Chrysler Group is expanding an earlier recall of Jeep Liberty SUVs, adding 137,000 more vehicles.
The total number of vehicles being recalled is now 346,900.
The recall originally covered 2004 and 2005 model year SUVs but Liberty models from 2006 and 2007 have now been added to the list. The recall covers vehicles in northern states where road salts, used to melt snow and ice, could cause part of the SUV's rear suspension to corrode and break.
The lower control arm helps keep the rear suspension from moving forward and back and a break could cause a loss of steering control.
The National Highway Traffic Safety Administration had opened an investigation into the Jeep Liberty problem in April after receiving 9 reports of lower control arm fractures.
There have been no reports accidents or injuries resulting from this problem, Chrysler spokesman Eric Mayne said.
Owners who have already had the control arms replaced will be reimbursed for the expense
