2025 Chevrolet Blazer

What component or system failed or malfunctioned, and is it available for inspection upon request? On September 12, 2026, while parked at the top level of a parking garage, the vehicle unexpectedly began rolling forward after being parked and exited. The vehicle subsequently struck a concrete wall. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? On September 12, 2026, my son parked the vehicle on the top level of a parking garage. He exited the vehicle while I remained seated in the rear seat and his girlfriend remained in the front passenger seat. I later moved to the driver's seat to speak with her. As I exited the vehicle to meet my son, the vehicle unexpectedly started rolling forward on its own. Nothing was touched or intentionally activated prior to the vehicle moving. Because the vehicle began moving while I was exiting, I fell and suffered injuries including a scraped knee, swelling and injury to my foot, pain in my hands, and abrasions on my arm. The vehicle continued rolling and struck a concrete wall, causing damage to the front of the vehicle. The unexpected vehicle movement placed me, the passenger, and other nearby individuals at risk of serious injury. Has the problem been reproduced or confirmed by a dealer or independent service center? I am reporting these incidents for investigation. The vehicle is available for inspection by Chevrolet, the dealer, NHTSA investigators, insurance representatives, or other authorized parties. No warning lamps, messages, or other alerts were observed prior to the Rear Automatic Braking events or the vehicle roll-away incident. The braking events and vehicle movement occurred unexpectedly and without warning. I no longer feel safe operating this vehicle. Between the multiple false activations of the Rear Automatic Braking system and the incident on September 12, 2026, where the vehicle unexpectedly rolled forward and caused injury

I am concerned about a significant safety issue with my 2025 Chevrolet Blazer EV. On at least four separate occasions, the vehicle has unexpectedly applied extremely hard Rear Automatic Braking while I was backing up, despite there being no object, vehicle, person, or obstacle behind the vehicle. The braking is so abrupt and forceful that it feels as though the vehicle has collided with something. Because the driver is typically looking over their shoulder while reversing, the sudden stop causes a violent jolt. This has resulted in neck pain and headaches for me and my son on multiple occasions. One of these incidents also occurred while my son was driving the vehicle. We discussed the event afterward and both experienced the same sudden, aggressive braking with nothing present behind the vehicle. The system appears to be activating falsely. This is a serious safety concern. The unexpected braking could potentially cause injury to the driver or passengers and may also create a hazardous situation if another vehicle is following behind. I am requesting that this issue be investigated and repaired as soon as possible.

windshield leaking water inside of drivers compartment, headliner & side pillars (causing stained areas) as well as the top of onstar and electrical buttons on the overhead console . Found wet cup holder. Vehicle does not have a sun roof. GM is aware of this issue from the factory GM plant in Ramos Arizpe, Mexico. This defect is because of lack of not being sealed properly during the assembly process. The windshield has a factory OEM rubber seal attached to a NEW windshield. This rubber seal is NOT a part that can be purchased separately to fix the problem. By replacing the entire windshield with the new factory rubber seal and the channel that the entire windshield fits into is resealed with urethane should fix the issue.. Trying to reuse the current windshield & rubber seal and using sealer to reinstall it stretches out the rubber seal & will still leak. This leak can get into the electrical controls for safety system overhead controls. Extra care must be taken to remove the windshield as to not damage the roof line in anyway. Vehicle is going back into dealership to fix issue again. Vehicle was resealed with existing windshield and showing signs of leaking on L&R pillars.

2025 Chevrolet Blazer EV AWD purchased 5/23/25 (under 3,100 miles) The vehicle's Telematics Control Module (TCM) has failed, disabling the built-in navigation system, OnStar services, remote start, and My Chevrolet app connectivity. The dealership confirmed the TCM needs replacement and the part is on backorder with no ETA. This is a known issue affecting this model. I am reporting this as a safety defect for the following reasons: The 2025 Blazer EV does not support Apple CarPlay or Android Auto. With the built-in navigation disabled, the only way to navigate is by using a phone, which requires visual attention to a separate small screen while driving. Under Pennsylvania's hands-free law (75 Pa.C.S.A. § 3316.1), use of handheld devices while driving is a primary offense, making phone-based navigation both unsafe and legally problematic. On at least one occasion, the navigation system appeared to be functioning normally at the start of a trip but was providing materially inaccurate directions mid-route (e.g., instructing me to turn onto a road I had already been traveling on for miles). A system that displays as operational while delivering incorrect routing data is dangerous because the driver has no way to assess its reliability before departing. GM's EV Concierge characterized the loss of navigation as a non-safety feature issue and suggested using a phone holder. This response is inadequate given the vehicle's lack of CarPlay integration, which makes the built-in navigation the only safe, integrated means of route guidance. This vehicle has also required three prior unrelated warranty repairs in 10 months: a recall for a faulty rear parking brake harness (9/25), a 12V battery failure requiring flatbed towing (11/25), and a faulty tire pressure monitor (12/25). The pattern of recurring failures across unrelated systems at minimal mileage indicates a systemic quality issue with this vehicle.
