i recently noticed some corrosion on the inside of the boot lid and the leading underedge of the bonnet.
Knowing that the car has a 12 year corrosion warranty, I submitted a claim via my local dealer but Mazda UK has rejected it, claiming it is outside the paint warranty. I don’t understand the difference - surely Mazda don’t expect me to wait until metal has rusted through as they will then have to fund a more complex and expensive repair /replacement of panels.

When you buy a new car from a Mazda Dealer, you get a comprehensive Manufacturer’s Warranty. It includes:
New Vehicle Warranty for 3 years or 60,000 miles whichever comes first
Paint and Surface Corrosion Warranty on body sheet metal panels against surface corrosion for 3 years regardless of mileage
Anti-Perforation Warranty on body sheet metal panels against perforation due to corrosion for 12 years regardless of mileage The benefit of transferring the Manufacturer’s Warranty to subsequent owners.
I am afraid I dont understand the difference between surface corrosion and perforation - surely they amount to the same thing, namely a hole where there shouldn’t be. I can’t believe Mazda expect me to wait until the surface corrosion has rusted though, leaving a hole where the designer didn’t put a hole.
Never experienced claiming for corrosion on any vehicle but pretty sure you would have had to have documented body inspection history from supply in order to make a claim and of course they will have to be perforated.
If it’s regarding the aluminium boot/bonnet then it won’t be rust, easily treated if only on the underside. I did my boot lid a few months ago, you can’t see the join so to speak and would be hard pushed to tell the DIY repair from that of a pro all for the price of a couple of rattle cans.
The warranty on my new Mazda3 back in 2016 specifically excludes any damage due to salt corrosion, etc. We have salted roads. Thus the perforation warranty is effectively useless.
The first thing I did with the car was to have it professionally fully under-sealed and wax injected with Dinitrol stuff while it was still clean and dry (65 miles on the clock.)
I have the same OPINION about perforation warranty in any car.
What with ex factory pre purchase storage/transporting incidents, stone chips when driving, salt roads, scratching due to cleaning (reasonable techniques included) etc I am not really convinced about paint warranties either.
All this after 30 years relevant disappointment with new car ownership (different manufacturers).
All I could say is that car paintwork is much much better than it was 2 to 3 decades ago.
The underside protection is somewhat better, but would benefit greatly from properly executed and expensive under sealing and wax injection if the car is to be kept to a ripe old age.
Right now my 2 year old MX5 ND needs storm damage repairs to the bonnet and I am concerned with reports that OEM paint may not be a 100% match or EVEN CLOSE!!
