The Spanish driver rolled his Citroen DS3 WRC on the second stage of Thursday morning, dropping almost seven and a half minutes.
Sordo had already rolled Citroen's demonstration DS3 WRC at a promotional event in Buenos Aires last weekend.
His co-driver Carlos del Barrio had been distracted by a half-open door on the Ascochinga stage. He tried to close it properly in a fast section before a hairpin, then miscalled a pace note shortly afterwards.
Sordo said he was not angry at del Barrio over the error.
"Carlos told me the wrong note. He told me it was a flat corner, but that was not this corner," Sordo told AUTOSPORT.
"The car went over and stopped on its roof.
"Sometimes I make a mistake, sometimes a co-driver can make a mistake - everybody is human. It's early in the rally, what can I do?"
Sordo is running 15th after the crash, losing much of the time with broken power steering as a result of the roll.
