Overview
General Motors has expanded its 10-speed automatic transmission recall to include additional 2022 full-size SUVs with Electronic Transmission Range Select (ETRS) and is separately directing a group of truck owners back to dealerships after an incorrect software version was installed during prior recall service.
Key points
- 43,732 more SUVs added: certain 2022 Chevrolet Tahoe/Suburban, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV models equipped with ETRS (shift-by-wire).
- 1,055 trucks need a re-do: some 2020 Silverado/Sierra 2500–3500 and 2020–2022 Silverado/Sierra 1500 received the wrong transmission software during the recall.
- Issue centers on faulty valve bodies that can cause erratic or unsafe shifts; software aims to detect early symptoms and trigger a protective “limp mode” to reduce risk, but it does not repair the hardware.
Which vehicles are affected
- SUVs (newly added): 2022 Chevrolet Tahoe and Suburban; GMC Yukon and Yukon XL; Cadillac Escalade and Escalade ESV — only those with ETRS. The feature was not standard on all trims.
- Trucks (software reprogramming correction): 2020 Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500; 2020–2022 Chevrolet Silverado 1500 and GMC Sierra 1500 that previously received an incorrect calibration.
What’s going on technically
The recall targets valve bodies that manage hydraulic control of gear changes within GM’s 10-speed automatics. Failures can lead to uncommanded or unsafe shifts and potential rear-wheel lockup. GM’s software update monitors for early fault indicators and limits transmission operation if detected to prevent dangerous events. If the wrong software is installed, those safeguards may not trigger correctly. The software is a mitigation, not a mechanical fix.
Why ETRS matters in this expansion
The latest SUV additions share ETRS, GM’s shift-by-wire interface, which can change how transmission and vehicle control modules interact. The Drive reports that ETRS was typically fitted to higher-end trims and certain 4WD configurations, so this wave primarily impacts upmarket 2022 SUVs.
What owners should do
- If you own a 2022 GM full-size SUV with ETRS, watch for recall notices and schedule dealer service for the preventive software reflash and any necessary component replacement.
- If you own one of the 1,055 affected trucks, return to the dealer to have the correct transmission software installed so the system can properly detect valve body faults and enter protective mode.
- Be aware that if safeguards engage, you may experience reduced performance or limited shifting until a permanent repair is completed.
Broader context
According to The Drive, GM has broadened this campaign in stages over roughly five years across much of its rear-wheel-drive portfolio. The publication also notes GM recently released an updated valve body for light-duty 10-speed units that it hopes will be a lasting fix, though its fleet-wide effectiveness remains uncertain. Early 2026 marks a new phase with the ETRS-focused SUV expansion and the targeted software reprogramming for certain trucks.
