General Motors announced four additional recalls Friday morning.
The largest recall is for current generation Chevy Camaros, model years 2010-2014, because of an ignition switch problem. The driver's knee can bump the key FOB and cause the key to move out of the "run" position, which would cause the car to lose power.
WDIV reports the problem was discovered during an internal testing following the ignition switch recall earlier this year.
The recall affects 511,528 Camaro muscle cars from 2010-2014 in the United States.
GM said it is aware of three crashes that caused four "minor injuries" that were likely related to the issue.
"The Camaro ignition system meets all GM engineering specifications and is unrelated to the ignition system used in Chevrolet Cobalts and other small cars included in the ignition switch recall," GM said in a statement.
In addition to the Camaro recall, GM has recalled the following models:
-28,789 Saab 9-3 convertibles from the 2004-2011 model years for a driver's side seatbelt issue
-21,567 Chevrolet Sonic 2012 model year compacts for a problem with the transmission turbine shaft
-14,765 2014 Buick LaCrosse sedans for a wiring splice in the driver's door that may corrode and break.
