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 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.
