Replace engine, transmission, 3 suspensions is 3 years-twice on the right side Mercedes and intercar claimed that right rear air spring had a leak left rear shock leaking and claimed normal wear and tear at 71725 miles-so was the pages and pages of the link below at 71000 miles, power door locks stopped working, power drivers mirror stopped working, safety lock for back windows stop working, burns 2 quarts of oil a month, sunroof leaks, and doesn't always close all the way, ABS speed sensors defective, rear main radial seal in transmission defective, replace defective engine thermostat, replaced the batteries due to corrosion (under the seat), faulty signals for tail lights and parking tail lamps (electrical), air conditioning ambient sensor defective, replace defective radio antenna. This car has major design flaws, and has been discontinued by mb. My 2007 R350 has hit every defect listed below with the exception of parking brake, and steering column. Mercedes-Benz always claims it is normal wear and tear. I know of no car let alone a Mercedes with this many defects, I want them to buy this piece of junk back, they offered me 2000 towards a new Mercedes, I have been driving Mercedes since 1995 and never had problems like this. You would think as many of their cars I owned that they would have stepped up to save not just their reputation but O save a client. Suspension complaints: All at similar mileage, mb response was normal wear and tear. www.aboutautomobile.com/complaint/2007/Mercedes-Benz/R350/suspension.
