The contact owns a 2023 Chevrolet Colorado. The contact stated while driving approximately 5-30 MPH on several occasions, and occasionally while reversing out of a parking spot, the Forward Collision Avoidance Emergency Automatic Braking system unintendedly activated and stopped the vehicle. The contact stated that several undisclosed warning lights were illuminated. Additionally, the check engine warning light had illuminated 30-35 days after purchasing the vehicle. The vehicle was taken to a dealer to be diagnosed. The contact was informed that the front collision wiring system, the electronic control unit, and the evaporative emissions control system needed to be replaced. The contact stated that the vehicle was possibly already repaired under NHTSA Campaign Number: 24V133000 (Electrical System, Forward Collision Avoidance); however, the failure occurred. The vehicle was taken to another dealer, Grieco Chevrolet of Delray Beach (2605 S Federal Hwy, Delray Beach, FL 33483) where it was diagnosed and determined that the front collision wiring system, the electronic control unit, and the evaporative emissions control system needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 8,300.

Turn signal indicator blinks in opposite direction. When turning right and completing the turn the indicator blinks left causing confusion to other drivers who assume I’m turning left. On several occasions cars have pulled out in front of me nearly colliding. After many attempts to fix the problem the GM dealer replaced turn signal switches but the problem still persists.

After completing a right turn with a right turn signal, the vehicle will sometimes signal a left turn for 3 blinks. I believe this is because the turn signal stalk 'bounces' down to the left turn signal area when returning back to normal position from a right turn.​ ​ This is a safety issue because the vehicle is signaling a left turn when no turn is intended. This could cause confusion to other drivers on the road.​

On [XXX], I discovered that the backup camera on my 2023 Chevy Colorado was malfunctioning. Regardless of whether I was operating the vehicle in reverse or manually activating the backup camera, it remained inoperable. On the same day, I made a reservation with my local Chevrolet dealership in Elko, Nevada, to have the backup camera inspected. I took the truck to the dealership on July 19 for a repair under warranty. However, the technician informed me that the issue could not be resolved and believed it was a harness that had become pinched and required replacement. The dealership ordered the necessary part but was unable to provide an estimated time of arrival (ETA). As of December 1, despite my efforts to resolve the issue with both the dealership and GM’s corporate entity, I have yet to receive an ETA or any parts for repair. According to the National Highway Traffic Safety Administration (NHTSA), backup cameras are mandatory safety equipment for vehicles manufactured in 2018 and newer. I have brought this matter to the attention of GM and the dealership, but it appears to be unaddressed. The design of the truck makes it challenging to see behind, and the inability to perceive potential hazards in the rear poses a safety risk. GM has failed to address this issue, despite the fact that it is a critical safety feature. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Side object sensors go off frequently when no vehicles are there on both sides of vehicle. Additionally when passing vehicles the side object sensors only detect vehicles about 40% of the time. The side object sensors will double flash when no vehicles are there and fight me when changing lanes when lane assist is on. I have video of the false alerts and non detection incidents.

Speedometer and infotainment digital display. Speedometer changes from MPH to KPH, Infotainment display/Speedometer shuts down while driving. Not able to tell correct speed or see speed and critical information. Dealer said that there was no problem even after updating computer system. No other inspection has been done. No previous indications of problems, this first started 5-6 months after receiving the vehicle. This is a company vehicle that is tracked, daily I get alerts that the driver is doing speeds that are impossible due to traffic and I have had the problem replicated for me.
