Mercedes-Benz ML350 Problems

Delay before crank start and no starting.

Car has left me stranded, where key is in the on position but nothing registers and only auxiliary electrical works (stuff that works when no key in ignition.)
This problem started occurring after a service interval where half a dozen error messages required some steering parts to be replaced.
Knauz Mercedes kept the car for a week and could find no fa...

Loss of Power Steering Due to Leaking Steering Rack

It is not uncommon for the power steering rack to develop a fluid leak requiring replacement of the rack assembly. Loss of power steering fluid may also cause an abnormal noise and damage to the power steering pump.

Rough Shifting of Automatic Transmission

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

Mercedes-Benz ML350 Reviews

I bought a 2012 ML350 bluetec in 2015 with 38,000 miles. The driver's side seat belt does not always work and the cigarette lighter does not work at all. The rear brakes had to be replaced at 52,000 miles at a cost of $800. Now, at 68,000 miles, the oil cooler is leaking and will cost over $5,000 to repair. The vehicle is out of warranty and the extended warranty I purchased will not cover th...
This car has been nothing but trouble and a money pit. I have spent over $5000 in repairs in the last 2 years. Would not recommend this make and model to anyone. Had issues with crankshaft and alternator-replaced twice. In the shop now becuase check enging light came on again..waiting to see what is wrong and how much it's going to cost.
I bought a 2005 ML 350 brans new special edition and it has not given me trouble at all so far. Now it does have a steering wheel fluid leak that has been the main fault that was repairable. The car has been working like a dream so far compared to any car of that age. It has run 188,000 km.
