1 Exterior Lighting problem of the 2012 Mercedes Benz ML350

Failure Date: 06/05/2024

Steering column module is intermittently not working as intended, therefore the blinkers will sometimes not work causing it to be a safety concern if I can not signal where I am going. When looking this issue up online I have seen numerous different forums and posts where people have had the same issue. When I took my vehicle to the dealership they had told me that this is very common with the vehicle I have and they do the fix all of the time, just for the issue to happen yet again later down the road.

Driver side low beam headlight turns off and on randomly whether the vehicle is off or on. I lose view of the road because lights turn off randomly and others cannot see me at night as well. I've tried taking my vehicle to the shop, but no one can trace down this problem. No warning was shown until recently.

4 Exterior Lighting problem of the 2012 Mercedes Benz ML350

Failure Date: 01/01/2023

The steering column does not operate properly. The column no longer adjusts positions and more importantly, the turn signals work ad-hoc. When you start the vehicle, the turn signals tend to operate properly; however, after driving for approximately 15 minutes, the turn signals operate sporadically. This is a safety concern as it's impossible to know when the turn signal will operate correctly or not, thus creating a hazard to me and others on the road. It is my understanding from investigating this online that this is a systemic issue with this model and not unique to my vehicle (just google "2012 mercedes Ml350 turn signal problems"). I discussed this with Mercedes Benz USA and they told me that the only way to resolve this issue is to replace the steering column (part #: 166-460-62-00) at the cost of $3,373. 81. I hope that the NHTSA investigates this further as mercedes-benz has decided to ignore this safety issue that may cause harm or death.

5 Exterior Lighting problem of the 2012 Mercedes Benz ML350

Failure Date: 12/09/2022

Due to water in the spare wheel well, (recall id:22v955) our fuel module and fuel pump went out. While driving in traffic on I-5 our car stalled then stopped which put us at risk of a crash. The first time (July 2022) it was repaired by cooper's auto repair), after the 2nd time it failed again in Aug 2022, once again as we were driving, our mechanic at (boyle's foreign car repair) Aug 2022 & Dec 2022 (replace) decided to do an inspection of the whole car to see why this was happening, upon inspection he found water in the spare wheel well, he pulled out the plug to stop accumulation. 2 months later (Feb 2023 )we received the recall letter. In the letter it states that mbusa would reimburse repairs performed prior to the recall. Mbusa is now refusing to reimburse for replacement but also refusing to find and fix where the water in entering. We reside in a very wet part of the country and see this as a continuing issue. There also is condensation in the back tail lights, which was not there until this issue started occurring. The car was previously in s cal so there was no issue with water accumulation until it was moved to the rainy pacific NW. We are fearful of using this car during very wet times as we do not know if this (failure of pump/module) will occur as well as condensation and water being in the back tail lights possibly resulting in the car stopping during it being driven. Therefore putting our lives in potential danger of an accident.

6 Exterior Lighting problem of the 2014 Mercedes Benz ML350

Failure Date: 01/26/2022

After driving the car, the right/left turn signal switch fails to work (no signal is given both in the panel of the car and the external turn signal lights do not flash). However, the emergency flashers still work. I have searched the issue and found many occurrences on the internet. Such a common issue should be a manufacturing quality issue and deserves a recall.
