Misfire on other Highlander years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2015, 2016, 2018, 2020, 2021, 2022, 2023, 2024.
What this problem usually is
These reports start with the check engine light. Many describe the engine running rough or shaking at idle, a P0300-series code, or a catalytic converter code. A worrying number say the light was flashing. Owners often list ignition coils or spark plugs already replaced, and the light coming back afterward.
What got replaced
Owners who name the part that was replaced mention the sensor (3 reports).
Recalls and investigations
2 recalls on the fuel and propulsion cover the 2019 model year. A recall on the same system isn't always the same failure, so read the defect text.
The low-pressure fuel pump inside the fuel tank may fail.

Should you keep driving it?
This page can't tell you that. 0 of 41 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
