I purchased my Fiesta S brand new from a dealership in 2015. The car was regularly serviced with my mechanic as per the vehicle logbook.
About 6 weeks ago the engine cut out after making a rattling sound and wouldn't start again.
It was towed to my mechanic who diagnosed it as a broken timing belt. Even though it was out of warranty, the timing belt was not due to be changed until 150,000km - my vehicle had travelled 105,000km. I got in touch with Ford head office who got me to have the car towed to the local dealership (where I purchased the vehicle).
The dealership diagnosed the issue as the teeth that drive the timing belt have worn away due to "incorrect oil or oil not being changed". The car needs a new engine. They got me to submit my receipts from the mechanic to them so they could see that it was serviced correctly with the correct oil.
My mechanic is old school (our family has been going to him for years), and hand writes receipts in an invoice book.
The dealership have come back to me and are vaguely accusing me of forging receipts ("anybody could have written them"), they want nice typed receipts from accounting software, and the response from Ford corporate is for them to pay 25% of the new engine cost, and me 75% - my out of pocket expenses would be around $6500.
I'm not accepting this outcome as I have receipts to prove the oil used was correct and was changed as per the servicing schedule, just because they're hand written from my mechanic shouldn't have any bearing on the outcome - written receipts from an invoice book are still legal and valid receipts. My mechanic still has the duplicate copy in his invoice books.
I don't know where to go from here as I feel I am being given a raw deal due to handwritten receipts!
TLDR: Timing belt broke 45,000km before it should have, dealership saying it's because "wrong oil or oil not changed". Oil was correct and was changed. Dealership don't like the mechanic's handwritten receipts and are now saying I am liable for 75% of the cost of a new engine.
Edit: My case manager at Ford has been very helpful and understanding, I just feel like the dealership (who have been terrible!) is giving Ford incorrect information and is hindering my chance at a fair response.
