Romain Grosjean felt Pedro de la Rosa was at fault in their collision in Q1 at Interlagos.
The Lotus was trying to slip inside the HRT on the run onto the pits straight when they clashed, squeezing Grosjean into the pit entry barrier and damaging his front wing.
De la Rosa continued with damage to his HRT, but was left last on the grid, while Grosjean could only manage 18th so was eliminated.
"I was behind Pedro for the whole lap," said Grosjean.
"I was going to overtake him in a straight line and I don't think he saw me and pushed me into the barriers. I braked as much as I could, but we had contact."
Grosjean had been fifth in final practice and was sure he was set to qualify well had the incident not occurred.
"It's a disaster," he said. "We had a very good car. I don't know what to say.
"Let's see tomorrow, the weather may be strange."
De la Rosa was adamant Grosjean was to blame, saying he could not understand what the Frenchman was doing.
