2006 Chevrolet Silverado 3500

Since repair work was performed on this vehicle in late 2025, it has intermittently experienced sudden, complete brake lockup on all four wheels without any pedal input. This has occurred during sharp turns and during straight, steady highway driving, both suddenly and after gradual buildup; regardless of the pattern leading up to it, the lockup itself is abrupt and unexpected. On March 25, 2026, driving approximately 70 mph on the Glendale Freeway (SR-2) between Mountain Ave and Foothill Blvd, at approximately 39,900 miles, all four brakes suddenly applied with no pedal input, causing the truck to skid toward a stop while traffic continued to pass at highway speed. Smoke was visible from the front wheels and in my mirrors. No crash, fire, injury, or fatality occurred, but the vehicle poses an ongoing risk of sudden, uncommanded loss of control, especially hazardous at highway speed with surrounding traffic. The dealership's inspection found blue thermal discoloration on all four brake rotors, consistent with extreme, sustained overheating, and recommended full brake system replacement estimated at $23,875.25. I am retired, on a fixed income, and cannot readily absorb a repair of this magnitude for an intermittent but serious safety defect. This vehicle uses a Hydro-Boost brake system. GM has published service information (Bulletin PIT3665J) describing a known condition on this platform where the brake pedal can move or self-apply, caused by the internal dump valve failing to seat due to steering system contamination. This bulletin covers Chevrolet Silverado and GMC Sierra trucks across model years 1998-2020, among other GM platforms. Given the severity of this failure and the number of vehicles affected across more than two decades, I believe this warrants review as a potential safety defect.

on 7SEP 2025 @ 1100 While backing out of my driveway in my 2007 Chevy 3500, the vehicle’s airbag suddenly and unexpectedly deployed without any collision. The airbag struck me in the chest and left forearm, causing immediate injury. Since the incident, I have been experiencing chest pain and shortness of breath. Prior to this incident, I had taken my truck in for service due to concerns about the airbag recall affecting certain GM vehicles. At that time, I was informed by the dealership that my truck was not included in the recall year range. Despite this, the airbag has now malfunctioned in a way that has caused me injury. I attempted to contact the National Highway Traffic Safety Administration (NHTSA) and the GM/Chevy Safety Office to report the matter, but both offices were closed at the time.

The contact owns a 2006 Chevrolet Silverado 3500. The contact stated that while driving at a low rate of speed, the contact heard an abnormal, thud-like noise emitted from the vehicle. The contact pulled into an independent tire shop and inspected the tires. The contact found no defect with the tires and chose to proceed with driving the vehicle. While driving at approximately 40 mph, the front passenger-side tire detached from the vehicle without warning. Due to the failure, the vehicle crashed into a ditch. The air bags did not deploy. A police report was not filed. The vehicle was towed to an independent mechanic, and the contact sought medical attention for pain in her back. The contact was diagnosed with a sprain to the right side of her neck and right side of her back. The vehicle was then towed to a different independent mechanic, where they determined that the wheel assembly hub had detached from the vehicle. Upon investigation, the contact discovered NHTSA Campaign Number: 07E106000(Wheels) and linked the failure to the recall. The manufacturer was informed about the failure. The vehicle was not repaired but remained in the possession of the independent mechanic. The failure mileage was unknown.

DURING A TRIP WITH 6 MONTH OLD TIRES, TWO OUT OF 6 TIRES FAILED. ONE WAS A DEEMED A ROAD HAZARD BY THE MANUFACTURER. GIVEN THESE TIRES WERE PURCHASED AND INSTALLED ON A TOW VEHICLE WITH RATINGS FOR THE VEHICLE AND FAILED ON A 75 DEGREE DAY WITH A LIGHT MIST. I WOULD SUSPECT THAT THE TIRES ARE NOT CAPABLE OF MEETING THE RATED SPECS. THE TIRES WERE PURCHASED JANUARY FROM TREADWRIGHT CORP.
