In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
Brembo aluminum calipers were used with steel bolts causing the breaks to get himot & seize the steel bolt in the calipers. 1 out of 2 brake jobs end up costing thousands & hours of work to get the seized bolts out, I have had a caliper fall off going 65 & got caught in between my tire & rear wheel arc.
-
Uneven tire wear in front, leading to repeated unsafe driving conditions unnoticed by driver because it is inside front tires. Nissan admitted problem, performed an alignment that did not remedy the problem and now will no longer return my calls. *jb
How to read this page
Every figure comes from the National Highway Traffic Safety Administration's public complaint database, which holds every safety-related defect complaint filed by owners since 1995. We refresh it monthly and count each complaint once per component it names. Data through September 6, 2026.
NHTSA only accepts safety-related complaints. Rattles, paint, infotainment bugs and other annoyances are under-reported here, so this page is a map of what fails in ways owners consider dangerous, not a full reliability score.
Counts are raw. Use the year-over-year shape and the component mix, not the absolute numbers. Where a component maps to parts we stock, the row links to that category filtered to the year you are viewing. Air bag and seat belt complaints link to the recall checker instead, because those repairs are almost always covered.
