2004 INFINITI M45
This model year
What the record shows
The 2004 Infiniti M45 is a compact car, and the 4th model year of a nameplate NHTSA records from 2001 to 2013.
The EPA rated one configuration: a single 4.5-litre eight-cylinder engine, rear-wheel drive only, a single transmission, Automatic (S5) and running on premium gasoline.
Combined fuel economy is 18 mpg.
The federal record holds 43 owner complaints, 1 safety recall, 1 investigation and 54 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.
