The contact owns a 2024 Chevrolet Suburban. The contact stated that while driving at approximately 30 MPH, the steering wheel locked at an angle, and the message "Power Steering Not Active" was displayed, causing the vehicle to strike a curb. The steering column, control arm, radiator, fender, and wheel were significantly damaged due to the incident. The vehicle was then towed to a dealer, where it was diagnosed that the power steering module had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and an investigation was completed. The failure mileage was 58,277.

On May 2, 2026, while the vehicle was in operation, the engine suddenly shut off without warning. At the time of failure, the instrument panel remained illuminated; however, the vehicle would not restart. In an effort to resolve the issue, the battery was replaced, but this did not correct the problem. The vehicle was then towed to a local Chevrolet dealership for further inspection and diagnosis. Following their assessment, I was informed by the dealership’s service department that the engine had seized and that metal debris was present in the engine oil, indicating significant internal engine failure. I was further advised that a replacement engine has been ordered. At no point prior to this incident were there any warning indicators, abnormal noises, or performance issues that would have suggested an impending engine failure. The sudden nature of this incident raises concerns regarding the cause of failure and whether it may be related to a defect or internal mechanical issue.

1. Sunroof 2. Driving on 81 N slightly past the Middlesex exit at highway speeds. My 4 minor children and I heard what sounded like a large balloon popping inside my car. Upon further inspection, my sunroof spontaneously exploded. Absolutely nothing hit our car. The more research I’m doing, this is a known issue with GM manufactures and they have done nothing to correct this issue. 3. I’m working on getting a repair scheduled, once we figure out if it’s under warranty or we have to pay for it through insurance. 4. No warnings

The vehicle would jerk when changing gears and would have a rattle and vibration when accelerating.

The glass of the front movable sun roof shattered. The glass shattered while driving on hwy 89 in Wyoming with no traffic or no identifiable reason for the event. While some glass was saved most of it blew out when is shattered. The problem has not been reproduced or confirmed by the dealer. The dealer blames a flying rock or other object impacting the glass even though no vehicles or source of incident impact was perceived. No one was interested in taking a report. There was a build up of pressure inside the vehicle prior to the blow out of the glass which caused the drivers ear's to pop when the sun roof blew. The remaining glass was visibly pushed upwards away from the vehicle. A picture is available.

The contact owns a 2024 Chevrolet Suburban. The contact stated that while towing a trailer, the message "Trailer Brakes Disconnected" was displayed. Due to the failure, the trailer brakes locked up and the trailer came to an abrupt and rough stop. Upon investigation, the contact discovered Technical Service Bulletin: 23-NA-149; which was related to the solar panel battery charger or generator on the trailer. The trailer battery was fully charged and had a higher charge than the battery needed and could back feed into the trailer brake power module and cause it to shut down. The dealer was notified of the failure, and the contact was informed that the vehicle was not under recall. The manufacturer was also notified of the failure, and the contact was referred to the NHTSA Hotline to file a complaint. The vehicle was not repaired. The failure mileage was approximately 5,000.
