Official summary
Some vehicles may exhibit: Vehicle body vibration when moving from a stop while using the Electric Parking Brake (EPB) automatic release function. Uneven rear brake pad wear. These concerns may be caused because the automatic EPB caliper release timing is too late for the movement of the vehicle. NOTE: Frequent usage of the EPB automatic release function may promote uneven rear brake pad wear. To eliminate these concerns, the EPB control module logic has been modified.
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.
