Model Years Affected: 2008, 2009, 2010, 2011

Drive Train Affected: Automatic Transmission

Average Mileage: 53,714 mi (14,000 mi - 88,000 mi)


A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

    Knocking noise notices when turning right primarily. I sometimes hear the same noise when turning left. I thought it might be associated with rear struts or shocks.
