In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
Takata recall for front suspension transverse link. I think this vehicle belongs in the list and of the i30t 2001 infiniti and so does the mechanic that inspected the vehicle
-
Consumer infiniti check engine light illuminated mechanic determined there was excessive high voltage. *ts the coils were defective which were affecting the ignition- signal which was causing the high voltage.*jb

The brake cable assembly is made with an inferior bracket that causes the cable to rub against the suspension wearing through the cable. Eventually it would cause the cable to be cut through. Photos are available.
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.
