Be prepared for a stressful argument with your dealer when claiming for EXTENDED warranty repairs!
A close family friend bought extended warranty for his Chevy Venture. Regular warranty has lapsed and extended warranty was in effect when he had problems with the van. He took it to GM Goodwrench and they happily serviced the van, knowing that it's under extended warranty. When it's time to pick-up the van, they wouldn't release it till he pays $800! Based on the fine print, their extended warranty claims are valid. They had a very long argument about it and he had to bring in reinforcement... his wife! Then later after more arguments ensued, the service agreed to release the van for 0 dollars.
From that day on, they've become anti-extended warranty anadvocates, telling friends and relatives to think twice about it.
