Five problems related to engine and engine cooling have been reported for the 1999 Mercedes Benz ML320. The most recently reported issues are listed below.
Driving home from work the car's idle went to zero. This happened half-way home. Its a 30+ mile drive from work to home. Essentially the car just quit operating while merging on the interstate. Power steering was lost and this left my 8 month pregnant wife stranded in the middle of the merging lane to the interstate without the capability to restart the car. Successive tries to start the car failed. Only after 5 minutes the car was able to start and be pulled over to a safe place. Tried a 2nd time to drive it home and it left me stranded again without it being able to restart. Had to be towed on a flatbed tow truck home the remainder of the drive home.
Fuel gauge does not read correctly/run out of fuel/engine quits loss of control, power brakes and steering may lead to crash/defect.
The harmonic balancer on my 1999 mercedes Ml320 engine type m112 failed and resulted in $4,000 to repair. The part failed with no advanced warning. Even the mercedes dealership who performed the power steering recall two weeks prior to the failure did not spot any problem and they knew to be looking. I was lucky the failure occurred in my driveway backing out of the garage in stead of on the freeway with an immediate loss of power steering or destruction of the engine.
I had to replace the harmonic balancer, and the main drive shaft bearing on a 1999 ml mercedes with the v-6 motor VIN 4jgab54exxa055878.
While driving the vehicle at 55mph on average, engine misfired. Consumer stated has to pull of the road, and restarted the engine, but as soon as reaching high speed, will be the same problem. Dealer has not yet notified. Vehicle is without warranty.
