General Motors have announced a recall of more than 313,000 Saturn, Pontiac and Cadillac vehicles around the globe to fix a rear-axle seal that may leak and cause the cars to lose control and crash.

“A fluid leak in the rear-axle pinion seal may cause the vehicles’ rear differential to lock up, possibly causing a loss of control” GM said in a letter to NHTSA.

The company said it had received a “higher than normal” number of warranty claims for the faulty seal. Two crashes were reported, one involved an injury caused by moving around inside the car as the vehicle lost control.

The recall effects the 2007 Saturn Sky and 2006-2007 Pontiac Solstice both of which are based on GM’s Kappa rear-wheel-drive compact performance platform.
