2012 Mercedes ML 350
2012 ML 350 transmission issues

Driving to work few days ago all freaking lights came on the dash. Pre-safe inoperative, ABS, Parking Brake, Do not shift gears Visit dealer, check Engine. I turned the car off and on and they still pop up...all the error msgs. Now it wont start at all. I ended up towing it to dealer. Got call from "stealer" they said blind spot harness is bad with parktronic harness. They gave me estimate 2100$. I still doubt that there is a issue with same harness.Anybody ever had similar issues. All the help is appreciated. And yes it went into a limp mode also. 66k on odometer

An excellent alternative would be to have your dentist or ex wife diagnose the car!!

What do those harnesses have to do with the transmission? Sounds suspect to me.

Check out the link below to view the section on what causes the car to go into Limp mode. One of the causes is just as simple as a failing battery or alternator. That would explain why all the warning lights came on too, and also since the car is a 2012, the battery if not already changed, is due. Note that there are 2 batteries in an ML.
