2016 GMC SIERRA 2500 Complaints

The contact owns a 2016 GMC Sierra 2500. The contact stated that while refueling, he became aware that the front passenger's side wheel bearing was missing the nut and washers. Additionally, the vehicle made an abnormal jingling sound while driving at approximately 20-30 MPH. The contact, an independent mechanic, replaced one nut and three washers on the front passenger's side wheel bearing. The manufacturer was not made aware of the failure. The failure mileage was approximately 71,000.

I remote started my truck yesterday morning to get it warmed up before loading my family. They all then got into the truck, my 5 year old and 8 year old in the back seat in booster seats. I threw in some more bags into the back of the truck and started to climb into the truck. As I did that my kids were starting to get nervous and my wife was pointing and stating that the rear window slider was smoking. I put the key into the ignition and turned the key on. Upon doing that the smoke stopped but a few seconds later there was a loud bang, similar to a gun shot, and the rear passenger side window shattered. My 8 year old had glass hit her and my 5 year old was hysterical. Needless to say, the 5 hour drive home was not much fun for anyone after that occured.

I am receiving an on-and-off “Service Trailer Brake System” when towing and sometimes when not towing. Checked every component and alert does not stop. When this happens while I’m towing, trailer brakes stop working momentarily.

The contact owns a 2016 GMC Sierra 2500. The contact stated while driving 70 MPH, the vehicle lost motive power and stalled inadvertently, almost causing a crash. There was no warning light illuminated. The contact stated that she was able to veer to the side of the road by dodging traffic. The vehicle failed to restart. The vehicle was towed to the dealer where it was diagnosed that the high-pressure fuel pump had exploded and projected metal fragments throughout the high-pressure fuel system. The vehicle was repaired at the owner’s expense. The manufacturer was notified of the failure and informed the contact that a partial reimbursement would be made. The failure mileage was approximately 114,000.

While Pulling 35' 5th Wheel down freeway, a message appeared in instrument panel telling me the fuel filter was at 0 percent and was going into low power mode. There happend to be an offramp there that I was able to get off the freeway. While making the turn on the offramp the truck died. I pulled over as far as i could whie coasting with no power steering or brakes, leaving truck & trailer partially blocking the offramp. Unable to start the vehicle, I Immediatly contacted Onstar and they dispatched the CHP & tow truck. When CHP arrived he asked when tow truck would be there. Without being able to confirm exactly, and due to safety concerns because of blocking the offramp, he called his own tow truck (Rons Towing) and forced me to move vehicle to safe location. The issue ended up being the injector fuel pump (CP4) that GM was well aware of going out and sending metal fragments throughout the fuel system. I've been told the pump was made in China and not to GM standards. The vehicle has been repaired, all work was covered under extended warrenty, This all could have been avoided if GM would have replaced the faulty fuel pump under recall. Had this happened 100 miles further on our trip we would have been going over Pacheco Pass in Calif. Could have been a total disaster had we been going down the other side with No Power Steering & No Power Brakes pulling a 12,000 lb Trailer in the Dark.

As I was backing into my parking spot I heard a bag then the engine light came on, after that it wasn’t shifting correctly, had it checked out and was told the transmission has to be replaced the mechanic said that this transmission is known to be defective it’s only a 2016 I feel there should be a recall could have been a disaster on the road.

Engine stalled due to fuel pump failure. Dealer had to replace entire fuel system

2016 Denali 2500 Diesel - Loose steering, like many of the others complaining. I only have 13,000 miles on the truck since I don't drive it during Ohio winters (salt) and use it to tow my 6500 lb boat. Doesn't feel safe at all when towing. The dealer explained both the pitman and idler arm were worn. $1500 repair bill. Very frustrating that GM doesn't cover this potential safety related issue regarding vehicle control/stability. Several versions of Technical Service Bulletin's exist #PIT5501D as an example.

The contact owns a 2016 GMC Sierra 2500. The contact stated while driving at an undisclosed speed four years ago, the steering wheel became significantly loose, causing the contact to lose control of the vehicle. There were no warning lights illuminated. The contact depressed the brake pedal and veered to the side of the road. The contact then continued to drive at slower speed and away from other vehicles. The vehicle was taken to the dealer and was repaired under Technical Service Bulletin Number: PIT 5501F; however, after the repair, the front-end of the vehicle and the steering wheel would wobble while depressing the brake pedal. Additionally, the contact stated that the steering wheel failure reoccurred several months ago while driving. Upon inspecting the vehicle, the contact removed the driver's side wheel cover and discovered that the brake fluid had been leaking inside the wheel well and underneath the floorboard under the steering column. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 4,450.
