The station opened on September 13, 2015, at 1:00 p.m., in a ribbon-cutting ceremony attended by New York City mayor Bill de Blasio, U.S. Senator Chuck Schumer, and former deputy mayor Dan Doctoroff.
The secondary station entrance at 35th Street, as well as finishing touches within the station itself, was not expected to be completed until 2016.

However, a couple of days after the station opened, there were some problems in and around the station, which multiple news outlets criticized.
An escalator broke down on September 14, just a day after the station's opening.
In an unrelated September 16 incident, a straphanger got injured while walking up another escalator at the 34th Street station.
Earlier that day, the New York Post reported on signal problems in the brand-new tunnels around the station, while riders complained about the delays on Twitter and Reddit.
A Wall Street Journal commentator remarked that "it's only a matter of months (make that weeks) before the gleaming station ... is pockmarked with chewing-gum spots, urban scrawl and litter."
Overall, however, the station was received positively during its first few days of service.
In an article in several newspapers distributed by NYC Community Media, Lenore Skenazy writes that many riders have praised the station's design, its cleanliness, and its climate-controlled platforms, and noted herself that the station looked and felt "as uplifting as a cathedral".

In March 2016, news sources reported that despite the station's high cost, the station had maintenance problems: there were leaks in the ceiling of the corridors holding the escalators, the station's bathrooms were closed because of flooding from the street, and icicles had formed on the ceiling of the station.
The MTA supposedly knew about the issues for several years, even during construction.
The MTA board called these issues "unacceptable" and the contractor responsible for waterproofing the station spent $3 million to fix them.
The leaky ceiling was reportedly fixed by May 2016.
At least one passenger filed a lawsuit against the MTA because of injuries sustained after falling down an escalator to avoid the leaky ceiling.

In 2017, part of the mezzanine was closed off so the MTA could build a mockup of the proposed R211 subway car.
The model was open to the public from November 30 to December 6, 2017.
The mockup contained features such as an open-gangway design proposed for this order; digital screens showing next stops and their station layouts; and a blue-and-gold-stripe paint design on its exterior.

A secondary station entrance at the southwest corner of 35th Street and Hudson Boulevard opened on September 1, 2018, nearly three years after the station's opening.
The secondary entrance provides access to the north end of the station.
In March 2019, the MTA reported that the 34th Street–Hudson Yards station contained three of the ten least reliable subway escalators in Manhattan.
Each of the escalators was out of service more than one-sixth of the time.
One of these escalators, at the 35th Street entrance, was closed 25 times from October to December 2018.
