AUL Auto Warranty Sold auto warranty to cover the entire vehicle and will not pay any claims! Napa Nationwide!!. Purchased an extended warranty plan for $3,500. I paid for every option available, including the enhanced electrical policy. They denied an electronic module that controls the blinkers, gas gauge, and hazard lights claim. They denied the claim due to some corrosion on the wire. The module is inside the rear quarter panel of my ML350..This is a classic case of a perfect warranty scenario.. No where in the contract did it state it would not cover any electrical component due to corrosion or whatever reason they deem necessary to deny the claim. I was told everything was covered with only a $100 deductible. When the service adviser called me AUL He told me they would not pay for anything, and they have the right to deny ANY claim. Very RUDE and basically only left me the option to sue them in small claims court. I was very courteous and respectful on the phone, however the representative that called me was very cynical and rude. A complete rip off company.. Extended warranties are for peace of mind in case the out of ordinary malfunction or repair happens to your vehicle. I realize they all have some restrictions but in my case purchasing the enhanced electrical policy that cost more should cover an electronic component that no one can access or knows exist.
