I am writing to formally submit a complaint regarding my 2010 E350 (VIN # [XXX] ). I have taken great pride in owning and maintaining this vehicle, and I want to share my concerns based on my recent experience. I have consistently kept this car well-maintained, following all recommended service schedules and ensuring that any necessary repairs were handled promptly. Up until now, I have not experienced any significant issues with the vehicle. It has been reliable, well cared for, and in excellent condition. Recently, when the brake line indicator came on, I immediately took the vehicle to a mechanic to have it inspected. I was informed that the brake fluid reservoir was empty and that there was a leak present. Upon further inspection, the mechanic identified that the leak was coming from the rear of the vehicle.

Car was found to have the rear subframe corrosion for issue. But also the brake lines were corroded very badly. They should be covered under the rear subframe extended warranty replacement. The rear brake lines are an frequent issue and almost always shows up when the subframe begins to rot. Also the pattern of the corrosion seems to be consistent across multiple incidents. Look at photos I uploaded and the Reddit post; identical. Look at this post from Reddit, almost identical corrosion on the rear brake lines as mine. Furthermore, it always is the rear brake lines, almost never the front. This is a manufacturer issue that needs to be looking into.

It seems like brake lines corroded and need to be replaced. Same issue in this car with subframe and that was taken care of by the extended warranty but brake lines were not part of extended warranty? That should be investigated further. Rear subframe rust out and brake line corrosion are obviously related but Mercedes is only addressing subframe. Why? A lot of people have this issue and it's a huge safety concern.

while driving once I start braking once the car is around 3mph it shifts from drive into Park and abruptly comes to a stop. Sometimes I am able to put it back into Drive sometimes I have to turn the car off and reinsert the key just to get it back into drive. Normally happens after an hour or so of driving the when I try to come to a complete stop the car will automatically shift into park. This is very dangerous as it can ruin the transmission also the person driving behind me can run into the back of my car. Is there any recall for this issue
