I am reporting a recurring safety issue with the Forward Collision Alert/Automatic Emergency Braking system on my 2023 Chevrolet Blazer 2LT. The vehicle frequently activates the Forward Collision Alert when there is no vehicle, pedestrian, or other obstruction in front of me. The red collision warning will illuminate and the system will beep even when the roadway is clear. More concerning, on three separate occasions the vehicle has unexpectedly applied the brakes extremely hard while I was driving in traffic despite there being no obstacle or imminent collision. The most recent incident occurred on August 11, 2026. I was making a turn through a busy intersection when the Automatic Emergency Braking system suddenly activated and applied the brakes extremely hard. There was no vehicle, pedestrian, or obstruction in my path that would have required emergency braking. The sudden braking occurred while I was in the intersection and created a serious risk of being struck by surrounding traffic. The braking force was severe enough that my seat belt restrained me very hard and caused an injury to my chest and flew me forward into the steering wheel while also risking the vehicle behind me to almost slam into me. This was not an isolated occurrence. This is the third time the vehicle has unexpectedly applied the brakes hard while I was driving in traffic. In addition to these three braking incidents, I have experienced frequent false Forward Collision Alerts where the red warning and audible alert activate when nothing is in front of the vehicle. I am concerned that the Forward Collision Alert/Automatic Emergency Braking system is malfunctioning and could cause a collision by unexpectedly stopping the vehicle in moving traffic. I am requesting that this recurring safety issue be documented and investigated.
The vehicle’s radiator developed a coolant leak that was discovered and confirmed by the dealership during a routine oil change, tire rotation and state inspection. There were no warning lights, warning messages prior to the dealership discovering the leak. The radiator required replacement. The dealership also told me that they had the replacement radiator on hand because this type of radiator failure had been occurring fairly often with this type of vehicle. The radiator failure presented a potential safety concern because a coolant leak can worsen without warning and result in a sudden loss of coolant, engine overheating, or vehicle breakdown while driving. Because there were no warning lamps or other symptoms before the leak was discovered, we may not have had any indication that the cooling system was failing. The problem was confirmed by the dealership during inspection, and the dealership determined that the radiator was leaking and needed to be replaced. The vehicle/component was inspected by the dealership. No manufacturer, police, or insurance inspection has occurred, to my knowledge. There were no warning lamps, messages, overheating, or other noticeable symptoms prior to the dealership finding the leak. The vehicle is only three years old, with 39000 miles on it at the time of the failure. I am reporting this because a radiator failure at such a young vehicle age, particularly one that develops without any warning to the driver, could potentially create a safety hazard if the coolant loss becomes severe while the vehicle is being operated. I’ve seen many complaints in online forums that this is an ongoing issue with these radiators used by Chevy. It seems the replacement radiators are having the same issues. Why can’t something be done? Dealership information: #1 Cochran Chevrolet Cranberry [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

"I am the owner of a 2023 Chevrolet Blazer RS. The digital odometer and speedometer screen intermittently crashes and goes completely black for 15 to 20 seconds while the vehicle is in motion on public roads. This creates an immediate safety hazard as I am left with zero knowledge of my current speed. General Motors has acknowledged this specific software stability bug under Technical Service Bulletin 22-NA-023 but refuses to fix the issue due to the vehicle being 9 days past its 3-year calendar warranty, despite having only 32,400 miles." I contacted your GM agent @ 800-222-1020 and was told its out of warranty sorry, that is horrible service espeacially for a safety issue and a 55,000 vechicle that only has 32,400 miles
