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

Multiple warning lights on the vehicle stating the ABS brake system was not functioning, the letters brake showed by the gauges but it was not the parking brake because I put that on to check it and it was a different warning light. The lane assist was not functioning. In January I had the brakes looked at because they are squealing anytime you use them. The brake shop I took it to told me this is a known issue and the brakes are fine and that there was no way to stop the squealing because my brakes still had 80% of their pad. On multiple occasions when I’ve need to brake hard quickly the car had felt like it was shaking and the brakes didn’t feel like they were catching. Vehicle is currently at Vandergriff Chevrolet in Arlington Texas and has been there since August 25th.
