Affects the following:

2018 MERCEDES BENZ C 300 4MATIC Complaints
Sunroof causing dangerous pinch conditions. Roof tracks break and cause pinch areas with partial opening of roof;
2018 MERCEDES-BENZ E 400 4MATIC Complaints
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. The dealer's own notes state camshaft adjusters "are prone to failure and commonly damage camshafts when they fail." Manufacturer Notified: I contacted Mercedes-Benz USA directly (Case #[XXX]) to request they address this repair, citing that this camshaft/timing failure is a known, recurring issue on M276-equipped vehicles, supported by Mercedes' own technical service bulletins (TSB LI05.10-P-056435 and TSB LI05.20-P-059966) describing this exact failure pattern. 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 taken action. Warning Signs: The check engine light illuminated in early August 2026, prompting a dealer visit. The cold-start rattle was identified by the dealer during diagnosis the following day. No prior symptoms were noticed beforehand. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6);
