GM recalls SUVs over transmission defect causing sudden rear‑wheel lock

GM issues recall over sudden rear‑wheel lock risk in SUVs

Transmission failure prompts safety recall

General Motors Co. is recalling multiple SUVs after identifying a transmission defect that can cause the rear wheels to lock up, creating a sudden loss of rear‑wheel rotation and sharply reducing vehicle stability. The company says the condition is a failure in the transmission system rather than a driver‑controlled function, meaning it can occur during normal driving without prior warning and increase the risk of a crash.

GM is notifying owners that affected vehicles must be inspected and repaired by authorized dealers at no charge under the recall program. The initial announcement names multiple SUV models across the automaker’s portfolio but does not list specific model names or a vehicle count, so owners are urged to confirm inclusion by checking GM’s recall website or contacting the company directly with their vehicle identification number (VIN).

The company frames the action as an immediate safety priority and outlines remedies that include parts replacement or repair procedures performed by dealers to restore normal drivetrain operation. GM asks owners to document any transmission symptoms when arranging service so technicians can diagnose and address the defect efficiently, and it warns drivers to avoid high‑speed operation if they suspect transmission irregularities pending repair.

Service logistics and dealer coordination

GM says it is coordinating with its dealer network to schedule inspections and repairs as parts and appointment availability permit, acknowledging that logistics may affect the speed at which affected vehicles are remedied. Dealers are handling diagnostic checks and implementing corrective parts or software updates where required, and GM is working to prioritize vehicles based on risk and reported symptoms.

Regulatory context and owner guidance

The recall highlights broader safety concerns around drivetrain malfunctions that can precipitate spins and loss of steering control. GM is expected to work with regulators as the investigation into root causes continues, and it encourages owners to report transmission issues promptly, retain service records, and verify recall status with their VIN to ensure timely corrective action.
