2014 GMC SIERRA 1500 Complaints

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.

The power steering started going out and then comes back on, which is very dangerous!

The headlights are dangerously dim, can't drive the vehicle comfortably at night. There seems to be no solution for fixing them. A TSB has been issued concerning this, but does little to address fixing the problem.

When I am braking at low speed my brakes start locking up and eventually do not work. This has happened on multiple occasions. I have almost wrecked multiple times I rarely drive my truck now cause it is unsafe. There is a recall on the brake booster 2014 to 2018 gmc seria but my truck vin is not included on that recall and it’s doing the exact same thing. GM recalls 3.4 million pickups and SUVs over brake pump Sept. 12, 2019 1 The recall includes the Chevy Silverado and GMC Sierra (model years 2014-2018), and affects a vacuum pump defect that may make it more difficult to brake at low speeds.

Back up lights and Tail light problems My Back up lights turn on when the headlights are turned on and do not shut off unless the headlights are off. Also, recently, the rear tail lights were burning out early and would last only two weeks. The source of the problem seems to be in the fuse box. There is no short in the system. It appears to be in the fuse box of the 2014 GMC Sierra 1500. Bulbs were replaced and burned out quickly. Replacement parts are expensive and this problem exists on other Chevrolet and GMC trucks.

The contact owns a 2014 GMC Sierra 1500. The contact stated that while driving at slow speeds, the power steering assist intermittently failed to operate as needed with the "Steering Assist Reduced - Drive with Care" message displayed. Upon investigation, the contact discovered NHTSA Campaign Number: 17V414000 (Steering) which was linked to the failure. The vehicle was taken to a local dealer where the contact was informed that the vehicle was previously repaired under the recall and that the vehicle was no longer under recall. The manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

Both headlamps stopped working when driving at night. Neither the low or high beams will work

Remote started my truck. Went to get in my truck about 10 minutes later. There was smoke in the vehicle. The rear defrost shorted and melted a hole in the rubber seal next to my rear sliding window. The heat from the incident cracked and spider webbed my rear window.

On my 2014 GMC, the front driver side seatbelt was not latching. We had to finagle to latch it. To which this point we were unsure that we were safe. So I brought the GMC to the GMC Rosedale dealership and after further investigation they charge me $522 to repair replace the belt. I told them it’s a safety issue, but they seem not to care, I also contacted GMC corporate and they are investigating this. So if it state law that you have to wear a seatbelt for your safety, why do dealerships charge you to repair or replace them.?

The contact owns a 2014 GMC Sierra 1500. The contact stated while driving 50 MPH, the passenger’s side headlight became inoperable. The contact stated that several unknown warning lights flashed on the instrument panel. The contact pulled over to inspect the vehicle and discovered that the water pump had failed. Despite the failure, the contact managed to drive the vehicle home. The next day upon starting the vehicle, the check engine warning light illuminated and both engine fans began to run at full capacity. The contact called the dealer and made an appointment for a diagnostic test. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 160,000.
