The west London side are currently just a point above the relegation zone and have lost six and drawn two of their last eight league matches.
Warnock, 63, took them back into the top flight last season but as recently as Friday the club's Malaysian owner, Tony Fernandes, warned: "It's important to note no-one's job is safe. Results are key."
On Saturday, QPR needed a last-minute goal to secure a 1-1 draw at Milton Keynes Dons in the FA Cup third round.
