GMC Complaints

Multiple times the windshield wipers have randomly stopped working. Other times were on short drives from home and we were able to get home safely but had issues with visibility. Eventually they would come back on and start working again. Yesterday this occurred while we were out of town and driving home on the interstate in traffic and very heavy rain. It was almost impossible to see the road and due to multiple lanes of traffic it was a very dangerous situation. This is an huge safety issue and has now put my families safety in jeopardy on multiple occasions. Other drivers have also reported this issue.

While driving the vehicle shut off, leaving my family stranded in the middle of traffic. It was a 90+ degree day and my family was stuck in a hot car unable to move off the roadway. This was very unsafe. No warning lights prior, the engine just stopped. After multiple times trying to restart the vehicle, the battery died. After waiting several hours, the vehicle was towed to the local dealership where it was determined that the driver fuel control module needed replaced and re programmed.

Car driven off the lot 06/14/2025 On Sunday 07/06/25 (21 days from purchase) while driving home from a 30 minutes away from home trip with 3 young children with me, the car gave multiple alerts and service warnings. "Service Brake Assist" and "Service ECS" Lights / Symbols related to the following were also displayed: Traction Control System (TCS)/ Electronic Control Stability Light, Anti-lock Brakey System (ABS); Brake System Warning Light, Forward Collision Alert and BREAK light I stopped the car immediately and pulled to the side of the road. After restarting vehicle, lights were still displayed and service alerts still on. Power steering was very diminished and the breaks were struggle to break. Acceleration was also impacted and every time I breaked it appeared as though the car was trying to accelerate. I was able to drive the car home slowly following back roads. On Monday 07/07/25 I called the dealership and arranged a tow to their facility. On Tuesday 07/08/25 after multiple "unavailable to take your calls" I was finally able to connect with a service technician who indicated the break master cylinder needed to be replaced. I was not given an ETA on the completion of this repair. I have owned the car for 21 days. It has 1073 miles on it!!! I have 3 young children! The original route home was via a very heavy interstate! What if the brakes failed me while driving an interstate! I praise God I was able to get home safely with my children
