Chevrolet HHR Recalls

Ignition Lock Cylinder Concern

In order to help prevent rollaway type accidents, all late model vehicles are designed so that the transmission must be in park (or reverse for a manual transmission) before the ignition switch can be turned to the "off" position and the key removed. These vehicles are being recalled because the key can be removed when the ignition is not in the "off" position, increasing the risk of a rollaway type accident. Dealers will inspect the vehicle and replace the ignition lock cylinder as necessary. 2 new keys will also be supplied and programmed as required.

Unexpected Loss of Power Steering Assist

The vehicles being recalled are equipped with an electric power steering (EPS) assist system. The EPS can fail unexpectedly while driving. If this were to occur, steering ability would be maintained but much greater effort would be necessary to steer the vehicle, especially at slow speeds. One of four remedies will be applied depending on the model and year. Parts are not yet available so expect a second notification when they are. 

The AIrbags May Not Deploy as Expected

These vehicles are being recalled because the weight on the key ring and/or a jarring event while driving may cause the ignition switch to move out of the run position, turning off the engine. If the key is not in the run position, the air bags may not deploy in the event of a crash, increasing the risk of injury. Dealers will replace the ignition switch to correct this concern.

Currently it has 250,000 miles on it and starts and runs well. In the past 11 years I replaced the front rotors 2x, the battery once, the starter 2x and replaced the cheap plastic door handle once. Overall the car has been...
Bought a 2007 HHR to use as a tow car. It was sitting in our driveway, after taking grandkids to classes, and the interior just burst into flames. It had been sitting over an hour. The firemen and insurance company said it was electrical. WHY WOULD A CAR JUST BURST INTO FLAMES? Chevrolet is not interested in why this happened or the safety of its customers, or my family! I have contacted but t...
