2011 INFINITI M56
This model year
What the record shows
The 2011 Infiniti M56 is a midsize car, and the 1st model year of a nameplate NHTSA records from 2011 to 2013.
The EPA rated one configuration: a single 5.6-litre eight-cylinder engine, rear-wheel drive only, a single transmission, Automatic (S7) and running on premium gasoline.
Combined fuel economy is 19 mpg.
NHTSA's best overall crash rating for this model year is 4 out of five stars.
The federal record holds 13 owner complaints, 2 safety recalls and 89 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.
