Example complaints
One per model year, chosen for length and detail. Personal details are removed. They are consumer reports, not findings.
2012: “Takata recall - while driving along a county street my vehicle completely stalled. I put in park and it started and went approximately a 1/2 of a mile and stalled again. It did this twice more before I got home where I shut it off and called a tow company to take it to the shop. My service advisor call and told me that the wiring hones to the engine burned up.”
NHTSA complaint #11082046, filed 2018-03, 65,000 miles2010: “Takata recall we have been notified in february of 2016 and it is now november of 2016 and still no parts. We can't sell the car because I don't want to pass the problem onto another person and mercedes won't give us a loaner so we have a potential risk. Telling us that it is a minimal risk doesn't help. This is beyond irresponsible! Can you please advise”
NHTSA complaint #10925705, filed 2016-11, 95,000 miles2008: “Car occasionally difficult to steer after driving for distance in mountains. Fluid levels appear to be ok but passerby's tell me they can hear steering noise that I do not hear inside when driving. I saw that there is recall for this vehicle and steering rack pin- wondering if my vehicle is part of recall to be repaired by mercedes.”
