Webber will start from 10th on the grid for the Hungarian Grand Prix after suffering a KERS failure and a gearshift problem in the second part of qualifying.
Although Webber scraped into the top-10 shoot-out, his woes resulted in the team opting not to run him during the session, with cameras showing the 36-year-old storming out the back of the Red Bull garage.
An unhappy Webber said: "KERS, gearbox, you name it. Driving the car so far off the potential is unbelievable and massively frustrating.
"It's stupid, it's embarrassing and it's a brutal circuit to be out of position.
"We should be challenging for the front row and we're bloody 10th. So, a pain in the arse.
"It's amazing, all the effort you go to and it's two weekends on the bounce where you get that."
Three weeks ago in Germany it was Webber's car that lost a wheel during a pit stop and that hit a cameraman.
On home soil in the first race in Australia, the gremlins first struck the ECU that wrecked his start as he went backwards from second on the grid.
In China, Webber was demoted to the back of the grid due to a fuel irregularity discovered after qualifying, whilst during the race itself a wheel - for the first time this season - fell off.
Webber has implored the team to resolve his current problems, otherwise he knows he is going to face a long, hard, hot race, with temperatures forecast to hit 38 degrees centigrade.
"We're out of position with a car that is capable of much more," said
"The team have to get the car operating at the limit tomorrow. It's a long race and things need to be functioning correctly.
"KERS was 50 per cent (of the problem) and there were other things, so we managed to tick nearly every bloody box in qualifying, but we made it hard.
"Hopefully we'll get that sorted for tomorrow, but it's going to be hard to get the result we should do."
