2023 Chevrolet Blazer

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.

I purchased this car in May 2023.Since day 1 one the car stalls after filling and out of nowhere. Can be sitting still or going down the highway and highway sped. I took it on snd they could not find anything. Was told to keep track of when it happens. After almost being rear ended several tons and being put in extreme safety I called them and took it back in . They have now had since 9/21/2023 saying they’re some kid of valve problem in the gas tank. So I am paying for a brand new car that is unsafe to drive and is at the dealer for who knows how long .
