2025 Chevrolet Silverado 1500

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)

Prior to this incident, I had been having issues with my fuel management system give a “reduced acceleration” warning (codes P0087, P228B) in weather below 28-30F. It was in the shop 3 times prior: first time was “bad fuel”, second had my fuel rail and fuel filter replaced, and third time I had my high pressure fuel pump replaced (also had a rear crank seal leak). While approaching a stop sign, my vehicle gave me a check engine light with a “Reduced Acceleration” warning followed by several other warning messages and then ultimately lost power and shut off give me no ability to steer or brake my vehicle. Luckily, my vehicle came to stop and no crash or injuries occurred. If this had been at higher speeds the outcome could have been fatal to myself or another driver/passenger on the road. This incident also gave me a P0087, P12A6, P228A, and P228B error codes. I was able to restart the vehicle and make it home. The following day, the “Reduced Acceleration” message once again appeared. The vehicle is currently at the dealer awaiting diagnosis and repair.

the following issues with my truck. 1. October 29-November 4. rear crossing traffic not working. front windshield camera not working, side detection now working. 2. 17 December Adaptive Cruise would accelerate when not in use. side camera not available. back up camera not in use, all dash related to the radio, phone and google not working. 3.5 Feb 26 blind spot indicator, forward collision, and rear crossing traffic warning working. 4 with all this issues this vehicle is an accident in motion a safety hazard to me and any body around this vehicle GMC has had this vehicle 4 times and can not seem to get it repaired.

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.

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.
