NHTSA Probes Chrysler Ignition Switch Problems

The U.S. has opened two investigations into ignition switches in several Chrysler Group LLC models that can inadvertently cut power to the engine and prevent airbags from deploying in a subsequent crash.

One probe involves 2006-2007 model Jeep Commander SUVs and 2005-2006 model Jeeps Grand Cherokee SUVs. The National Highway Traffic Safety Administration reports nearly three dozen complaints that the switch can kill power to the engine if the driver's knee or leg brushes the ignition key fob or keychain.

A second investigation revisits a previous ignition switch recall for 2010 model Chrysler Town & Country minivans and Dodge Journey crossovers and Grand Caravan minivans.

Chrysler recalled those vehicles in 2011 to repair switches that could spring back to a position between "run" and "accessory" after being twisted to the "start" position. Under those conditions, the switch could then be jolted by a bump in the road into the accessory position, thus turning off the engine while the vehicle is in motion.

NHTSA says it has received complaints that Chrysler's previous repair failed to remedy the flaw. The agency also is looking into complaints about the same problem in 2008-2009 models.
