6 months and 20,000 miles after purchasing the 2021 Chevy Silverado custom 4x4 with the 8 automatic transmission and the 2.7L turbo charged engine with 32,000 original miles on it from Volume Chevrolet in Forsyth GA I noticed the transmission was jerking when the truck was first crunk and warming up after about 10 minutes and once it got to 8 mph after a while when the temperature gauge was half way up it would stop and when you slowed down from 55 mph to about 5 MPH to make a turn it would suddenly jerk again, I reported the issue to the dealership service mechanic shop reps during every oil change and they assured me that it was normal and that it would stop happening when I let the truck warm up for about 30 minutes prior to driving, once the factory power train warranty ran out, they informed me that it needed a transmission service and they would have to keep it a few days and it would cost around $800 or so to get it done, the purge pump on the emissions system has a factory defect and I received a recall letter about it 6 months after purchase and they are refusing to replace the purge pump until they perform a full diagnostic first even though they have done a scan diagnostic and it shows the purge pump failed and I have just been struggling with all the cost of living and increased prices I can't afford any kind of costly repairs right now and my truck now has 120,350 miles on it and the issue is getting worse to the point that I am sure that the transmission valve body and some other sensors and control modules are failing, this is not a single issue and other dealerships have said that the transmission was starting to have problems in other trucks at around 55,000 miles and some earlier than 55,000 miles, I believe that this is an ongoing transmission issue with the 2.7L turbo charged engine in both the 4x4 and 2x4 models and with the 8 speed automatic transmission In general, I have talked with several other owners and they have had similar issues.

Component is transmission. Stutter vibrate shift while driving. There is a recall on the 2021 Chevy 1500 Silverado which is exactly the issue we are having from our 2021 Silverado. The VIN for our truck is falling under the current recall. Chevy wants to charge to even diagnose the problem which has to be done with a dealer and not a private place. That is absurd and puts our safety at risk should the vehicle stop functioning while driving it. The dealer ship has inspected the vehicle for the yearly inspections which is interesting since this has happened and been complained about since purchase.

I was stopped at a stop light and all of a sudden, the engine just revved amd revved and no drive only reverse, and it happened 4 times until tonight, 11/11/25 @ 8:38pm I am stuck at another red light and have to back my truck up to Home Depot and get a tow. Only a 5 year old truck with 71122 miles and ALWAYS WELL MAINTAINED WITH PAPERS AND GOES OUT ON ME. NOT ACCEPTABLE GM! You make things and used to be solid, like a rock trucks but now I feel robbed as a long time Chevy fan/enthusiast but I may have to change manufacturers unfortunately.

The truck started to vibrate badly. Brought it to the dealership and have to replace the 6.2 L engine. I was happy to make it home without it breaking down. The truck only has 67,000 miles on it.

- Durango, CO, USA

My transmission started to make a rumbling sound intermittently while I was on the highway. It happened during normal highway speed and not dependent on acceleration or deceleration. I brought it to the dealership with 84,000 miles and they dropped the transmission pan. No metal found in the fluid. The issue was with the torque converter. I had my oil changed 1.5 weeks prior with a 21 point inspection. I was curious if there was a TSB for this issue. I haven't been able to find a recall notice for this issue.

I experienced a locking up or no power to the rear wheels. It was raining and the rear wheels would spin. I had no traction. I had to take a few turns and had to be careful or I would have fishtailed into other vehicles. When I stopped at a stop light/or sign then proceeded forward the rear wheels would spin in place. The tires wouldn't grab the pavement. This is the best way I could explain it.

While driving the engine shut off without any warning lights which could have caused a serious accident causing bodily harm or property damages as I was unaware of the issue and was going 50mph at the time - this occurred on 10/23 I noticed a ticking and brought the vehicle to the dealer for inspection on 10/20, at the time of this inspection the technician said that they could not replicate the sound and I explained that this was happening at 3000 RPM. The technician said that I would need to bring the vehicle back and they would need to start to take apart my engine piece by piece and I said the ticking is part of the known lifter problem and the technician shrugged his shoulders offering no other options. That same day I took my vehicle to another independent shop and he confirmed the ticking is a known issue that occurs prior to the lifter collapsing. After the vehicle shut itself off, and I was able to restart the vehicle, many warning lights appeared on my dash, there were none there before, one of the codes that was flashing was ESC and the vehicle began to lurch and downshift. I called my mechanic who said the code was to do with the electronic stability control system but I should be okay to drive until I could get to him for him to look at the codes. On 10/24 I took the vehicle to the mechanic and another code was for Cylinder 3 misfire which he stated could be the collapse of the lifter and the codes will not clear. The vehicle now downshifts without warning, there is an engine knocking that is occurring and the vehicle is not safe to drive as the engine may seize at any moment.

Vehicle has started shuddering everytime i drive, normal speeds, flat roads, hills, everything. Feels like my rear end disengages and re-engages while driving. Afraid it is going to lock up completely or im going to lose all power. Dont understand why my vehicle isnt included in the recall already out for this issue.

Truck shudders when you try to maintain speed. The service engine light is on all the time. RPMs bounce up and down constantly. GMC dealership said it needs a new torque converter. It was $100 just to diagnose it!

Truck has under 45k miles on it. After reaching 35-40mph, it began to shake and jolt. Once we drove approximately 20miles, the engine light began flashing, in addition to the parking break light turning on. The truck began to lose power and we were forced to pull over on the side of a busy road. After waiting a little bit, we were able to drive it to our local shop who advised us to tow it back the the dealership for repairs.
