Transmission & Drivetrain complaints by model year
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.
NHTSA complaint #11758392 — an unverified report by a vehicle owner.
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.

NHTSA complaint #11520076 — an unverified report by a vehicle owner.
2008 Smart Fortwo has a recall open for reprograming the transmission computer because of rough shifting and bucking while shifting and lugging the engine to much before down shifting. Mine is a 2008 but the VIN was not included in the recall and I am having the same problems with mine. Can mine be added to the recall?
NHTSA complaint #11490643 — an unverified report by a vehicle owner.
DRIVER SEATBELT WILL NOT STAY IN TENSION RING. AT TIMES STUCK IN PARK & WHEN UNSTUCK WILL NOT ENGAGE ANY GEAR AND STOPPING AT RED LIGHT WHILE IN DRIVE SOON AFTER STARTING CAR IT WILL NOT MOVE WHEN ACCELERATOR IS ENGAGED. IN ALL CASES ENGINE MUST BE TURNED OFF THEN TURN TO POWER ON ONLY FOR 10 TO TWENTY MINUTES DURING WHICH EVENTUALLY CLICKING/CLUNKING SOUNDS ARE HEARD. AFTER HEARING THESE SOUNDS START AND SHIFT. REPEAT SOMETIMES TWICE BEFORE TRANSMISSION UNLOCKS. YOU MUST LEAVE ONE HOUR EARLY TO WORK OR APPOINTMENTS ANTICIPATING TRANSMISSION LOCKUP AND RESET PROCESS. USING THE YELLOW LEVER UNDER SHIFT CONSOLE WILL UNLOCK SHIFTER BUT WILL NOT AIDE WITH GEARS ENGAGING. USING GOOGLE SEARCH I FOUND OTHER OWNERS EXPERIENCE THE EXACT SAME PROBLEM.

NHTSA complaint #11131081 — an unverified report by a vehicle owner.
WMEEK31X09K[XXX] INTERMITTENTLY FAILS TO SHIFT INTO DRIVE OR REVERSE WHEN WHEN CAR IS STATIONARY. MOST OFTEN, THIS IS UPON STARTING THE CAR AND ATTEMPTING TO CHARGE NGE FROM P FOR THE FIRST TIME. AT TIMES THE TRANSMISSION INDICATOR SHOWS N WHEN THE GEAR SHIFT IS IN R OR D. OTHER TIMES IT IS BLANK. SHIFTING INTO PARK AND THEN BACK TO THE GEAR SOMETIMES RESOLVES THE ISSUE FOR THE TIME BEING. OTHER TIMES, TURNING THE CAR OFF AND THEN RESTARTING TEMPORARILY RESOLVES THE ISSUE. MOST RECENT OCCURRENCE TO DATE: MAY 17, 2018. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).'
NHTSA complaint #11096611 — an unverified report by a vehicle owner.
RANDOMLY, AFTER STARTING THE CAR AND SELECTING REVERSE, THE DASH DISPLAY DOESN'T DISPLAY 'R' OR IT FLASHES 'N', AND THE TRANSMISSION DOESN'T ENGAGE REVERSE GEAR. MOVING GEAR SHIFTER BETWEEN PARK AND DRIVE SEVERAL TIMES OR RESTARTING VEHICLE HELPS SOMETIMES. THIS WOULD BE VERY DANGEROUS IF NEEDING TO REVERSE IN AN EMERGENCY SITUATION AND THE CAR DOESN'T MOVE.
NHTSA complaint #11093459 — an unverified report by a vehicle owner.
I BOUGHT THE CAR AND LESS THAN TWO WEEKS THE TRANSMISSION WENT THERE WAS FLASHING AND BEEPING AND THE CAR WOULD NOT GO INTO GEAR. I BOUGHT A 2009 AND IN 2008 THERE WAS A RECALL ON THAT MODEL FOR THAT TRANSMISSION PROBLEM SOMETIMES THE CAR WON'T START SOMETIMES NOW AND THE HOOD LATCH IS BROKEN
NHTSA complaint #11078574 — an unverified report by a vehicle owner.
ON FIVE OCCASIONS, SUDDENLY AND WITHOUT WARNING, MY SMART CAR SHIFTED IN TO NEUTRAL BY ITSELF WHILE DRIVING ON THE HIGHWAY. WHILE THE SHIFTER WAS IN DRIVE, THE INDICATOR BELOW THE SPEEDOMETER WAS BLANK, AND THE CAR WOULD NOT MOVE. THIS PROBLEM ALWAYS SEEMS TO OCCUR AFTER DRIVING AT HIGHER SPEEDS. I TOOK THE CAR INTO THE DEALERSHIP AND THEY CLAIMED TO HAVE REPAIRED THE PROBLEM WITH A COMPUTER REPROGRAM. AFTER THE "REPAIR" THE CAR HAD THE SAME PROBLEM. THIS IS A VERY SERIOUS SAFETY ISSUE BECAUSE THE CAR WITHOUT WARNING COMPLETELY LOSES POWER AND ON MORE THAN ONE OCCASION I HAVE ALMOST BEEN REAR ENDED.
