Does anybody know of the 2.0t ecoboost st engine failure? Was going down a dual carriageway and come to an island and the car just suddenly got a serious mis-fire. It turns out the pistons or Conrods have broke. Have been told by a st/Rs specialist the bottom half of the engine needs rebuilding because the engines aren’t that strong. Has anybody else had this problem? Had a quote for £3000 for a new engine or £4000 for a forged race engine. The car has just hit 40,000 mile and not been driven to its potential so am confused why this has happened. Anybody have any info on this. Cheers

Have you modified it at all? If so I've heard of it yes, the pistons are the weakest point. However it's not all that common really. You'll always hear about horror stories no matter what engine you find.

Having said that, those engines are crap compared to the bullet proof Volvo's fitted to the previous generation. Those engine's are good for at least 320hp on stock internals.
