Known issues on the 2008 Wrangler. Eight recalls are on federal record for this model year: a floor liner that can shift forward and impede the accelerator, a passenger-side frontal air bag inflator, a driver-side air bag circuit failure that can prevent the driver's frontal air bag from deploying, a tow bar that can fail and let a towed vehicle separate, two broken air bag clockspring circuits that can keep an air bag from deploying, automatic transmission fluid that can boil over onto a hot engine or exhaust component and cause a fire, and a brake fluid leak that can cause a partial loss of braking at the affected wheel. Owners have filed 1,252 complaints and Jeep has issued 49 technical service bulletins for the year.

From a routine service interval to a hard-to-trace wiring fault, this manual keeps you on the correct procedure and specification for your specific 2008 Wrangler.
