VISIBILITY/WIPER
My car's windshield at first started to leak. I took the car to the dealer and was informed that leaky windshields are not covered by the warranty. I took no further action as we were still in a COVID restricted environment and the need for the car was low. As my company started to return to the office I have begun using the car more and have now observed that windshield adhesion to the frame has now deteriorated. The car has approximately 41K miles at which I would not expect the windshield to be unglued. I was also recently made aware that there is a similar problem affecting other MB 2020 vehicles, which I do not find to be a coincidence. My car will now require a full windshield replacement and MB is refusing to discuss it.

ENGINE
The 48 volt battery on this mild hybrid vehicle failed and the car was unable to be started on May 3, 2021, with 196 miles on the odometer, a mere 15 days after delivery. It had to be taken by flatbed to the dealer where ultimately the 48 volt battery was replaced. Then again on June 5, 2021, the car was again unable to be started, with a mere 735 miles on the odometer. Again, the car had to be taken by flatbed to the dealer, where ultimately the 48 volt battery was replaced a second time. While both failures, fortunately, happened while the vehicle was at home, the could have happened on the highway, in the middle of nowhere in bad weather conditions, or anywhere. I have had to cancel a cross-country drive for fear that, once again, the 48 volt battery will fail, leaving us stranded anywhere or, worse yet, in the middle of a highway.

UNKNOWN OR OTHER
My husband and I were driving on the interstate in Indianapolis, Indiana yesterday, November22, 2021 and out of the clear blue our sunroof exploded on our 2019 Mercedes Benz E300W4. This was not due to being hit by something and we were not near an overpass. It exploded from the center outward. This experience scared me to death as I tried to maintain control of our vehicle in the multi lanes of traffic. Glass fell from the sunroof into our back seat which was another concern. Thankfully, we didn't have our grandchildren with us. We immediately headed to the Indianapolis Mercedes dealership where I got the car for service. They told us that it was not covered under warranty due to the damage being glass. They then told us to contact our insurance company for help. They were absolutely no help to us and seemed to brush us off as quick as they could. We are scheduled to have the sunroof repaired next week, however, now I'm a week without a car to drive, and the cost of the repair is estimated to be upward of $2,000. I have completed some due diligence on this, and found that there has been a class action lawsuit filed February, 2021 against Mercedes Benz over this same defective problem. Let me know if you have any other information or assistance for me regarding this issue. Thank you!

FUEL/PROPULSION SYSTEM
Vehicle emits a strong odor of gasoline when cold. It was mainly noticeable on the outside of the car at first, but now when I turn on the air inside the car (not on AC mode), I started smelling the odor of gas in the cabin. I have taken the car for possible repairs, but am told on two separate occasions by an independent service center that the odor can not be duplicated. There are recalls for the same issue on different models, but as of yet, not on this particular year model. I have notice that when the car sit overnight and when I open any door, trunk or push the lock button on the car's remote, a few seconds later, it starts emitting the smell of gasoline. The car is always parked overnight inside my garage, hence the smell is very strong.

AIR BAGS:SIDE/WINDOW:HEAD:CUSHION
Stopped at a stop sign and the passenger side seat headrest deployed. Luckily no one was sitting in the seat at the time. This car has the Neck Pro Active Front Head Restraints. The plastic that holds the headrest in place fails after time. There is a class action lawsuit against Mercedes and the manufacturer of the plastic piece Gammer I believe. This failure has caused injuries to people that have been sitting in the seat at the time of deployment for no reason. This is a safety hazard as if it goes off while driving can cause you to loose control of the car and injure anyone in the car as well as other people if you were to get in an accident with another vehicle. This should be a recall.

Specific component is Oil leaks from transmission wiring harness and ECM connector. The leak is from camshaft hall sensors and transmission drain plug.

WHEELS, STEERING
I bought this 2018 e43 amg at 24k miles ,still under warranty ,and when I first told by dealer that there's a crack on my wheel I have to replace it ,I thought it was my driving even though I can't think of getting in a pothole whatsoever,so I shop around and found a random shop ,they showed me a picture of the exact same car of same year with the same problem on the same size 20in wheel ,crack on the oem wheels , I was thinking this is strange ,but I choose to trust the mb quality. Later on there's a noise coming from back seat ,I went to dealer and try to find out ,they did a good job found out they need to replace the whole rare end,and also found 2 wheels bent including the new wheel I just replaced,and another crack on one of the rare wheel which I think caused by the rare end issue ,and they did ,but the very second day I got my car back ,the noise is still there and getting worse ,Itried to contact the advisor to find out what's going on ,but he hangout on me and never call back ,I don't want to take any risk for them to say it's my driving that Hurst the rare end again which I drove really carefully,so I had to go back to dealer on the same day and have it quick checked ,the same advisor talked to me saying we replaced with the item that we ordered from mb directly and makes me feel like they are trying to blame me ,and using we don't have loaner car , it's gonna take a long time ,we are busy kind of excuses to make me go away but I insisted to have it checked,after 1 or 2 hours ,they told me they gonna order another rare end for me without telling me what's wrong ,but still let me drive it home . They noise and shaking is becoming worse only after 200 miles I was driving,so something wrong with the rare end of 2018 e43 amg and wheels too. With 1 whole rare end ,2 new wheels , still, problem not solved at all.

Re-Seal Upper Timing Covers of the cylinder head timing covers are seeping. 2016 E350 has less thank 19k on it. The fluids can potentially leak onto the roads causing a hazard, it is also a fire hazard, as well as an environmental issue. This was identified by Revolution Mercedes in Decatur, GA. After reading some forums, I have seen where others are having similar issues and believe this should be addressed.

SUSPENSION
Rear K Frame front part has completely rusted out. Mount ripped trail arm. Both rear tires were ready to shoot off. This was confirmed by a mechanic when the car was being serviced after the check engine light came on one day before taking it to be serviced. The car is not drivable. It only has 60,000 miles on it. It was always serviced at the Mercedes dealers. It appears as a defective part.
