SUSPENSION,STRUCTURE

The rear subframe is defective and subject to premature corrosion and failure of parts that connect to the rear suspension. Due to the fracturing of the joints connecting to the suspension, my car was at risk of going out of control when needing to brake at higher speeds. The way the suspension component broke also risked damage to the gas tank if the car was driven over a large bump or pot hole. The problem was diagnosed by an independent repair service. The corrosion is not visible to an owner. It does not impact any body panels - only structural parts visible when the vehicle is on a lift. Mercedes Benz has provided an extended warranty for unlimited miles and 20 years to any owner of this model for a range of years and models. This was communicated to Mercedes Benz dealerships on March 10, 2023. However, since the vehicle is not subject to recall, I do not know how this was communicated to an owner. I did not receive anything alerting me to the problem. Mercedes Benz has my phone number on file.

AIR BAGS,SEATS

Passenger seat capacity sensor fault. Will not activate passenger side air bag. Checked with obd scanner

FUEL/PROPULSION SYSTEM

Fuel odor is very apparent (while idle) but difficult to identify location. Same models seem to have recalls for fuel injectors/rails but not this specific VIN. I believe the issue might be of similar recall. I will have the car diagnosed soon.

VISIBILITY,STRUCTURE

The contact owns a 2016 Mercedes-Benz E350. The contact stated that water was leaking inside the vehicle through the seal around the windshield. The contact stated that upon manually pushing the windshield, the windshield was movable. Additionally, the contact stated that there was a windy sound coming through the windshield while driving. The vehicle was taken to Dunaway Glass Repair Company, where the windshield was being replaced. The vehicle was being repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not under recall. The manufacturer referred the contact to the NHTSA Hotline for the VIN to be added to a recall for potential reimbursement. The failure mileage was approximately 140,000.

ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE

The contact owns a 2016 Mercedes-Benz E400. The contact stated that upon starting the vehicle, there was a knocking sound coming from the vehicle. The check engine warning light was illuminated. The automatic brake and Adaptive Cruise Control warning lights were illuminated. The emergency braking system engaged independently. The vehicle was taken to an independent mechanic who determined that there was oil leaking from the gasket and was dripping onto the engine.

ENGINE

Mercedes Benz has a recall on several models including E-Class (E 200, E 220, E 280, E 350) experiencing timing chain problems. The timing chain is an important component of the engine, as it helps to coordinate the timing of the engine’s various parts. I am currently having the same issue, but my model is an (E400) which has not been included in the recall. It appears that my timing chain failing, which is causing a number of problems with the engine, including reduced performance and fuel efficiency, and if MB does not recall this model, I am facing complete engine failure.

ENGINE

Since May 2024, I had taken my car in for repairs at 3 different shops for same exact issue diagnosed as leak from air intake system. It has been repaired 7 times since it first occurred in May 2024, and unfortunately it is still not resolved. This is a potential danger to the driver because all of a sudden there will be loud noise from the engine, car will start misfiring and slow down the speed. The previous 3 attempts of repair were made at Mercedes Benz of West Covina. The car is non drivable at the moment.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE

Q1: Yes, it is available for inspection upon request. The instrument cluster showed some messages* randomly appearing/beeping on and off but there were other issues present: • Acceleration not possible in drive • At one point transmission would not shift from gear 3 • *Speedometer would go up and down randomly until it eventually stayed at 0 physically and digitally as I was going 55-60 MPH • *Check Engine light ON • *Red ‘Brake’ light ON • *ABS failed • *Distance sensors failed • *Stability control failed • *Electronic braking system failed • *Power steering failed • *Cruise control failed • *Mercedes PRE-SAFE failed • *Blind Spot Assist failed • *Lane Keeping Assist failed • *Adaptive Highbeam Assist failed • *Mileage was not displaying on the dash • Car would not shut off as I pushed the off button when I managed to eventually stop • *Climate temperature sensor reaching temps of 127 degrees Fahrenheit. Q2: I lost control of the vehicle while driving on the highway at relevant speeds. I was unable to safely stop for some time. If this had been at night, the issue would have been even more dangerous. This car has previously slammed on the brakes erroneously (no visually perceived danger of a forward collision). These previous brake slamming issues happened once in a traffic jam on the highway and once on a main road. Q3: Not that I know of or remember, no. Q4: Before this latest incident, I have previously left my car at the dealership’s workshop to be inspected for some relevant issues and concerns that I have had. It was there for almost 2 months on one occasion. Q5: There was only one warning lamp on the instrument cluster related to the collision prevention assist being inoperative. This message has been on the dash for maybe a year or more. The times it previously slammed on the brakes erroneously, no messages were on the dash.

FUEL/PROPULSION SYSTEM

The fuel pump assembly Seals leaked fuel into my vehicle and saturated the interior of my car

ELECTRICAL SYSTEM

I believe there is faulty wiring in the door speaker front passenger side. It causes crackling and humming. It lessens some when you turn ECO off. Concerned it could ignite a fire. Once told by dealer it’s caused by rain going into the door. Next time told that just to look at the problem would be around $600 because it has steel doors??
