Vehicle is a 2021 Chevrolet Tahoe Premier with under 50,000 miles. The vehicle experienced a sudden and complete loss of reverse gear, accompanied by violent lurching, sputtering, and dangerous hesitation/stuttering while accelerating between gears at speed. A certified dealership inspection physically diagnosed the vehicle with multiple stuck valves inside the transmission control valve body, requiring a complete valve body replacement. This exact mechanical failure completely mirrors the known safety defects outlined in GM Special Coverage Program N242454441, which details transmission pressure losses causing gear engagement conflicts and potential rear-wheel lock-up hazards. The replacement transmission component installed by the certified dealer failed catastrophically within four miles of pickup, again causing severe transmission sputtering and shifting failures that render the vehicle entirely unroadworthy and a safety hazard on public roads. The dealership has been forced to order an entirely new replacement valve body assembly under warranty due to a consecutive failure. General Motors Corporate Customer Assistance acknowledged that the vehicle is physically experiencing this transmission valve defect, but refused a voluntary warranty override solely because the vehicle's automated database VIN block falls just outside their pre-programmed list for Special Coverage N242454441. The corporate case representative explicitly instructed the consumer to file this federal safety report with the federal safety agency due to the systemic component failure.

While driving the vehicle at highway speeds the vehicle starts to lurch or randomly lose power. Eventually, within a few minutes, the lurching gets worse and the check engine light starts flashing. In a GM vehicle, a flashing check engine light is critical engine failure. After pulling the vehicle to the side of the road, the check engine light stops flashing and stays on constantly. After about 10-15 minutes, the check engine light turns off completely. The GM dealership can read the history and says it's P0300 error code for General Engine Misfire in cylinder #6. GM warranty refuses to fix anything because the light isn't on when the car comes into the dealership. The car has been to two different dealerships, with both of them telling me it has the same error code. GM customer service told me without the check engine light being on when the vehicle is brought into the dealership, they would not be able to help me. This is being told to me even though everyone agrees that the check engine light has been on. I was told by GM to continue to drive the vehicle. It has been into the shop 4 times since January for the same issue. This is not safe as the engine has suffered a critical issue. I don't feel safe driving the vehicle. My GM Customer Service case is 110460594.

Rear wheels suddenly lock up momentarily during downshift at 30-50 mph (most reproducible 35-40). Transmission in a high gear (8th-10th); any throttle input commanding a downshift can trigger it: as the downshift executes, rear wheels briefly stop, skid with an audible chirp, vehicle jerks violently. Reproducible on demand, multiple times per drive, on video. Highest-speed event ~50 mph, family aboard. NO advance warning: no check engine light, no message, no stored code, no gradual onset. Traction control sometimes activates at the instant of the skid, sometimes not — always reacting to traction already lost, never before. A driver has no opportunity to anticipate or react. THIS IS A LOSS-OF-CONTROL HAZARD. It is especially dangerous in a turn, on wet pavement, or in traffic. Onset May 2026. Pursued repair since, across three shops: an independent, twice (no codes/leaks/abnormal findings; MAF replaced; unresolved; referred to dealer), then a GM dealer 3 days (test drove 34+ miles, no codes, fluid good, all shifts correct; declined recommended control-module recalibration, cause unconfirmed). Lockup recurred within 5 miles of leaving, same day; I returned immediately, asked for a tech ride-along while fresh — did not occur. Next day, a second GM dealer: tech note said fluid was low, though the same RO's inspection passed that fluid and found no leak; no leak ever identified anywhere. Paid $672 for a fluid exchange — unresolved. Days later, same dealer measured 265F on a 30-mile road test and condemned the transmission. Full replacement underway, largely out of pocket. Symptom matches recall 26V‑085 (momentary rear wheel lockup, worn control valve, 10-speed/ETRS) covering 2022 models. My 2023 is not included. I am not asserting a diagnosis — no one has established the cause — but I ask ODI to consider whether that campaign should include additional model years. The failed transmission is available for inspection; videos available on request.

After driving the vehicle for 5000 miles, the check engine light appeared. We brought the vehicle to dealership and were told that a cylinder was mistimed. They replaced a bank of lifters and returned the vehicle to us. A few weeks later, the check engine light reappeared and we noticed the engine was making some odd sounds. It wa brought back to the dealership and they replaced the fuel pump and hose. The vehicle was returned to us but the check engine light reappeared. The dealership stated that they couldn’t reproduce the problem after testing. The vehicle was returned to us but we noticed that it would periodically lose power upon driving and would have lurching sensation while driving. The check engine light came on intermittently and it is now being brought back to them for the fourth time.

Chevrolet has a recall on some vehicles for a bad transmission valve body, but my vehicle isn’t a part of the recall and I’m having the exact same issues. Currently my only vehicle that I have to transport my 7 month old is a complete safety risk. My check engine light is on and the code its throwing is to replace transmission valve body assembly. My Tahoe is shifting very harshly when driving normally, it feels like it slams into gears causing the whole car to jerk. When sitting at a red light that turns green, Tahoe is slipping, barely wanting to move through an intersection with vehicles all around me. I’ve been advised to not drive my Tahoe at all because if I do I will certainly have severe drivetrain damage and rear wheel lock up. Like I said, Chevrolet already has a recall for this issue on some of their vehicles, but my specific Tahoe does not. This is my only vehicle for myself and my baby and I cannot drive it due to its safety issues.

My 2017 Chevrolet Tahoe equipped with a 6L80 transmission began experiencing transmission-related drivability issues at approximately 130,000 miles. The vehicle jerked on takeoff, had delayed/slow shifting, produced a whining noise, and later had intermittent shuddering/surging while driving. During service, metallic debris/shavings were found in the transmission fluid. The transmission ultimately required replacement at my expense. I am aware of GM Technical Service Bulletin 20-NA-142, “Shudder/Surging While Driving,” which includes 2015–2022 Chevrolet Tahoe models equipped with MYC/MYD transmissions and discusses conditions that may be identified as torque converter shudder. My vehicle’s 6L80 transmission corresponds with GM RPO MYC, and the symptoms/repair findings appeared consistent with the bulletin. I am filing this complaint to document the transmission failure and related safety concern, as the jerking, delayed shifting, and shuddering affected normal vehicle operation.

My vehicle started having stuttering/shifting issues back in August 2025, I was advised the vehicle did not need new engine but upgraded oil. I continued to have the issues and have continued to bring back to dealer for constant software updates - cannot duplicate issue meanwhile the stop sale order was issued and I was not advised. The vehicle then experienced very hard jerking- stall- that lead to the dealership putting an AWD IN 2WD calling it a fix! Just got vehicle back again after a complete stall at a stop sign- causing vehicle to roll back and cut back on! Dealer stated the vehicle showed the stall/shutter but could not duplicate on road test. This is a serious safety issue!!

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while driving at 75 MPH, the vehicle shut off without warning. Due to the failure, the contact used excessive force to steer the vehicle off to the shoulder of the highway where the vehicle was then towed to a dealer. After the vehicle remained in the dealer's possession for over a week, the vehicle was diagnosed with an engine failure. The contact was then informed that the vehicle was placed under recall the federal safety agency Campaign Number: 25V274000 (Engine) and that the engine would be replaced. Despite the engine repair, the contact stated that an abnormal, rattling sound would emit from the vehicle upon start of the engine. In addition, the contact stated that the vehicle would violently jerk upon depression of the accelerator pedal while at a complete stop. The failure started intermittently; however, the contact stated that overtime the failure became more persistent. The vehicle was taken to the dealer where they claimed that the transmission was four quarts low on transmission fluid; they then informed the contact that they could not guarantee that remedy would repair the failure. The contact stated that failure improved; however, she would still experience a slight hesitation upon depression of the accelerator pedal. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 39,000.
