My wife leases vehicles and had a Honda CR-V on her last one. Part of the deal was free oil changes for the life of the lease. Dealer botched an oil change and it was leaking badly when she got home but no warning lights had lit up. I called them and, sounding like he was in a panic, the service manager said don't start it, we'll have a flatbed there shortly. Don't know if there was any long term damage as it went back a few months later but they were less than happy with some alleged mechanic, I'm sure.
