FUEL/PROPULSION SYSTEM
My car has smelled like gas for the past few years. Also it has not past inspection for the past 2 years. Mercedes said it was due to a defective intake manifold. Paid to replace the intake manifold and Mercedes said 2 new codes appeared. Now the gas tank, fuel pumps, brackets and hoses need to be replaced at a cost of of over 3500. The fuel pumps were replaced in 2014. Not sure why I continue to have problems with fuel pumps and now gas tank. Was informed this year after replacing the intake manifold that there was an extended warranty that concluded December 2022. I think Mercedes should resolve this as other vehicles had this same safety issue.

STEERING, LANE DEPARTURE: ASSIST
It started with a humming sound in the front right wheel well and then I was driving on the freeway and my steering wheeled jerk to the right and slammed me into the side of a semi truck vehicle is available to be looked at it almost killed me. And I contacted the dealer where I bought the car from and another dealership and they both refuse to look at my car. I believe the effective component could be either the assisted steering or lane keeping and or a bad wheel bearing at manufactured

STRUCTURE:BODY, SUSPENSION
While under a hard stop the vehicle’s rear end started to swing back and forth suddenly causing loss of control of the vehicle. Mercedes Benz diagnosed the problem as a rusted through subframe which they’ve said is a “known issue” and extended the warranty on the part. The part is unavailable and there’s no ETA from Mercedes which means that the vehicle is unsafe to drive and cannot be repaired.

STEERING, WHEELS
It would seem to be the steering and related component’s including the computer. I have heard a low-pitched oscillating sound coming from the passenger front wheel well. well occasionally it would pull the car to the right, not all the time just randomly whenever traveling in the 40-70 mph range. The 2 dealerships I have taken the car to they say it’s my aftermarket exhaust, so they blow me off. the sound can be heard without accelerating and is not consistent as the droning of exhaust would be with consistent gas. This defect slammed me and my e53 into the side of a semi-truck about 4 days ago. I called the dealership I purchased it from and they told me to take the car elsewhere. so, it has not been inspected or looked at but it is available to be inspected upon request. the symptom would be the oscillating sound coming from from right wheel well.

STEERING, ELECTRICAL SYSTEM
My electric power steering failed. It often resets and can be unpredictable when it wants to fail again. It’s an intermittent problem that local dealer tried to fix with a software update but did not work. I was told I need a new steering rack at $5-6k which is unacceptable for any vehicle that has been maintained it’s whole life . My car is 8 years old with 100,000 miles with full service records I feel like this is a premature failure of the electric power steering

SEATS
Safety Issue. The Chrome on the lever to make the seat move forward to access the back seat has sharp razor blade ridges. It has cut my hand open multiple times as well as my wife and a friend. A lot of blood, this is a serious issue. When I brought my car to the Mercedes Service center the agent told me this is a known problem and he too has cut his hand open on customers cars. This is not from wear and tear, this lever is used in frequently, I see a lot of complaints on the blogs too. Mercedes will not fix it. The Part is only $270 but they want $650 to install it.

WHEELS, SUSPENSION, UNKNOWN OR OTHER
The rear subframe of my vehicle failed at the lower trailing arm mounting point (passenger side). This resulted in the car swerving to the right when I applied pressure to the brake pedal, which was worse at higher speeds. This had been getting progressively worse for a few weeks until I almost spun out on the highway while braking. The next day, I randomly got a flat tire on the rear right side while driving at 30MPH near Valley Street in Providence. There were no warning lamps or messages prior to the failure. I immediately replaced the tire and brought it to Midas on Mineral Spring Ave in North Providence, RI, so that they could inspect the vehicle. They discovered that the rear subframe was almost completely disconnected at the lower trailing arm mounting point due to excessive rust that had wore a hole in the part from the inside-out, which was not visible at the time of the last inspection. Midas immediately informed me that the car was unsafe to drive more than the distance back to my house. They also informed me that 3 tires needed to be replaced, including the flat, as a result of excessive wear on the inner wall and the inner edge of the tread. None of these three tires had reached the wear bars yet, and Midas confirmed they would not have had to be replaced if not for the subframe defect. I had the car towed to Mercedes-Benz of Warwick after Midas replaced the 3 tires (RL, RR, FR) because I heard that Mercedes had recently extended the warranty period for rear subframes (only months after a class action lawsuit was filed about the issue). Mercedes inspected the vehicle and confirmed the issue, and is currently replacing the rear subframe under the new extended warranty program for rear subframes. However, they refuse to reimburse me for the other issues directly caused by the corroded rear subframe (which they admit liability for when they replace the part free of charge), stating they have been instructed by corporate that related issues are not covered.

ENGINE
Recurrent crankshaft ventilation valve failures. Replaced 14 months ago and has failed again. This is a common and known issue with vehicles in E class from 2017 through 2019 and Mercedes has not issued a recall. Perhaps because it costs $3500 to replace it if out of warranty. Entire system replaced Feb 17, 2022 and has failed again (April 6th, 2023)
