What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Wire harness shorted out due to naked wires with no insulation causing the harness to catch fire burning harness and frying the alternator. The cause was said to be wire harness deteriorated. Improper insulation on the harness.
The engine control/fuel injection wiring harness of my 1995 mercedes-benz s420 (61,000 miles), has cracked insulation throughout and is beginning to short-circuit with the risk of causing dangerous engine malfunction--and even fire--inside my engine compartment.
The contact stated that the vehicle would independently engage in limp mode causing the vehicle to become resistant to acceleration over 25 mph. The contact took the vehicle to the dealer and was told that the failure was coming from the wiring harness that was connected from the computer to the engine.
Engine started to run poorly while underway and then quit entirely. Traced to shorts in engine wiring caused by a disintegration of insulation in engine compartment. There seemed to be a burning at the site of the failure by the discoloring of the copper stands.
On end of september the engine light comes on and I changed the air mass flow sensor than a month later the a/c sometimes work and other times not I changed the vacuum hoses that goes to ac solenoid plus the egr hose, and one wire that goes to the a/c relay.
I had two unexplained blowouts on the highway, and a year later a "bubble" on the sidewall of another tire. My experience as an ex-aircraft mechanic (16 years), allowed me to know these tires are unsafe and I replaced them all.
Engine continued to roar for 2-3 minutes then stalled, black smoke from the exhaust. 6 weeks prior to this dealer did $ 7200.00 of engine work. Dealer determined the acceleration was caused by a jammed fuel injector pump.
Rear seat belt locks up. Imported repair shop ordered several seat belts, all were having the same problem. Consumer contacted manufacturer & they didn't know of the problem.
