Brake warning light and other warnings from the electric vacuum pump on the Tucson 1.6 T-GDi

Engine / equipment

Hyundai Tucson (TL) 1.6 T-GDi (turbo petrol)

Period mentioned

2016–2017

Symptoms

Several warning lights come on at once on the instrument panel, including the brake warning light.

Possible cause described

The electric vacuum pump (under the engine) that assists the brake servo can fail at its cap and around its connector. Hyundai USA opened service campaign T3C (bulletin 18-01-026, September 2018) for 2016–2017 Tucson 1.6 Turbo: if warning lights are on, the pump cap is replaced; if not, the connector area is sealed.

Check for the garage

With the brake warning light on, check that the pedal brakes normally and go to the garage without delay: without assistance the pedal becomes hard. The garage reads the codes, removes the engine undertray and checks the electric vacuum pump, its cap and its connector.

Cost cited in the source

In the US, free under the service campaign; in Europe, ask Hyundai.A rough figure from the original database, not an up-to-date quote.
