2014 GMC SIERRA 1500 Complaints

The passenger presence module does not work. The deal said if it was involved in a crash there would be a possibility the airbag on the passenger side would not go off because it can't register if someone is sitting in the seat or not.

The contact owns a 2014 GMC Sierra 1500. The contact stated while driving approximately 65 MPH, the vehicle lost motive power and shut off. The failure recurred on several occasions. There were no warning lights illuminated. The vehicle was taken to an independent mechanic and the contact was informed that the failure was due to the oil pump, which had gone into low-pressure mode and shut down the engine.

The manufacturer referred him to NHTSA. The approximate failure mileage was 186,000.

At slow speeds, multiple times, I have had the truck completely have an electrical failure and the engine shut off. I have replaced the negative battery cable and ensured all connections are good. This has happened on streets when turning and in parking lots. When this happens all of the screens in the truck flicker and the service stabilitrack light comes on and then everything goes out, to include the engine. Myself, my family, and other drivers have been out at risk when the truck completely shuts off on a street. The dealership has not been able to give me an answer. There are many forums online where the 2014-2018 year models of this and similar GM vehicles have had the same problem. We need a specific fix for this before someone gets seriously injured or killed.

At low speeds, while turning rapidly steering would get stiff and then come back on.On two occasions, lights would flicker and a steering power loss warning would briefly appear, and then disappear

Break get rock hard at times and makes it almost impossible to stop at a safe distance

Steering will drop out / skip. Electical items have been an issue since I purcased this truck new. Dealer could never find why the wipers trigger randomly when truck is turned on. Truck randomy dies overnight.

The frame on my 2014 GMC Sierra pickup is rusted through on the driver’s side cab area. A truck frame should last longer than 9 years old. Is GM going to do anything about this problem?

Engine lifters keep going bad. The frame is rotting like I have never seen. Body is rusting out for second time. Blows lights every month. Rain getting in headliner and under rear seat. Ac breaks every year. All around worst fucking vehicle I have ever owned. Gmc will not do anything about this. I'm tried

Says I have no recalls. I have terrible gas smell and steering light abs light traction light abs light and hard brake pedal. Seats and mirrors move by there selves. Steering wheel shakes. Overall this truck is worrying me so much I won't put my kids in it. Oh also airbag light on also.
