Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving vehicle power can be lost & vehicle can be stuck in 1st gear or no gear at all causing blockage to traffic and possibly causing an accident. Once you turn car off it appears the car resets itself as if nothing ever happen. When reported to dealership it was stated no codes pop up so I must be hitting the shift. Not knowing any better & not being a mechanic, who am I to continue to question the mercedes dealership? No code no action. (1st reported with 8446 mileage never showed a code). At 63,000 miles the engine light finally comes on indicating a problem. …”
