My 2006 ML350 had the Transmission, Steering and numerous issues. It was in the Penske Mercedes Service for 22 days for repair on the Steering issue and still has a steering problem. According to the Penske Service the following parts were replaced.
-Subframe Bushing Replaced
-Control Arm front axle replaced
-Tie Rod\Steering Joint replaced
-Steering Knuckle replaced

My 2006 ML350 has this engine\transmission problem; there is a harsh down shift\jerk intermittently. I brought it back to Penske Mercedes four times and flash the firm ware problem persist. Penske states that this is the nature of these new transmission technologies. “It is normal to have this problem”; what kind of answer it that? This problem started at 800 miles, the vehicle currently have only approximately 14,500 miles as of today 7/20/07, still very new.

Plus I have had my ML350 in for service with 12 different problems and have been in the dealer repair shop for 44 days all together. Three of the 12 problems are engine related. The most serious engine\transmission problem was it will not shift out the DRIVE Gear. The vehicle was stuck in Drive Gear, will not Park or Reverse with message warning “Drive to work shop immediately without changing gear”!!!

I have contacted MBUSA 3 times to request to have this vehicle replace or buy back due to the excess repair and down time. I was told by Penske Mercedes\MBUSA that this ML350 was not qualifying for their buy back or replacement program.

MBUSA do not even have an arbitration program for protection under the Lemon Law. Accordingly this vehicle have been in for service for 44 days combine and have had 12 different issues, with 1 issue repeated 4 times, less than 18 months period. According to the Lemon Law this ML350 is entitle to buy back or replacement.

What am I to do? Help…can anyone out there please give me some pointer.

Thanks!

 

yes hush down shift requires software programming on the new 722.9 gear box which is a 7 speed gear box,after programme you ll will not have any trouble did 1 2 weeks ago,it was done in about 4 hours,i just cant beleave they sayin to you its normal,if only you where at my delaer ship you would be the happiest customer ,thats in uk.

MBUSA finally refund/buy back my ML350 lemon the beginning of this month. After numerous calls and two letters to MBUSA, they finally declare the vehicle has a transmission problem. It was a tough and time consuming fight with the dealership service manager and MBUSA. They refunded my down payment, monthly payment and payoff the amount owned to the bank, but they did deduct the mileage I have used on it. What a headache owning this vehicle have been.
