2025 Chevrolet Silverado 1500 electrical problems

Filed Nov 5, 2026 · Electrical · AZ

The vehicle experiences intermittent 1-to-2-second total audio dropouts across all stereo sources, including the turn signals, radio and Apple CarPlay. Because the vehicle generates and routes audible safety alerts through the infotainment module and audio amplifier, the audible turn signal indicator (blinker clicking sound) and critical driver safety chimes (forward collision alert, backup park assist, and seatbelt warnings) fail to sound during these cutouts. The infotainment system is already running software build W231E-Y181.3.2-SIHM22B-499.3 231 release-keys, and the intermittent loss of turn signal and safety chimes persists. Per GM Bulletin PIT6406, dealerships are instructed not to replace the radio or amplifier while GM Engineering investigates, leaving the vehicle with an unresolved intermittent failure of audible safety indicators.

The specific cause has not been identified. On XXX6, my 2025 Chevrolet Silverado 1500 Custom LT Trail Boss unexpectedly rolled away while parked and unoccupied, striking another parked vehicle. The truck remains at Modern Chevrolet and is available for inspection. GM/ESIS opened a safety and product liability investigation and is arranging inspection/data retrieval. I parked at Walmart in [XXX], shut the truck off, exited, locked it, and walked away. Shortly afterward, I heard a sound resembling the key-fob-left-inside warning. My key fob was in my pocket, so I returned and saw the truck moving with no driver. Another person and I tried to stop it. I entered through the driver’s door and pressed Start/Stop several times, but it would not start while moving. It continued moving and struck another parked vehicle. Vehicle dropped off on XXX and Modern Chevrolet could not reproduce the incident or identify the cause. The service advisor stated it “came out of gear but don’t know why” and escalated it to GM. GM/ESIS plans to retrieve SDM/airbag data, and I requested any Tech II/MDI scan data. No warning lights, messages, or chimes were observed during the incident. I did not see/hear “SHIFT TO PARK,” and I was able to lock the truck with the key fob outside. In a later controlled test, I left the truck in Drive and shut it off. It displayed “SHIFT TO PARK” and sounded a warning chime. Opening the driver’s door also produced a key-fob-left-inside-type alert, which did not occur on XXX. The truck did not automatically shift to Park or engage the electronic parking brake and slight movement was felt during the test. No further testing occurred by me after XXX. I have also experienced infotainment freezing after software updates and random electronic parking brake application when shutting off, and remains engaged after restart. The truck received an oil change/tire rotation at Modern Chevrolet on XXX. Cause still remains UNKNOWN. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On Thursday, July 9, 2026, at approximately 2:30 p.m., I was driving my 2025 Chevrolet Silverado 1500 Duramax on Highway 40 while towing a properly connected trailer. The Multi-Flex tailgate had been fully closed and latched before I began my trip and had not been opened at any point prior to the incident. While traveling on the highway, a California Highway Patrol officer pulled alongside my vehicle and alerted me that my tailgate was down and bouncing on the trailer I was towing. I immediately pulled over to the shoulder and observed that the entire Multi-Flex tailgate had unexpectedly unlatched and was resting on the trailer. I closed and latched the tailgate, which appeared to operate normally, and continued to my destination. At no time before or during the incident did the vehicle display a "Tailgate Open" warning or any other warning message on the instrument cluster. The unexpected opening of the tailgate caused it to strike the trailer, resulting in damage to the Multi-Flex tailgate, the rear bumper, and the trailer. The vehicle has approximately 11,000 miles, was purchased new, and has not been modified. I have opened a case with General Motors, and the vehicle is scheduled to be inspected by an authorized Chevrolet dealership.

1st incident My son was driving the truck when all the emergency lights came on. He pulled over and the engine was on fire. He ran to a strangers house to get buckets of water not safe for my child at all. Come to find out that an engine rod slipped and put three holes through the engine causing oil to spill and a fire unbelievable! Lucky my son wasn’t injured. Chevy blames my son for that! Not acceptable! 2nd incident 1 month later my son calls and tells me when he started the truck it began making noise. He again got stuck with this truck because it lost complete power. Come to find out the transmission went. Chevy blamed my son again! Really come on! We have paid more for this truck than drive it. Now they are taking the warranty away. Please help.

My vehicle frequently loses all cabin sound, including the radio, audible turn signal, and forward/rear collision and lane departure warnings. When this occurs, the cabin is completely silent. The loss of radio audio is an inconvenience, but the loss of safety feature alerts is a clear hazard. My dealership has suggested this may be related to a recent software update; however, there is no apparent correlation between the updates and when the issue occurs.
