POWER TRAIN
Transmission issues such as vibration/grinding, delayed shifting, rough shifting, clunking noises when changing gears, jerking sensations, vehicle is available for inspection. The transmission control valve may fail, causing the rear wheels to lock up. Transmission was inspected, Dealer claimed Torque converter issue and replaced that part, however, ISSUE still exists and Dealer claims that at the 2nd inspection, it was the tires giving me the rough shifting and vibration/griding I feel when driving. No warning messages, just continued vibration that turned into grinding at it continues to get worse. Issue started at 55K miles, truck currently has 60K miles, torque converter was replaced at 58K miles. The issues seems to be the same as the current GMC Diesel transmission recall. This recall SHOULD pertain the Gas Transmissions for the same year vehicles.

While towing my 5th wheel rv trailer, the rear wheels locked up numerous times while at highway speeds(60-70mph). Hope our didn't cause any internal/ structural damage to my trailer. Scheduled a service with the dealer(Gamblins Chevrolet, Enumclaw, WA) for them to diagnose. The dealer found no issue or cause. Left the dealer for the same thing to occur the following week. Brought back to the dealer for this issue and others to determine the torque converter had failed, dealer replaced converter, at a later date rear wheels locked up at highway speeds again. Been ongoing with no solution.

My truck has less than 50,000 miles on it and the transmission feels has if it's shifting hard and shuttering during the cycles of first to third. I do not see that my truck has a recall, but if there is a problem with my trucks transmission, then I need to have it looked at before the 60, 000 or 5 year warranty expires. Can I just take it to a Chevy dealership and have this inspected at NO CHARGE to me?

#N232426400-04: Safety Recall - Tailgate May Open Unexpectedly lists RPO code QT5 as the only applicable RPO code for the issue of tailgate opening unexpectedly. QT5 is for manual gate function with EZ lift, power lock release. The recall blames water intrusion into these vehicles’ tailgates that can come into contact with the electronic gate-release switch, potentially causing a short circuit, which may inadvertently unlatch and open the tailgate when in park. The correction is to replace the exterior touchpad switch assembly with part number 85734717. My vehicle has RPO code QT6, which is for power up/down gate function with power lock and release. That option uses the same exterior touchpad switch assembly with part number 85734717. My vehicle did exhibit the same problem of opening unexpectedly while in park. That exterior touchpad switch eventually stopped opening or closing the tailgate altogether, and occasionally the tailgate would get stuck in the closed position while a dash message would say it is open. When it was immobilized in the closed position neither the exterior switch, the interior switch, or the key fob would make the tailgate open. It's my opinion that my vehicle experienced the same root problem as is described in the recall with the exterior switch assembly short circuiting, and that RPO code QT6 units should be included in the recall.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Vehicle attempted to do an 'over the air' update to the infotainment system. This prompted an error message, stating the update failed and return to the dealership. Took vehicle to GM dealer, diagnostics were run, and dealer stated that an update was not available, and the module for the infotainment system was bad. Quoted me $1600 for replacement and install. Have read multiple reports with owners' having the same issue. Infotainment system attempts to do an update, and it fails. The owners are left paying out of pocket for something that was not their fault. This needs to be a recall. Not only are you paying a hefty amount for a repair that is not your fault, but the entire Infotainment system doesn't not work (stereo, cooling/heating info, back up camera etc)

ENGINE
While driving down the highway on 11/03/2024, the engine warning light started to flash, I heard a clicking & Clanging noise so I pulled over as soon as I could find a safe place. Turned the ignition off & on again & engine warning light did not come back on, but still heard noises coming from engine. When driving home, the engine warning light came on again. I stopped again & turned the ignition off. When I turned it on again, the warning light quit flashing. I drove to the local GM dealer the next day, and they said it was a lifter problem. I did some research and found there were many lifter problems for a 2021 Silverado that I owned. I was hoping the dealer would replace both sides of lifters as they told me there was an issue & they were reengineered. Service department employee said they could only replace one side as that was all GM would approve. I told the employee that I did some research & there was a bulletin that said if mileage was less than 16,000 miles, both sides should be replaced. The employee said you surely have more miles than that & I showed her my odometer reading of 14,528. Again the employee told me that was all that GM would approve. I believe this is a safety issue if there is not a safe place to pull over. Also there should be a recall to replace these lifters with the reengineered lifters or extended warranty so us consumers are not stuck with a huge bill in the future as GM is aware this is a chronic problem.

ELECTRICAL SYSTEM
The tailgate activates on its own, whether the truck is on or off, in motion or parked, the tailgate will activate and open at random times. There is no button that is pressed down, and no user error making this happen. When driving the vehicle, the tailgate will slam open and if you are pulling a trailer, the tailgate will slam into the trailer hitch and cause damage. Also, contents falling out of a truck bed is also a serious concern for other drivers. The truck was read for codes, and the code U0140 came up for the body control module that is malfunctioning. The truck has not been inspected by the manufacturer as of yet, but if need be, it can be arranged. The first time this error was noticed was in August 2024, and has been happening on & off since then. There were no dashboard lights on showing an issue was present when it first started and even now there are still no warning lights. Please consider issuing a recall, this is a major safety issue for other drivers.

STEERING
When I started my car there was an error message that said "Service Power Steering Drive with Care" and "Service ESC" when I went to back out of the driveway I had no power steering at all. I could barely move the wheel and had trouble pulling back into the driveway. I turned off the car and restarted a few times, but received the same error messages and had no power steering. When I started the car about an hour later all error messages went away and power steering was restored, but I am afraid to drive it.
