04-25-19R2019-09-05. Service bulletin. STEERING. "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.
07-137-182018-08-20. Service bulletin. STEERING. Models with Automatic Headlight Beam Leveler System only. This Service Information bulletin announces a revision to the diagnostic procedure used when diagnosing either DTC B2910 or 2911 ?Steering Responsive Headlight Communication? LH or RH.

This bulletin announces availability of ECM reprogramming files to optimize the ECM with improved diagnostic logic for DTC P0852 (Park/Neutral Switch Input Circuit High) detection. If the shifter is moved too fast, the gear change may not be properly detected by the ECM causing the P0852 to set.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
