2023 Chevrolet Tahoe: jerking or lurching

Filed Jul 21, 2026 · Transmission · NC

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.

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.

At less than 50,000 miles, my alternator went out and had to be replaced, causing the battery to need to be replaced also. Now, at only 51,000 miles, my transmission is having problems and causing the vehicle to jerk when shifting. This vehicle has had regular maintenance performed by a combination of dealers and certified service centers since it was purchased brand new. I have never had this much trouble with a vehicle and am very concerned about it's overall safety and integrity, given the severity of the problems for something that is not old and does not have high mileage.

Transmission issue. Vehicle has the Duramax Diesel with 10-speed transmission. I am aware of issues with earlier year/s transmissions. I have experienced shuddering, jerking, a SINGLE momentary rear axle lockup. Jerky engagement from drive to reverse and or back. Reduced Acceleration warning on display. Check engine light comes and goes. Waiting for dealer to further inspect, drain fluid, etc. It appears from the VIN check that this vehicle had some metal work/paint prior to delivery to selling dealer, paint does not match. The transmission issue at 15,000 miles is just plain scary and not what one expects. That this vehicle sold as a 2023 has same issues as earlier model years makes me wonder if this is in fact a late 2022 model with the known defective transmission valve body? Any help appreciated.

Feels like the transmission is slipping. When I step on the gas it makes a jerking/ tugging motion like its pulling backwards and feels as though it has no power. It’s gotten progressively worse now over 10k miles and I should not have any engine problems with a new car. This happens every time I drive it. The problem is not fixing itself it’s getting worse by the day.
