Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

1999 Mercedes-Benz ML320 Owner Comments

problem #1

Jul 222000

ML320 3.2L V6

  • Automatic transmission
  • 54,200 miles


Fuel pump failure occurred five (5) times before MBUSA was able to fix the problem. The 1st 4 times they just replaced the fuel pump without fixing the problem, which was in the way the vehicle wiring was designed.

I'm lucky I bought an extended warranty from MB, but they tried to reneg on it at the last repair (at approx 93000 mi).

Lucky for me the dealer in Devon PA honored the waranty even though MB said it had lapsed (I bought and paid for 100k miles)

This problem caused me to get stuck on the road 2 times. The other 3 times I recognized the signs and drove it directly to the dealer. It died in the dealer's parking lot every time.

I traded this vehicle for a 2003 Toyota Highlander, which I still have - it now has 211k mi on it and runs very well.

I know that fuel pump failure is a recurring problem for 1999 ML320s - beware!!
