2008 Smart FortwoTransmission & drivetrainElectrical system

I was entering an intersection and missed judged the traffic light and was a bit to far forward, so I tried to reverse but the car would not shift to reverse. I have had an actuator replaced but the problem still happens intermittently where it will not shift to reverse. I have logged into smart car forums online and it seems to be an ongoing problem with many smart cars. I have not had the manufacturer look at it yet. Many on the forum said in some cases it is a software issue. But it is dangerous.

The Power Electronics Control Unit (ECM), Part No. A453-900-72-11, and the DC-to-DC converter have both failed, rendering this all-electric vehicle completely inoperable. There is no backup propulsion system. The DC-to-DC converter powers safety-critical systems including lighting, turn signals, and hazard flashers - its failure could cause loss of safety-critical functions while driving. Total repair estimate is $20,560.43. The manufacturer Mercedes-Benz USA denied warranty coverage using a Canadian warranty...

document for the wrong vehicle model. MBUSA has shut down the Smart warranty portal at the dealer level and their website returns no warranty data for Smart vehicles despite active warranty obligations. Smart exited the US market and MBUSA appears to have abandoned warranty support while warranties remain active.

The car won't charge over 20% due probably a faulty manufacturer part of N83 high voltage control box. This could cause very serious electrical/battery issues if the high voltage box is faulty.

2009 Smart FortwoElectrical systemDriver assistance

Appears that my 2009 smart fortwo passion and others on the internet are being confronted with many of the same exact problems. Vehicle will not go into r (reverse) at times and the keyfob may need to be reprogrammed for not working in the vehicle at all. Don't know if it is the electronic control module, transponder, or what. I do know that many owners are facing the same challenge. No need for a key remake, the keys just do not turn the car on at all. The programming equipment and or all that troubleshooting...

yet mercedes top executives have not and will not address owner concerns. I can pull into a parking lot, handle my business in lets say a supermarket. Come back out to the car and put in reverse and only n (neutral) appears. I have to go from neutral to drive then reverse for the vehicle to go into reverse. I bought this vehicle with 5 miles on it and have over 100k. One day on the way to work it shook bad. I pulled over. Had to be towed because the key would not turn the engine on at all. Gave it some time, the battery, windows, radio and dash light up, but the ignition absolutely nothing. Again, I have noticed on several sites many owners of the same vehicle are having the same issues. This is not an isolated electrical problem. The keys stopped working may 20, 2020. The reverse issue has been going on for years, do not have a time frame of when I first noticed it. Thanking you in advance for the opportunity to share my experience.*Dt consumer stated she would like to dismiss complaint.*Jb

2009 Smart FortwoElectrical systemLightsFuel system

Electrical fuses tend to cause electrical shorts, with a/c coming on and off at any given time, often when I hit speed bumps. The lights can be caused by this as well hitting the simple right corner turn can pop the light right out. I have repeatedly told them that it needs better shocks. I have replaced the lights both front and back at a very minimum of 12 times a year. That's ridiculous in my eyes.It should be smarter than that!!!!

I was on my way to school, the car began making a grinding noise, as I moved to the shoulder it died and the steering wheel locked up, the radio cut off, the horn stayed on, all the wipers went full force and the doors locked. When I finally kicked the door open I went to the front of the vehicle and opened the good. I began so smell burning plastic and went to the driver side again. When I got there, there were flaming drips coming from under the panels. I attempted to put them out but it was futile. I removed myself from the situation and called fire rescue. The whole thing took 2 minutes before the car was toast
