Body problems of the 2014 Mercedes Benz ML350

Twice in the last few weeks my tailgate has opened while driving the vehicle. Prior to this, the tailgate has never dropped while driving since the vehicle has been new. The tailgate was not down whenever I left, but it was down whenever I got to my location. I did not hit the tailgate button to drop the tailgate at any time before during or after this trip. On the one occurrence, items were lost from the bed of the truck, which could cause a road hazard for other motorists. There were no warning lights or notifications that the tailgate was open on the driver information center or elsewhere. I have service scheduled with the dealer on 5/2/25 to inspect the vehicle. I am unsure at what point in the trip the tailgate opened.

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.

In my neighborhood approaching a stop sign about 20 yards away. The car all of a sudden accelerated at a high rate of speed. I was going too fast to make the right turn and the brakes did not stop the car. I ended up running through the stop sign up an incline and into the woods hitting multiple trees before coming to a stop. This caused over $18,000 damage to the vehicle (not including damage to the under carriage). Not only was this pretty frightening but what could have happened if I wasn't in my neighborhood when this took place could have killed somebody. It really shook me up. Thank goodness there were no kids at the bus stop. I was also surprised that the air bags did not deploy. The insurance company totaled the car so no one really seems too concerned about the cause of the unintended acceleration that totaled my car while driving in my own neighborhood! this should not have happened. I hope someone will care enough to try and determine what happened so this doesn't happen to someone else.

Power sun roof is coming off the tracks of the roof which it is attach to. I feel this is an extreme safety hazard because I believe it will eventually come off my vehicle and cause a serious accident flying into another vehicle or even a pedestrian. This was fixed by Mercedes Benz [ benze busch of NJ ] back in to 2018 and now it is doing it again. I contacted the dealer again about this and they refuse to repair saying vehicle is out of warranty. I also contacted Mercedes Benz corporate headquarters and they refuse to acknowledge the problem. Obviously this is a defect in the vehicle. I researched that they have had similar problems with other vehicles sun roof problems and they acknowledge those facts and repaired them. I previously filed a complaint with the NHTSA id #11478665 but it seems that you didn't have all the facts. Please look into this matter again now that you do. Thank you.

I was in a collision in which I rear ended another SUV. The speed control did not enable and I hit the other vehicle hard enough to cause $20,000 worth of damage to my car. I believe the car braking response was slow and the airbag should have deployed in a crash that significant, but it did not.
