The power train delays shifting from 1st to 2nd gear resulting in hesitation in forward movement or a very hard, abrupt lurching forward shift. This happen on the first drive of the day and then intermittently throughout the day. Both types of shifts create unsafe conditions. It seems the engine power is linked to the the shifting issue and either not enough or too much power is applied at the shift point. In one instance the power train was confused and could not decide whether to be in 1st, 2nd or 3rd gear and shifted up and down while I was attempting to navigate congested city traffic at slow speed. GM service bulletin 20-na-102 and 16-na-361 suggest that the power train behavior is normal. When I returned the vehicle for service, this was the diagnosis. Discussion with the service advisor indicated that in some instances other actions are taken to address the situation, but it is never eliminated. Now customer satisfaction program N192272400 has been issued due to a faulty tcm which causes the wheels to lock up. This should be an urgent recall. These combined conditions create an unsafe vehicle that needs to be addressed and corrected.

My truck when it is in the city and I"M approaching a stop sign the transmission makes the vehicle shake. The aggressive shake only happens when I"M bringing my truck to a stop after going past the first gear. It can happen in the city and highway, but this only happens when the vehicle goes past the first gear and bringing the vehicle to a completer stop. I got the vehicle checked out and the dealer mechanic assumed the problem would get fixed after updating my truck from the recent break recall. But unfortunately the shaking when I put my truck to a stop still continues.

The transmission shifting from 1st to second gear has about a 5 second delay and then is a rough shift into 2nd. Only happens when the vehicle is cold from sitting for a long period like over night. After the one hard shift it doesn't do it the rest of the day. Done it since purchasing it in Sept 2019. It's like it lags after you wake it up and hasn't had its coffee yet. Does not matter if I back down my driveway first and then into drive. The first shift of 1st to 2nd has a lag and its rough into 2nd.

Rk purchased a 2019 Chevy Silverado lt 4X4 crew in 12/2019 right from the start noticed hard unsettling lunging in transmission while changing gears from reverse into drive.( hard jolt -lunging ) it would, at times jolt hard enough to slosh drink from cups into the cup holder/ or lap !. at approximately 2500 mile range the transmission actually ceased up, would not go in reverse nor drive. The engines RPM had shot up to 2500 -3000 RPM's and would barley crawl. Had it towed in to dealership. Reprogrammed the computer and stated that this should fix the issue, . but it didn't, still lunges and jolts pretty much each morning or at unsuspected times while shifting from revere into drive. Currently has 6200 miles now 4/2020.have contacted GM and received a case number that no one seems wanting to address at the GM -Chevrolet head quarters. Have called from 3/24/2020 until 4/9/2020 no live person has addressed (vm after vm)

Transmission shuttering at low speed causes vibration in the steering wheel on eight speed transmissions. Two visits to dealer. Transmission fluid changed, not change. Informed this is inherent in this transmission, just have to live with it. Does not shutter in manual mode. Read Florida has pending law suit filled. Very upsetting spend this kind of money for something GM should be able to either fix or replace transmission. Happens every time truck driven in (D) drive mode.

- Camden, DE, USA

Transmission will hesitate and shift very hard from 1st to 2nd gear especially in colder weather. This has happened since I purchased the truck. Dealer changed transmission fluid and said hard hesitant shift was normal.

I get into the vehicle while at my storage unit facility and within seconds turn the vehicle on by pressing the button on the dashboard. I immediately put the car in reverse. Three seconds after I am moving in reverse instrument panel starts flashing warning messages such as no speed over 62 mph, electronic brake systems something, service engine light came on and stayed on, and once again I was without brakes! I was not going fast, nor in traffic, but the fact remains I had no brakes, again! this issue was 'fixed' two months earlier in another recall for the brakes. This is not the first time I lost the ability to brake, but this will be the last time. This vehicle needs to be recalled in its entirety, I mean taken off the streets. It's not just the drivers of the truck who are in danger, other drivers, pedestrians, bicyclists are also in danger. A fatality is imminent but I ask the NHTSA how many fatalities before this dangerous vehicle is taken off the road? every safety device on this vehicle has been recalled: Airbags, seatbelt, and brake systems. This vehicle is not safe. The number of people who have lost the ability to brake are far greater than what is reported here. Please don't expect GM to fix this issue when they don't even know the cause behind the problem to begin with! first it was onstar, now it is the company they hired to create their computerized brakes. Computers having so much control over vehicles, I'm learning, is not safe. Please contact me for more information. I'm more than happy to share my terrifying experiences with anyone who can help my fellow americans and myself!

This problem occurs after the vehicle has been driven any distance, but far enough to shift gears in the automatic transmission and when the auto engine stop is deactivated manually or auto engine stop doesn't activate due to driving conditions. When the vehicle comes to a complete stop the torque converter locks and causes the vehicle to lurch forward. The problem is noticeable in traffic, but more of a concern while precision parking and when moving slowly without throttle or brake being applied. This has happened in my vehicle and in all similar loaner vehicles that the dealership has assigned to me during service. Specifically, when parking the vehicle and when inching forward to a complete stop without brake or throttle, the vehicle will suddenly lurch forward without warning and hit the sign, another car, or curb. This problem is not intermittent and happens during every drive and stop.

On Dec 16 I started my vehicle via the remote start. I then got in and my ecs, ABS, traction control, steering and a lot more lights light up on the dashboard. I went to back it up I couldnt stop it unless I stuck my foot in it hard and I couldnt even steer it so I wouldnt wreck. Called onstar they said to drive carefully but needs to be serviced within 7days. I parked it found another way to work and had my vehicle towed to the dealership. They said it was fixed and was just a battery issues and they fixed a couple of recalls. Then on Jan 26 not even a month later I was at the grocery store and started the truck, started backing up and the dashboard started lighting warnings and I couldnt get the truck to stop. Finally with everything I had I got it to stop. I had to get the vehicle home cause it was Sunday so I put on my flashers drove less than 30mph and got it home thank goodness without causing a wreck. Had it towed back to another dealer and you know this dealer blamed the other dealer said they didnt do something right and they just reset the system. A week later, and again having it towed with my own insurance cause onstar wouldnt tow it to the dealer I wanted. I wasnt even offered a loaner vehicle.

When I was driving this vehicle first problem I start getting was the 4WD service light and won't be able to switch to 4WD, and was. Close to get in the wreck couple time during the winter storm. Second problem was when I was driving around 70mph on hwy truck got reduced engine power and slowed down my speed a lot, luckily I didn't have vehicle to close to me. Another problem I had was transmission issues, I was driving 25mph and my vehicle got blocked instant and won't move forward. Imagine if this happened on hwy driving 70mph and vehicle to stop/block the wheels and someone to be behind could be a big wreck. And after that issues truck won't go forward anymore, just on reverse

Vehicle shifts harshly making control questionable at times. I went to accelerate around a vehicle lost all power until it found a gear. Someone will get hurt because of this truck especially on slippery winter roads. Been to the dealership 3 times no fix. Please help

- Edgerton, WI, USA

Every morning since vehicle was new has 2600 on it now when cold I pull out onto street when vehicle shifts from first to second gear the shift shift slips and flares like it S in neutral and vehicle will hesitate slow down while it's waiting to get into second gear, this is a safety issue because their is no forward movement during this and possibly could cause an accident because vehicle won't move quick enough, after shift 2-3 is perfect and 3-4 will do same thing slip and flare, I've been told this is normal but I am a automotive tech and have been for over thirty years there is definitely something wrong with trans but GM won't admit problem this is wide spread as there are the same other complaints on this website.

- Sudbury, MA, USA

Seemed as if the car would almost slip in and out gear when diving approx. 30-40 mph. I then noticed the check engine light came on and flashed engine reduction and seemed to lose some power. I took it in to the dealer, 2 days later they replaced R&R camshaft position actuator magnet intake.the next day after the truck back. I started the truck it put it in reverse and the engine stopped running but it seemed as if it the engine was still running as when you use the remote to start the truck, after the 4th try the truck stayed running but the engine reduction warning had lit up again. The truck has been back at the dealers for 6 days trying to figure out the problem

When putting vehicle in drive from park it jumps forward even with foot on the brake. When going from reverse to drive it feels like the vehicle is not in gear and then engages and then the vehicle makes a clunk noise and abruptly jumps forward. There is also a issue when going from first to second when accelerating and the same when downshifting. The transmission on this vehicle is very erratic in nature, you never know what it is going to do every time you drive it. This has been happening since the first 100 miles and I now have 8600 and still happening. I have taken it to the dealer and they stated they could not get it to repeat the issue even after letting it sit outside in 20 degree weather to cool everything down.
