2024 Chevrolet Blazer electrical system problems

“I entered my vehicle started like normal was heading home when I got in the highway while gaining speed to get on the highway I hit about 60-65mph when my entire car went black my odometer screen went black my entertainment system went black all lights shut off and my car was just rolling I immediately tried to get off the highway and take a video when I got off the roadway everything came back on”

“The Charging Port Door and assembly broke during a public charging station while on vacation. I had to manually pull it down which stripped the plastic gears. The door had been previously aligned because it was not flush with the body under warranty. This overcomplicated mechnical, electrical door is a subject of numerous complaints on blogs. It can be stuck causing the inability to charge the EV, leaving people stranded. Before I took it to the dealer it was hanging off the side of the vehicle which causes a safety issue and could be torn off at a car wash getting water into the high voltage electrical socket. This occured while on vacation under the 36K bumper to bumper warranty but couldn't get it into the dealer until 36.5 miles and I face a repair bill of $674.77 for something that is poorly designed with numerous failures and had been already addressed under warranty.”

“The contact owns a 2024 Chevrolet Blazer. The contact stated that while driving 20 MPH with 100 miles of charge, the vehicle stalled and shut off. The screen was black, unresponsive, and failed to start. The vehicle was towed to the local dealer, where it was diagnosed with a power module failure. The part was on back order. The electric module was previously replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was 10,381.”

“Driver Information Centre (DIC) and Infotainment go dark. This has happened twice now over the last 2 months. While driving suddenly the infotainment goes blank and loses the radio and then the DIC follows by going blank (dark). So I was left with no speed indication. The car drives normally during that time. After 30 seconds to a minute the screens come back on as if it rebooted while driving.”

“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…”

“On February 4, 2026, my wife drove to the bank, a trip of about 10 to 15 minutes, and turned off the car at the ATM. When she tried to leave, the vehicle wouldn't start. After a while, she opened and closed the door and locked and unlocked the car twice with the remote control, and the vehicle started and she was able to drive, but all the warning lights on the dashboard remained on. It is currently at a Chevrolet dealership for diagnosis.”
