Component/System: The intake camshaft positioner/adjuster on cylinder bank 2 of the M276 V6 engine has failed, along with associated timing components. The vehicle (2018 Mercedes-Benz E400, VIN [XXX]) remains unrepaired and is available for inspection upon request. Safety Risk: The engine produces a loud metallic rattle on cold starts, indicating loss of proper camshaft timing control. If unaddressed, camshaft timing deviation can progress to timing chain failure, which on interference engines can cause valve-to-piston contact and sudden, severe engine damage or loss of power while driving, posing a risk to vehicle control. Confirmed by Dealer: Yes. Mercedes-Benz of Catonsville (RO# [XXX]) diagnosed the issue and confirmed stored fault code P002177, indicating the intake camshaft position on cylinder bank 2 deviates from its specified value.

Despite multiple attempts, including a promised callback that was never received and nearly an hour on hold with no resolution, Mercedes-Benz USA has not adequately responded or

The contact owns a 2018 Mercedes-Benz E400 4MATIC.

The manufacturer was contacted and informed the contact that the remedy was not yet available. The failure mileage was approximately 84,000.
