2011 MERCURY MARINER
This model year
What the record shows
The 2011 Mercury Mariner is the 11th model year of a nameplate NHTSA records from 2001 to 2012.
NHTSA's best overall crash rating for this model year is 3 out of five stars.
The federal record holds 87 owner complaints, 3 safety recalls and 26 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.
