EXTERIOR LIGHTING, ELECTRICAL SYSTEM
The turn indicators stop working suddenly and randomly giving inaccurate/false indication to the driver of the vehicle that indicators are turned on and no indication of turn signal to the other drivers that can be hazardous especially at the 4 way stop signs where other drivers are assuming that vehicle is going straight where as the vehicle is intending to turn left but it is doing it without the indicator due to sudden failure of turn signal indicators and during lane changing. The hazard warning continues to work just fine and the turn indicator functions return to normal after turning the ignition off and back on. The occurrence of turn indicator failure is quiet often and has no set pattern.

SERVICE BRAKES
Brakes failed without warning. Repair shop removed the covering over brake lines and said they were rusted through. Towed to Mercedes dealership thinking it was part of recall and they said it wasn’t only the brake booster. Said nothing about rusted through brake lines! Someone’s going to get seriously injured driving not knowing their brake lines are rusted through.

ELECTRICAL SYSTEM, ENGINE, STRUCTURE:BODY
After a weekend of incessant rain, while driving a short distance (10 minutes) , this low-mileage, well-maintained 8 year old SUV suddenly stalled, Engine appeared to have powered down and the yellow Engine light came up and pressing gas pedal didn't do anything. I was fortunately able to press the Power button once frantically and re-start it once more and pull over to the side but the car refused to power on thereafter. After investigations by the shops, it appears there was water leaking "through" the body of the vehicle and into the area below the interior of the car, short circuiting Fuel Driver and stalling the car (which they subsequently repaired after draining the water and replacing/re-programming the fuel pump driver) before handing it off for the leak identification work. The car was subsequently taken to a specialist shop to figure out the leak, and they are unable to identify any reasonable source of the water leak and insurance is so far claiming this is "wear and tear". In the course of the testing, the *same* issue happened again and the car stalled while driven by the shop personnel and they could hear the sound of water inside the cabin all the way up to the front. They are unable to identify the source(s) of the leak and at this point, the car has been unusable for over 4 weeks as Insurance continues to push back and the shop can't do the additional work to identify the source in the body without insurance approval. I made attempts to contact the manufacturer but their only available contact is their Customer Support (no email/chat option) who refused to discuss this as it didn't pertain to them directly and re-directed me to talk to my own insurance company. I even reached out via Twitter but got no response. This expensive luxury SUV is not just unreliable at this point but *dangerous* where there are mysterious water leaks under natural conditions like rain leading to car stalling while in motion.

STEERING
Steering wheel tilt adjustment failed. Without adjustment it is impossible to steer the automobile safely due to hand placement for control. This is apparent especially when there are multiple drivers. There is not a manual over ride since the system is controled electrically

EXTERIOR LIGHTING, STEERING
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.

SERVICE BRAKES, STEERING
On February 18, 2022 at approximately 2240 hours I was in a wreck which totalled my 2010 Mercedes ML-350. I was approaching a curb and tried to brake but they didn't work and my vehicle pulled to the right and I totaled it out on an electricity pole. I was not aware of the recall 16V081 until September 04, 2022. My mercedes is currently under a tarp under my shed, and has been for months. Please explain the steps and procedures I need to follow to get my vehicle replaced because the damages to my vehicle as well as the transformers that blew, shutting off power in a 2 miles radius could have been fatal and I have since been without a vehicle.

STRUCTURE:BODY
Neither back doors on my 2015 ML350 lock. Even after you try to lock them from the inside anyone can open the doors from the outside. This is a huge safety hazard because someone could easily car jack the car while you are in it. I bought the car new from the local dealer and i have reported this to the dealership and they said it was a known problem and that acutuators on both doors needed to be replaced at a large cost to me. I wrote to Mercedes Corporate to report this and to ask for financial assistance in trying to get it corrected and was told to just report it to you. Thank you for any assistance that you can provide.

ELECTRICAL SYSTEM, LANE DEPARTURE: BLIND SPOT DETECTION
The following has been happening over the last 2 - 3 yrs. Also confirmed with other customers on MB world blog site. After traveling in the car for 5-15 minutes, and sooner if connected to cell phone via bluetooth, the indicators stop working. This leads to deactivation of the blind spot assist as well. The problem is temporarily resolved after switching the vehicle off and then on again, only to recur after driving it again for 10-15minutes, and earlier if attached to iPhone via Bluetooth. The blind spot assist is then permanently inactivated. 2 Mercedes dealerships in 2 separate states where I took the vehicle could not even identify a problem, let alone resolve it. When I called MBUSA, they claimed ignorance to the issue and told me to repair or change the vehicle myself. Since this is an issue with multiple vehicles, a recall needs to be issued for this model. It’s unknown how many collisions can be attributed to this since the problem has not been acknowledged by Mercedes’. The problem has occurred almost everyday over the last 3 years. I have narrowly missed being involved in collisions because of the inactivation of blind spot assist and changing lanes. I have almost been rear ended a bunch of times because of the indicators getting inactivated. All this has happened with my family traveling me with. Please lets not wait for loss of life before a recall is initiated. thank you.
