2025 Chevrolet Silverado Electrical System Problems

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.

2025 Chevrolet Silverado Crew Cab, VIN [XXX] , purchased new in April 2025. Total transaction value exceeded $50,000 including trade in of previous vehicle. Has experienced repeated serious electrical failures in under a year and 16,500 miles. Components that failed: Telematics module causing parasitic battery drain, DC/DC converter module, radio, and two complete battery failures. Turn signal was also triggering the high beams to flash, a separate electrical issue repaired under warranty. All components are available for inspection upon request. Safety risk: First battery failure occurred in January at 10,000 miles while traveling in the desert with my wife and infant son. We were stranded with no Chevrolet dealer accessible. Second battery failure occurred at 16,500 miles. A failed DC/DC converter module was discovered immediately after the latest round of repairs when the dashboard lit up with multiple warning lights and a check engine light the same day I picked up the vehicle. I drive this truck daily for work and transport my young child in it regularly. Repeated unexpected failures create a serious and ongoing safety risk. Confirmed by dealer: Yes. George Chevrolet confirmed and attempted repairs on the telematics module, DC/DC converter module, and radio. All failures documented on official repair orders. Warning lamps: Yes. Multiple warning lights and check engine light appeared immediately upon pickup after the most recent repairs. Manufacturer response: General Motors denied my repurchase request despite multiple confirmed warranty failures and has not offered a replacement vehicle.

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.

Driving 30 mph down a city street when heard a pop and vehicle completely lost power at speed. Engine turned off and I coasted to a stop, which was unfortunately at an intersection and due to traffic could not get over safely. All accessories were still on however I could not restart the vehicle or put the vehicle into neutral, which left me stranded in the middle of a busy intersection. Hazards were working intermittently, at best. Had to call local PD to provide traffic control while we disconnected the battery and reconnected it while standing in an intersection. After I was able to get the vehicle restarted it had a check engine light and the OnStar app showed Transmission, Ignition, and Engine Electrical warnings. Had the vehicle towed to the dealership, where they have had it for 7 days and cannot diagnose an issue and are trying to return the vehicle to me unfixed. They stated they typically would not even try to diagnose it for this long, however I have a case open with the GM executive team.

While driving to work on [XXX] in Huntsville AL at approximately 55MPH. I was using Chevrolet SuperCruise. I tried turning off super cruise with the super cruise button. It did not turn off, tried pressing cruise control button, nothing, tried the cancel button, nothing, pressed brakes and would not turn off. Truck started slowing in very heavy traffic, it turned hazards on. I was finally able to get it turned off. I have reported to dealer, no surprise they didn't answer, left message at 9 am this morning, no call back. I have made a report to GM. I no longer feel safe putting my family in this truck. This truck has been in shop several times for "Service driver assist", no on-star, no cellular data, extremely slow infotainment system and no supercruise available. The truck at last visit for the service driver assist took more than 2 week. I was told a camera and a software update were performed. The issues have persisted. The super cruise event yesterday was the first occurrence of this type. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle’s wireless Apple CarPlay system forces the iPhone to connect to the truck’s built-in Wi-Fi network, which does not provide internet access. When connected, iPhone cellular data is blocked, resulting in frequent loss of navigation, traffic updates, and streaming services while driving. There is no option in the vehicle settings to disable the Wi-Fi or force cellular use. Multiple troubleshooting steps have been attempted, including iPhone network resets, Wi-Fi assist, toggling data settings, and re-pairing CarPlay, all without success. This design flaw creates a safety concern because navigation and real-time traffic information can fail unexpectedly, requiring driver distraction to troubleshoot or rely on a handheld device. The issue appears to be a firmware or design limitation of the infotainment system, not a defect with the phone. Using wired CarPlay resolves the issue, but wireless CarPlay as advertised consistently blocks cellular data. I am filing this complaint to report a persistent connectivity and safety problem that affects all users of wireless CarPlay on this vehicle model. The inability to access real-time navigation and traffic data while driving is a clear distraction and could contribute to unsafe driving conditions.

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. Thank you [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

engine failure

At random times when you start the vehicle there is no sound. No sound from the turn signals, radio, emergency flashers. Apple Car Play. You have to restart the vehicle to have it reset. You always do not know there is no sound until you have started to drive and go to use the radio of notice that the turn signal is not working. I did not realize that my left hand turn signal did not turn off and at a traffic light I was going straight and a car turn in front of me because they assumed I was making a left hand turn. There was not an accident because they were able to stop. I have had it back to the dealership a number of times. They reset the system. Said it needed a global reset. Even after the reset it still is doing this. Happens more in cold weather. I have recording that are date showing no sound. I have multiple videos but I am unable to upload due to size. I was able to share them with the service technician at Gentilini Cherolet. 500 John S. Penn Blvd. Woodbine, NJ 08270. Phone Number 609-459-0014.

The vehicle was a service loaner provided to me but it was factory new with the sticker still on the window. The dealer told me they would still sell the vehicle as new. When I started it, I had a display screen that indicated it was in a Demo mode. Taking it out of Demo mode would have required me to confirm that I had purchased the vehicle. The volume control and power control for the audio were not working at all. The volume was probably at 30% where I could hear but not clearly and also just loud enough that I couldn't hear sounds outside the vehicle well. This condition was not affected by the audio source. I could no change the volume in Bluetooth, AM, FM, XM, or Phone modes. I also could not turn off or mute the audio by pressing the Power button. There was a responding fire truck behind me on the road and I went to turn off the audio to hear it clearly and I was not able to. I took a video of this condition happening multiple times as photographs don't help to demonstrate much. I did notify the dealer by sending the Service Manager a text message with the video and said he would notate the condition. This persisted through multiple days and multiple restarts. After approx. 4-5 days, the expected functionality returned with no action or updates that I am aware of.

Driving on road at approximately 30 mph. All lights on dash came on and car braked suddenly immediately stopping the vehicle in the middle of traffic. Could not release the brake. Car was idling very rough during this time. Turned car off and back on. Brake released but still running very rough. Made it the short trip home. Truck to dealership via wrecker. Brake was again a problem getting on and off the wrecker

Days after purchasing the vehicle brand new back in 2023, it began having issues with what they thought was the new 4 cylinder mode working itself in or electrical shifting needed to be replaced… After numerous years of being stalled out on highways, unnecessary repairs made, lose of business revenue, and more. It turned out to be a faulty engine with bad bearings, & levers. Over time, got worse & left unseen causing it to officially blow. The shutdown modes prior were all left undetected or resolved by dealership service stations. After being told of suspicious knocking since only thousands of miles out on.
