On 23 June 2012, with Gustavsson soon to be eligible for free agency, the goaltender's rights were traded by the Maple Leafs to the Winnipeg Jets for a conditional seventh round pick in the 2013 NHL Entry Draft.
On 1 July 2012, however, after the Jets failed to sign Gustavsson, he signed a two-year, $3 million contract with the Detroit Red Wings instead.
His first victory came in a shootout victory over the San Jose Sharks on 28 February 2013.
He missed time due to injuries, however, ultimately appearing in seven games during the shortened 2013 NHL season.

Early in the 2013–14 season, Gustavsson was called upon to replace starter Jimmy Howard, who injured his left catching hand.
On 21 October 2013, Gustavsson was named NHL's First Star of the Week.
Gustavsson posted a 3–0–0 record with a 1.67 goals-against average and .953 save percentage in victories over the Boston Bruins, Columbus Blue Jackets and the Colorado Avalanche, helping the Red Wings move into first place in the Atlantic Division.

On 27 June 2014, the Red Wings signed Gustavsson to a one-year, $1.85 million contract extension.
He came off his best season in the NHL, with a 16–5–4 record, 2.63 goals-against average and a .907 save percentage.

On 5 November 2014, Gustavsson suffered a dislocated shoulder during the final seconds of an overtime loss to the New York Rangers.
On 31 January 2015, the Red Wings assigned Gustavsson to the Grand Rapids Griffins for a conditioning assignment.
During his conditioning stint, Gustavsson started two games for the Griffins, making 29 saves on 31 shots in a 4–0 loss to the Milwaukee Admirals on 31 January, and stopping 30-of-31 shots during a 3–1 win against the Toronto Marlies on 4 February.
