The LCR Honda rider was trying to pass Quartararo for 10th on the opening lap of Sunday’s rain-hit grand prix at Rio Hondo when he went in hot and made contact with the Yamaha.
Quartararo was forced into the blue painted run-off area and plummeted to 16th in the depleted 17-rider field and was forced into a recovery ride.
The incident was placed under investigation by the FIM stewards, but they deemed no further action was necessary.
Quartararo – who labelled Nakagami a “kamikaze” on French television afterwards – was unhappy with the stewards’ decision.
“No, I don’t understand what they are doing,” Quartararo said on Sunday in Argentina after the clash.
“I watched the Moto3 race: Ayumu [Sasaki] in Turn 5 make an overtake that was really clean, but he slightly touched [another rider and got a penalty], where in MotoGP we are doing it all the time.
“He [Sasaki] got dropped one position and he [Taka] just destroyed my race in one corner and didn’t get anything.”

Nakagami has defended himself for the clash, saying he did nothing over the line – though concedes he was “overshooting” the corner when he went for the overtake.
“Well, looks like from the outside it was a little bit aggressive,” Nakagami, who was 13th in the grand prix, said.
“But honestly that moment I thought I could overtake, but was slightly overshooting and missing the apex.
“But it wasn’t crazy, it’s not like crazy riding. We touched a little bit each other, but this is racing.
“I have nothing to say. I didn’t make any mistake. Luckily, he didn’t also crash. Of course, he lost the position, I want to apologise. But this is racing.”
This is the second lap-one collision in the space of a year triggered by Nakagami that has gone unpunished, much to his rivals’ annoyance, after a Turn 1 pile-up involving Alex Rins and Francesco Bagnaia in Barcelona last season was deemed a racing incident.
Quartararo was able to recover to seventh after the Nakagami clash.
