came in, I waited until 6/22/23 and no one ever called me back so I called to check and the parts were still not in but would check on it and call me back, no one ever called and I still have not heard from anyone. The last time we took it up there the vehicle stalled, we almost got hit from behind and it kept dying and would barely start, it is now setting under my carport, we are afraid to drive it and I still have not heard from anyone. This all started in February 2023 and it is June now.
April of 2022 I purchased this car brand new. January of 2023 this car started to have a musty/mold smell. I took it into the dealership in late February and inquired if this was a reported problem. I did as they dealership said and replaced the cabin filter. The cabin filter was black at 9,700 miles. It smelled horrible. On April 6, 2023, I took my car into the dealership to resolve this smell. It was discovered that the the cowl inside the firewall on the drivers side firewall had several holes and an incorrectly applied seam. It was also discovered that the drivers side sunroof drain was also disconnected. This was was full of mold. They replaced the entire interior of my car which took until June 28th. I expressed I did not want this car back for fear of mold, I had already been sick and had no idea why. Once I got into a dealer car, I quit coughing. The dealership cannot guarantee me that they got all of the mold in the car, it still has an odor in it. I have went through the claims process with gm and they have refused to buy back my car, based on my claim I am worried about my health. This car had $12,000 in repairs to it. I was promised verbally by the district manager of after market sales that my car would be bought back. They backed out on the deal and told me they cannot buy it back for destruction. I have great concerns about my cars safety with the mold being so large. They cannot guarantee me the mold is completely gone as told me to by the service manager. Therefore, this would include the safety of others that travel in my car, to include children and older adults. This problem started in manufacturing and was acknowledged by the dealership as such. It was a defective car when it arrived on the lot.
The dealership first told me to take it in and I did and then they told me there is nothing they can do to fix it and it’s dangerous to be having my car with the recall and they know what to.
My wife was driving to work when the sunroof just exploded. She said there were no vehicles in the oncoming lane nor was she following anyone. She heard a loud sound and glass came in landing on her from the sunroof. Right now it is currently at the gm dealership to be investigated by their service department.
