My guy @ denlo's didnt say anything about the other 3 however he did mention that they have had a few cases popping up with failed injectors. Also made reference to the talk online about these failures. So looks as though they are aware of the buzz on the forums about this.

Kinda freaked out it would happen again in the middle of the motorway or something... the way my carked it was so abrupt I reckon a major crash could have happened.
