Breaks became unusable due to lost power break fluid caused by corrosion on the lines. Fluid was completely gone and breaks were not effective at all. Dashboard showed RED light with break error. Dealer confirmed that rust build up caused the failure.

I have been issued a stop drive order under recall id# 22V315. I have contacted Mercedes Benz twice and been ignored twice. First call was around July 5th-2022 and second call was on July 12th. They apparently do not care about your stop drive notice as no one has gotten back to me on this issue.

"takata recall" my 2012 gl 450 Mercedes Benz ABS warning light came on while driving in the city. While driving at about 45 miles per hour the brakes engaged before I could stop my vehicle and pull over. It literally almost sent me through the windshield, a hard grinding sound and an intense stop. Still trying to get out of the way of traffic the vehicle jerked and jerked and the brakes continued to engage. This was very dangerous and could have caused a serious accident. This is very dangerous. If the ABS system is faulty or a bad sensor then it should not engage itself at all. I called the local Mercedes dealer and spoke with a specialist and he informed me that yes the brakes will engage if there is an issue with the ABS. Again this is very dangerous and a recall should be on the sensors whether it's the ABS sensors or the speed sensor which they also informed us that could cause this malfunction. Regardless the vehicle brakes should not engage while driving.
