general problems of the 2019 GMC Sierra 1500 - part 2

Transmission started fluttering around 60k miles. Per GMC dealer - this is due to water getting into transmission from fluid put in at the factory. Even though dealer admitted that it's a defect from the factory, the warranty wouldn't cover the repair. This is a well known issue in the 5. 3l 8 speed trans.

The contact owns a 2019 GMC Sierra 1500. The contact stated while driving 75 mph, the vehicle occasionally downshifted or unintendedly came to a stop. There were no warning lights illuminated. The vehicle was taken to a dealer and the vehicle was diagnosed and the contact was informed that the transmission software needed to be updated. The vehicle was repaired; however, the failure persisted. The contact stated that on another occasion, the vehicle started to turn off unintendedly at traffic lights. The vehicle was taken to a different dealer and the vehicle was diagnosed and it was determined that the valve body software needed to be updated. The vehicle was repaired; however, the failure persisted. The contact stated that on another occasion, the vehicle started to vibrate violently while driving on the highway. The vehicle was taken to the original dealer and the dealer replaced the transmission; however, the failure persisted. The vehicle was taken to a different dealer and the vehicle was diagnosed with torque converter failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 48,000.

The torque converter of transmission went out on my 2019 GMC Sierra 1500 denali with only 62072 miles. My safety has been put at risk daily, from intermittent shuddering and loss of power. My vehicle underwent a multi point inspection at earnhardt Buick GMC confirming I will need a complete transmission assembly estimated to be around $7100. There were no indications or dash lights, the only reason I brought it in is from hard shifts, and intermittent shuddering.

My truck is currently experiencing shuddering when driving. This happens at random times but is becoming more frequent. I have taken it into service shops on numerous occasions, and they have not been able to identify the cause due to my truck not exhibiting these conditions when they are diagnosing it. I have run out of funds to continually pay for diagnostic fees, so I have had to let it go until recently. Now it shudders, shifts very harshly, rpms fluctuate continuously, knocking noise when driving, and in the mornings when I first leave for work, my truck will not shift out of first without revving high in rpms. I took it to a mechanic and was told that it was my torque converter, which has now damaged my transmission. All of which I have to pay for out of pocket. These symptoms started when my vehicle was still under warranty (around 30,000 miles). I even flushed the transmission, and it did not help. This is my daily driving truck, and I use it to go to work and transport my 3 young children around. Most of our driving is done on the highway at high speeds (70 mph). When my truck shudders or shifts harshly, I feel that it is going to cause me to lose control or wreck, putting not only my life but my children's lives in danger. I have not consulted a lawyer, as I do not have enough money to do so. I have not had the manufacturer look at it, because when I called about it, they told me I would have to pay for all service fees since it is out of warranty. The only warning lamps I get is when it goes into limp mode (which is at least once or twice a month) and by the time I used to get it to a mechanic, the light was off and they said there is nothing they could do about it. All of this has been happening to some degree since it was around 30,000 miles and only getting worse. The fact that I have put over $20,000 into this (not including my monthly payments of $990) and now have to replace the transmission & torque converter is ridiculous.

I have had frint driver and passenger ball joints go out 3 times all together.

I bought my 2019 GMC sierra in August of 2019. It had 3000 miles when I bought it. It now has 59000 miles on it and is in the shop today for transmission repair. The authorized dealer has flushed the transmission and I am waiting for a call back. The flush will be in the $500+ range and they charge a $165 diagnostic fee also. The transmission shudders, knocks and grabs when I accelerate. It feels like I have been rear ended. It also leaps from a complete stop. It doesn't accelerate smoothly. I feel this is a dangerous situation. I have called GMC customer service to complain and they have escalated to someone who is going to call me back in 24-48 hours.

While driving down a road in the moring hours, lost complete power and truck shutdown. Thank god, I was able to pull off the road,since it was a Sunday moring. Truck was not able to restart. If this had happened on a busy interstate. My wife and I could have been hurt or killed. Had the truck towed to dealer. Replaced the transfer case module. Still don't know if what they put in truck was correct since mine was different than what was shown on computer specifications.

Oil cooler line detached from crimp while driving at highway speeds forcing the vehicle to an emergency stop on the side of the road. All oil pressure was lost immediately and entire underside of vehicle including tires, brakes, and wheels were all coated in oil. Known issue for same year, make, and model that has already been listed from NHTSA. But, apparently this VIN was not in the affected range.

Transmission is slipping into neutral from a slow start and re-engaging with a hard bang to the point it feels like I’ve been rear ended from a vehicle behind me. It’s done it twice in two weeks and it seems to happen when I’m leaving from a stop or slowing down and then come back into the accelerator.

The transmission causes the vehicle to shudder, lurch from a stop, at times it won't move forward (from a stoplight etc), it won't reverse other times. When driving down a freeway, the transmission allows the engine rpm to surge wildly as if I had put it in neutral and pressed the accelerator. This started at 85k miles approximately. It's into 90k now. The transmission had to be replaced at a cost of $6000.

The contact owns a 2019 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, the transmission unintentionally downshifted into first gear. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to a dealer, and it was diagnosed and determined that the torque converter needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was towed back to the dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 86,000.

Stopping at a light and transmission jerks forward, almost causing me to rear end and other vehicle. Transmission jerks and clunks forward.

When I first start the truck up and reverse out of my driveway once I shift it to drive it hesitates and feels as the transmission slips from 1st to 2nd gear. Makes it a safety issue due to the truck launching forward once the acceleration kicks in and the revolutions are high once the truck starts its speed from the hesitation.

When shifting to park the vehicle shuts down but message comes up to shift to park and electronics stay on. Vehicle is off but unable to exit vehicle and lock it since the shift to park messages keeps dinging.

Transmission has created shuttering at speed and jarring total stop decelerating from 2nd into 1st gear. Beyond the transmission this vehicle completely stopped and lost power at 55 mph due to faulty valve lifters and pitted cam lobe. These were two separate incidents. Transmission cause lose of power on incline. Valve lifters cause lose of power at high speeds. The dash board read outs no longer worked and I was on a highway without the ability to maintain speed.

While driving down the highway at 70 mph, the transmission slammed into gear and the engine died. A message appeared and said shift to neutral and press the ignition button. The check engine light also appeared. This had been a problem that first appeared at 48,000 miles. I was told that gm recognizes that there is an issue with the transmission, but that it would not damage the vehicle so it is not able to be repaired under warranty. The dealership advised that I should change the transmission fluid, so I did. The transmission continued to slam into gear thereafter. Fast forward to 55,000 miles where the truck completely died. The engine would not start and the truck had to be towed to a dealership. The next day the dealership told me that they had figured out the issue and that it was related to the fuse box and the ignition. I picked up my truck the next day, and drove less than a mile before the engine died again. I sat at the dealership for 12 hours and they had another answer for what was happening. They said that the shift lever was damaged and it was not allowing the battery to recharge. I live 400 miles away from where the truck broke down. I had to rent a vehicle to return home with my family from a trip. I now have to drive back to my truck in another state, and pay for the 12 plus hours of diagnostic work at $140 an hour as well as the cost of the part and the time to install it because the dealership stated that this is not covered by any warranty. I see that several people are dealing with a similar issue and I am frustrated that no one is willing to help us right this wrong. My grandfather worked for gm his entire adult life, and I will never own another one.

Oil coolant line snapped causing low pressure. Vehicle had to be turned off and towed to local garage.

Transmission hesitate going into 2 gear.

The vehicle jerks when I put it in reverse or drive. And when I'm going down the road while it shifts gears. It's be doing it since I purchased it (new). It was light at first but lately its been worse. I took it to the dealership a couple of months ago & they replaced something small & said it was fixed. But it still bad. My truck still only has 30k miles.

The contact owns a 2019 GMC Sierra 1500. The contact stated while accelerating from a complete stop, the vehicle hesitated and the transmission experienced a hard shift to first gear. Additionally, the contact stated that the vehicle was shuddering while driving at slower speeds. There was no warning light illuminated. The vehicle was taken to the dealer but was not diagnosed or repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a related recall. The failure mileage was approximately 38,000.

Hard shift on take off from 1st to 2nd gear and while driving around random hard erratic shifting. Feels like pickup is getting rear ended. Have take in to gregg lair in amarillo TX and they have reset shift points to no avail. I talked to head service writer and he stated that gm had a problem with their transmission but did not have a remedy for them. He advised to drive for about 3,000 miles and we have and still have the issue. We have been back multiple times and gregg lair states that it is still in learn mode after over 10,00 miles. I am a mechanic by trade and in my opinion there is a design flaw with the transmission and/or they have the wrong transmission fluid for the design.

The transmission on this truck it’s not good first they said it was the torque converter then they said it was the valve body ,it work for a few days and I told them before they change any of that that the transmission was making a rattling noise they just patching the problem not fixing the problem told them to give me a new truck or new transmission but they just keep patching the issue I been at cullman dealership like 7 times ,, also had a p25a2 code had a check engine light I told the dealership about and they didn’t do anything about it bc the check engine light wasn’t on anymore.

The contact owns a 2019 GMC sierra. The contact stated that while shifting gears, there was an abnormally loud banging sound detected. The vehicle failed to shift into gears. The wheels were slipping and pulling while driving at various speeds. While traveling on the road, there was an abnormal rumbling sound. There were no warning lights illuminated. The vehicle was taken to the local dealer, who was unable to determine the failure. The vehicle was taken to another local dealer, joe ball GMC, 1750 william flinn hwy. , glenshaw, PA 15116, where it was diagnosed the transmission needed to be flushed and drained. The dealer informed the contact to drive for 200 miles. The dealer recommended replacing the transmission. The vehicle was repaired, but the failure recurred. The manufacturer was contacted and referred to the NHTSA hotline. The approximate failure mileage was 30,000.

Transmission shudder, jerk, high engine rev and transmission look ing for a gear to go in then it jerks. Traded this truck to GMC to get rid of it. Cost me extra money that I would not have spent otherwise. Only had 22,000 mi on it.

Transmission jerks, slams, forces a feeling of being rear-ended, delayed acceleration with sudden engagement causing uncontrolled acceleration. I've had it looked at every time I've taken it into the dealership for regular maintenance. They haven't been able to reproduce it as it only happens once, first time after not driving it for a while. No warning lamps or messages ever appear.

Transmission hesitates. Transmission jerks when shifting. Possible torque conversion issues. Mileage is 35,623.

While driving the transmission shifts very hard. And when starting to accelerate from a stop the transmission slips.

Transmission makes a noice like a kick when stops and sometimes when starts.

Transmission shifts hard first 3 gears. Rear end clunks brakes squeak when going in reverse when putting in reverse gear goes in hard seems to be doing more often.

Since I bought the truck, it has had transmission problems. The truck will violently jerk forward between park - 1st - 2nd gears (up and down) pretty frequently. The dealership denied being able to recreate the issue and nothing was wrong. After dropping the vehicle off a few times, the dealer service dept said they recreated the problem and replace the torque converter. It did not work and the service dept manager told me that they knew about the problem the whole time but were instructed by general motors to not attempt to fix the issue. I called gm company and a supervisor eventually admitted to knowing of the transmission and engine issues all along but the gm engineers have not found a solution yet but they are working very hard to figure it out. Since those calls, my lemon law claim with bbb auto was approved, but suddenly denied with no explanation. Following that, the #2 lifter failed and damaged the cam shaft. All were replaced and that was at 70,000 miles. The transmission has not been fixed.

Driving at roughly 3 miles per hour in 4 wheel high on a gravel road. The axle broke and the tire collapsed. I strongly believe something is defective. (maybe a weld issue?).

Transmission feels sluggish and jerks. When coming to a stop feels like your being rear ended. Stereo system freezes and goes silent no sound what do ever.

The contact owns a 2019 GMC Sierra 1500. The contact stated that while idle or during acceleration, the vehicle would independently surge forward without warning. The contact had taken the vehicle to master Buick GMC (3710 washington rd, augusta, GA 30907) where on two separate occasions he was informed that the mechanics were aware of the failure however, there was no remedy for the failure. The manufacturer was not notified of the failure. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 20,000.

The contact owns a 2019 GMC Sierra 1500. The contact stated while driving approximately 20 mph, the vehicle started shuddering. The contact stated no warning light was illuminated. The contact took the vehicle to the local dealer, but the mechanic was unable to determine the cause of the failure. The vehicle was not repaired but continued to experience the failure. The contact took the vehicle back to the dealer a fifth time and requested that the transmission fluid be flushed and refilled. The vehicle was repaired but continued to experience the failure. The manufacturer had been informed of the failure. The failure mileage was approximately 16,000.

Every single day I back out of my driveway and when I shift into drive and step on the gas the truck moves forward slightly and the rpms wind up but the truck bogs down like it's got a fuel clog then it shifts into 2nd at a high rpm and jerks forward like someone popped a clutch. This is a major safety issue because once this winter it happened and the real wheels spun and the back end slid out on the ice and the nose of my truck wound up in the oncoming lane of traffic. Dealer and GMC say that a �hard shift� is a known issue and the truck is �working as designed� and there is nothing they will do further. I have had it in the shop 3x already. I have read forums speaking of many people having similar issue with 2019 GMC trucks and no fix from GMC. This is not normal, safe and I'm sure no engineer designed this transmission to work this way.
