Bmw recalls X3 — Replace the engine starter motor

Recall Details

Defect: The Safety Recall relates to the engine starter motor. The fault relates to the RSW22 starter RWT (reinforced water tightness). It was found that with RWT starters an increased abrasion of the magnetic contact can cause the growth of deposits at the lowest point of the relay interior. This in turn may increase the relay contact resistance resulting in false starts or even causing short circuits and possibly a thermal reaction. In case of a short circuit the possibility of a thermal event cannot be excluded. This may happen while attempting to start the vehicle or while driving due to vibrations causing a short circuit due to moving deposits.

Remedy: On the affected vehicles the starter motor will be replaced with a variant by another supplier with a different design. Until the repair has been completed it is recommended to not leave the vehicle running unattended after starting the engine.

Vehicles affected: 1502

DVSA Recall Number: R/2026/054
