Thanks for asking! Iíve never had a warranty that I regretted. While my ML has a mere 13.5K miles in a little over a year, I hope to have and enjoy it until it has well over 100K miles. Having talked with the mechanics at my local dealership, Iím well aware of a number of so called pattern failures down the road. In short, replacing components is the only way to fight components with a relatively short service life.
