(Detroit -- Jerome Vaughn, WDET) General Motors is expanding a recall of sport utility vehicles and pickup trucks because of a faulty part could cause the rear axle to lock up.
The recall includes a dozen different models from 2011, including the Cadillac Escalade SUV as well as the Chevrolet Avalanche and GMC Canyon pickup trucks.
The National Highway Traffic Safety Administration says pins in the rear axle may not have been heat treated…making them more susceptible to fracture. Broken pins could allow the rear axle to lock, increasing the possibility of a crash.
GM had originally recalled 1,200 vehicles last month, but expanded the action to more than 26,000 after finding more trucks with the faulty parts.
The automaker is advising owners not to drive the vehicles until the rear axle pins have been replaced by dealers.
