Route
No major changes are made to the route this year apart from some slight length-reductions to selected stages.
Normally, the road cleaner has to endure the insufficient grip, but this year in Argentina was different — persistent rain over the previous forty-eight hours meant the road was muddy and difficult to drive through for the crews who started down the road order. As a result, championship leader Thierry Neuville grabbed the lead as defending rally winner Ott Tänak lost valuable time with a broken drive shaft. The only casualty of the day was Esapekka Lappi, who was crashed out in the final stage of Friday and forced to retire from the rally. Coming to the second leg, the battle for the victory was extremely intense until Tänak stopped his Yaris due to an alternator failure in the afternoon loop. Another casualty of the leg was Elfyn Evans, who rolled his Fiesta heavily after smashed a huge rock. As a result, the Welshman was forced to retire from the weekend. Defending world champion Sébastien Ogier lost power steering in the morning loop, while Kris Meeke lost his brakes. Following the drivers ahead suffered issues, Andreas Mikkelsen charged himself to second overall after the oil-leak issue fixed. Eventually, the Hyundai duos managed to bring their team a 1-2 finish. Ogier completed the podium as Meeke receive a ten-second penalty for deviating from the correct route in Saturday morning's speed test.

Takamoto Katsuta was the first leader, but a puncture and broken wheel rim deposited his Fiesta into a ditch; Kajetan Kajetanowicz was the second leader, but he broke his rear suspension after landing heavily over a jump; Alberto Heller was the third leader, but he stopped in the penultimate test when his Fiesta's engine auxiliary belt broke. Eventually, the fourth leader Pedro Heller topped the category by almost six minutes after a day of attrition. Having a trouble-free Saturday, Pedro took the victory after overcame a big scare that the car stopped less than one kilometer from the finish of the iconic El Condórspecial stage.
