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…

I provided an itemized repair invoice, proof of payment, and subframe rust/alignment failure documentation in my…

Last April, during our routine oil change our mechanic pointed out that our Cam sensors were wicking oil into the harness and making its way to the ECM. This is the first we had ever heard of this issue and the repair was $2400 or so. After researching the problem we wrote to MB USA and never got any response until we filed a lawsuit in sessions court. Turns out we cant do that locally. Mercedes has never contacted us since we registered the car in 2016 and never even acknowledged us until after we filed the attempt to collect the cost of repair. THE problem is endemic and well known. MB put a poorly designed part on their 270 engines and it could have had a worse outcome had the ECM failed…
