Official summary
The brake fluid used during the production of the potentially affected vehicles may have contained excess moisture. Excess moisture in brake fluid may cause a gelatinous material to form in the brake system. This material may accumulate and temporarily clog stability control-related valve filter(s) in the Vehicle Dynamics Control (VDC) system. In this situation, VDC performance may not fully comply with the FMVSS No.126 requirement. However, the brakes will continue to operate normally.
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.
