“I bought this vehicle in August 2025 and October was the first incident that this occurred. What happened was I was driving to pick up my husband and all the warning lights on my car dash started going off and then it died. After we got it started again we took it to the nearest GM dealership and after we parked, we could not get it to shut off then when we started driving again, it died in their parking lot. This has happened multiple times since.”
NHTSA complaint #11715974, filed 2026-02“I purchased my 2025 GMC Acadia on March 26, 2025. // My vehicle began to have electrical/communication/system issues in August 2025. // I took my vehicle to the dealer to address these issues at this time.

You need to contact OnStar about this. // I called OnStar, and they ran a test, and stated that it is a manufacturing defect that needed to be handled with GMC. //No one informed me of the severity of the safety implications involved. …”
NHTSA complaint #11729184, filed 2026-04“This is ongoing from the purchase of the car. 1) Infotainment computer screen daytime illumination is so dark as to be a major safety issue as it causes too much time looking away from the road to operate the system. If you wear sunglasses you cannot see the screen at all. The dealer says nothing can be done to improve the problem. 2) Right rear tail light stopped working after 500 miles. Replacement requires dropping the rear bumper and quarter panel. The dealer actually damaged the body of the car while replacing the light. Where are the days of changing out a light bulb? …”
