2007 Chevrolet HHR ProblemsCheck Engine Light Due to Gas Cap Issue
A Loose or worn gas cap may cause Check Engine Light to illuminate.
THIS CAR HAS A RELAY FOR THE STARTER .. IF YOU DON'T KNOW WHICH ONE IT IS... PUSH ON ALL THE RELAYS AND FUSES ( UNDER THE HOOD ,DRIVERS SIDE, IN A BLACK BOX.. REMOVE COVER CAREFULLY ) AND YOU MIGHT FIND ONE THAT IS A BIT LOOSE .. THIS HAPPENED TO MY BRAND NEW HHR.. I HAD TO INFORM MY DEALER WHO NEVER HEARD OF THIS PROBLEM...
DO THIS BEFORE YOU REPLACE THE STARTER OR BATTERY...
GM recommends replacing the engine coolant at 100,000 miles; however, our technicians tell us that the coolant may become contaminated and require a complete cooling system flush every 60,000 to 70,000 miles.

2007 Chevrolet HHR RecallsIgnition 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.
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.
The door on the dash storage bin may not stay closed in the event of a crash, increasing the risk of personal injury. Dealers will install a redesigned latch to correct this issue. This recall will begin on December 23, 2008. The General Motors recall number is 08157.
