The brake fluid lines are corroding much faster than in other models, and without actual corrosion under the car. It happened to my car, and I have been reading forums of MB owners of this same R model, as well as C, E, GLK, and ML models all reporting the same issues. The lines corroding earlier to due to the brake boost system failure and other fluids/air entering the system is the most consistent cause of brake line failure I was able to get off the internet, as well as MB not using lines with proper material. The only thing I know is that the lines are not supposed to fail this early and this bad.

Hi I received a letter from Mercedes for a stop drive recall (NHTSA #22V315, MBUSA ID: 2022050014 & 2022050015), so I bought my Mercedes R350 to the shop for repair on July 15, 2022. Mercedes Benz of Pleasanton (925463-2525) claimed that brake booster parts were not available at that time and I couldn't drive the car, so they …

Hi I received a letter from Mercedes for a stop drive recall (NHTSA #22V315, MBUSA ID: 2022050014 & 2022050015), so I bought my Mercedes R350 to the shop for repair on July 15, 2022. Mercedes Benz of Pleasanton (925463-2525) claimed that brake booster parts were not available at that time and I couldn't drive the car, so they left the car at the shop waiting for the parts to become available. Later on when I called, the service rep claimed the parts had been ordered so kept my car in their lot (since July 15, 2022) Since then, I have been on the rental car (that I am still paying for) and I reached out to them multiple times and couldn't get a status update from them, nor schedule for my car return. I Hope NHTSA can help me to receive an update of my recalled vehicle, and their solution. I don't know how long do I need to use rental car. I would like to file an official complaint to Mercedes Benz USA. They don't seem to know how to handle their own recall. Thank you in advance.

I have tried, since 730 this morning to find out what can be done with regard to the recall of my car. I contacted my dealer - Faulkner Mercedes in Doylestown.... who explained that they couldn't do anything, as they have neither the tools nor the parts to address this issue, and won't have for quite some time, and that I needed to call the Mercedes recall hotline. Which, I did. While on hold for about 40 minutes to get through to someone, they took my information and told me that there was nothing that could be done, because the "Recall hadn't been launched yet" and that it would be a few weeks before I'd get a letter in the mail telling me what I needed to do. This is absurd. First off, most people will give up and not wait on hold and keep driving, and second, I need my car, as do the other 292,000 drivers - and these people can't wait weeks to get a letter. Most will have no alternative but to drive them while waiting for Mercedes to address this problem. Mercedes needs to provide loaner cars, and needs to do so, immediately.
