Driver assistance reportsComplaints are reports submitted to NHTSA by owners and drivers.

The front camera lens cover — located in the grille below the Chevy bowtie logo — has developed a spiderwebbed/shattered crack pattern. There is no impact damage to the surrounding grille or bodywork. The vehicle was garaged and not in use when the damage was discovered. The camera appears to still be working and parts of the image are crystal clear but the cracks in the cover distort the picture and make it impossible to use reliably. This is consistent with a material defect, not road damage. I have opened a case with GM Customer Care regarding this defect. My case number is: XXX.

Contining with issue referenced in 11701484. This morning (1/28/26) when leaving my home, I backed out of my driveway. Once I put the car into drive, the forward collision warning went off and locked up my car. The brakes would not release and I could not move out of the way of oncoming traffic. I do not know what allowed the brakes to finally release. I changed over to 4x4, put it into park and back to drive. My car finally was then allowed to move.

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.

I was driving down the highway at 70mph using the adaptive cruise control. There was nobody in front of me, and suddenly the vehicle started picking up speed. I looked at the cruise control and it said 115mph, so I hit the brakes to override it and slow down. when I reset it for , ~70mph again it worked fine. This happened to me two other times with the same basic scenario. The speed is always over 100mph, and it always occurs when the adaptive cruise control has been in use for at least 30 minutes. I have an appt with the dealer that I bought it from to have it looked at. No warning lights and no other symptoms.

On the evening of [XXX], I was making a left hand turn onto [XXX] from [XXX]. I was the second car in line on the left turn green arrow. The first car went to the right lane. I went into the left lane. My car immediately flashed the light in the front window, the alarm went off, and slammed the brakes as if something was in front of me. Nothing was in front of my car in the left lane. Luckily there wasn't a car on my rear bumper otherwise I would have been rear-ended. This is the 2nd time at the same intersection making the same turn that my Blazer has done that. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
