The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that the door locks were independently locking and unlocking, and the hazard lights were flashing intermittently. The contact stated that the interior lights and the headlights were activated without the contact using the key fob or manually turning the lights on. The contact stated that the 12-Volt battery and alternator were replaced, but the vehicle still experienced electrical failures. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the door lock actuator and the wiring harness needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The manufacturer was not informed of the failure. The failure mileage was approximately 129,000.

While driving, the radio and all other electric components will go dark or quit working altogether, including the AC blower, compressor, headlights, etc. Sometime I get the stabilitrack alert with 3 or 4 tones, which resets automatically. When waiting in a drive through line today, when I depress the brake pedal, it happens again. While waiting in line, I sometimes put the transmission in park. When I depress the brake, and move the transmission control into drive, it happens, and more frequently, the engine shuts off. When turning the wheel, the power steering seems to go out, making it almost impossible to turn the vehicle, all the while the stabilitrack alarm goes off, the headlights go dark, the AC shuts down, the dash display goes dark, the door locks cycle up and down, and the engine shuts down. Today, it almost caused me not to negotiate turning from a major road into a parking lot. I lost all power to the steering, the engine shut down, and my brakes were non-existent. After reading other complaints on here, I decided I needed to tell my story. I received the recall notices, and have not ventured to the dealership for repairs, fearing exposure to the covid-19 virus. After reading everyone else's problems, and hearing that even the recall repairs do not fix the problem, I cannot help but wonder if there is more going on here than gm is willing to admit. I will not let my wife drive this vehicle, because if it happens to her, there is no way she can maneuver a stalled vehicle with no power steering and no brakes. So it looks I have the same story as others, and no real solution to my problem that the dealerships are willing to fix, or even admitting that there is a problem.

The power door lock actuator quick working around 36k miles making it impossible to open the affected door(s) from the outside and can only be opened by pulling the inside door handle which is difficult with a crew cab. I fear that if a belted passenger who is unable to unbundled in a accident or fire may be subjected to danger. I have read of these lock actuators falling earlier the average and general motors will not cover the repair past the exact manufacturer warranty limit.

I was at a stop sign trying to make a left hand turn and the truck steering locked up and then it happened again in a drive thru fast food place. I'm scared it's going to cause me to wreck while driving. I have no control of the truck when it happens and my lights, radio, and door locks go out then come back on.

Combo 4 pin and 7 pin trailer connection is upside down. This may result in the loss of trailer lights and brakes. With connection upside down the 7 pin door will not hold plug in tightly and cause the brake and ground pins to possible disconnect. Loosing brakes while pulling a heaving load is a serious safety issue. Plug needs to be inverted to ensure the door latch holds the plug at the high point and weight of the cord holds the plug in tightly dealer is aware of the issue and gm engineer is aware of the issue.. Neither has yet to fix. Same design exists on 2013 and 2014 silverado's 1500, 2500 and 3500.
