A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

A woman ran a red light and crashed into the front passenger side of my 2004 mercedes benz ml 350. After the impact there was smoke coming from under the hood. A driver coming from the opposite direction yelled out that my car was on fire. When I got out of the car, I saw a big puddle under the car and it ignited. Within a few minutes the car was completely engulfed in flames.

Reported at 55,000 miles, January 2012 CrashInjury

The driver seat heater over-heated and caused a minor burn when I took the car to the dealer. The dealer agreed to pay for half the cost of replacement but would not give the defective part back to me even when I specifically asked for it. While searching for more information, I came across other incidents with this car with the exact same problem.

Reported at 102,000 miles, February 2009 Injury

Crack in fron bumper with no other discernible damage. All lights and casings in tact with no markings to indicate crash.

Reported at 11,000 miles, September 2004

SRS and airbag lights remain on. I won't bother with the dealer because I have seen numerous complaints on various blogs of people with the same issue who have been told that this is a $750 sensor that needs to be replaced. Mercedes should seek recourse with their suppliers and stand behind their "world-class german engineering" and make their customers whole.
