What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint The vehicle pulls to the left or right. Cause In vehicles with Car Package Release "CPR" 2.1.0 or prior, the calibration value for the straight‑line stability of the electric power steering is not fully calibrated. Remedy Install Car Package Release 2.1.1 or later. Straight‑line normalization is then relearned during normal driving followed by a bus sleep. After the update, fault code P063544 may be active and stored in the electric power steering control unit, as the learned end stops are deleted during the update. This does not result in any functional limitations or warning messages; the end stops are learned during normal vehicle use. The fault code is cleared by automatic means after the teach‑in of the end stops is complete.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI46.00-P-081006 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the LI46.00-P-081006 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Mercedes-Benz warranty extension on file lists the ones Mercedes-Benz has filed.
Which vehicles does LI46.00-P-081006 cover?
The manufacturer filed it against 2 model years: 2027 Mercedes-Benz CLA-Class, 2026 Mercedes-Benz CLA-Class. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
