I have a ford cmax with an ecotec engine, and took out an extended warranty
Leaky drive shaft seal was noted on the last service. Repair cost about £400 (dealership prices). The part itself is cheap but it involves taking half the engine apart.
They then said it wasn’t covered under warranty. I checked and it does explicitly say that seals and rubber parts are not covered in the small print, which made me feel like a right numpty for paying for a worthless warranty.
I complained, called, emailed, many times, and it took months actually for them to resolve. They dealt with it so poorly that was worse than the actual original issue with the car! Eventually they agreed to cover the cost.
My arguament was that the warranty was mis-sold. At no point did they explain the potential high repair costs for the things that the warranty excludes. You assume (and this is how it was sold to me by the dickhead salesman) that all expensive repair bills will be covered – obviously not brakes, tyres etc.
Hope you get it sorted. If they try telling you it’s not covered by the warranty then it’s well worth making a fuss about it.
