What these numbers are, before the table
These are complaints submitted to NHTSA by owners and drivers. They are reports, not confirmed defects and not a manufacturer finding, and they are not a failure rate: a car that sold well collects more of them than a rare one for no other reason than that more people own it.
The component category is chosen by the person filing, out of NHTSA's own list, which is why one of the largest categories on almost every vehicle is "unknown or other". Read the table as a map of what owners chose to report rather than as a ranking of what breaks.
All 30 categories.
Most reported first. Crashes, fires, injuries and deaths are counts of reports that also mentioned one, as recorded by the person filing.

What to do if your car is doing one of these
A category on this page is not a diagnosis. If your car is making a noise, showing a light, or leaking something, the useful question is what that symptom means and whether it needs the shop tonight or next week.
The symptoms guide works the other way round from this page: it starts with what you can hear, see or smell and says whether it is roadside, a tow, or a booking. If what you are seeing matches a recall campaign on this vehicle, the repair is free at a franchised dealer.
Who works on Highlanders in Brooklyn?
We do, at 619 Coney Island Avenue, Brooklyn, NY 11218, family owned since 1977. Diagnostics first, then the work, and a flatbed if it will not start where it sits.
NHTSA Office of Defects Investigation, owner-submitted complaints. Anyone may file one, they are published as filed, and NHTSA opens an investigation only when a pattern in them warrants it. A complaint that led to an investigation and a complaint that did not look identical in this table.
Registration counts: New York State DMV registration file, five New York City counties, August 17, 2026 snapshot. A registration is a record in a state database, not a car on the road, and the borough is where the registrant receives mail rather than where the car is driven. How we counted.
Fuel economy: EPA and DOE ratings published at FuelEconomy.gov, unaveraged, so each configuration is its own row. Recalls and complaints: NHTSA Office of Defects Investigation, the agency's own wording, as ingested August 17, 2026. Complaints are reports members of the public filed, not confirmed defects. The NYC registration study is the analysis these counts sit on top of.
