He was then loaned to the Finnish SM-liiga to play with Jokerit in the 2011–12 season before returning to Sweden midway through the campaign to Skellefteå AIK.

In the 2013–14 season, Klingberg opted to play on loan with Frölunda HC, and produced a career high 11 goals and 28 points in 50 games. After post-season elimination, Klingberg was assigned to the Stars' American Hockey League (AHL) affiliate, the Texas Stars, and played in three regular season games.

In his first full North American season in 2014–15, Klingberg remained with Texas to begin the year. After being recalled by the Stars, he made his NHL debut in a 4–3 victory over the Arizona Coyotes on 11 November 2014. Klingberg scored his first NHL goal on 20 November 2014, against Mike Smith of the Arizona Coyotes. Klingberg finished first in points among all rookie defenceman in 2014–15 and was named to the NHL all-rookie team.

An unrestricted free agent at the end of the 2021–22 season, contract negotiations fell through with Dallas during the season after Klingberg and his agent turned down an 8 year contract with an average value of roughly $7 million, instead seeking out an annual cap hit of $8 million at 8 years. After failing to attract interest in a long-term deal during the opening weeks of free agency, Klingberg fired his agent and hired new representation; a lengthy contract never materialized and on 29 July 2022, Klingberg ultimately signed a one-year, $7 million contract with the Anaheim Ducks. In the 2022–23 season, Klingberg was leant upon heavily for the rebuilding Ducks, and struggled to match his career scoring pace however still led the Anaheim blueline with eight goals and 24 points in 50 games approaching the NHL trade deadline.

Leaving the Wild as a free agent, Klingberg joined his third club in short succession after he was signed to a one-year, $4.15 million contract by the Toronto Maple Leafs on 1 July 2023. Klingberg recorded 5 points in his first 6 games with the team, but then went scoreless in his next 9 with relatively poor play; on 23 November, the Maple Leafs placed Klingberg on long-term injured reserve due to hip injury. General Manager Brad Treliving revealed that Klingberg had been injured during an early team road trip to Florida in October, and had been playing through the injury for the past month. On 7 December, Treliving revealed that Klingberg was to undergo hip surgery at the end of the month and would not play again for the rest of the season.
