What owners say
Purchased a used 2021GMC SIERRA in Mar. 2025 from W&K GMC Sedalia Mo. Two mths ago ([XXX]) noticed an occasional slipping in transmission, wheels lock up. The truck would slip, lock for 1-4 seconds and then return back to normal driving. Has done this while accelorating and while driving down the highway. I took truck to my local repair garage who indicated it was most likely the torque converter and it would need to be taken to the dealership for repair. After mechanic commenting that he had seen several GMCs with the same problem, I looked up GMC recall and found that this issue did have a recall on 2020 - 2022 GMC SIERRA TRUCKS ( ours is a 2021)! When my VIN did NOT show any recalls, I called W& K GMC in Sedalia on 9-23-26 and spoke with the shop who told me MY truck did not have the recall notice and it would cost me $160 out of pocket for a diagnostics and $600 -$800 for a converter to even be flushed to see if problem resolved PRIOR to any part replacement. They would have to charge me full price for this repair since MY VIN DID NOT HAVE A RECALL, BUT THE SAME TRUCK MODEL, YEAR, AND ENGINE HAS OTHER RECALLS? I called GMC customer service line on 9-23-26, spoke with customer service agent Tanika, she documented the same info. and could not explain why a 2021 Sierra with the same problem as a 2020-2022 Sierra was not included in this recall that it must have been manufactured in a different facility? The fact that my local garage mechanic in a very small town, has already seen SEVERAL GMC trucks with the SAME PROBLEM, leads me to believe this is a WIDE SPREAD PROBLEM, that GMC is choosing to ignore due to the cost of repairs involved. I am requesting an investigation into HOW MANY RECALLS HAS GMC SENT OUT AND REPAIRED? AND SPECIFICALLY WHY AFTER 3 YRS OF PRODUCTION BY GMC DO THEY BELIEVE A TRANSMISSION PROBLEM WAS ONLY CERTAIN VEHICLES AND NOT ALL THE VEHICLES? This is a huge safety concern if wheels lock up on hwy at 70mph due to malfunctioning TC INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I

The contact stated that while at a red traffic light, the vehicle accelerated unintendedly, and the vehicle shuddered with an abnormal dinging sound coming from the vehicle. The message "Transmission Hot - Idle Engine" was displayed on the instrument panel.

The manufacturer was notified of the failure and referred the contact to the federal safety agency Hotline to report the failure. The failure mileage was approximately 126,098.
transmission shift hard and slipping. When step on gas to go faster transmission shifts really hard like going drop on ground. Sometimes wont shift at all only goes up to 69 till left off gas and then transmission will shift. Start happening with about 10000 miles on truck and GMC said this is normal. Now need a torque converter and shift module in it.
The vehicle suffers from a persistent transmission defect including shuttering bucking slipping torque converter failure valve body failure twice metal debris improper down shifting chirping noises and related liability and safety issues. The vehicle has undergone multiple unsuccessful repair attempts at authorise GM dealerships. These repairs include torque converter replacement valve body replacement twice solenoid replacement fluid services software updates. The transmission problems have persisted despite these efforts and the vehicle has been out of service for more than 22 business days including a breakdown driving to Florida. I have filed a claim through GM but it seems like it just keeps getting pushed further and further away this is a serious safety issue as I fear for those driving around me and myself that I may cause an accident with the bucking slipping and failure to operate properly on the road.
The engine had a critical failure at 49,000 miles. It was replaced under the drivetrain warranty. That came with a 12 Month, 12,000 mile warranty. Now I have a SECOND engine failure at 59,000 Miles. This will come with only a 12 month 12,000 mile warranty because it is NOT under recall. ALSO my transmission is now slipping and they are replacing the Valve Body. They had my truck for 4 months the first time and one month this time. These are the exact same issues with 2021 - 2025 GMC 6.2L and 10 Speed Transmissions. If I the issue had happened 6 months later I would have NO warranty. I want a recall on 2020's please.
Check engine light illuminated with service transmission. The next day transmission started slipping and finally would not engage in reverse. Dealership Has it now and after diagnosis they advised that they had replaced the electronic control module to which, on the test drive, the gauge cluster blacked out and they got more codes. The cpdes that the vehical threw were the transmission valve body needed to be replaced.The truck has 24k miles on it.
Shuddering, slipping, then lost all gears. Unable to put in reverse, drive, or low. Repair shop says the transmission needs replacement. Pump and torque converter issues. Vehicle has excellent maintenance and only 84k miles.
This is in addition to the first report regarding my 2022 GMC Sierra SLT with 10-Speed Transmission. I had previously filed a complaint (NHSTA Tracking# 11728418.) regarding the OnStar and Internet quitting on me. Which was the Serial Gateway Module. I had reported that I was put off many times regarding a loner vehicle so i could get back and forth to my Oncologist for treatment of Head and Neck Cancer. And years of follow-up appt. with specialists Gastrointerologists and Cardiologist for serious issues incurred from 168 intense radiation treatments and Chemo. I had also taken my truck in for all scheduled maintenace intervals specified by the dealer and the manufacturer. "REPAIR ORDER GCCS504610" I had to leave it in the shop for 30 days for a defective Exhaust System, Radio, Charging Port, Remote Key Fob not able to unlock the truck so i could get in. And some other warranty/recall issues regarding my A/C blower and Seat cushion blower motor and Trailer Brake Switch, Fog Lamps running while daytime running lights were on - All Safety issues, My truck was @ Beck & Masten GMC for 30 days during these repairs, recalls and warranty. Will attach INVOICE 123532 to show consistant sheduled maintenance per GMC guidelines. Waited while this service was performed. "REPAIR ORDER / INVOICE 140542" Again my truck was back at Beck & Masten GMC (19 days) for the Serial Gateway Module and Radio not working AGAIN! Again, no OnStar, No Internet, No GPS. And, I reported the oil consumption and Add OIL light coming on; which was dismissed as idling too often (. I had to add 2 qts of oil between scheduled oil changes(The truck had only 13754 miles at this time) The LAST time I had anything to do with Beck & Masten GMC South was when I spent over months waiting on a loaner vehicle because I needed them to please look into still having an oil light coming on. And slipping and front end wobble just before the slipping/clucking and high RPM's that were dangerous- accident!!
