Vehicle report
2017 BMW 340I
This model year
What the record shows
The 2017 Bmw 340i is a compact car, and the 2nd model year of a nameplate NHTSA records from 2016 to 2024.
The EPA rated two configurations: a single 3-litre six-cylinder engine, rear-wheel drive only, two transmissions and running on premium gasoline.
Combined fuel economy ranges from 23 to 25 mpg depending on which one you have.
The federal record holds 5 owner complaints and 198 service bulletins for it.
Counts are reports, not rates. A complaint is something an owner chose to file; it is unverified and unadjusted for how many of these cars were sold, so the useful comparison is against other model years of the same car. Recalls and investigations carry more weight because a manufacturer or regulator acted on them.
Reading this report
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
