| Electronic Stability Control problems |
Appears that my 2009 Smartfortwo 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.
At 45 mph, the abs light and the traction control light turn on. This deactivates both the abs and traction control systems making the car unsafe to drive at over 45 mph. A mechanic diagnosed the problem being crack in the abs sensor ring. Although a known issue, Mercedes Benz, the manufacturer of the Smart car, denies any issues with it. The repair that they performed was a replacement of the right axle shaft since they do not import a replacement sensor ring. This is a repair in excess of $700 for a $35 part. That part should not fail within such a relatively low mileage. Choosing not to repair could lead to a serious accident at speeds in excess of only 45 mph.
