Example complaints
Electrical system: “Mercedes-benz engine wiring harness defect concerning the chronic engine compartment wiring harness failure suffered by (at least) 1992 through 1995 mercedes benz automobiles. I am outraged at Mercedes-Benz' refusal to take responsibility for this design defect. I do not understand why NHTSA has not investigated this dangerous fault, especially with the huge number of complaints. One starts to wonder if NHTSA has been paid to look the other way.”
NHTSA complaint #10300109, filed 2010-01, 130,000 milesSuspension: “Mercedes dealer repair shop reported to me that the wiring harness is made of biodegradable material and had to be replaced. The faulty harness caused several problems with engine, including acceleration. I had the part replaced in 2000 and do not have the original. Both catalytic converters went bad at 100,000 miles for no reason. Makes car run rough, especially on acceleration. Mercedes mechanic states it is a fire hazard, and cost to replace exceeds $2200. Should have been included in recall for later models. Suspension is bad in the rear even after parts have been replaced.”
