“Various problems with electrical, heating and cooling, suspension, power steering, lighting, and purge valve systems. Spent 7k in last 3 years alone. Heating and cooling system was removed and reinstalled twice and still does not work right. Struts and steering system completely brakes down every 6 months. I am in the repair shop every 2-3 months! Average out of pocket (after extended warranty) $500... Outrageous (x4 or 5 per year!). Warranty kicks in another 4k per year. My records show 14 visits to mercedes repair shops since november 2004... Insane. This is my first and last mercedes! …”
NHTSA complaint #10213660, filed 2008-01, 39,000 miles“Faulty cup holder design which makes it easy for liquid contents to spill on the transmission/gear shifter and the computer chips below, resulting in engine stalling or failure of the electronic trransmission. This creates a dangerous situation because the car almost stops in the middle of traffic or slows down immediately.”
NHTSA complaint #10058343, filed 2004-02, 36,740 miles“Fumes/gasses coming from interior dash caused windshield to fog up in excessive heat. Dealership replaced windshield five times and replaced dashboard, but could not correct problem. Please provide any additional information/attachments.”
