Vehicle report
1998 BMW 540I
This model year
What the record shows
The 1998 Bmw 540i is a compact car, and the 10th model year of a nameplate NHTSA records from 1989 to 2025.
The EPA rated two configurations: a single 4.4-litre eight-cylinder engine, rear-wheel drive only, two transmissions and running on regular gasoline.
Combined fuel economy ranges from 16 to 18 mpg depending on which one you have.
The federal record holds 26 owner complaints and 18 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.
