The BBC cast and crew abandoned their cars at the roadside after a crowd became enraged at a Porsche with the registration number H982 FKL.
Jeremy Clarkson, Richard Hammond and James May were escorted to the airport and left for Chile three days earlier than scheduled after protests led by Falklands veterans began outside their hotel.
A local paper covered the attacks, reporting that there were "people injured and police cars damaged".
The outrage first started when local Argentinian officials claimed that the Porsche's license plate was a deliberate reference to the 1982 war between Argentina and the UK over the Falkland Islands.
The BBC has confirmed that the Top Gear crew has left Argentina but declined to comment on the latest reports.
"Top Gear production purchased three cars for a forthcoming programme," he told the Guardian. "To suggest that this car was either chosen for its number plate, or that an alternative number plate was substituted for the original is completely untrue."
