Atletico Madrid lead 2-0 after the first leg at the Wanda Metropolitano.
The Serie A champions require a significant turnaround if they are to take their place in the quarter-finals.
Portugal international Ronaldo cut a dejected and frustrated figure throughout the 90 minutes.
Indeed his most significant contribution came after the game when he reminded the media of his five winners' medals in the competition.
No player has scored more goals in the history Europe's premier club competition but this term the 34-year-old has mustered just one in six appearances.
It is accepted that Juve acquired Ronaldo in an effort to end their 23-year wait for the continent's biggest club prize.
However, that investment looks like failing in its first campaign.
Juve have already outlaid £88m to sign Ronaldo from Real Madrid on a four-year deal.
During his maiden campaign at the Allianz Stadium the Italian giants will pay the five-time Ballon d'Or winner £26m, which the club must match in tax contributions.
Counting the cost of Cristiano
Transfer fee: £88million
Annual wages: £26m
Cost of failure to win Champions League: £40m
Should Max Allegri's side go all the way in the competition and win their third European Cup they can expect to recoup £110m in prize money.
The figure is also based on domestic rivals Roma, who lead 2-1 from the home leg with Porto, exiting the competition next month.
But if the Bianconeri fail to overturn the two-goal deficit in Turin against Diego Simeone's side, their winnings will only total £70m.
Though Juventus are likely to romp to an eighth straight Scudetto thanks to Ronaldo's 19 league goals, their dominance of Europe must seemingly wait another year.
