A "silent" recall is where a franchised dealer replaces some part or other when cars come in for a service. It is not a "general" recall where all cars are recalled.

If it didn't go in to a Vauxhall dealer after said recall was issued then, obviously, it wouldn't have been done.

If you were going to claim under a Vauxhall warranty you should have taken it to a Vauxhall dealer in the first place - involving any 3rd party only complicates matters.

A normal condition of a 3 year warranty is that services are done on time. If it wasn't then they are within their rights to refuse any payment. They might make a contribution as goodwill but if they stick firm and say no then I can't see what you can do. Was it overdue for mileage as well as time?

I think any recourse under SoGA 25 months after purchase when the car was overdue for a service is a non-starter.

"my car was 6 months old when I bought it (ex demonstrator model) as far as I was aware no warranty - however after reading up it appears there was warranty remaining for 2 years."

Are you real, what planet have you been on for the past few years. All new cars have a minimum 3 year warranty these days which is automatically tranferred to the new owner.

So by my basic maths your car was 6 months old therefore had 2 1/2 years remaining, provided it was serviced in accordance with Vauxhalls schedule, which it was not.

Was the service carried out by the independant done exactly to Vauxhalls requirements using genuime OEM quality parts and specified lubricants. If you cannot provide an invoice proving this your warranty would have been voided, its the rules that all makes have to abide by.

Sorry mate but you are stuffed.
