This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
There is a torque converter recall on the 2014 GMC sierra 1500 however my vehicle was not included in the recall but my transmission / torque converter went out.
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.
The contact owns a 2014 GMC Sierra 1500. The contact stated while driving 50 MPH, the transmission inadvertently shifted to neutral(N) and the vehicle stalled. No warning lights were illuminated. The contact related the failure to NHTSA Campaign Number: 14V374000 (Power Train). The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was 112,000.
My lifters bent and my valves collapsed. I have had the vehicle repaired twice. No engine light warning. Also in Nov of 2022 oil is leaking into my cylinders. Common problem on several GM forums.
The contact owns a 2014 GMC Sierra 1500. The contact stated while his wife was driving approximately 65 MPH, the vehicle began to vibrate and made loud grinding sounds. The contact stated that the vehicle began to lose motive power. The contact's wife was able to exit the highway; however, the transmission was slipping out of gear. The contact stated no warning light was illuminated. The contact stated that the failure had become constant. The vehicle was not taken to a local dealer or independent mechanic to be diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was 94,302.
Going under 15mph, applying the brake causes the pedal to become stiff and lock up and not work. This has caused me to almost hit someone in traffic. I immediately got off the road and got my vehicle to a safe location off the road. Communicating with a dealer today to confirm possible recall issue or potential repairs.
My vehicle recently started "shuttering" while driving. Service report says it is a "common GMC issue with the Torque Converter", $3200. They also reported a "substantial leak" in the radiator, and again, says it is a very common fault of GMC Trucks. And another $2700. If these conditions are as common as they indicate, why are there no corrective measures?
I was driving and was almost home when I heard a pop and started getting jerked back and forth and then just slowed down almost to a complete stop with vehicles approaching quickly almost causing a multiple vehicle pile up I-??ve heard multiple people complain about the particular transmission that is put in these gmc and chevy 1500s and am just confused with all of the problems I see on the internet and hear from peers in person why it has not been recalled yet if need be I will make a survey of gmc and chevy owners to let it be known that the transmissions on these vehicles were poorly built and need to be recalled before anybody has this problem that I had today
From time to time the vehicles power system will surge, blink, and generally act up. The priblem is intermittent. The check engine light will come in then go off, the engine has completely cut off several times while driving, the transmission acts up, radio will turn off, 120v outlet will turn off, occasionally the vehicle will fun for 5-15 seconds after being turned off and then sputter off. And 95% of the time the truck is absolutely fine.

The vehicle was taken to the local dealer Liberty Buick GMC (9028 E independence blvd, matthews, nc 28105, (704) 708-8000) however, the mechanic was unable to duplicate the failure. The contact stated he continued to experience the failure. The contact also stated while driving at low speeds, there was an abnormal sound coming from the front driver's side wheel axle. The vehicle was taken back to Liberty Buick GMC where the mechanic was unable to duplicate the failure. The vehicle was then taken to griffin Buick GMC (2500 w roosevelt blvd, monroe, nc 28110, (704) 289-3135) where it was diagnosed with needing the front driver's side strut to be replaced. The vehicle was taken back to Liberty Buick GMC and the repairs completed. The contact also stated while driving at an undisclosed speed, he heard an abnormal sound coming from the vehicle.

The vehicle was taken back to Liberty Buick GMC and the contact was informed that the gearbox needed to be replaced. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 87,000.
The vehicle's transmission makes clunking sounds, and jerking movements when accelerating and decelerating (highway). When stopped on an incline the vehicle drifts backward, once your remove your foot off the brake (street). The vehicle has rolled backwards while it was fully parked and unoccupied.
I was driving down the road and all of the sudden it was if my transmission disengaged and my car lost power. It then automatically came back on and the 'service stabilitrak' lights came on. I nearly avoided an accident and was able to pull off onto the side of the road.
I have had to replace my condensing unit two different times. Once at 75,000 miles, which was covered by my extended warranty that I purchased, not by GM, and the other broke at 107,000 miles in the exact same spot, which I had to pay for. This is a joke! I have also had to replace my oil cooling lines two different times, which were also not covered under warranty.
