Chevrolet Power Train Recalls Cover Drive Loss and Wheel Lockup
⚠ 1 of these recalls carries a do-not-drive advisory.
Loss of drive power recurs across Chevrolet’s listed power train notices, involving transmission leaks, separating shafts, and missing retaining components. Equinox and Traverse appear repeatedly, including certain 2018–2020 vehicles in the accumulator-bolt recall. Certain 2020–2021 Traverse wheelchair conversions have a separate transmission-contact defect. The 2023 Blazer and Traverse appear in separate retaining-ring and sun-gear notices. Silverado trucks recur in driveshaft and diesel transmission-control-valve recalls, while Tahoe and Suburban appear in driveshaft, diesel transmission, and transfer-case notices. The May 2026 transfer-case notice covers specified 2026 vehicles and certain 2015–2020 SUVs and explicitly instructs owners not to drive until the remedy is completed.
Warning signs to watch for
- October 29, 2020, accumulator-bolt recall: transmission oil may leak and progress to loss of propulsion.
- January 27, 2022, Tahoe and Suburban driveshaft recall: driveshaft failure may cause sudden loss of drive power.
- February 2 and March 16, 2023, Blazer and Traverse recalls: shaft separation or disengagement may cause drive-power loss or rollaway in Park.
- November 7, 2024, Express transmission recall: harsh shifting, reduced power, unintended deceleration, rear-wheel lockup, or movement in an unintended direction may occur.
- May 7, 2026, transfer-case recall: front and/or rear wheels may lock up without warning.
Can you keep driving? What the notices say
One supplied notice carries a stop-driving instruction: the May 7, 2026, Chevrolet Tahoe, GMC Yukon Wheels Can Lock Up transfer-case recall. It advises owners not to drive their vehicle until the remedy is completed. None of the supplied power train notices carries a park-outside instruction. The remaining listed notices, covering transmission leaks, driveshafts, axle shafts, half-shafts, sun gears, diesel transmission control valves, and Express transmission software, do not tell owners to stop driving.
What the free repair involves
The listed remedies are free. Dealers inspect the accumulator and replace it if bolts are missing; Braun replaces the Traverse screw and clip and inspects for transmission contact. Shaft recalls specify their respective shaft replacements; the sun-gear recall replaces sun gears. Diesel and Express recalls receive specified transmission software updates. The May 2026 recall requires transfer-case inspection and replacement if necessary.

Common questions
Which Chevrolet power train notice says to stop driving?
The May 7, 2026, transfer-case recall instructs owners not to drive until the remedy is completed. It covers specified 2026 vehicles and certain 2015–2020 SUVs. Dealers inspect the transfer case assembly and replace it if necessary, free of charge.
Why do two 2023 Blazer and Traverse notices mention rollaway?
The February 2023 notice describes missing left-side half-shaft retaining rings and specifies half-shaft replacement. The March 2023 notice describes an incorrect transmission sun gear and specifies sun-gear replacement. Each describes possible drive-power loss or rollaway when placed in Park; both remedies are free.
What repairs address Chevrolet transmission-related rear-wheel lockup?
The October 2024 diesel notice specifies new transmission control module software and special coverage for transmission repairs identified by that software. The November 2024 notice for certain 2022–2023 Express vehicles specifies a transmission control module calibration update. Both software remedies are free.
