Service bulletin 04-25-19R

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

"The primary focus of this bulletin is to provide a procedure to follow when diagnosing a customer concern of Torque Steer, defined as a pulling condition to either the left or right when under full acceleration which requires a somewhat greater than standard correction of steering wheel input from the driver to counteract. As part of this diagnosis, it will be necessary to first eliminate two other conditions a customer may misinterpret as torque steer. These are: Steering Pull and Steering Off-Center. This will prevent incorrect or over-repair, both of which can negatively impact customer satisfaction. This bulletin applies only in cases where the original factory equipment wheels, tires, and all suspension components are currently installed and, the outlined condition is confirmed to be present.
