One problem related to turn signal has been reported for the 2010 Chevrolet HHR. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2010 Chevrolet HHR based on all problems reported for the 2010 HHR.
1) the turn signals have failed to cancel after a turn on an intermittent basis since the car was new. 2) recently, the turn signal will not hold in the on position on a left turn and has to be manually held down to actuate the signal for the entire turn. 3) at the same time, the right signal will no longer automatically cancel and has to be manually turned off after a turn. These are issues because you either have the turn signal not on during a cross traffic turn when you thought it was engaged, or you have it on when you thought it had automatically shut off.
