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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11038190-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11038190-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11038190","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["P0635"],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"CLA 220","year_from":2027,"year_to":2027,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"CLA 250+ (EV)","year_from":2026,"year_to":2027,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"CLA 350 4MATIC (EV)","year_from":2026,"year_to":2027,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
