I was driving the truck on my way to work in [xxx] , last March 12, 2026, at around 6:50 am. It was raining when I entered the exit ramp to work going west; the truck died, and the steering wheel locked. I tried to start it, but it wouldn't. The dashboard displayed: 'trailer park brake failed,' 'power steering pump needs service,' and 'axle repair error. ' I was on the exit ramp for a highway that runs north and south, and I could have been t-boned; it was still dark. The truck was towed to curry Chevrolet in scarsdale. They said it was the ecm and ordered the part. They installed the new ecm module last Tuesday, March 17. The service manager called me and said they tested the truck, but it is still showing active codes. A gm advisor called me saying the truck should be ready for pickup this Friday. However, this afternoon, I got a call from the service manager saying there is another issue—the engine wiring harness—and they will order the part; now it will not be ready until next week. Gm owes me my life. I do not want to drive the vehicle. The service department people at curry Chevrolet are very professional, but did I pay and spend a lot of money for a garbage truck? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
The infotainment system has not worked since day one and the entire dash and everything electrical sometimes malfunctions or doesn't work. The vehicle has been in the shop non stop for 8 months and it has not been fixed and they have said they can't fix it. According to gm they are waiting on another part to replace but the part is on back order with no timetable to get it and the mechanic has said that part won't fix it.
Following vehicle startup, the entire audio system defaults to a muted state, affecting all sound output channels. This includes, but is not limited ?critical safety alerts: seat belt warnings, system malfunction indicators, and door ajar chimes. ?proximity and collision warnings: parking assist chimes, rear cross-traffic alert (rcta) warnings, and backup collision intervention (bci) alerts. ?communication systems: navigation prompts and hands-free/bluetooth call audio. ?the audio failure persists until manual user intervention or the next vehicle cycle, disabling critical warning redundancy. ?safety implications ?the system-wide audio failure directly compromises the safety of vehicle occupants and surrounding pedestrians in two primary ways: ?risk to pedestrians: the silencing of proximity and backup collision warnings (rcta, bci) removes a vital layer of redundancy, significantly increasing the risk of striking vulnerable road users, such as children, while maneuvering in reverse. ?impaired driver safety & compliance: the defect also removes essential alerts like seat belt warnings and renders the mandated hands-free communication system inoperable, forcing potential driver distraction or non-compliance with driving regulations. ?conclusion ?this audio muting defect is a critical safety failure that disables mandated auditory warning systems, severely limiting the driver's ability to operate the vehicle safely and respond to immediate, unseen hazards. Immediate investigation and resolution are necessary.
Have had issues since purchase of paint chipping severely / cloudy. Transmission shudder and “jumped forward” when coming to a stop. Lighting system “blinked” or went dark and come back up a few seconds later while driving.
The contact owns a 2025 Chevrolet Silverado 2500. The contact stated while her husband was hauling a trailer and driving 55 mph in the snow, the vehicle lost power steering functionality. In addition, the contact stated the vehicle failed to accelerate as intended while depressing the accelerator pedal before slamming into gear. The rpm fluctuated up to 6,500 rpm. The contact stated that the check engine warning light was illuminated. The contact's husband was able to coast to the side of the road. The vehicle was turned off but failed to restart. The contact's husband stepped out of the vehicle, and the vehicle restarted automatically. The vehicle was towed to a dealer, where it was diagnosed that the wiring was for a diesel vehicle; however, the contact's vehicle was gasoline operated. The contact was informed that the wiring harness control arm had rubbed against the control arm, causing the electrical system to short-circuit. The vehicle was repaired. The failure had progressively gotten worse. Most recently, the contact stated that the vehicle vibrated abnormally while driving. The vehicle was taken to the dealer; however, no cause for the failure was found. The contact stated that a seal was placed on the transmission. The manufacturer was made aware of the failure but denied assistance. The failure mileage was approximately 42,000.
