Official summary
Some vehicles may exhibit a rattle noise from the front suspension when driving over bumps or on a road with a wavy surface. The noise may be caused by the mounting rubber (1) because of insufficient clearance between the rubber and the metal bracket of the mounting rubber during the assembly process. To correct this issue, the mounting rubber has been modified to ensure the proper clearance.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
