problem #4

Oct 312016


  • 107,000 miles


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

1) car is having recurring issue with seat burning due to seat heater. Dealer corrected issue but issue persists. Not able to turn heater on. Dealer claims issue is fixed but when heat seater is turned on, burning smell and smoke fills car. Advised dealer that car is leaking water in since noticed water on the truck in the rear where the computers are. Once water is in, all sorts of electrical light issues happen with the car. 2) car is having transmission issue. Upon research, it seems ML350 has this recurrent issue. Cannot understand why Benz is not having this recall. Car stops moving in the middle of highway. Cannot get it to run. Have to turn the car off, push it aside and try multiple times for car to move.this is extremely dangerous with kids inside truck since that is the reason why I bought truck for over more than 35 K. dealer claims its a transmission cover valve body but does not guarantee repairs. Dealer states even after this repair, the issue could persist and transmission needs to be replaced which could cost another 4000 usd in addition to 2000 to change plate. It is obvious Mercedes Benz has let us down and also has made it dangerous for us to drive their cars. Please investigate this issue. If you go online, everyone with this truck is having this issue and is shelling dollars out to Mercedes dealers for fixes that are not guaranteed.
