Engine / equipment

Third-generation Hyundai i10, third-generation i20 and Bayon (petrol)

Period mentioned

2021–2023

Symptoms

Loss of power, hesitation or an engine that will not start for lack of fuel; it can leave the car stranded unexpectedly.

Possible cause described

The fuel pump may have a manufacturing defect. Hyundai recalled the i20 and Bayon built from 1/4/2021 to 3/12/2022 (campaign 51DT0, about 180,000 cars worldwide, German KBA alert of July 2025) and the i10 built from 1/11/2021 to 25/4/2023 (about 89,000 cars, March 2026). In both cases the pump is replaced.

Check for the garage

Check by VIN with Hyundai whether your car is in the recall and whether it has been done; replacing the pump takes less than an hour. If it is not in the campaign, the garage measures fuel pressure and flow before replacing parts.
