Forward collision avoidance

35 reports4 crashes
“This morning, I stopped to open the gates at work, car was idling. When I got back into the car, put it in drive and started to slowly move forward the FORWARD COLLISION SYSTEM slammed on my brakes and lights flashing on my dash. I backed up...there was absolutely nothing in my way. This has happened numerous times, different places and while turning a corner at a very slow speed. Never nothing in the way. Will definitely be taking it in to have it checked now.”

Service brakes

30 reports6 crashes
“Auto hold was on, radar cruise control was set and as I was merging in traffic a sharp smell of burning started. The cruise control refused to disengage until I parked the car in garage. Eventually burn smell ended but seems like brake was stuck while acceleration causing a burn smell. It seems like brake could get stuck to wheels perhaps when auto hold is on even when driving? Auto break hold is a feature which keeps the break on while car is stopped.”

Fuel/propulsion system

12 reports
“My 2024 Chevrolet Blazer EV AWD has experienced two separate incidents involving sudden loss of propulsion without warning. First Incident – XXX While driving in [XXX], the vehicle suddenly lost propulsion without warning while I was in a turn lane in front of a medical center. Following the loss of propulsion, the Driver Information Center displayed warnings associated with the AWD system, shift system, and high-voltage system. The vehicle could not be driven or shifted and became disabled in the roadway, creating a potentially hazardous traffic situation. An expedited tow was required because of the location of the disabled vehicle. The vehicle was taken to a Chevrolet dealership in Novi, Michigan. I picked it up on XXX. I was informed that a vehicle-wide reprogramming had been performed, the vehicle had been updated with the latest available software, and the condition should be resolved. Second Incident –XXX Only 12 days after the vehicle was returned following the reprogramming, the vehicle experienced another sudden loss of propulsion without warning while my cousin was driving on [XXX]. Following this event, warnings were displayed indicating that the…”

Power train

11 reports
“Vehicle: 2024 Chevrolet Blazer VIN: [XXX] Component: Engine Cooling System (Radiator) Description of Incident: On XXX the vehicle was brought in for a routine maintenance service at approximately 20,000 miles. During the inspection, technicians at Hamilton Chevrolet in Warren, Michigan discovered a premature radiator leak. The servicing technician noted that this is a common failure on modern Blazers due to a manufacturing material mismatch, specifically where the plastic end tanks meet the aluminum radiator core. This structural component failure poses a severe safety risk. A rapid loss of engine coolant can cause immediate engine overheating, thermal management failure, and a sudden loss of vehicle propulsion while driving at highway speeds, significantly increasing the risk of a crash. Corrective Action: The defect was located and the radiator was subsequently replaced under the factory warranty by Hamilton Chevrolet (Warren, MI). However, this failure occurred far too early in the vehicle's lifecycle, indicating a structural or material defect in the OEM radiator seams. Please investigate this issue, as premature cooling system failures on this model year…”

Visibility/wiper

11 reports
“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.”
