Jeep no start

Diagnose and fix Jeep no start

Chrysler has issued a service bulletin #08-025-12 to address a Jeep no start or hard start condition on the vehicles listed below. The symptoms mimic a dead battery and result in a no-start, hard start, long crank condition after the vehicle sits for a few hours.

Cause of Jeep no start

Chrysler has determined that the radio software is at fault and is draining the battery, causing the starting problems. The radio electronics are supposed to go into “sleep mode” to reduce battery drain. In some cases, on the vehicles listed below, the radio “wakes up” and drains the battery at the rate of 2-amps continuously. The fix is a radio software update.
