Known issues on the 2003 ML55 AMG. NHTSA's record shows three recalls filed against the 2003 M-Class line. Two concerned certain vehicles with a clamp on the power steering fluid cooler hose that could fail to hold, so fluid leaked away and steering assist weakened; a new clamp was the fix. The third covered certain vehicles in which a tap on the brake pedal might leave cruise control engaged. A single owner complaint about the service brakes names this model, and nine complaints were filed against the 2003 M-Class line, four of them electrical. Power steering, cruise control and brake system procedures appear in the manual.
