Paul di Resta insists his Marina Bay DNF was not a driver error but rather a problem with his VJM06.
The Force India driver suffered his fourth retirement in as many races when he crashed out of the Singapore Grand Prix on Sunday night.
Fighting for a top-ten result, di Resta appeared to make a mistake with seven to go that sent him into the barriers at Turn Seven.
The Scot, though, is adamant he did nothing wrong.
"For whatever reason something went wrong," he told Press Association Sport.
"I did nothing different, but the car didn't stop, it locked the outside front wheel.
"So there is a big question mark over what exactly went wrong. It would appear to be something mechanical.
"If it is something I've done wrong then I'll stick my hand up and take the blame for it, but it doesn't look like I've done anything wrong at the moment.
"The team are looking into it."
