On 11/24/23 Mercedes Benz had replaced my subframe which was part of a safety recall. When I arrived home after picking up my vehicle, there was a loud bang from under the vehicle. I immediately called the service department and told them about what happened and also complained that the steering wheel was cocked to the left and pulling in that direction. My service advisor John advised me to bring it back the next day which I did. They never told me what caused the loud bang, but they did say another front end alignment was done. The vehicle still continued to pull and the steering wheel was still off center. On [XXX] I took my car to Mr. Tire for a tire rotation because the car continued to sway and jolt when going over bumps. It also made a popping noise when making a sharp turn. Then on [XXX] as I was driving, the car pulled or slid to the left. In order to keep from crashing into another vehicle, I pulled the wheel right causing me to run over the medium and almost crashing into a building. I was extremely shook up and in disbelief. Has this type of thing ever happened to anyone else before after the subframe was replaced? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving on a highway approximately 65 MPH. Had to break fairly hard due to unexpected traffic. When breaking, my car fishtailed and I thought I was going to hit the vehicle in front of me. I immediately took my car to my independent, Mercedes-certified repair shop. My mechanic informed me that it was a problem with the rear subframe. I then took it to Mercedes for an inspection. They confirmed that the rear subframe was rusted and needs immediate repair. I was told not to drive the vehicle as it is extremely unsafe. Mercedes is aware of this problem. There was a class action lawsuit filed in February of 2023. Mercedes supposedly informed owners of the potential problem, but I was never notified. I only became aware of this dangerous subframe problem as a result of this incident.

The rear sub-frame involving vehicle stability under braking and turning. A component that should remain attached to the vehicle has broken off due to corrosion. My vehicle is not that old that a key structural component of the car should break at the weld/attachment point. I have video of this defect. But its greater than 10MB and will not let me upload it is there an email I can send it to ?

2014 E350 with 41,000 miles. Rusted subframe and was informed that it represented unsafe and risky driving conditions. Reported this to manufacturer as, apparently, it is a very common problem with certain Mercedes classes. No recall and very expensive fix ($4500)! Not my idea of a safe and reliable car, as Mercedes likes to advertise. Consumers should not be responsible for manufacturing defects/ poor quality of materials used..... and should definitely not be exposed to unsafe conditions when operating their vehicle!

Mercedes Benz E350 2014 - Panoramic Sunroof rattling and squeaking noise/sound: This issue has been reported by many online, and it is a well known problem with E350. It starts with a little bit of squeak and metallic rattle noise here and there, and then after a year or so it is almost happening all the time as you drive the car. Dealer states that Sunroof Frame bolts have to be retorqued and loose bolts which rattle around have to be put back on. Estimated cost $712. If not a safety risk causing Pano sunroof to eventually fly off, it should definitely be a recall as many E350 owners have reported the same issue, and it is a manufacturer defect.

Trunk has opened 6 - 8 times on its own. In just over 5,000 miles of ownership and two documented attempts to repair the problem persists. The trunk opens on its own in nearly any combination of; in motion, stopped, in gear, out of gear, moderate speed (40-50 mph), low speed (a crawl) cool temps., warm temps., top up, top down. I have even tried, while the car is in motion, to deliberately open the trunk with the key fob and with the door mounted release. It did not open when I tried to replicate an unintentional opening. Most recent incident, 10/24/2020- while in my garage, temperature cool ~ 65 degrees, key in ignition engine and running for about 1-2 minutes, both car doors closed, putting on seat belt, emergency brake still on, still in park, heard the trunk pop open. Confirmed the open trunk in the rear-view mirror. The eight + months between this occurrence and the last attempt to repair is misleading as the car's been driven less than 500 miles between the last repair and when the trunk opened on its own this time.

I was driving the car down 880 until I suddenly heard a cracklings noise coming from the back of my car. I had just gotten the car serviced a week before so this was very unpleasant and surprising. I ended up turning back and parking my car at home. The next day while driving to the dealer I still heard the noise and there was a weird burning smell. The noise continued even after shutting off the car. I went to the dealer and they diagnosed that the right passenger speaker had melted and they also changed my amp. In my dealer notes, it states that there have been multiple occurrences yet it seems like there is no recall.
