Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have had my cruise control set and my car will slam on the brakes with no vehicles in front of my car or on each side. This has happened multiple times, it doesn’t matter if I am going 40MPH or 60+MPH. I have taken it in and they say there is nothing they can do for the issue. I’m worried for the safety of myself, my family, and my unborn child. As well as any cars around (behind me potentially) when this happens. I do not want to unintentionally cause an accident.”
NHTSA complaint #11665912, filed 2025-06“The engine light comes on and then the rpm's drop to 35 and a notification comes up that says reduced acceleration. driving with caution . If I stop and turn of the vehicle and restart the rpm's will be better but the truck still seems to have a difficult time increasing in rpm's and accelerating gears. It's incredibly dangerous as if I'm driving at a substantial speed on the highway or freeway and it drops rmp's rapidly I'm likely to be in an accident which could be detrimental. The dealer has had my vehicle on two separate occassions. …”
NHTSA complaint #11681402, filed 2025-08“The check engine light came on at 14k miles indicating there was an emissions error. The brakes squeal and have had to be replaced 3 times since the original purchase in March of 2024. After the third replacement of brakes they still squeal. Even if the car is not braking it makes the noise. The radio shuts on and off constantly. Chevy reported they are aware of the issue but there is no fix at this time. The dealerships reset the radio but the issue persists. I’ve had to park the car because I’m afraid the brake issue is much more than they’re willing to admit.”
NHTSA complaint #11645479, filed 2025-02“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. …”
NHTSA complaint #11728081, filed 2026-03, 5,000 miles“Persistent, intermittent total audio cutout disabling critical crash avoidance alerts. Failure Summary & Safety Impact: The vehicle experiences intermittent, complete failures of the audio system across all sources. When this failure occurs, all audible safety warning chimes are completely silenced—including Forward Collision Alert, Front Pedestrian Braking, Lane Departure Warning, and Park Assist.
