In September, the National Highway Traffic Safety Administration began a probe of 2002 and 2003 Jeep Liberty models. Owners were reporting that airbags were deploying when there hadn't been an accident. At the time, there were 39 complaints filed: seven to NHTSA and 32 field reports from Chrysler. Ten of those complaints resulted in injuries.
A report by The Detroit News says the probe has been upgraded – there have now been 87 complaints, with 50 of them resulting in injury. Chrysler hasn't been able to nail down a single cause of, or even a single protocol for the problem; the airbags have deployed on startup and when the car is running – sometimes it's just the driver's side unit and sometimes it's both driver and passenger bags.
There are 386,873 Liberty vehicles included in the probe from those two model years. Chrysler says it is cooperating fully with the investigation and trying to find the source of the issue, with one suggestion being "a transient voltage spike" in a circuit.
