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.

SuspensionJul 2026 · ODI 11749054 · fireDetails +Close −
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."

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

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.

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.

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.

Dealer reports that, in addition to the dangerous corrosion on rear subframe covered by the extended warranty program, the rear brake lines are dangerously corroded and may fail at any time. I inquired about how this is even possible as I am accustomed to vehicles with cupronickel brake lines that do not corrode. I was told they are merely enameled steel on this model and prone to premature corrosion where they are mounted to the chassis with plastic clips that wear off the enamel and allow premature corrosion and eventually catastrophic failure. I was also told the replacement parts are now cupronickel, indicating Mercedes understands the original design was defective. I believe this should have been covered under the same program as the rear subframe, not be used as an upsell tool to customers affected by that issue. I also believe steel brake lines should just be banned outright for all vehicles, the risk of rupture due to corrosion leading to brake failure is far too high.

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.

Brake lines are rusted and corroded. It appears that the rust may have spread from rust on the rear subframe. The rear subframe warranty was extended for premature rust and failure, but the brake lines are not covered. This could have led to a dangerous situation. I've never had a vehicles brake lines rust like this. They should also extend the warranty coverage to cover rusted brake lines.
