It's been a nightmare for the Woking based McLaren Formular One team so far this season.
The expectations for this season where high after McLaren went from a Mercedes engine back to the familiar Honda engine.
McLaren raced with Honda engines from '88 to '93, winning a championship with Ayrton Senna in their first season equipped with Honda. McLaren returned to Honda in 2015 after 19 years with Mercedes engines.

But this season it's been nothing like they had hoped for. The team that has won 182 races through history has only 17 points to their named over half-way in this season.
There has been engine failier after failier and that's not the end. In those rare occasions that the egine works, it lacks power like nothing else. Honda says that they have around 25 more horsepower than the Renault engines - engines that Red Bull and Toro Rosse use - but during the Italian Grand Prix the Renault powered cars just drove past McLaren like it was overtaking on the M1.
Now McLaren has had enough. The relationship appears to have reached a breaking point amid reports which say that McLaren has asked for Yasuhisa Arai to be removed from his position as chief motorsport officer.
According to The Daily Mail:
'McLaren are so exasperated at Honda's woeful performance that they have written to the company's president, Takahiro Hachigo, calling on him to replace Arai'.
According to Sky Sports sources the claim from The Daily Mail is true and the McLaren CEO has written to Honda, although the exact contents of the dispatch are unknown.
Fernando Alonso told reporters that the MP4-30 was losing around 0.3 seconds to the Mercedes in corners, with the rest of the deficit due to the deficiencies of Honda's underpowered unit.
"They're 11km/h slower down the straights here. If you get run into at 11km/h, you'd break your leg wouldn't you!?" noted Sky F1's Martin Brundle.
"Even if it blows itself to smithereens every day, but showed signs of going a lot faster, that would be fine. You can fix the reliability to an extent. They just lack pace; they lack power."
With McLaren facing their worst contructers finish ever the prize-money revenue loss could have a massive impact on the teams future.
It looks like Honda will have to get back to the drawingboard if this love story isn't ending like a horror story.
