Webber said in the press release that his fuel flap becoming stuck open at Sakhir was "bloody frustrating", before his RB3 single seater's gearbox broke.
The release also quoted him as saying: "The pace was good, but the result is the same even so."
In the raw, however, 30-year-old Webber did not mince words, explaining that the faulty fuel flap is a recurring problem at the Milton-Keynes based team so far this year.
"It's frustrating to say the least, and it's not good enough," he angrily told reporters in the paddock, insisting that the Adrian Newey-penned car breaks down "too often".
Teammate David Coulthard's Red Bull also failed with a fiery driveshaft problem, having impressively overtaken more than ten cars after starting from the back.
Team boss Christian Horner said: "We need to get on top of these reliability issues very quickly, as obviously they're unacceptable."
