Many types of auto warranties provide coverage for windshields, including comprehensive car warranties and bumper-to-bumper warranties. However, these warranties may be voided if the windshield cracks or breaks due to certain conditions, such as negligent driving. Generally, parts that are not covered by a new vehicle's bumper-to-bumper warranty are those that deteriorate from constant use, such as windshield wipers, tires, brake pads, brake rotors, light bulbs, and window panes. Depending on the brand of the vehicle, some of these parts may be covered for a shorter period.
For instance, State Farm offers free replacement of windshields if you have comprehensive coverage with them. Honda will also replace a broken or chipped windshield if the damage was due to defects in materials or poor workmanship. In some states (Arizona, Florida, Kentucky, Massachusetts, and South Carolina), insurance companies are required to allow people with anti-compression insurance to pay for the replacement of an additional windshield with no deductible in their policies. However, some conditions, such as negligent driving and some specific types of damage, can deter warranty companies from covering windshield replacement or repair costs.
GEICO and Progressive require that you have comprehensive insurance in order to replace the windshield with coverage. Liberty Mutual follows a comprehensive coverage model for windshield replacement as well. The best way to get a lower price on your windshield is to compare prices with at least 3 local windshield companies. Many car warranties only offer the possibility to repair or replace the windshield if the damage occurred on your part, for example, if the damage was due to a manufacturing error or a problem with the materials.
