Transmission issues

According to the NHTSA, the current recall only impacts vehicles equipped with diesel engines. The transmission control valve in some affected cars is susceptible to wear over period, which can factor fluid to leak and navigator to a drop in pressure within the valve. This can factor harsh shifting or the rear wheels to lock up. Drivers may notice the harsh shifting before any wheel problems occur.

The recall notice cited customer reports dating back to January 2020, which prompted an investigation into the issue beginning in July 2024. GM found 1,888 field reports of wheel lockups potentially related to the issue. GM also found 11 incidences potentially associated with the state, several of which caused vehicles to veer off the road, minor property damage, and, in three cases, minor injuries.

How to get your car fixed

Dealers will install recent transmission control module software free of expense. This module will monitor valve act and detect excess wear approximately 10,000 miles before a wheel lock-up state could occur. If detected, the transmission will shift gears to prevent lock up and a service engine light and reduced propulsion communication will display.

GM will also provide a special program to cover the repair of transmissions that the software identifies as having a defective control valve.

Owners of affected cars will be notified via mail. They may also contact GM customer service at 1-888-988-7267, Cadillac customer service at 1-800-458-8006, GMC customer service at GMC 1-800-462-8782 or Chevrolet customer service at 1-800-222-1020 with recall number N242454440.
