Thousands of Chryslers to be recalled in Australia 'I bought a Jeep' advertisement campaign shows shocked people questioning the purchase of a Jeep. Credit: Jeep Australia THOUSANDS of Chrysler cars in Australia are being recalled as part of a worldwide problem with automatic head restraints. Fiat Chrysler Australia says 3725 Jeep Cherokee cars and 520 Dodge Nitro vehicles built between 2011 and 2013 are affected in Australia. Chrysler announced on Wednesday it was recalling about 490,000 cars and sports utility vehicles to fix the glitch. The US manufacturer says potentially fatal microcontrollers have been installed in certain vehicles that may prevent head restraints from automatically moving forward during some kinds of rear-impact collisions. Fiat Chrysler Australia will contact all Australian owners of affected cars and ask them to go to their local Chrysler Jeep and Dodge dealer, a company spokeswoman says. "We will then replace the component or upgrade the system software at no cost to customers," she said. The spokeswoman said they were not aware of any injuries or accidents associated with the problem. If customers have any concerns before they are contacted by the company, they can go straight to their local dealer, she said.
