Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was driving down a paved road, went to make a left hand turn and my esp came on, vehicle shut off and almost ran me into another vehicle, which then caused me to run into the ditch. Now I'm finding out that there is a recall on the sbc unit, which is what's wrong with my car, but the recall is not showing up for my VIN number. I am very, very disappointed/frustrated by mercedes. This is a very expensive part to replace. …”
