For 2018 Ericsson retained his seat at Sauber, which became Alfa Romeo Sauber F1 team in partnership with the car outfit. Alongside he had a new teammate Charles Leclerc. At the Bahrain Grand Prix, Ericsson finished in ninth position, scoring his first points since the 2015 Italian Grand Prix, after a total of 49 races without scoring a point. He then scored further points at the Austrian, German, Belgian, USA and Mexican Grands Prix. At the Italian Grand Prix, Ericsson had a high speed accident in second practice at Turn 1, with a DRS issue causing the car to lose control and slam the wall where the runoff is. Ericsson hit the wall heavily, and flipped 3 times before coming to rest on all wheels but was uninjured.
