In having maintenance on my vehicle, the dealer advised that the subframe is corroding and needs to be replaced. I searched several Mercedes forums and found a number of owners citing similar corroding subframes yet no other undercarriage components showed rust or corrosion. All owners felt that this should be remedied by Mercedes before a failure causes injuries. Forum participants suggested and encouraged to file a complaint to NHTSA for investigation.

ENGINE
I brought in my car to M1 Mercedes, Fremont, CA for service after “check engine” light was on and running rough on idle. I told them I started using ethanol (E85) fuel recently but my car is spec for that. The shop replaced spark plugs and ignition coils but the issue didn’t go away. While the car is parked overnight at the shop garage, on Jun 21, 2022, around 11pm, the engine exploded. The incident was caught on camera by the shop. The intake manifold was blown open. The car was tolled to Fletcher Jones Mercedes Fremont, CA (authorized Mercedes dealer) for diagnostic. However, they didn’t offer any solution or attempt to find out what caused the explosion. They offered to replace the intake manifold for $1200. I declined as I believe this is a serious safety issue. What happen if it explodes again? Since the cause of the explosion is not found and address. It could happen again anywhere, anytime. Fletcher Jones Fremont charged me $265 for labor and I tolled my car back home. I attempted to contact Mercedes USA via their website to alert them about this problem and seek resolution. However I never hear back from them. I hope you can help to look into this serious safety issue. Attached please find the blown intake picture and report from M1 Mercedes. I have the explosion video as well.

ELECTRICAL SYSTEM, ENGINE
Camshaft sensors and solenoid leak oil internally which then gets into the sensors electrical connector. From the the oil enters the engine wire harness through capillary action maki g it’s way to other sensors and ultimately the DME (Digital Motor Electronics). This can cause February DME to fail which in turn can make the engine stop running.

FUEL/PROPULSION SYSTEM
Fuel tank fuel leak, NHTSA Action Number EA13003 I purchased a 2007 Mercedes E Class used a few months ago, and recently I noticed a fuel leak, strong fuel smell outside of vehicle when fuel tank is filled higher. More fuel means more fuel odor. Upon research, it seems like there was a warranty extension for 15 years, and with my luck, warranty extension ran out just after I bought the car but before I noticed the problem. As fuel is a safety issue and can easily ignite, and also affects emissions, I feel like the remedy should not just be a 15 year warranty extension, but longer as cars are staying on the road longer and longer. I'm sure I'm not the only one with this issue out of warranty extension period.

SUSPENSION
Rear subframe crossmember that connects to rear suspension is cracked and rusted resulting in dangerous handling characteristics. Part is severely back-ordered due to volume of consumers facing this problem. When braking hard, car swerves to right and can cross lanes. While this part broke, the car is otherwise rust-free. Brakes have been recently updated. If this is a common complaint, there should be a recall. The severe parts back-order leads me to believe that there are significant failures in the field.

The subframe on this vehicle is broken I took it to an independent dealer and they said they have never seen anything like this on a car this old. The Mercedes dealer told me that it would cost me $5000 for them to fix it about 3 weeks ago but said it's rusting and beginning to crack. But never said it was something that needed to be addressed immediately. Upon further research it seems to be a common issue on this make and model on the right side. https://www.carproblemzoo.com/mercedesbenz/e350/2014/2014-mercedesbenz-e350-suspension-problems.php

ELECTRICAL SYSTEM
There have been three events, all the same. Each time a speaker in a door, while driving, has began to squeal, sputter and the smoke. The first occurred while sitting inside a car wash, with the windows up, obviously. I was able to open the window, drenching myself, but venting the acrid electrical smoke. The second was while driving home from a medical clinic. The third was while driving on the interstate, traveling from my mothers funeral in California to Wisconsin It was 2am, just outside of Vail, Colorado in the rain. My wife was driving, while I slept. I woke to her screaming that the car was on fire, she pulled over, taking advantage of the antilock brakes for the first time ever, striking some type of curb, ultimately not killing us, but we lost another speaker, and a tire and rim. I’m, needless to say, displeased with my expensive European wagon, but Mercedes’ does not consider melting and smoking speakers to be a safety issue. Look online, and you’ll see plenty of videos of people with the same issue.

STRUCTURE:BODY, WHEELS
Recently, I took my 2012 Mercedes E350 4Matic for an oil change and after inspecting the vehicle, I was informed by my mechanic that the car had a rusted sub-frame, with visible holes near the right rear wheel. I was told this needed to be immediately addressed as it was a safety issue. He explained that if not fixed, the wheel could detach from the vehicle while driving and could result in a crash or serious injury/death. My mechanic indicated that Mercedes Benz of America is aware of this issue and they do not offer any assistance with the necessary repair. However, I did some research online and learned that if you own a Mercedes, have this same issue and also live in Germany, you can take it to a dealer for a free repair. I find it outrageous that this is not a valid safety recall and even more so, having to pay nearly 3K for the repair in order to make the car safe to drive.

FUEL/PROPULSION SYSTEM
The incident was not the vehicle persa but passengers riding in back seat experienced nausea and headaches. Found gas fumes emitting from vehicle. As time progressed fumes got worse and fuel mileage performance worsened. Gas consumption was extremely bad. Car was taken in for oil change and absolutely no gas leaks were found and technician showed me the under carriage of car. Nothing showing on the OBD. Afraid car will catch fire. Not driving as of today.

SERVICE BRAKES, SUSPENSION
This issue is pertaining to a 2014 E350 Mercedes Benz. The brake system is in jeopardy. The subframe has rotted and cracked. Mercedes Benz is aware that this is a problem for many of their vehicles. While the right side of the subframe is rusted and beginning to crack, the left side of the subframe is totally rusted and busted out. The vehicle is routinely brought to the Mercedes Benz dealership for maintenance visits. It was making cracking sound in 2021, we brought it in to be serviced for that reason on 11/23/21. This issue was not noted at that time. Mercedes Benz indicated the solution was a lube. The issue persisted post visit. The car is infrequently driven because the primary driver teleworks. We returned the car to the dealership for an assessment 8/6/2022 due to ongoing concerns for our safety. The first indicator that there was a problem was the unfamiliar cracking sound as if the car could snap in half, then hard pulling to the left when braking. There was never a warning light or any other indicator on the dashboard or otherwise. The owners initiated the visit to the Mercedes Benz dealership. Mercedes Benz reported that they did not see the rust when they assessed the car for the cracking sound in 11/2021, furthermore that the rust and deterioration happens rapidly. Had the right side of the subframe also rusted and rotted out, this could have resulted in a total loss of control over the vehicle and been needlessly catastrophic. Warning indicators necessary and routine free inspection are warranted. Repairs for the subframe alone will cost more than $4000. This is a hardship. Further, it's unclear if the malfunctioning rear left caliper resulted from the rotted subframe. The vehicle appears to be in otherwise pristine condition. Mercedes Benz has never indicated there were any issues with the vehicle's subframe despite routine class service visits at the dealership. An internet search confirms this issue is not uncommon and possibly negligible.

I've owned this vehicle for a few years and don't use it that often. I purchased it as a certified so I thought everything had been checked out. However, not too long ago i took my wife and my son who was home from college out to dinner. When we left and started back to the car, my son was ahead of us and didn't think when he lifted the door handle. The alarm came on and I was still quite some distance from the car. That didn't seem right so when we got home, I walked quite a distance from the locked car and had him try it again. Again the door came open when he lifted the handle and the alarm came on. After resetting it, I locked it again and this time had him try all handles. They all locked except the rear (passenger) door on the driver's side. That convinced me that something was wrong. I took it to the dealer, the same place I purchased it from three years ago and they said the door lock was bad and it would cost me $800 to fix it. I thought that was a little steep and told them it was probably like that when i got it. That didn't mean anything to them. I am thinking of trading the car so I don't want to spend more money on it so I told them to hold off. I was searching for that problem on the Internet and I ran across a recall notice that identifies that same problem on the same door in a number of other model Mercedes, and I thought, that seems like a coincidence. What are the chances of that? The same manufacturer, the same year, the same problem on the same door. Only the model is different. Can someone check to see if there were any problems recorded for the E300 on bulletin 17V816000? It was on Mercedes recall 2018010009 I have not checked to see if the door locks when the doors auto lock above 10 mph because I didn't want a chance for an accident.
