Owner complaints, recalls, fuel economy and safety ratings from public NHTSA and EPA data, updated Oct 17, 2026.
Fuel economy
39 mpgcombined; city 41, highway 37; every version of this model year; plug-in hybrid versions on gasoline, 117 MPGe on electricity
Five years of fuel
$10,500EPA's own estimate for plug-in hybrids: its national gasoline and electricity prices and the share of miles it expects on electricity; not priced for any state; every version of this model year; fuel only, 15,000 miles a year
NHTSA overall safety rating
Not ratedNHTSA has no overall rating for this year
NHTSA's VIN data lists no trims for the 2015 i3, so these are the versions EPA tested, by its names. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 47 complaints with NHTSA about the 2015 i3. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 3 recall campaigns for the 2015 i3 over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.

Unbelted, small adult, drivers may be at a higher risk of neck injury in the event of a frontal crash.
