I only have 400 miles left on my warranty. I don't have door cracks ('99 Lariat), but I can almost see it getting ready to crack after the warranty is up. Just a slight bulge right now.
Soon, when the warranty expires, and my door cracks, I'll be almost relieved it's over. It pains me to have one eye on the bulges and one eye on the odemeter. Dangerous too.
