“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. …”
