 Vehicle has been in to Schumacher Mercedes in Scottsdale more than 6 times since it hit 20k miles. ESP Failure. Excessive play on the Steering. Gears Slamming into wrong gear. This van is literally killing my business with how unreliable it has become. I bought the van Brand New and since it hit 20k miles it has been in 6+ times for the same repairs. Can anyone say LEMON? I am currently waiting patiently for a Mercedes Benz USA Buy back - getting ready to hand this over to a lawyer to handle while MB USA drags their feet slowly. This Van is the most expensive work van I have ever owned and it's been a HUGE disappointment.  Steering column has been replaced with multiple electronic modules and most of the time I'm limping around to my jobs in limp mode with the check engine light on. Go in for warranty repair and a week later the Check Engine and ESP Failure lights are back on. I HATE THIS VAN - it's GARBAGE!!! Buyer Beware. Still struggling with Check Engine Light every 1,000 miles. Vehicle goes back in to dealer this next week for fix number 15 CHECK ENGINE light.
