The contact owns a 2016 Smart ForTwo. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated with a loud whirring noise. The contact took the vehicle to an independent mechanic who diagnosed that the air intake changeover valves had failed. The independent mechanic advised the contact that the parts needed to fix the vehicle were difficult to locate. The vehicle was repaired. The contact stated that about a month later, the check engine warning light illuminated again. The contact took the vehicle to the same independent mechanic who diagnosed the vehicle with a secondary air injection pump failure. The independent mechanic advised the contact that the parts were difficult to find. The contact found the parts, and the vehicle was repaired. The check engine warning light illuminated again. The manufacturer was made aware of the failure and confirmed that the VIN was not included in a recall. The failure mileage was 58,299.

The car just shuts off while I am driving. I can tell now when it is about to shut off. I have had this problem since I purchased the car in 2016. I have taken the car to the dealership and called Mercedes Benz several times and they will not do anything. I will die because the car is getting worse and shuts off more frequently now. Can you get Mercedes Benz to help me? They told me that they don't care if I die due to a bad product they sold me. Please help. Please, I am begging you I do not want to hurt someone else due to this bad car.

MY 2016 SMART CAR AT ONLY 51000 MILES HAD TRANSMISSION FAILURE WHILE DRIVING DOWN FREEWAY ALMOST RESULTING IN CRASH. MY CAR WENT FROM 65 MILES A HOUR, THEN WARNING LIGHT SAID TRANSMISSION FAILURE AND CAR WAS UNABLE TO EXCEL RATE OR BREAK, THE EMERGENCY BREAK WAS THE ONLY THING THAT SAVED ME. MERCEDES DIAGNOSED A WIG WAS ABLE TO FLY UP UNDER CAR AND GET WRAPPED AROUND AXELS, TRANSMISSION, AND BREAK BELTS. THE CAR WAS TOTALED FROM A WIG. THIS IS UNACCEPTABLE THAT THE UNDERNEATH IS LEFT VULNERABLE TO A OBJECT BEING ABLE TO CAUSE SO MUCH DAMAGE, THAT COULD HAVE EASILY RESULTED IN A FATAL CAR CRASH. THIS HAPPENED ON HWY 59 SOUTH HOUSTON, WHILE DRIVING.

17V448000 · Parking Brake

Jul 16, 2017

Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2016 smart fortwo vehicles. In these vehicles, the lock nut that secures the parking brake cable to the parking brake lever may loosen over time, resulting in increased parking brake lever travel before the parking brake engages.

Consequence & remedy

Consequence: As the parking brake lever travel increases, the holding force may decrease to a point where the vehicle is no longer safely secured in all parking situations, allowing the vehicle to unexpectedly move when parked on a slope, increasing the risk of a crash.

Remedy: MBUSA will notify owners, and dealers will replace the parking brake cable lock nut, free of charge. The recall began September 20, 2017. Owners may contact smart customer service at 1-877-496-3691.
