Power train

39 reports3 crashes1 fire
“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.”

Engine

34 reports16 fires
“Mercedes-Benz USA has no service centers on Long Island,NY that might fix the recall issue. For a time they were the only Smart Car service provider after Smart Car dealers were abandoned. MB USA currently will not do the recall and offers no reasonable alternative. The issue is potential engine compartment/total vehicle fire due to compartment insulation failure. Offers no suggestions for doing the recall service except one MB dealer in CT at one time might be able; if I research them.”

Seat belts

10 reports
“THE SEAT BELTS WILL NOT RETRACT, WHICH SHOWS THEY DO NOT WORK PROPERLY. CONCERNED THEY WILL FAIL IF I'M EVER IN A CRASH. :( THIS HAPPENS EVERY TIME A SEAT BELT IS UNFASTENED. THE ISSUE HAS BEEN HAPPENING FOR A FEW YEARS. CALLED A LOCAL MECHANIC TO ASK IF THEY COULD FIX IT, BUT APPARENTLY THIS IS CONSIDERED A SAFETY ISSUE, SO THEY WON'T TOUCH IT. SMART DOESN'T ADMIT IT'S AN ISSUE EVEN THOUGH MANY OTHER SMART OWNERS HAVE COMPLAINED OF THE SAME ISSUE. PLEASE ISSUE A RECALL SO WE DON'T HAVE TO WORRY ABOUT OUR SAFETY AS FAR AS THE SEAT BELTS ARE CONCERNED.”
