Loses power accelerating on other Tucson 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, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
This group is about the moment you press the pedal and the car doesn't respond. Owners describe no acceleration when merging or climbing a hill, a sudden reduced-power or limp mode, and the check engine light coming on with it. A number say it happened more than once before anyone found a cause, and some mention a throttle body replacement.
What got replaced
Owners who name the part that was replaced mention the sensor (3 reports).
Recalls and investigations
2 recalls on the engine cover the 2017 model year. A recall on the same system isn't always the same failure, so read the defect text.
The connecting rod bearings inside the engine may wear prematurely, which can result in engine damage.
The affected vehicles may be equipped with an accessory trailer hitch wiring harness that, due to a malfunction of the tow hitch module, may result, in the trailer brake lights being constantly illuminated.

Should you keep driving it?
This page can't tell you that. 1 of 48 reports involved a crash and 1 people were hurt. 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.
