Filed with NHTSA by the people who own these cars, about the fuel system. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.

I bought this 2019 Highlander 2 months ago and the check engine light came on-the fuel injector was burnt up, replaced it, not even 24 hours later the car was pouring gas and check engine light back on..it barely has 30,000 miles on it. I will never buy a Toyota again.

Whether it is a problem on one particular car is a diagnosis, not a count, and a count says nothing about how many were sold.

Owners who gave an odometer reading reported it at a median of 10,000 miles; half of them between 4,000 and 15,000. That is when reports cluster, not the life of a part.

What does NHTSA's "Fuel/Propulsion System" heading cover?

Fuel tanks, lines, pumps and injection — and on an EV, the propulsion battery and motors. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
