Chevrolet Gmc Cadillac Recall: GM pulls more than 43,000 vehicles over transmission valve fault
General Motors has opened a chevrolet gmc cadillac recall after a safety notice identified a transmission control valve fault that may cause rear wheels to lock, increasing crash risk. The recall covers 43, 732 vehicles and owners are expected to receive notification letters on March 30 (ET); affected vehicles will receive a free transmission control module software update.
Chevrolet Gmc Cadillac Recall: scope and models
The U. S. notice lists a total of 43, 732 Chevrolet, GMC and Cadillac vehicles included in the action. The campaign targets full‑size SUVs from recent model years—specifically the Chevrolet Tahoe and Suburban, Cadillac Escalade and GMC Yukon—and is tied to a transmission control valve on the ten‑speed transmission used in those vehicles.
In Canada, a parallel recall record notes about 2, 071 similarly equipped full‑size SUVs affected in that market. Separately, an earlier Canadian recall in October 2024 covered more than 50, 000 trucks, including Chevrolet Silverado and GMC Sierra pickups; that earlier campaign cited a related transmission concern and at the time said only diesel‑equipped vehicles were affected.
Risk and technical fix
The notice states the transmission control valve may wear and fail unexpectedly; that failure can lock the rear wheels while driving, which raises the risk of a crash. The remedy issued for the current campaign is a transmission control module software update to be installed at no charge on impacted vehicles.
Dealer instructions tied to the broader campaign call for technicians to inspect vehicles to determine whether an incorrect software update was installed after the original recall action. If an incorrect update is present, dealers are to perform a new software update to correct the condition.
Owner next steps and timeline
Owners included in the chevrolet gmc cadillac recall should expect notification letters on March 30 (ET) that explain the remedy and dealer procedures. Vehicle owners can check the federal recall database using their vehicle identification number (VIN) to confirm whether a specific car is covered.
Given the inspection and reflash steps described in the notices, owners whose vehicles previously received the earlier software update may still require a dealer inspection to verify that the correct update was applied. If an incorrect update was installed, dealers will perform the new update at no charge.
For owners in Canada, the separate recall record lists the approximate number of affected SUVs in that market and may follow a different timetable for owner notifications and repairs.
Forward look: the immediate next milestone is the owner notification mailing on March 30 (ET) and the subsequent dealer inspections and software updates. If dealer inspections find incorrect prior updates, a second, corrective software update will be applied; otherwise, routine dealer service should address the issue once notified.
