The contact owns a 2015 GMC Terrain. The contact stated that after starting the vehicle, the message "Power Reduction Mode" was displayed, and the vehicle stalled. The contact stated that after restarting the vehicle, there was a ticking sound coming from the engine compartment before the vehicle stalled another time. The vehicle was towed to the local mechanic who diagnosed the vehicle and determined that the engine timing was faulty, and the engine had experienced a loss of engine compression. The contact was advised to contact a local dealer for service. The vehicle was not repaired. The manufacturer and local dealer were not yet contacted. The failure mileage was 160,000.

My wiring harness which affects all systems. I was on the Interstate when out of nowhere any and all warning lights came on. The power was cut and rapidly slowed down. I also pulled into traffic and the truck just lost power. The problem was confirmed by dealership. The vehicle was inspected by dealership and wiring harness was the issue. The issues appeared out of nowhere. All the warnings lights came on at once. There has been numerous issues with this part and it’s even recognized by just.

I know this is a well known issue with these trucks. Have had issues with power steering not working at low speeds which they claim it’s do to low voltage. This has happened numerous times and then on May 3rd I went to back into my driveway off a busy state route with hills on each end of the road. Put my hazard lights on let three vehicles pass and then I turned the wheel and gave it gas soon as the truck got into the middle of the road it shut off. Everything stopped working no hazard lights for about 10seconds and then I had to put the truck into park turn ignition key off and then back on to restart the truck. Again this is all do to low voltage from what everyone else has said with the same issue. There are no warnings what so every even the voltage meter is fine and the truck doesn’t hesitate at all it’s like someone disconnected the battery. I’m sure there is a way for GM to reprogram the pc for the voltage drop. At least have something like radio go out or ac, heat other than the engine and entire electrical shutting off. Something like this is going to get someone killed and GM should be held accountable for these problems.

Not inspected by anyone else because they have no idea where to look because the light and actions happen on and off. Warning light and message appears. Service Traction Control and service Stabilink Light yes I will bring it in. It will turn on randomly at this point for about 4 months and the brakes are locking up the wheels while driving.
