When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

NHTSA investigations into the 2015 Smart Fortwo

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

Pedestrian alert sounds

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles.

Recalls on the 2015 Smart Fortwo

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2017143 5 units in Canada

Lights And Instruments

Certain vehicles may not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 108 - Lighting System and Retroreflective Devices. Vehicles may have been assembled with headlamps that allow for horizontal adjustment, which is contrary to the requirements of the standard. This could reduce vehicle visibility, or could adversely affect the vision of oncoming drivers during low light and night time conditions, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will install sealing caps on the headlamps to seal the adjustment screws.

Recall 2015135 1,278 units in Canada

Steering

On certain vehicles, bolts which connect the steering gear to the front cross member may break, which could affect vehicle handling and increase the risk of a crash resulting in injury and/or damage to property. Correction: Dealers will replace defective bolts.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.
