This vehicle experiences multiple recurring safety-critical system failures while driving, creating a dangerous operating condition for both the driver and the public. 1. Dashboard / Instrument Cluster Failure While Driving While the vehicle is in motion, the dashboard display intermittently shuts off completely. When this occurs, I cannot see my speed, warning lights, battery status, or any other gauges. This creates a severe safety risk because I am effectively driving without any instrument information. The issue occurs while actively operating the vehicle on public roads. 2. Navigation / GPS Location Failure The vehicle’s built-in mapping system frequently shows my location several states away from my actual position. Even though the location is incorrect, the system continues to provide turn-by-turn navigation instructions based on the incorrect location. If these directions were followed, it could cause a driver to make unsafe maneuvers or become distracted while attempting to correct the navigation error. 3. False Automatic Emergency Braking Activation The automatic braking system frequently activates even when there are no vehicles, pedestrians, or obstacles present. The vehicle abruptly slows or brakes on open roads with nothing nearby. This creates a significant safety hazard because it could cause a rear-end collision if another vehicle is following. Repair History / Ongoing Issue: This vehicle has been taken in for repair multiple times for these issues. Despite attempted repairs, the problems continue to occur. The recurring nature of these failures indicates a systemic defect that has not been corrected. Safety Concern: These failures create multiple hazardous driving conditions: Loss of dashboard information while driving Incorrect navigation location and directions Unintended automatic braking events Allowing this vehicle to remain in service with these unresolved defects places both the driver and the public at risk. Request: I am requesti

Left turn signal can activate by itself after right turn. Details: Driving and making a right turn with the right turn signal active, after the turn when the signal cancels, the signal sometimes activates the left blink-to-pass feature causing the left signal to blink 3 times. This appears to be because the turn signal arm falls too hard. When turning onto a multi lane road this causes confusion to drivers coming up behind where they think I am moving into the left lane, but I am not. GM has loaded software to reduce this but it still happens. They replaced my turn signal arm and it still happens (much less often now). I can prevent it from happening by using my finger to dampen the turn signal arm when it cancels by catching it and slowing it down. I stopped using my turn signal completely as it is embarrassing when it does this.

The glare reflecting from the dashboard on to the windshield is many times blinding and obstructs a lot of the front view. Also randomly the side mirrors tilt up while driving giving me a view of the sky but not the road behind me.

While driving the vehicle loses power to the instrument panel and gauges and infotainment system. The vehicle remains under power however the driver looses the ability to see how fast the vehicle is moving or any information as the entire dashboard loses power. The safety to both myself and my family as well as other drivers is at risk if I am unable to see how fast I am going or control any equipment in my vehicle. This is a known issue online with many other drivers of the blazer EV experiencing the same issue with no remedy from the manufacturer.

After getting the recall repaired (which I was never informed of and I had the parking brake engage as I was travelling 30 mph causing me to skid down the road) I got the vehicle back and the very next day it was the same issue and the abs and traction control light came on and it began making loud clicking noises every time I would engage the brake.

The right side tail signal light module needs to be replaced. I was having intermittent issues with the right turn signal, I took the car to the dealership and they told me that the module needed to be replaced. The car has been in the dealership since March 19th, more than a month ago waiting for the part. I contacted Chevrolet and they keep telling me that no ETA for part is available, and they do not provide any more details on what is causing this delay.

This vehicle with a total of 700 miles on the odometer, gave several warning notifications this morning on my way to work. Service high voltage system, reduced acceleration notification. I was on the interstate and suddenly became unable to accelerate to keep up with traffic, creating a dangerous situation for my safety. This is a know problem with the Blazer EV, as GM had previously issued a stop sale order in December of 2023, a supposed software update was issued and they continue to sell the dangerous vehicles, as the software update did not fix the problem as I just experienced it today, on a car I bought brand new 2 weeks ago with 700 miles on the odometer.

The emergency brakes engaging in reverse and while in drive. Not available for inspection as the vehicle is now totaled. It was involved in a rollover accident. I believe the emergency brakes caused the rollover. If the rollover was in fact due to the emergency brakes engaging, the accident could have happened on the highway, or a busier street putting several lives in danger. Thankfully, there were no other vehicles involved. The dealership as well as GM were notified of the issue. The dealership was unable to reproduce the issue, and returned the vehicle backed to us. Upon researching online, this is a known issue for the Blazer EVs. After the accident, the vehicle was towed as it was not drivable. The vehicle was then picked up by my insurance company, Progressive, and evaluated if the vehicle was repairable. It is not. The emergency brakes engaged previously to this event. Several times in reverse, then a handful of times in drive.
