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.
The transmission overheated due to a poorly manufactured torque converter which caused my truck to come to a sudden stop on the interstate nearly being struck by several semi tractor trailers leaving my family and I in a dangerous situation. Upon research the torque converter and the thermal bypass valve fail causing the transmission to overheat with no warning whatsoever. It massively blew smoke out of the tailpipe blocking all lanes of traffic, completely unable to see that I'm broke down and nearly caused several accidents. Police was not notified since no accident occurred. The transmission preformed as its supposed to. No hard shifts or slipping between gears. This needs to be addressed by the NHTSA and GM as it's a huge safety issue. With no warning light indicating the transmission is reaching critical heat levels and shutting down poses a risk in the event you're towing a trailer/camper (As I was). Or even worse happening to those who live where they drive up and down steep mountain grades.
The electrical system keeps throwing a code for short to ground as well as low voltage codes. The voltage gauge on the dash shows either over charging or under charging. The in dash radio and screen shut off and turns back on by itself while driving down the road. Occasionally while backing up or pulling forward the truck completely stalls. The transmission was subject to the shudder issue, we took it to King Cadillac in Lake City, SC for the transmission flush. After the flush we have not felt the shudder, but instead Occasionally when pulling off from a dead stop, or while crossing the very busy highway my house is on the truck looses momentum almost as if the transmission is failing to engage at all, and all of the sudden about 15 seconds later it engages and accelerates at a rapid rate. The steering is extremely loose in the tires, however the steering wheel engages after about 3/4 of an inch. I have taken it to said King Cadillac multiple times and they maintain that the steering is 100%. Although I can not let go of the steering wheel and continue straight for any length of time. I am constantly having to adjust the steering to match the pull of the vehicle to avoid changing lanes or running of the road. After 60mph the tire shake is horrible, after 70mph it is hard to keep the truck in its lane.
Transmission problems. Had to replace at 95,000 miles. Seeing problems online with same GM pickups with less miles and transmissions going out. General Motors has a problem and not addressing it.
Check engine light on 2016 GMC Sierra, PO710 and PO711, took to local mechanic and notified me there is a service bulletin related to issue but VIN# shows no recall, below is the service bulletin found online. PIP5700 8L45 8L90 Internal Wiring Harness I
When in park and I shift the transmission into Reverse, the force engaging the gear bangs and shakes the vehicle. The transmission is not regulating the power. The vehicle is available for inspection. I took the vehicle in to the dealer service and they were able to reproduce it. They claim that there is a bulletin from GM motors and this is considered normal. The bang is hard and shakes the vehicle, definitely not normal. It started after 50k miles and the truck has 62k miles now. No one else inspected the vehicle and no warnings are indicated by the vehicle.
The torque converter jerks the truck and causes vibration. This does jerk the vehicle unsafely at times of stop lights. As I know this was a lawsuit at one point with GMC itself. It does nothing but get worse with pulling and jumping the truck going down the road.
Transmission changes hard when it shifts to another gear when I purchase the truck new I contact GMC they said that it was design to shift like that everyone that I know has a Sierra 1500 complains about how hard their truck shifts I have relatives and friends complains also. When it was under waranty they told me that the wrong tramsmission fluid was put in it from the factory ? my truck brand new.
I drove up to a yield sign, when on coming traffic was clear I step on the gas then I heard my engine knocking I tried to go but I only could get up to 30 mph I took it to the dealership they diagnose it and said that the number 7 cylinder had misfired I had a manchanic to repair it and it cost me $4200.
Torque converter and pump assembly failed at 66k miles 2016 GMC Sierra. Currently being repaired by the dealership. They first quoted me $4200 to replace but was able to talk them down to $3100.
At low/idle speeds the brake pedal becomes hard and will not stop. At speeds between 35-75mph the engine/transmission has a vibration about every 10seconds and the transmission shifts hard and/or rough at times when first taking off.
Took my truck to gmc dealership to get brakes and transmission fluids flushed, then a few months later I noticed that my truck started shifting hard. then one day going back home from work I lost 6th and 5th gear, would not go into either one. then I lost all gears and would just red line when I pressed the gas. had to coast into a parking lot to get a tow truck and carry it to a transmission shop. the shop said that the universal clutch was burned up and would now cost me $5,000 to fix.
Just purchased this used vehicle in December 2022 with high miles (202000) with a dealers extended warranty. Problem has happened twice in 2 weeks. While backing up slowly and turning my wheel the vehicle stalled and Service Stabilitrak came across the dash as it died. Then upon restarting it told me to roll drivers window down and up and the memory seat function cleared as did my clock. Like it had a battery replacement and reset to factory. Took into a GMC service shop where they found code P0700 and P0711. They were able to replicate my concern. Telling me to replace the transmission harnesses and that it is not covered under my extended warranty for powertrain. Going to cost me $1500 in repairs. After extensive research I see this is a common problem yet no recall has been issued for my 2016 GMC Sierra crew cab. Very frustrating!!
Was in a parking lot, moving just 2mph and had to literally mash down on the brake pedal - both forward and backward. Also, I put my truck in drive and has been making a noise in the transmission it seems and is a loud + lurches forward a bit. Additionally, I was traveling on vacation to Rockport, TX. I've made a appointment with the dealership here at 10:00 A.M. on 9 Dec 22, it's the earliest I can get my truck in. There was previously a brake issue covered under warranty & should be again!
After an unexpected battery failure, truck shuttered and jerked violently when coming to a stop. Replaced battery and was driving home when shuttering returned and dropped into neutral as if it was trying to find the gear. Pull over and was within inches of being rear ended as it rolled to a stop on shoulder. Forced to abandon vehicle while waiting for tow truck for safety. Concerns were raised to dealer around 50k miles when something seemed off, but was dismissed with the excuse that it was normal. Now with 120k, I have nothing more than a $45k yard ornament.
My transmission shifts very hard from first to second gear, and when accelerating onto a freeway. It literally jolts the entire vehicle. Recently on two occasions at less than 5 mph it shifted so hard it felt as if I was struck from behind by another vehicle. I-€™ve been told by my local GMC service department that it is a -€œlearning-€ transmission and it-€™s learning how I drive. That was their remedy.
Vehicle shakes and shudders. Transmission required to be replaced at 70,710 miles. Dealership said the torque converter and transmission failure is a common event in these vehicles and wasn't covered under warranty
Transmission Harsh 1-2 shift. Under light or heavy throttle. While driving the vehicle on first or second shift the vehicle has a delay to engage into shift making it a safety issue under normal conditions. If shift happens under rain will activate traction control almost making you lose control. Due to transmission not engaging correctly or delayed. Upon slowing down the transmission down gear feels as if someone hit my truck from behind. Feels like whiplash from initial engagement to first and second gear and again whiplash for passengers especially kids in car seats when slowing down. # 16-NA-361 information on Transmission Harsh 1-2 shift. This is the bulletin GMC has put out in response to my hard shift when I took into dealer for repair. It also gives the direction DO NOT Replace any parts for this condition. This issue also began at 40k miles and under warranty Dealer doesn-€™t want to fix. At 80k miles even no warranty dealer won-€™t fix due to no check engine light on. How can the dealership state they can-€™t repair the issue being a safety issue. Or give another options to help fix the issue. Other than just buy a new car and hope it doesn-€™t have the same issues
While putting truck into gear the transmission will not engage and will rev up and then take off or when coming to a stop the adaptive shift clunks very hard as if someone has hit you from behind. It will then surge forward without any warning. I have had it in to the dealer several times and they tell me it a know issue but they wont do anything about it.
