What is the failure rate for Ford EcoBoost wet belts?
I have a Ford Fiesta 125 EcoBoost which I have had from new, and has just short of 30k miles on it now. It has been serviced exactly in line with Fords schedule by a franchised main dealer, so assume all correct parts and fluids have been used. The car is in mint condition so I am reluctant to sell it, but I am fast approaching the time when I need to decide the way forward.
I assume there is no way the condition of the belt can be checked, so do I keep to the schedule with fingers crossed or bite the bullet and change the belt early. Do you have any info on the failure rate?
It is a pity that Fords engineers spoilt the design of such a brilliant little car by making such a vital engine part so difficult and expensive to service, and one that would effectively write the car off if neglected and it fails.

The majority of issues reported with wet belts in EcoBoost engines have been with oil contamination and degrading of the belt over time, so the fact that you have followed the service schedule minimises the risk of a failure. Ultimately it comes down to how keen you are to keep the car - if you are planning to hold on to it for several more years, changing the belt early would make sense and give peace of mind for the future. We do not have access to data around failure rates, but the fact that it is a topic of discussion among owners would suggest it is more common than a typical failure rate.
