The Warm Springs Extension suffered a series of delays from the original 2014 planned opening.
BART power cables unexpectedly needed replacement, and the new train control system on the extension proved difficult to integrate with the original train control system on the rest of BART.
By September 2016, BART planned to open the station the next month, which newspapers labeled an "October surprise" - a news event for the November 8 vote on a BART bond measure - but this did not occur.
The yet-to-open station was fully staffed beginning in September 2016 because BART union positions are only reassigned twice per year.

The station ultimately opened on March 25, 2017.
The conceptual design of the station was by local architect Robin Chiang, with final design by HNTB.
San Francisco Chronicle architecture critic John King praised the entrance rotunda with Catherine Widgery’s “Sky Cycles” artwork, but criticized the rotunda being scaled down from Chiang's design, as well as the lack of seating on the platform.
Seven bus bays south of the rotunda are used by AC Transit buses as well as private shuttles.

Because of delays with new BART railcars entering service, the station was initially served only by one line at a time (the Warm Springs/South Fremont–Daly City line on weekdays before 6 pm, and the Richmond-Warm Springs/South Fremont line at other times), with the other line running only to Fremont.
On September 10, 2018, both lines began running to Warm Springs/South Fremont for their full operating hours.

Some VTA bus service switched from Fremont to Warm Springs/South Fremont on October 8, 2018 as a result of the increased service.
Three of the four VTA routes serving Warm Springs were discontinued on December 28, 2019, during a reorganization of the VTA network.
The remaining route was discontinued upon the June 13, 2020 opening of the first phase of the Silicon Valley BART extension (after which Warm Springs/South Fremont station was no longer the southern terminal of East Bay BART service) leaving only AC Transit buses serving the station.
