General Motors has issued a recall affecting 43,732 full-size SUVs from the 2022 model year due to a potential transmission defect. The issue involves the 10-SPEED automatic gearbox, where excessive wear in a control valve could lead to rear wheel lock-up. The recall impacts several popular models sold globally, including in the Middle East, where large SUVs remain highly popular among families and fleet operators.
Affected Models & Production Year
The recall includes the Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, GMC Yukon XL, Cadillac Escalade, and Cadillac Escalade ESV from the 2022 model year. Both short-wheelbase and long-wheelbase versions are affected. These SUVs are widely sold in markets such as the UAE and Saudi Arabia, making this recall relevant to regional owners.
Transmission Issue Explained
According to safety documents, the problem stems from excessive wear in the transmission control valve within the 10-SPEED automatic transmission. This wear can cause fluid leakage and pressure loss. As a result, internal valves may move unexpectedly, leading to harsh shifting and, in rare cases, rear wheel lock-up during downshifts from eighth gear.
Potential Safety Risk
If the rear wheels lock up, it can increase the risk of a crash. The lock-up may be momentary or, in extreme situations, permanent. Sudden wheel lock during driving can compromise vehicle stability, especially at highway speeds. Given the size and weight of these SUVs, the safety risk is considered serious.
Dealer Fix & Software Update
To resolve the issue, dealers will install updated Transmission Control Module software. The new programming will monitor valve performance and detect excessive wear roughly 10,000 MILES before a potential lock-up could occur. If wear is detected, the system will limit the transmission to fifth gear and display a service engine warning with a reduced propulsion message.
Middle East Owner Advisory
Owners in the Middle East who have imported 2022-model-year units or purchased through official dealers should verify their Vehicle Identification Number with local distributors. While newer 2023 and later models already include updated monitoring software, affected 2022 vehicles should be inspected promptly to ensure safety and reliability.
Conclusion
The GM recall highlights the importance of proactive software monitoring in modern transmissions. While the issue affects a limited number of 2022 SUVs, rear wheel lock-up is a serious safety concern. Owners of affected Tahoe, Suburban, Yukon, and Escalade models should contact authorized dealers to schedule the necessary software update as soon as possible.
