Lewis Hamilton hit out at his Formula One team Mercedes after he was forced to retire from 2016 Malaysian Grand Prix due to engine fire on Sunday.
The Brit made a good start from his pole position and was leading comfortably for most part of the 56-lap race in Sepang. However, his Mercedes engine blew up during the 43rd lap forcing him to get out of his car.
Red Bull's Daniel Ricciardo, who was trailing behind, capitalised on Hamilton's engine failure and went on to win his first title since the 2014 Belgian Grand Prix.
Sunday's mishap meant Hamilton (265) fell 23 points behind Mercedes teammate Nico Rosberg, who finished third at Sepang, in the championship title race.
A distraught Hamilton, who was robbed of a seventh title of the ongoing season, demanded an explanation for repeated engine troubles from Mercedes. Notably, he has already served a grid penalty for using maximum power units in 2016.
With only five more races to go in this season, the defending champion lamented falling behind Rosberg in the championship battle and said he does not know what his engines have got in store for him.
"I just can't believe that there is eight Mercedes cars, and only my engines are the ones that have been going this year. Something just does not feel right, but there is nothing I can do about it," Hamilton was quoted as saying by the Formula One official website.
"I know that we have it within us, my engineers and my mechanics, I know we have got it in us - but who knows what the engines are going to do.
"I am just going to keep my head down and hope for the best - but obviously today was not a good day."
Mercedes, however, maintained they received no prior signals about the engine failure. The German team's non-executive chairman Niki Lauda conceded he felt sorry for Hamilton and that they were not against the 31-year-old driver.
"I am really upset about myself and my organisation because we should not let him down with an engine failure," Lauda said, as quoted by the Sky Sports.
"I can convince him that we have nothing against him. We are working for him and are proud of him, but these things can happen."
Meanwhile, Max Verstappen sealed the second spot to ensure Red Bull finished one-two and extended their lead to 46 points over Ferrari, who are third with 313 points in the 2016 constructor standings.
Ferrari's Kimi Raikkonen finished fourth after his teammate Sebastian Vettel collided with Rosberg at the first corner before retiring. The Mercedes driver, despite dropping to the last spot, recovered well and raced to third position.
The championship leader even survived a 10-second penalty after making a bold move against Raikkonen in the 38th lap of the eventful race.
