Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
TRANSMISSION WILL GO INTO THREE BARS AND NOT SHIFT ON HIGHWAYS AND PARKWAYS, USUALLY ABLE TO SAFELY DRIVE UNDER POWER TO SIDE OF ROAD SOMETIMES GOES INTO NEUTRAL AND HAVE TO COAST TO SIDE. OCCURS WITH ELEVATED AMBIENT MOISTURE. STARTED AT 32,000 MILES. KNOWN ISSUE, TRANSMISSION HAS A LIMP MODE FOR THIS OCCURRENCE. VERY DIFFICULT TO DIAGNOSE, APPEARS ELECTRICAL IN NATURE. SMART DEALERSHIP WILL NOT ADDRESS.
I WAS DRIVING ON THE FREEWAY (5 LANE) IN MY 2012 SMART FORTWO PASSION COUPE IN THE MIDDLE LANE AT 65-70 MPH. ALL OF THE SUDDEN MY ACCELERATOR WAS NO LONGER FUNCTIONAL. I LOOKED DOWN AND SAW THAT MY SPEEDOMETER AND GEAR INDICATOR WERE ALSO NON-FUNCTIONAL. I WAS ABLE TO COAST (DESPITE HEAVY TRAFFIC) TO THE SHOULDER OF THE FAST LANE - IT WAS IMPOSSIBLE FOR ME TO GET TO THE SLOW LANE SHOULDER DUE TO HEAVY TRAFFIC. I WAS ABLE TO USE THE BREAKS ONCE I HIT THE SHOULDER (UNSURE IF POWER BRAKES OR NOT) AND ONCE STOPPED WAS UNABLE TO USE AUTOMATIC WINDOWS. I COULD NOT MOVE THE CAR OUT OF DRIVE FOR APPROXIMATELY TWO MINUTES. AFTER 2 MINUTES I TRIED AGAIN TO MOVE THE CAR OUT OF DRIVE AND WAS ABLE TO PUT IT IN PARK. AT THAT POINT I WAS ABLE TO RE-START THE CAR AND ACCELERATE ENOUGH TO GET BACK ON THE FREEWAY. I CONSIDER MYSELF VERY LUCKY TO HAVE BEEN ABLE TO REACH THE SHOULDER (AS IT ENDED ABOUT 200 YARDS DOWN THE FREEWAY). THE EXPERIENCE WAS ABSOLUTELY TERRIFYING. *TR

Seat belts
Reports naming seat belts, buckles, retractors and pretensioners.
From owner reports, verbatim
The driver side seat belt mount, which in this case is a steel cable, has mostly broken and frayed rendering it unsafe to drive. In the event of an accident, it would certainly break completely. I only noticed it yesterday while cleaning, the breakage would've happened while driving it. I've contacted mercedes USA, and they tell me that my warranty has run out, they can't do anything. Even though this is a mandatory safety feature that has completely failed from normal use.
DRIVER SIDE SEAT BELT FAILS TO BUCKLE. NOTHING LODGED IN BUCKLE, BUT MECHANISM APPEARS TO BE BROKEN.
