Remedy. MBUSA will notify owners, and dealers will attach four additional retaining clips to the rubber seal, free of charge. The recall began March 6, 2015. Owners may contact MBUSA customer service at 1-201-573-5339. MBUSA's number for this recall is 2015020001.

The contact owns a 2014 Mercedes-Benz E350. The contact stated that the brake pedal was spongy while depressed, with the "Brake System" and "Low Brake Fluid" warning lights displayed. The vehicle was taken to a dealer, and the brake fluid was topped off; however, the failure reoccurred in less than 24 hours, and the same warning lights were displayed on the instrument panel. The vehicle was taken back to the dealer, and the technician was informed that there appeared to be a brake leak. Upon inspection of the vehicle, the technician discovered that the subframe was severely corroded, which had caused the brake failure. The contact informed the dealer that there was a class action lawsuit for the failure. The dealer acknowledged that the failure was a known issue; however, no further assistance was provided. The manufacturer was not notified of the failure. The vehicle was repaired. The failure mileage was 67,218.

The failure was when I hit the brakes hard in an emergency braking situation and the car very eratically and violently veered to the left. There was no warning and thank God there was no car coming in the left lane otherwise it would have been a broad side hit. I was doing 55 mph. We had the car inspected at a local shop and the left rear tie rod link was completely severed from the suspension sub-frame because of rust. The brake lines above the sub frame were also severely rusted and leaking. I called my closest dealer and they said the rusted frame replacement is covered under extended warrenty but not the brake lines which had the same issue, severe corrosion and a potential catostrophic failure! Mercedes Road Side Assistance was called to tow the car 70 miles to the closest shop.

Rear subframe rotted / corroded. Rear brake lines rotted and rear springs broken from corrosion . Mercedes refuses to address the issues under warranty except the subframe issue . Almost crashed on i-84 with child in vehicle due to rear control arm being rotted from subframe .

While braking from highway speeds or any other speed, the vehicle becomes unstable and pulls to the left, making it difficult to maintain control. During hard braking, the vehicle does not track straight and requires steering correction to remain in its lane, creating a significant safety hazard. To diagnose the problem, the vehicle was inspected by an independent mechanic. An alignment was performed, and the suspension and braking systems were inspected. The mechanic determined that the rear subframe has severe rust and corrosion. The rusted rear subframe is available for inspection upon request. Despite the alignment and inspection of the suspension and brakes, the unsafe braking behavior remains. There were no warning lights or messages indicating this condition before it was discovered. The problem has been reproduced multiple times under similar braking conditions. This condition puts the driver, passengers, and other motorists at risk because the vehicle can become difficult to control during braking, particularly at highway speeds or during an emergency stop. Based on the mechanic's inspection, the severely corroded rear subframe is the source of concern and should be investigated as a safety-related defect. I have also contacted Mercedes-Benz USA regarding this safety issue and requested assistance, but I have not yet received a response.

Vehicle subframe corrosion (manufacturer extended warranty offered). Rear brake lines corroded/leaking. Vehicle leaks fuel; steel fuel line corroded. Vehicle has about 105k miles. Minor fire started when yard maintenance came in contact with fuel saturated ground where vehicle had been parked/moved out of the way just prior. With rear suspension subframe springs corroded, vehicle bottom can contact road surface while driving, scraping steel exhaust with fuel present. EXTREMELY dangerous. Local Sunbury Ohio Mercedes dealership inspected then offered subframe replacement. Stated it was leaking fuel and not hydraulic fluid we originally thought. Brake, suspension and fuel line corrosion repairs were quoted in excess of $4,000, which was a "great deal" according to them "because the subframe would already be removed and would make it much easier."

The contact owns a 2014 Mercedes-Benz E-Class. The contact stated while driving at an undisclosed speed, the contact noticed fuel odor in the interior and exterior of the vehicle.

2014 Mercedes e350 these models as well as those from2009-2015. Have recall on subframe but the brake lines rust out and deteriorate as mine has now done. If you go on line you tube etc. you will see the issue and all complaints. I had my subframe replaced under warranty at Mercedes of flemington. About 1 1/2 years ago. While it was being serviced they asked me if I wanted to replace brake lines for $1200 since they had this part out job would be easy. So this means Mercedes is well aware of the deterioration of these line the man at mb said the metal was inferior and this is result. On YouTube it was stated that individuals took mb to court or accountability for this but results were negative. Yet problem exists. If you breaks fail while driving it is very dangerous. Also I believe there is a recall for gas lines for my model 2014 manufactured from June and July. The brake lines on my vehicle are rusting as is gas tank. This also is dangerous condition should accidents occur the lines because compromised with rust can much easily rupture causing fuels to spew out causing possible explosive condition. I have pictures and can forward

Fuel smell in the rear of the car, it was checked by a indepent mechanic and the tank is leaking fuel. They said is the Fuel filter which is usually faulty in this model. It seems the car can catch fire according to the mechanig. No warnings of the leaking in the dashboard, only the strong smell.

The camshaft adjuster failure. Though I'm told safety is not in immediate danger, it's a very expensive fix that can cause other issues if left unpaired. It began subtly with strange noises, hesitation during start-up, inconsistent performance. I take meticulous care of this vehicle. Regular service. Genuine parts. Always handled with care. And yet, here I am, facing a repair bill that is not only shocking, but unjust. Especially for this to be a common problem. Not to mention the potential for severe engine damage if left unresolved. I’ve since learned that I am not alone. Many loyal Mercedes owners have faced the same issue; often at relatively low mileage, with little to no warning. This is not an isolated defect. It is a systemic issue with significant implications, not just for the vehicle, but for the trust your customers place in your brand. To say I’m disappointed is an understatement. I feel let down. Mercedes-Benz has always held a status. A great looking car. A great engineered car. And while this is a great looking car, it has a serious engineering flaw. German and Japanese engineered cars hold the standard and this must be fixed. A goodwill repair assistance, or a broader recall initiative would show some integrity.

Vehicle rear brake lines are corroded and leaking, while no corrosion was observed on surrounding parts

Odometer Fraud. The contact purchased a 2014 Mercedes-Benz E350. The contact discovered a mileage discrepancy after the purchase. The vehicle was a private sale. At the time of purchase, the mileage was 109,550. It was later discovered that the mileage on the Title was approximately 300,000.

While driving, the steering from left to right started to get choppy or hard. With the cruise control on, I ran off the road because of the fight between the rack and pinion(steering wheel) and the cruise control.

I've had the car for 3 years and its all stock. It has 38,500 miles and today out of no where the driver side speaker in the door started making a crackling and popping noise. Smoke started coming from the speaker and filled the cabin. I quickly pulled over and turned off the car, because the smell of plastic burning was horrible. I was immediately alarmed by this and let the car cool down. I started driving again and it started again crackling and alot of smoke coming from the speaker. I called my mechanic and he said that that car had a known problem for a short and others had complained about their speakers melting due to overheating from the amplifier. He quickly searched the fuse box numbers and had me pull fuse #67 that disarmed the amp and speakers but allowed me to drive the car again. There is no warning and this is extremely dangerous due to a possible car fire. I am just thankful that my wife or children were not driving this car when this happened. I researched the problem more and I can't believe there has not been a serious recall for those amps that came with the car.

Car unexpectedly swerves while driving!!

Rear brake lines have rusted out causing a safety concern. Mercedes will not extend the warranty to repair the recognized inferior parts as they did for the rear subframe. The rusty rear brake lines are related to the rusted subframe which was repaired under extended warranty by Mercedes at no cost. The same should apply to the rear brake lines. I am currently having the rear brake lines replaced due to this rust and safety issue. Please require Mercedes to extend the warranty and related repair to the rear brake lines as it is systemic to these cars.

While driving in stop and go traffic I heard a loud popping noise from the dash area and smoke started filling the cabin. I called a DC area dealer service dept and was told to exit the DC beltway and un plug the audio amplifier in the trunk left access door That stopped the popping noise and the smoke .

The emergency brake often gets stuck, especially on cold days. I have to repeatedly push and release it or manually adjust it by pushing behind the brake to return it to the release position. This problem starts on 28000 Mile on this car

Mileage 48,459 12/11/23 Rear brake lines replacement cost $4497. Repair not done at that time. Mileage 53,375. Again cautioned. 10/30/24 service date- Was informed that the rear subframe was corroded and would be replaced by Mercedes-Benz. I have photos from the dealer. There are holes in the rear subframe.The brake lines could be replaced at the same time at a cost of $2820 due to the fact it is in same area. Mileage 58,597 I asked M-B Customer Service to cover the rear brake lines as the under coating was not sufficient to protect the rear subframe and brake lines. They rejected my claim. I was told others have also tried to get M-B to cover this cost and were rejected. My vehicle has very few miles for its age. I have never had to replace rear brake lines in the 40 years I have owned a Mercedes Benz vehicle. I believe that they have not adequately protected the undercarriage from weather. The rear subframe is my evidence. At some point these brake lines could fail. They will be replaced. I want the manufacturer to cover the cost of the brake lines when the rear subframe is replaced. Please advise.

As I went to have my vehicle inspected, the mechanic advised me that it could not be inspected, that the car is totaled because the rear subframe is all rotted and the brackets holding the trailing arms were broke off and said that this was a common problem with these vehicles.
