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 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.
The contact owns a 2019 GMC Sierra 1500. The contact stated while driving at various speeds, the vehicle loss motive power with the check engine warning light intermittently illuminated. The contact stated that on most occasions, he would be able to restart the vehicle and resume normal driving soon after failure. The contact had taken the vehicle to a dealer on 4 separate occasions and each time the contact was given a different diagnosis. Despite the several diagnoses, the failure persisted after each visit. The manufacturer was also notified of the failure and each time referred him back to the same dealer. The manufacturer offered no further assistance. The vehicle had yet to be repaired. The failure mileage was approximately 5,000. The VIN was unavailable.
Transmission shakes rattles and jerks and has since I got it brand new. Intermittent issue normally but sometimes it's extremely aggressive and legitimately causes a whiplash motion
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
2019 GMC Sierra with 56K miles when accelerating transmission seems to get stuck in first gear makes idol sounds rpms jump up then hard shift into second, makes the truck jerk when it happens, since the issue started it happens every time I drive it. I took it to local GMC dealership on 2/9/21 manager said 'yes it's a known issue with GMC & that year model trucks' 2 days later called to see status of truck manger said his transmission guy found the issue and fixed it said computer and transmission not talking to each other did a 'transmission relearn' was covered under power train warranty. I had the truck back less than 24 hours and now back to having the same issues again! clearly it's not fixed and concerning this is going to be a safety issue while driving! GMC 'known' issue then issue a recall and fix it right the first time!

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
While driving the vehicle 21oct2020 it started whining and jerking. I called the dealership to have it checked they couldn't see us, so we took it to a different GMC dealership that said the codes had not been updated, they preformed the recall and said it should be fine. Two days later it started jerking again and shut off when stopped at a light. I took it to the GMC dealership we bought it from on the 28oct2020 and I was told that the truck was fine, and that the diagnostics showed no problems whatsoever. The tech said he would drive it out of the bay, if brittany would open the door and before he could drive it through the garage bay area and out the garage bay door the truck made a crazy loud noise, jerk to a sudden stop and the transmission went out, and the truck would not restart at all and had to be towed out of the bay door. The 2019 truck has had 5 recalls for safety issues and with 40,000 miles the transmission went all the way out and the truck has been sitting there at the dealership for over a month waiting on the new transmission to come from GMC. I go in and see the transmission recall on so many 8 speed transmission which this truck has, and now I feel like I was sold a lemon and no one seems to care. % recalls and the transmission goes out completely at 40,000 miles. I am so upset about it that I do not even want the truck anymore. It is going to ruin my resale value and the lemon law should apply on a truck one year old. I have filed complaints with the dealership, and now on their front door is a sign that says they will not honor the warranty policies on any vehicle they sold after November 15, 2020. Of course they sold me zurich extended warranty too, and I can promise I will never buy GMC again. I also have a 2017 pathfinder almost paid off, that I am giving to my daughter, and I was going to get an GMC arcadia but not a chance now.
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?)
First feeling was, I was driving in a parking lot going maybe 5 miles an hour and I felt a vibration in the brake pedal. Pulled onto the main road and approached a stop light when the truck stopped a little hard as I was depressing the brake pedal. As I started pressing on the gas when the light turned green, I was traveling around 35 mph or so, when the truck came to a complete stop in which myself & passenger were slightly thrown forward due to the abrupt stop for no apparent reason. The vehicle in back of me nearly rear ended me due to the abrupt stop the truck did. I immediately contacted the dealer, in which after several days in the shop, the dealer told me that GMC knew about this particular issue but has not issued a recall. The dealer was instructed to replace the transmission control module, due to a malfunction in the tcm that apparently was trying to shut the truck down completely. Therefore causing the truck to stop abruptly with no warning.
The transmissions will shudder and delay shifting gears. I have pulled into a parking lot and put it in park, then I realize I'm a foot back I put it back in drive, the car doesn't do anything for a second then it lurches forward in an unsafe / uncontrolled manner. Often backing out of the driveway, then putting it into park and the same delay then launch happens. GM has serviced it 3 times and the problems still exist but the shifting is now much more rough than before. The problem & risk continue today.
The contact owns a 2019 GMC Sierra 1500. The contact stated that the electrical system in the vehicle was defective which caused delays with several driver functions. He stated that the vehicle would restart while in operation after coming to a complete stop. The contact also stated that the vehicle hesitated and jerked while accelerating without warning. The contact stated that several attempts were needed while pushing the push to start button for the vehicle to start. The vehicle was taken to mc-elveen Buick GMC (117 farmington rd, summerville, SC 29483) on four separate occasion to be repaired however, the failure persisted. The manufacturer was notified of the failures and filed two cases for the failures. The vehicle was not repaired. The failure mileage was 900.
Transmission slipping turning corners at 5 mph, transmission slip take off at hill stop sign, transmission hard shift 2nd to 3rd gear intermitted and vibration 45 mph to 55 mph
2019 GMC Sierra shifts extremely hard when shifting from 1st to 2nd gear when accelerating after sitting idle for a long period of time. I took the vehicle to romain GMC in evansville, in and they stated that GM says this is how the transmission normally operates. This has the potential to be a safety issues as the engine goes into high revs and slams into gear, risking losing control of the vehicle, especially during icy or snowy conditions. This issue occurs daily, sometime multiple times a day.
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.
Vehicle with 8-speed transmission bucks or lurches when shifting up or down from first to second gear. Sometimes it feels like it is in a collision when this occurs. Dealer referred to bulletin #4605342 and said this was normal.
