Transmission shudders when starting off and slams into gear when down shifting. Took truck to dealer while still under warranty and was told that GM states this is "normal operation" and refused to perform repair under warranty. Now that truck is out of warranty period, GM is saying that transmission needs work at a cost of $6000 for torque converter and valve body assembly GM is well aware of the issues they are having with their Transmissions and refuses to fix or update..

Was driving and the engine died, lost power steering, lost gauges (No speedometer, No Tachometer, Gauges quite working at all) and lost power brakes. Had to try and pull over and was not able to stop or steer easily. I almost hit several other cars and a guardrail trying to stop and steer to emergency lane. After I got stopped, I was not able to restart my vehicle, the starter just kept running but the engine would not start and gauges didn't work. I had my vehicle towed home and started trying to figure out what happened. Put my code reader on the truck and it showed 12 different codes including ECM/BCM failure. I started checking fuses and relays but everything was good. Finally found the problem at the ECM. There was a wiring harness that was not secured and was rubbing against the frame of the truck. One little yellow wire had rubbed through and shorted out which killed the whole truck. It looks like the manufacturer didn't secure the wiring harness in several spots which allowed the wiring harness to rub on the frame and the mount that holds the ECM. The mount for the ECM has started to rub through a different wiring harness and had started rubbing through wires in that harness but I caught it in time.

- Memphis, TN, USA

When I started driving, the transmission began to feel loose, like gears weren-??t seated all the way. And then it began revving for no reason, and would eventually catch a gear as I let off the gas. I was driving with my kids and I was afraid that the gears would catch at a high rev rate and send me forward into other vehicles or pedestrians so I needed to end my drive asap. I was attempting to turn left at a light and the truck stopped going into any gear and I was stopped in the middle of the road. I had to push my car out of the way with the help of others.

- Stockton, CA, USA

While operating vehicle in stop and go traffic the transmission downshifts so hard that the rear end locks up. This abruptly stops the vehicle. This happens quite frequently. The vehicle has had multiple warranty "corrections" made to include a new torque converter and flywheel. The issue was not resolved. Appears to be no correction or applicable TSBS that fix the problem more of a bandaid. This is a wide known issue at this point.

The oil cooler lines on my 2019 Silverado 1500 disconnected at the crimp while I was driving. The vehicle has only a bit more than 30,000 miles. I checked online, I.e. various sites as well as nhtsa and found the GM Customer Satisfaction Program N192220080. In the pdf on your site dated June 22, 2021, it is stated that only 530 vehicles were affected. I believe that this problem is more widespread than GM is willing to admit. Fortunately I was not driving on the interstate at a high rate of speed where -?? a potential loss of propulsion-?? could have resulted in a tragic outcome.

- Lunenburg, MA, USA

Cracked Engine. There was no warning. No indications prior to incident. Driving approximately 45/50 mph on road, out of NO WHERE a message appeared "Shift into NEUTRAL and SHUT OFF ENGINE" I coasted to the side of the of road, there was no power at all. I did as the message stated. Once I turned off the vehicle, it would not start. It has not been able to start since that time. I had to have the vehicle towed. First to my local mechanic who could not find anything and suggested to take to a dealer, I had to have it towed again. Thankfully other vehicles behind me were patient enough for me to get to the side of road. However, this could have caused a very serious accident. I have read other complaints online regarding the same issue. GM/CHEVY states there are not enough complaints of the issue but have had some. Does a death need to occur to get attention" I certainly hope not. The vehicle has been properly maintained. Chevy can not give a reason for this happening. My vehicle is over the warranty amount in mileage. Therefore I have to pay 30% of the cost for a new engine. I would not be as upset if there was something I did, but if it is properly maintained, why" No one can answer that question. All I get is "I understand". If they did, they would have done something sooner and they would cover this cost 100%.There has to be some defect or issue somewhere. They can not seem to give me an exact figure for the repair. Who knows what my out of pocket cost will be.

Engine blew the lifters while driving on the highway at 75MPH in Morning traffic. The truck immediately lost power and dropped from 75 down to 45 quickly without any input from me. Luckily the cars behind me were able to swerve before hitting me while i was pulling to the side. The lifter failures are a known issue with GM trucks with the 5.3 and 6.2 liter engines. The service advisor told me they do at least 12 of these per month. There are 100's of messages on several forums where people have the exact same issue. Some of them experiencing the failures with as low as 5K miles. GM's fix is to replace both banks of lifter if the engine has under 16K miles and only replace the one bank if the engine has over 16K miles. The FIX is not really a Fix since GM is putting the same lifter design right back in, leading to many people having the issue multiple times.

When I put the vehicle in reverse the camera goes fuzzy then cuts out completely. Then goes on/off repeatedly. Also having transmission issues, I put the vehicle in drive and doesn-??t move until about 7 seconds after I let off the brake. Does a bad jerk! Shifting issue throughout the whole time I-??m driving! I talked to a guy about his truck that has the same issues I-??m having and he said the dealer needs to change the transmission soon. Really concerns me bc I feel like one day it will leave me stranded and the truck only has 48,000 miles

- Thibodaux , LA, USA

the truck is constantly running a shift to park message. It takes continuous attempts by pressing the brake and wiggling or changing gears to reverse, to drive back to park in order to shut off. Sometimes, it takes up to 10 minutes to stop erroring before I can exit the vehicle. this has started a couple years ago there has been no resolution by Chevrolet as to the reason or an option to fix it the truck will not allow me to leave and lock it while this is occuring so i have no option but to keep to shifting gears to make it stop.
