Service bulletin L-TT-0257-19

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

TT: Some models are equipped with front and rear wheels of different offsets or width. Wheel offset, defined as the distance between the wheel?s centerline and the wheel-to-rotor mounting surface, affects the clearance between the back of the wheel and surrounding brake components (Figure 1). Installation of a wheel with an offset or width different than the correct specification, such as installing the rear wheel on the front, can cause damage to brake components due to interference between the wheel and adjacent parts. The wheel could contact the brake caliper thereby introducing stress into the caliper, brake rotor, and potentially other components. In some cases, this stress could contribute to cracking or separation of the brake rotor.
