How strict are warranties when it comes to maintenance schedules?

[kschachn]

So asking for real experience with specifics....please share actual experiences when your warranty has been compromised or denied due to service record issues and why. I understand many may have heard "stories". I would really like to read actual factual accounts with the accompanying details, such as the vehicle brand, model, age and miles driven.

Thank you.

All right then here is mine. Never. Of course I do perform maintenance when necessary so perhaps that has something to do with it. But in my years of owning cars, many of them brand new, I have never had any issues with warranty whatsoever. In fact in a few instances the dealership has found things that I didn’t even know was a problem and they have fixed it under warranty. Most recently on my Tiguan it was a leaking oil pan gasket that was not visible from my perspective.
