RepairPal Certified shops can diagnose and repair your 2009 Dodge Avenger. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Check the battery voltage. It should be at least 11 volts. You can also try jump starting the car. If that works drive it to a local auto parts store and have them load test the battery. It may be time for a new one.
