Example complaints

“Sunroof exploded as I was driving down the freeway. Roadway was smooth and there were no cars in front of me so I'm certain it wasn't a rock or other object that broke it.”

NHTSA complaint #11184270, filed 2019-03, 67,000 miles

“Oil leaking and wicking into camshaft position sensors, camshaft magnets, O2 sensors, engine wiring harness and ultimately, the ECU is destroying all electronic components connected to the engine causing misfiring and seizing. The issue is quite prevalent via internet research as potentially thousands of owners all experience the same issue. Our local Mercedes Benz dealer indicated this issue just popped up immediately outside the warranty period (1 yr) for our used purchase, and would require a replacement of the camshaft, sensors, magnets, and wiring harness to the tune of $14,000. …”
