1 Seats problem of the 2008 Mercedes Benz E350

Failure Date: 12/16/2025

2008 mercedese350 (w211) driver’s seat heater, ~11:48am location: lidl parking lot, 2017 st. Joseph’s dr. , bowie/upper marlboro, MD while I was sitting in the driver’s seat with my back fully against it, the seat heater burned through the leather on the left side of the seat. The cabin immediately filled with smoke. The burning stopped only after I turned off the seat?heater button. I was inside the vehicle during the failure, and the situation created a direct fire hazard; the seat could have ignited, and I could have caught fire. I don’t know if the passenger seat heater is also affected, so passengers cannot safely use their seat warmer. No warning lamps, messages, or symptoms pre failure. Evidence available: video/photo of the aftermath (burned seat left?side damage), the vehicle and damaged seat are available for inspection. Smoke in video/photo. Has the problem been reproduced or confirmed?: I’ve not attempted to reproduce the problem for safety reasons, and it has not yet been confirmed by a dealer or independent service center. However, publicly available information shows mercedes previously settled a $54 million class action for the same seat?heater defect in model years prior to 2008. My 2008 model was not included despite experiencing the same dangerous failure. Mercedes is aware this is a known issue. Has the vehicle been inspected?: a dealership inspection at mercedes?benz of alexandria scheduled 12/23/23 at 11:00 a. M. Warning lamps or prior symptoms: none. Safety risk summary: this defect created immediate danger to my safety. The heater burned through the seat while I was sitting in it, filling cabin with smoke and creating a risk of burn injury and the possibility that I could have caught fire. The defect may also endanger passengers if both seats are affected. Broader concern: prevent others from experiencing defect, causing serious injury/vehicle fire. Limits safe use of vehicle for self and passengers. Plus mercedes is aware. Can’t upload video.

6 Seats problem of the 2012 Mercedes Benz E350

Failure Date: 07/06/2024

I am writing in regards to the 5 vehicle recalls that were for the make, and model of my car that is showing as having no recalls for. The recalls involved air bags, air bag software, fuel filter flange, and I am also wondering with the driver headrest deployment module if that is associated with an airbag module; as when I had purchased the vehicle I had found out that both my airbag modules had malfunctioned with showing the srs lights on the dash. I was told that mercedes of sarasota, FL had replaced the passenger airbag module by mercedes of south orlando. When asked for a printout verification of this repair showing to be completed; they said they couldn’t provide me with this information. As proof of the service to being completed could not be provided. I had tken my car to their to have them look into this, and the tpms sensors showing malfunctioned; communication error message, and they couldn’t figure out what the problem was causing this. I had to take my car to an auto electrician to find out the problem; that I had found out that a 100 amp fusible link had blown, causing all those problems with also the roof wasn’t working. Along with I was smelling fuel. I found out about the recall for these items after getting them repaired out of pocket by the auto electrician mike from peak audio, and electric, and as to the fuel filter flange I had to pay like $1,200 to replace as they had replaced the fuel level sending unit that include the fuel filter flange. I would like refun; still have the headrest driver side that needs to be replaced. I found out that their is an recall for this make, and model of car that had said the air bag deployment software was under recall for those vehicles; which I believe could have triggered the deployment of the head rest while I was driving; as if I had been near a car; I could have been involved in an accident. I think that this should have an open ticket for repair placed on all 2012 mercedes E350 cabriolet blue efficiency.

7 Seats problem of the 2012 Mercedes Benz E350

Failure Date: 11/28/2023

The car was parked in the driveway outside. In the am when getting into the car I saw that the drivers head-rest had engaged by itself during the day. There was no airbag only pieces of plastic and springs on the seat. The headrest was just hanging there and in no way could be reset. Car was taken to the dealer for repair. Extended warranty would not cover it stating airbag issue even though the headrest has no airbag. Dealer is repairing the headrest - total cost $1,800. Mercedes also does no want to cover it since the auto is a 2012. The problem was reported to mercedes and they stated that there was no recall on the item. And that is it. Spoke to dealer who indicated that they have seen this problem before but not widespread. And that is it!! mercedes quality is one to be desired.

10 Seats problem of the 2012 Mercedes Benz E350

Failure Date: 06/01/2022

The chrome handle on my driver's seat is peeling off and very sharp. It cut my inner wrist really bad last week. I searched online and found many people having the same issues. I was quoted at around $400 to fix this one little handle and I don't have that amount of money right now. This is serious danger and needs to be fixed immediately and it scares me to think of doing it again and cutting into the artery or nerves in that area of my wrist. 1) yes, you can inspect it or I can send pictures in. 2) the risk it puts on me is cutting my wrist and/or hand, infection, stitches, pain, not being able to work, nerve damage, medical bills, etc 3) there are many accounts online of people experiencing this same problem. I'm surprised someone hasn't gotten seriously hurt from it already. 4) it has been inspected by a service and repair center that immediately told me to be very careful due to the high possibility of cutting me 5) no warning lamps or messages.

Failure Date: 10/23/2020

The car will sometimes think there is someone riding in the passenger seat when no one is there. It causes the seatbelt light and the warning beeps to occur. Its a safety hazard because its a distraction while driving and it would set off the airbags for that side of the vehicle if anything is to happen.

20 Seats problem of the 2008 Mercedes Benz E350

Failure Date: 11/06/2018

Driver's heated seat burning?!? I've owned this vehicle since late may of '18. On tues. 11/06/18 after work, I started the car and began driving home. Turned on the heat and the driver's heated seat (it's 30 degrees and snowing here in mn). I take-off and not a minute later I smell what seems to be an electrical fire/smoke. There was likely even a whiff of smoke present. Thankfully I immediately figured it was unfortunately coming from my car and that the heated seat was likely the culprit. Turned it off, pulled over and noticed the pics attached (burned hole in lower right of seat if looking at it head-on). There was the mb-tex crack there prior. Now, I won't (unfortunately) be using my heated seat anytime soon, but my question is, what now? the wife uses her side all the time, never noticed any issues. Pretty scary/surprising and disappointing all at once.

26 Seats problem of the 2010 Mercedes Benz E350

Failure Date: 12/01/2015

At 5 years my front heated seats stopped working and the drivers seat ripped across where I thought there was a seam. After researching other 2010 E350's with mb tech seats, they all appear to have the same problems. I have contacted mbusa many times in the past 3 years and have received no answer or solution. If you also look at ads of these vehicles for sale by owner, you will see the same issue. The only people who drive this car are; me and I'm 135lbs and my mother 93lbs, so we are not over weight and putting extra stress on the seats. This car has been well maintained and has always been garaged. When parked in a lot for shopping, shades on the windows are always used. I can provide photos, but not from the computer I'm using.

28 Seats problem of the 2006 Mercedes Benz E350

Failure Date: 04/30/2015

I am a disabled veteran and on April 30, 2015 my car smelled like gas. Mercedes benz USA said to take it to nearest dealer atlanta classic cars in gwinnett county, GA. The problem: leaking fuel tank, it took 120 days to replace the tank. The car still smells like gas, the dealership recommended replace the seat cushions, and the felt. Both are wet from gas, and has gas vapors on it. The technician showed me how to lift up the seats, and I took pictures of the wet seat cushions, and the wet felt. The dealership wants to charge me $565. 00. My complaint is that I should not have to pay for a problem that I did not cause; this was caused by a leaking fuel tank. My throat burns from the gas smells, my eyes water, and I'm getting headaches. Part of my disability is asthma and the fumes in this car exacerbates the asthma. I called Mercedes Benz USA and they said unfortunately they covered just the part! this is horrible, and dangerous to ride around with wet seat cushions with gas on them. I cant believe mercedes is not standing behind their product. This is a firetrap and they should be responsible for replacing the seat cushions and felt at no cost to me the consumer!.

34 Seats problem of the 2012 Mercedes Benz E350

Failure Date: 07/29/2012

The interior dash vents (shiny items) are reflected unto the side mirrors making it dangerous when changing lanes because one cannot be sure what one is seeing in those lanes because the reflection is very pronounce. These vents and other dash items are also reflected on the windshield, almost like an obstruction when one is driving. In addition, the adjustable front seats, are so uncomfortable that one is constantly adjusting the seat setting while driving. These issues can cause quite a distraction and are obviously dangerous. When we reported these items to the dealership, mbcharlotte, and mbusa, they took no action. If there was ever an accident with this vehicle, and the cause and effect was related to these issues as contributing factors, how can one ever prove that they caused the accident or contributed to the cause. One would need a whole lot of experts to show that the manufacturer build in the problem by not addressing it, or testing for the effect that these issues cause the driver('s). One of the dealers product expert, solution to the reflection problem was to roll down the windows when driving to get rid of the reflections. The individual who sold us the car, [xxx], tells me, now, that he notices this reflection on all these cars. The dealership is indifferent about these items brought to their attention. Even though they, in our eyes, are safety issues. Hopefully NHTSA can look into this and can do something to resolve it. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
