The electronic charge port door locked up, which completely prevents access to the charge port unless you break the panel off. This component breaking is commonly-reported and Chevrolet does NOT offer a mechanical alternative. Repairs are covered by warranty, but when the warranty expires, I presume they will not cover it anymore. In that case, litigation might be necessary.
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.
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.
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.
I have found multiple times that the Instrument Panel (IPC) display and the center Infotainment displays have gone dark while driving. This has put me in unsafe driving situations because I am unable to monitor my speed and other important information displayed on the dashboard, or to control critical safety controls such as headlights, and other ADAS safety controls. Several software updates have been installed by the dealership, but the problem has persisted, suggesting a hardware issue with the radio unit. The manufacture insist it is a software problem and that they are working on a solution. Declining to replace the radio under warranty, additionally, they want me to wait until a new update is released, and in the meantime, my bumper-to-bumper warranty is about to expire. I have found that the radio unit is the main control module for both displays, multiple ADAS controls, and Headlights, and it should be recalled, with the manufacturer extending the warranty or including the radio as a safety feature under the extended powertrain warranty.
