AIR BAGS, UNKNOWN OR OTHER
A warning saying Front Right Malfunction Service Required. I took my vehicle to a mercedes dealership to have my vehicle inspected. I was told that the Airbag seat cushion/weight sensing control unit all needed to be repaired/fixed. I have an extended warranty but this was not covered. I was told my Airbag might not be deployed if I was involved in an accident and someone was in my front passenger seat. "No one should ride in the front passenger seat until this situation is taken care of." I feel strongly that this should have been covered, plus it should've been a recall on this. It's a real safety issue!!! This need to be on the recall list for all mercedes or other vehicles with this particular issue.

SERVICE BRAKES
Rear subframe recall and brake lines. I am very disappointed and frustrated right now. 2013 e350 has completely corroded brake lines on an otherwise relatively rust free car. The vehicle is due to get the rear subframe replaced as part of the warranty extension. The brake lines are not covered and are 4,000 dollar additional fee to replace. I can’t get the work done anywhere else for cheaper because the rear subframe needs to be dropped in order to do the brake lines, making it cost prohibitive to have the subframe and brake lines done at different shops. Something is wrong with the brake lines they used when building this car. I’ve owned cars with 10x more rust and perfectly in tact brake lines. Frames rot away before I see brake lines this bad. They should have extended the warranty to the brake lines and I hope they do so I can get reimbursed in the future.

FUEL/PROPULSION SYSTEM
I have a 2012 E350 with less than 95000 miles and I see these vehicles were recalled in the past for their fuel tank manufacturer malfunction but my VIN number was not included. This car went numerous times to the mechanics and the fuel components fixed but it still leak gas and smells even when I do not drive the car. I spent over $15000 on this matter. This is now becoming a safety issue for me and my neighbors. I don't know what to do. Here is what happened. All began February 2023, I towed the car to an approved MB mechanics who said fixed the car. 9 month later, I brought the car back for the same issue. Strong fuel smell. The attachments for repairs will show the work done. Some repeated and recharged to me. The following year April 2024, I woke up one day with a fas leak all over my drive way and a strong smell of gas. I had the car towed for a repair cost of $7754 total. I am constantly having the same problem with the car and wanted to alert here to bring Mercedes Benz awareness to their faulty parts putting consumer lives at risk.

EXTERIOR LIGHTING
The instrument panel that displays the digital speed, warning lights, etc. went black suddenly when turning on the car. It came back on suddenly while driving on the highway but after the car was turned off and restarted, the instrument panel has remained black. This is a huge safety issue as there is no warning light indicators, merging lanes does not signal if another car is present, among many other concerns. The vehicle has been inspected by mechanic. There was no warning indicators that instrument panel would go black suddenly. It happened in February 2025.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER, ENGINE
Recall exists related to a potential issue with the high-pressure fuel pump, which could lead to engine stalling and increase crash risk. My 2012 Mercedes E350 stops the engine in the middle of the road couple of times and for some reason, its stops or shut off the engine completely. The last time I was pulling out on the main road and stop right there. I made a big traffic, and I was scared because I cannot start the car. The guy stops and help me to push out of the road, but we cannot push the vehicle unless someone is inside the car. If I go out, it will automatically go on "park" and cannot push the car. When you check the dashboard the check engine light is not on. 2nd incident I bring this car to Mercedes Benz Dealership, and I told them that there is something wrong in my car, I explain what was wrong but, the guy I talk to, told me that if the check engine light is not coming on, my car is fine. I repeated that the car stops ones in a while when the temperature light is on inside the dashboard and the engine shuts off. He told me if the check engine light turns on then I bring it back. I show the code reading but the same thing he said. I left and went back home and suddenly I get stranded again; I got stock in the middle of the road for 3 to 4 minutes. I start the car and suddenly the car starts and find the nearest place to pull over. I let it call down for couple of hours and start again, the car starts and try to go back home. When I was in the interstate hwy. My car engine shut off, so I quickly pull over, but I was having a hard time to turn the wheel. I believe that this is very unsafe and should have Mercedes Dealer has to repair this issue. I research on the website that 2012 Mercedes Benz E350 have recall to a potential issue with the high- pressure pump and other things like Battery fuse relay box positive terminal and low fuel circuit.

SERVICE BRAKES
Driving home on a 30MPH street, had the brake light go on and felt the brake petal sink to the floor when I had to stop. Very concerning was grateful I wasn’t going faster. Cautiously made it home, and when I took it to the shop, they diagnosed that the brake lines had corroded. This is a huge safety concern and should be a recall as it could be fatal in certain circumstances.

SERVICE BRAKES, SUSPENSION
There was already a recall for my rear subframe that I am now getting done due to rust corroding the metal structure. However, upon the dealers inspection the corrosion is also present on the rear brake lines which cause a safety concern and are charging $4000 to replace the brake lines aside from the warranty repair. It poses a safety hazard if the lines were to fail and have heard of others having the same issue along with rotted rear subframes.
