general problems of the 2016 GMC Sierra 1500 - part 1

Truck has 8l90 transmission, has recently started shuddering at speeds from 65-75 and higher, I am experiencing issues with occasional hard shifts from 1st to 2nd gear, and 2 days ago experienced a very hard shift around 30-40mph when it slammed it made the tires chirp. 85k miles.

My transmission jerks randomly. It's done it since it's been brand new. When it does it, it is usually when it deaccellerates. I don't know if it's dangerous but I was hoping they had a fix for it by now.

Vehicle sluggish upon acceleration. Transmission downshifts unexpectedly. Vehicle continues to rev bounce at steady acceleration and when driving at speed without acceleration.

Paint bubbling on roof. When turning on key, the radio makes a loud buzzing sound. On 11/16/2024, when leaving a traffic light, the truck began surging and shuddering. Tachometer was revving up and down like the transmission was slipping with loss of power while trying to take off and accelerate. While attempting to return home, loud booming noise was coming in from under floorboard. I was unsure if I would make it home before the transmission totally failed. People were passing around me because I was unable to acceleration fast enough because of the shuddering and loss of power. No previous signs of any powertrain issues or failures before. It happened for the 1st time today, and my truck is no longer safe to drive. Gm has known about this transmission issue for years on several different models and has failed to broadly rectify the mechanical problem on all affected vehicles. Instead, gm has allowed the vehicle owners to continue to drive a vehicle with a known problem while it waited for a failure. This put me and my family at risk because I am driving around in a vehicle with a known transmission problem not knowing when it would fail or where I could be located when it failed. Gm needs to pay for all repairs on all vehicles with this transmission failure because gm has known about this problem for years before someone gets hurt or killed. Gm knew about the shuddering problem from the beginning, and they fixed the problem by tuning the transmission which then caused the total transmission failures over time which vehicles owners are not dealing with. Metal shavings are being located in the pan when inspected. Gm should be held responsible for the cost of these transmission repairs. I would have never purchased the GMC Sierra 1500 if I have known gm was installing defective transmissions in new vehicles. That is shady, reckless, and unsafe. Gm, pay to fix these problems.

Transmission began to shift hard at 55 miles per hour on highway. Then when I got to a parking lot it began shifting hard and also in reverse.

The vehicle has been in the dealership from where it was bought numerous of times for the same problem. Transmission shifts very hard from one to two and has lots of slippage. Dealer recommended a transmission flush and it did not fix the problem. They would keep telling me that the transmission is normal for slipping and slamming hard while changing gears. I’ve been to multiple shops and nobody seems to know how to give me a correct answer or guide me on how to fix my problem.

The contact owns a 2016 GMC Sierra 1500. The contact stated while driving at an undisclosed speed, the vehicle stopped moving very slowly and came to a complete stop. The check engine warning light was illuminated. The vehicle was towed to a dealer to be diagnosed. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The contact stated that the vehicle was previously repaired under warranty twice. The manufacturer was made aware of the failure but confirmed that the vehicle was no longer under warranty. The failure mileage was approximately 130,000.

6 speed auto transmission issue with shuttering and will intermittingly sounds like when you drive over the groves on the side of the highway and sometimes hard shiffting between lower gears . It has same issue as being already report with GMC transmission . I have taken truck to local Buick dealership and have them flush fluids and replace filter . Issue has reaccurred . Trans does not slip forward or revers .

The contact owns a 2016 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. Additionally, the transmission started shifting improperly. The vehicle was taken to an independent mechanic where it was diagnosed with a failed transmission fluid control sensor. The contact was informed that due to the transmission fluid sensor failure, the torque converter control module needed to be replaced. The contact stated that the vehicle was taken to several different independent mechanics and the diagnosis was confirmed. The vehicle was not repaired. The contact provided the dtc codes: p0711 and p0700. The contact researched and discovered a previous repair coverage with a similar failure description. The coverage program code was n192291660. The manufacturer was made aware of the failure; however, the contact was informed that there were no unrepaired recalls or coverage for the failure. The failure mileage was approximately 86,624.

My truck only has 40,000 miles on it and has the 8 speed 8l90 transmission. The truck bucks hard and has majorly delayed acceleration, especially on the initial startup of the vehicle. At this point the torque converter is going bad as well as the transmission fluid temperature sensor as per my mechanic when hooked up to the computer. It is now causing a fluttering of the rpms, especially when the vehicle heats up after running for several minutes. It is severely impacting my fuel economy as well as my general safety when operation my truck. This is a known problem with this type of transmission but so far there has been no recall issued, only a class action lawsuit that I am having a hard time joining. It is going to cost me over $8000 for a new transmission and I don't really know where to turn at this point or what to do! please make gm issue a recall for this known transmission problem that they put in millions of vehicles, all having similar problems as my own! thank you!.

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.

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.

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.

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.

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!.

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. 00.

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 “learning” 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.

I pulled out in traffic with enough room to accelerate to the appropriate speed and my transmission begin to shutter and slip. My truck would not go! I was afraid I would be struck in the rear. This was the first sign of malfunction. I took truck in that day to hardy GMC in dallas GA. They informed me my transmissions was ruined. 84,000 miles. I have never towed anything, except golf clubs suitcases, and family members. It shameful that these transmissions are failing around the country with very little wear on them. I repaired the transmissions at an expense to me of $4,500. The warranty on the original transmission was only 60,000 miles, however, the warranty on the remanufactured transmission is 3 year or 100,000 mile. What a joke. Do the right thing. Back your product.

When I was driving down the road the transmission just quit working. But I have had ongoing problems of the truck shifting hard and popping out of gear while driving. I have also went to get on the interstate and the truck pop out of gear while merging in traffic now I can’t go more than a mile or 2 miles and truck quits moving completely. I have to turn truck off then bank on it will drive a mile and do the same thing again which has left me stranded in the middle of the road.

I purchased a certified pre owned 2016 sierra slt in February and just after a month of owning it a notification started to pop up and chime on my dash stating "service trailer brake system". I have had my truck in the shop multiple times after to have this issue repaired and nothing has worked. They replaced the dash gm genuine part 84108373 break controller switch and buttons, the gm genuine part 23337305 trailer brake control module as well as the 7/4 pin 23404450 gm oem trailer tow receptacle. Nothing has fixed this issue! when the truck chimes I lose my trailer breaks and this is extremely dangerous hauling a camper weight 6500lbs. I also lose the ability to make phone calls, hear my blinker also the radio. This renders my truck inoperable and a danger to drive.

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.

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.

Transmission shakes constantly not just when shifting. Repair shop says this is not repairable and is a common issue in trucks like mine. 2016 GMC sierra. Vibrations are significant enough to cause a safety issue. Getting worse with time.

Torque converter went out causing hesitations which led to the entire transmission needing replaced.

When placing the truck in drive, there is a very hard 'clunk' between first and second gear. Additionally, when driving, the truck shakes/shudders, mostly on the highway, but sometimes in town when driving between 25 and 70 m. P. H. The first instance was in March, 2019 whereby the dealer indicated this was normal operation for this transmission. As it seemed to get worse, I took it back and was told the transmission fluid was the wrong type and I had to pay to get it evacuated and changed out, even though this was an error on gms part.

I purchased the 2016 GMC sierra new. From the very start I felt there were issues with the transmission. I took the truck in for the shaking, vibrations and clunking in the trans with 5058 miles. Over the next 36 months I had the truck in 7 times and 3 different dealerships to get the trans fixed. Only once did they really do anything where they changed the fluid. I lived with the issues after the warranty expired as gm would not do anything to fix it. Now at 66,000 miles the vibrations have gotten so severe I am afraid to drive the truck. At no point has the truck not had vibrations, only they have increased. And now I have had 2 check engine warnings both dealing with the trans.

Experienced error code of p0307 after vehicle backfired while on highway. Check engine light and stabilitrak lights immediately turned on and vehicle was shaking violently. Immediately took vehicle to an independent shop to have it looked at. After running diagnostics, pressure tests, and bore scope. It has been determined that piston in cylinder 7 is a complete loss and has a 0 pressure reading. From talking with shop owner he said he sees this issue quite often with gm vehicles due to dod or afm (active fuel management) that gm has on their engines. I'm at just shy of 67k miles, out of warranty, and needing to replace the engine.

Torque converter failed and destroyed the transmission at 79,600 miles.
