First day leasing the vehicle within 6 hours lights malfunction and malfunction warning on dash to seek workshop, vehicle was taken for inspection to original dealer (Mercedes Benz of Bakersfield). During inspection I added additional concerning complaints about passenger door not closing correctly/wind noise seeping through when closed, and hood not closing promptly. One month into leasing vehicle passenger window malfunction, took for inspection and repair to original dealer (MBofBakersfield). Concerned with caution for me, my family, and friends when in that vehicle for giving faulty signs so early. One year into leasing vehicle check coolant warning on dash, took for inspection to original dealer. I am now more concerned as it went form electrical to coolant components losing coolant with no reasoning from original dealer service other then a top off. Vehicle drive is rough. 1 year and 6 months into leasing vehicle, again check coolant warning on dash. Took in for inspection, gave no reasoning from original dealer service dept, other then a top off done. Vehicle drives rough. While driving 70mph, a vehicle behind was approaching quick when I went to excel to merge vehicle seemed to be slipping in gear/slow down. No warning lamps on, Quickly decided/managed to merged to next lane so vehicle behind didn’t hit us as we were slowing down With 2 children in the back seat. decided to exit to nearest exit to pull off as it felt unsafe to drive, as exiting and slowing down vehicle began to shake, knock, and make loud bangs. Managed to pull over, and check dash for messages for any type of warnings. No warning lamps, but many symptoms of a faulty unsafe vehicle. Had vehicle towed to original dealer service for diagnosis and report the unsafety incident that occurred with absolutely no warning lamps. Inspection lead to repair of engine but nothing done about no warning lamps/electrical system
