2003 INFINITI Q45
This model year
What the record shows
The 2003 Infiniti Q45 is a large car, and the 17th model year of a nameplate NHTSA records from 1987 to 2006.
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 12 owner complaints, 1 safety recall and 65 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.
