Common problems with the 2015 Fortwo

NHTSA's file holds 11 owner complaints on the 2015 smart Fortwo. Owners named the engine most often: 2 complaints. A complaint can name more than one component.

Mileage when owners reported a problem with the 2015 Fortwo

Too few complaints on the 2015 Fortwo list a mileage to say when owners reported problems: 8 of its 11 complaints list a mileage (1,600 to 65,000 miles), and a median is given here only with 10 or more.

These mileages say when owners reported a problem, not when a 2015 Fortwo wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.

Every model year together: Half of the 309 NHTSA owner complaints on the Smart Fortwo that list mileage came after 29,000 miles (NHTSA complaints file of November 11, 2026). How many miles will a Smart Fortwo last? →

Is the 2015 Fortwo a good year?

Complaint counts cannot say whether the 2015 is a good or a bad Fortwo: they rise with how many were sold and how long they have been on the road. They show how the 2015 compares with the other model years in NHTSA's file.

With 11 complaints, the 2015 drew the fewest of the 7 smart Fortwo model years from 2008 to 2016 with 10 or more complaints. The most: the 2008 (177).

Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.

What these figures can and cannot tell you

  • Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
  • The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
  • The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
  • They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2015 Fortwo lasts.
  • A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2015 Fortwo.
  • Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
  • 3 of the 11 complaints on the 2015 smart Fortwo give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
  • NHTSA names counted: FORTWO, FORTWO CABRIO, FORTWO COUPE, FORTWO COUPE ELECTRIC and FORTWO CABRIOLET. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only these.
  • Recall-file names matched: FORTWO, FORTWO CONVERTIBLE, FORTWO COUPE and FORTWO COUPE ELECTRIC.
