Composite volcanoes. Some of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes. They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases.
Sample Coverage. If the Chevrolet manufacturer's factory warranty is still in effect, anyone who owns the vehicle during the warranty period is entitled to warranty service. The warranty covers any repairs needed to correct defects in materials or workmanship of all covered parts and components.
Batteries and Tires are rarely covered under the manufacturer warranty. I worked in the business for many years on the service and fixed operations side, including with Ford (Canada). They have their own warranties provided by the manufacturer. I would go with the dealer on this one.
