2025 Chevrolet Silverado 1500 Electrical Problems

Your truck's audio system—including the radio, turn signal sounds, and collision/lane departure warnings—cuts out completely and randomly, leaving your cabin completely silent. While losing radio audio is inconvenient, losing safety alerts is a serious hazard since you won't hear warnings about potential collisions or lane drift. Your dealer thinks a software update might be responsible, but the problem doesn't seem to follow any pattern. The fix will likely involve a software reprogram or electrical system diagnosis to restore normal audio and safety alert functions.

Your infotainment screen wouldn't turn off and Bluetooth kept disconnecting, so the dealer replaced the infotainment center. After the repair, your check engine light came on with an "Engine Power Reduced" message. The dealer diagnosed that your engine had failed due to thrust bearing problems and needed complete replacement at only 3,000 miles. The manufacturer has been notified and opened a case to investigate the failure.

Your engine failed to start or shut down unexpectedly. This could involve issues with the electrical system, engine components, or fuel delivery. You should have a mechanic diagnose the specific cause before attempting to restart the vehicle.

While driving at 30 mph, your engine suddenly shut off with a popping sound, leaving you stranded in the middle of a busy intersection with no power and unable to restart or shift into neutral. The hazard lights worked only intermittently, and you had to disconnect and reconnect the battery roadside while police controlled traffic. After restart, your check engine light came on and the OnStar app showed transmission, ignition, and engine electrical warnings. Your dealership has had the vehicle for 7 days without being able to diagnose the problem, and the fix will likely involve electrical system diagnostics and potential replacement of battery, alternator, or ignition system components.

Your truck has experienced multiple safety system failures including rear cross-traffic detection, front windshield camera, side detection cameras, and backup camera not working. Your adaptive cruise control has unexpectedly accelerated on its own, and your dashboard infotainment system (radio, phone, and Google integration) has stopped functioning. Despite four service visits to GMC, these issues remain unresolved. The fix will likely require camera sensor inspection and replacement, electrical system diagnostics, and infotainment system software updates or module replacement.

Your truck's SuperCruise adaptive cruise control failed to turn off while driving at 55 mph in heavy traffic—pressing the SuperCruise button, cruise control button, cancel button, and brakes all had no effect until the truck finally slowed on its own and activated hazard lights. Your truck has required multiple dealer visits for "Service driver assist" issues, camera repairs, and software updates, but these problems have continued. This is the first time SuperCruise itself failed to disable.

Your truck's wireless Apple CarPlay system automatically connects your iPhone to the vehicle's Wi-Fi network, which blocks your cellular data even though the Wi-Fi doesn't provide internet access. This means you lose navigation, traffic updates, and streaming services while driving, and there's no way to disable this behavior in the vehicle settings. Wired CarPlay works fine, but wireless CarPlay as advertised doesn't work properly. The fix will likely require a firmware update to the infotainment system to allow cellular data to remain active during wireless CarPlay use.

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 contact owns a 2025 Chevrolet Silverado 1500. The contact stated that while driving at various speeds on several occasions, there was discrepancy between the speed limit displayed on the infotainment system and the actual speed limit posted on the road. The contact sated that while driving at an undisclosed speed on a residential street, the infotainment system displayed that the speed limit was 55 MPH while the posted speed limit was significantly lower. The vehicle was taken to a dealer, where the failure was acknowledged, but the contact was informed that the remedy to correct the failure was not yet available. The manufacturer was notified of the failure. The failure mileage was approximately 75.

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.

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the instrument cluster displayed a black screen and seized. The contact stated that occasionally the instrument cluster failed to activate. The vehicle was taken to the dealer, where it was diagnosed with instrument cluster failure. The contact was informed that the instrument cluster needed to be replaced. The vehicle was not repaired. The contact was informed that the parts were not available to repair the instrument cluster. The contact referenced an undisclosed recall; however, the VIN was not under recall. The contact stated that the failure started immediately after the vehicle was purchased. The contact had been waiting for delivery of the parts for two months. The manufacturer was made aware of the failure, and a case was filed. The contact stated that the manufacturer had been contacted more than twenty times. The failure mileage was approximately 2.

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated while the vehicle was parked in the garage, the key fob was accidentally depressed twice. There were no warning light lights illuminated. The contact stated that the design of the key fob was different from the key fob for a similar vehicle the contact owned, just an older model. On the older model, whenever the contact pressed the key fob and the lock button was pressed, the vehicle would start. The contact stated that on the new vehicle, when the lock button was pressed twice the vehicle would start unintendedly while the vehicle was in the garage. The contact stated that on another occasion, the key fob was pressed twice unintendedly and the tailgate open, and the vehicle started. The contact believed the failure was caused by a defect. The vehicle was not taken to be diagnosed or repaired. The dealer was not made aware of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 3,000.

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.
