"I am the owner of a 2023 Chevrolet Blazer RS. The digital odometer and speedometer screen intermittently crashes and goes completely black for 15 to 20 seconds while the vehicle is in motion on public roads. This creates an immediate safety hazard as I am left with zero knowledge of my current speed. General Motors has acknowledged this specific software stability bug under Technical Service Bulletin 22-NA-023 but refuses to fix the issue due to the vehicle being 9 days past its 3-year calendar warranty, despite having only 32,400 miles." I contacted your GM agent @ 800-222-1020 and was told its out of warranty sorry, that is horrible service espeacially for a safety issue and a 55,000 vechicle that only has 32,400 miles

Re: Vehicle Safety Defect Complaint – 2023 Chevrolet Blazer To Whom It May Concern, I am submitting a formal safety defect complaint regarding my 2023 Chevrolet Blazer. This vehicle has exhibited multiple system failures that present a serious risk to driver safety and public roadway safety. The vehicle was purchased new on July 20, 2023. Beginning on April 21, 2025, at approximately 27,610 miles, the vehicle developed a progressive defect initially presenting as oil-related issues. Despite multiple repair attempts, the condition worsened and required a full engine replacement in January 2026. Following the engine replacement, the vehicle continued to experience critical safety failures, including engine stalling, reduced engine power warnings, and electronic stability control (ESC) alerts. On April 26, 2026, the vehicle experienced a driver assistance system malfunction in which it attempted to steer off the roadway. I was forced to manually disable the system to maintain control of the vehicle. On April 27, 2026, the vehicle exhibited a fuel system failure, including fuel leakage and fuel odor, along with multiple simultaneous warning indicators: • Reduced Engine Power • Service ESC • Steering Assist Reduced / Drive with Care • Power assist driver system disabled This combination of failures presents both a fire hazard and a loss-of-control risk. Additionally, I was informed by the dealership that a high-pressure fuel line, a one-time-use component, was not replaced during the engine installation. This raises concerns regarding improper repair and continued unsafe operation of the vehicle. The vehicle has undergone multiple repair attempts and a major powertrain replacement, yet continues to present serious safety concerns. Due to these ongoing issues, I do not feel safe operating this vehicle. I respectfully request that NHTSA review this matter for potential safety defects that may impact other vehicles of the same make and model.
STEERING,UNKNOWN OR OTHER04/18/2026
My vehicle makes a clunk noise when the vehicle is in motion and i press on the accelerator it also makes a little jerk. This mainly happens @ low speeds and on a incline hill. There some type of oil or grease stains where the cv axle goes into transmission. ive felt my vehicle with less power and pulls to the left. Took the vehicle to chevrolet and they said they couldnt duplicate the issue or the oil leak.

ENGINE02/27/2026
The radiator developed a leak at around 36k miles and needed to be replaced. My understanding is that this is an ongoing problem with this vehicle.
ELECTRICAL SYSTEM,EXTERIOR LIGHTING02/05/2026
My bright lights do not go off when oncoming vehicles or vehicles in front of me are close and when they do dim they go on and off. People flash their brights at me causing me not to be able to sleep and this happens even when they turned off of auto. Another item of concern is that the car would lock and unlock and the interior lights would go on and off. This was fixed but it was a line under the front that was not soldered together at the manufacturer is what the Chevy dealership stated.
