The rear brake line corroded and developed an actual brake-fluid leak. The failure triggered a brake-system warning and created a risk of reduced braking capability or loss of braking if the leak worsened. The problem was confirmed by an authorized Mercedes-Benz dealership, which diagnosed corrosion of the brake line and recommended replacement. The dealer provided a repair estimate and later reduced the repair cost through a goodwill review coordinated with Mercedes-Benz USA. This was not simply surface rust discovered during routine maintenance. The corrosion progressed to the point of an active hydraulic brake-fluid leak. The vehicle had approximately 79,349 miles at the time of the failure. Mercedes-Benz had also recently replaced the rear subframe on this vehicle under an extended warranty related to corrosion. Because the brake lines are located in the same general rear-underbody area, I am concerned that the corrosion may have been present or visible during that earlier repair. I am also aware that the federal safety agency previously reviewed rear brake-line corrosion involving 2010-2015 Mercedes-Benz E-Class vehicles under Defect Petition DP20-004. I am submitting this complaint because, in my case, the corrosion progressed beyond surface deterioration to an actual brake-fluid leak. This happened all of a sudden while my wife was driving to work and could have resulted in serious injury or death. The vehicle and failed components are available for inspection upon request, to the extent they remain available at the repair facility.

Brake failure by model year
What owners say
Was informed about the extended warranty for the rusting rear sub-frame issues on this make and year. Upon speaking with the dealership and further research online the rear hard brake lines are rusted as well and not covered by Mercedes. Upon further research this a common issue and danager to my safety and others as well. Upon work required to fix rear sub-frame would make it easier job to also replace rusted brakes lines. But Mercedes does not cover that and wants to charge customers a extra 3500$ to fix something that should not be happen as well. With the sub-frame out for replacement would make sense to replace other rusted parts with the extended warranty. It's a major safety issues already with rusted sub-frame and also added rusted brakes lines. This should be investigated further into to keep everyone safe. There are lot of owners unaware of this issues that could lead to brake failure. We use our brakes to stop and most new cars should not be having this issue so early.
Rear brake line failure, loss of brake fluid, caused loss of braking
The brake fluid lines rusted. The front line, due to the rusted hole, leaked brake fluid to the point that the car had little to no braking ability. In addition, the computer warning did not activate. The car was taken to the dealer, where they verified that the computer warning did not activate, and that the brake fluid had bleed out causing the vehicle to have no brakes. This is a dangerous situation! The car is a little over 10 years old, has about 54,000 miles. Had I been on the highway and tried to make a hard stop, I could have had a terrible accident. The dealer now has the car for repairs, but there are many other E350 that have posted online that they have had an identical situation where the brake fluid lines have rusted out! This leaves the driver, without any warning, to be put in a life threating situation!
Complete system brake failure. Brake lines are completely corroded.
