On several occasions, while moving in traffic, the vehicle will jump from drive to neutral; the engine is disengaged and revs freely. The vehicle will not engage back into drive until the ignition is completely turned off, which locks the steering wheel, so the driver must exit the traffic lanes with no power before the vehicle can be restarted. This has almost cause a collision as the driver has no control of the car but must exit high speed traffic lanes, or come to a complete stop in the middle of a freeway.

Conductor plate transmission issue

Filed Nov 7, 2016 · Engine, Steering · 107,000 miles · AZ

Serpentine belt system. While driving on road at the highway speed, one of the idler pulleys locked up due to the failed bearing, leading to damaging/braking serpentine belt. That LED to loss of steering (loss of power steering) and overheating the engine. Created a very danger situation and left my family stranded many miles away from home. Very costly towing service and repair.

Safety issues being observed on ml 350 2007 observations (my wife & I have both experienced): automatic transmission , experiencing limp mode creating a safety issues which cannot be foreseen, can happen any time the problem occurs when you least expect it and unpredictable, it will be driving fine and then all of a sudden it will start losing power in traffic & drag down. Also, the vehicle will start shifting by itself from one gear to another & the speed of the cars starts to crawl, like "limp mode" the idle speed starts to rev up, car is not increasing the speed as one would expect once normally when pressing on the gas pedal. One has to pull over if they can or stuck in the street one is driving which I experienced and tried to pull over & had issues. I basically had to turn the engine off in the middle of the road while driving and hoped the car would start back again, I had to repeat this several times as I experienced the drag down and gears going down. Very scary incidents with children & wife in the car when I was coming back from an occasion (I.e. Driving back home). Told by dealer on 10/11/16: code 0717 & 0718 & not covered under warranty 4 years/50k potentially related issue: code 064 incident had occured several times now in the last few weeks

We are having some serious issues with our mercedes benz ml350, 2007. The safety hazard concerns us deeply. Based upon our research, we have discovered that this is a common problem. Others are facing the same issues with this vehicle. This problem occurs when you least expect it. It will be driving fine and then all of a sudden, it will lose all power in the traffic where you are totally helpless and unable to pull over. This is very dangerous because the vehicle slows down unexpectedly which can cause a major accident. Example: when you are crossing a highway; you think the vehicle will drive normal. But then all of a sudden it drags. Therefore, you will have to crawl. Each time we have to restart the vehicle. It appears that the vehicle resets itself when the engine is turned off. Then the vehicle proceeds as normal. Another example: it won't shift from second gear to third, and you can only crawl 10-40 MPH. It refuses to shift any more. Other drivers around us on the road become extremely impatient and start screaming and using violent gestures. Another time, I was coming off a highway merging to the access road. The vehicle slowed down. I pressed on the gas, the engine revved up but the car slowed down to about 35mph and a 18 wheeler behind us almost hit us by swerving to avoid a major accident. I had to crawl on the access road with fast moving traffic. There are other reports with the 2007 mercedes benz ml350 power train (transmission) to have these issues. The reports I have read indicated that the mercedes benz corporation is not willing to own up to the fact that this vehicle is very dangerous and can cause serious implications. I plead for your help to please look into this matter so that others with the same problem with this car can be spared. We are appealing for your help.

Started my 2007 mercedes benz ml 350 with only 46,000 miles driven and pulled onto major street in jacksonville, fl. Car would not shift from first gear - could not get it to go over 20 MPH. Cars whizzing by me. Surprised I didn't get hit. Took the car to mercedes dealer. First problem on estimate is: "replace transmission electrical plate (faulty transmission electrical plate)". Mb admits 722.9 transmission is faulty. However, they will only accept responsibility to repair vehicles in warranty. My vehicle is out of warranty by # of years, not mileage. A car should not need transmission work at 46,000 miles. Went online to research and this is a problem of many cars with 722.9 transmission. My cost to fix will be $1100 for the transmission electrical plate. In addition, received a call after 3 days in shop that they will also need to replace the torque converter. The dealer is coping the cost to replace the torque converter. Car is still in the shop. I am reporting because this is a safety issue. If the gears will not change when you pull into traffic, how long will it be before someone is seriously injured. Another complaint listed online was that the car jumps out of gear on expressway. I think there should be a recall on all cars with this transmission. The dealer is working with me and has provided a loaner car. However, I think mercedes benz should be repairing this problem on all cars that have the problem, whether in warranty or out, at their cost.

Per an e-mail sent to daimler ag-mercedes, I have a 2007 ml350 with only 66,000 miles which is not safe to drive as the car is not shifting from 1st to 2nd gear. The facts are: there have been many instances, reports, & complaints to mercedes where this has happened. It is not safe & the mercedes car should be recalled for repair.it should not be occurring at all especially with only 66,000 miles. Car has been taken to the sarasota, fl mercedes dealer. Cost is $1,700 which should be covered & corrected by mercedes. We currently have 2 mercedes & have had mercedes for 20 years this is an unsafe situation; it has occurred with other cars; and mercedes has received many complaints. This is not a repair issue; it is a safety issue. The speed sensor that mercedes is repairing is a hazardous situation due to the fact that the car stops shifting to any gear when leaving a stop sign or traffic light and will not accelerate. This is particularly dangerous in high traffic areas. We have had mercedes for 20 years & are aware that repairs are costly, but this is a safety issue. This is a problem that should not be occurring and it should be the responsibility of mercedes to correct it. It would be prudent of mercedes to issue a warning of the possibility of transmission error. Thank you for your assistance and cooperation.
