Service bulletin 3678

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

G-2089392016-09-08. Service bulletin. 14119 - SPECIAL COVERAGE (MESSAGE ONLY - CUSTOMER LETTER MAILING NOTIFICATION). SOME 2006-2009 MODEL YEAR CHEVROLET HHR (NON-TURBO) AND 2003 MODEL YEAR SATURN ION VEHICLES EQUIPPED WITH ELECTRIC POWER STEERING MAY EXPERIENCE A SUDDEN LOSS OF POWER STEERING ASSIST THAT COULD OCCUR AT ANY TIME WHILE DRIVING. IF THE POWER STEERING ASSIST IS LOST, A MESSAGE IS DISPLAYED ON THE DRIVER INFORMATION CENTER AND A CHIME SOUNDS TO INFORM THE DRIVER. STEERING CONTROL CAN BE MAINTAINED, AS THE VEHICLE WILL REVERT TO A MANUAL STEERING MODE, BUT WOULD REQUIRE GREATER DRIVER EFFORT AT LOW VEHICLE SPEEDS, WHICH COULD RESULT IN AN INCREASED RISK OF A CRASH. DEALERS ARE TO REPLACE THE POWER STEERING MOTOR.
