Powertrain Poll
All warranties are based on the notion that the company will likely never have to pay out a claim. The change could be as simple as following the lead of the industry and as complex as the bean counters minimizing exposure and/or following ownership trends. I'm mean, how many people are driving their cars to 100,000 miles before trading them?
The first criteria for determining warranty length and coverage is 'what does the market require?'. It's really a marketing decision at that point. (Think Kia and others - they needed a 10 year warranty just to try and gain a foothold in the market because no one in the US really knew them).
The analytics my company provides includes a very accurate estimate of warranty costs for specific warranty terms - broken down by model/sub-model, components, etc.
The range for warranty expense per vehicle starts at about $750 per vehicle on the low side, and up to more than $5000 per vehicle on the higher side (this is for 'mainstream brands' - not the more exotic brands like Ferrari, Lambo, etc.). The range is driven by a number of factors such as vehicle type, drive train (fuel type, S/C, T/C, gas, diesel, and so on), usage, region, term of warranty, components covered, and on and on.
One of the reasons that automotive companies don't like to have a limited warranty length any longer than is needed in the market is because they need to carry the liability for the warranty (the $750-5000 I mentioned) for the life of the warranty. In the case of our C7s, the warranty liabilities are split into two: bumper/bumper, and drive train. They earn the liabilities as time elapses, but the unearned portion remains on the books and this is a pain and large financial burden.
Completely on a side note, I grow weary of a few forum members that post how terrible GM is compared to other car companies. "I'll never purchase another GM car", or "This is the only GM car I would ever purchase because I had a terrible experience in 1984 with a (fill in the GM blank)", etc. The globalization of the auto industry has forced increased quality across the board. And I can say with absolute certainty that GM vehicles perform better than the industry/category average for warranty costs/vehicle, and much better than many so called 'quality' brands. Internet 'facts' die hard sometimes.
Have a few owners had troubles with their C7s? Absolutely. Have some had a horrible dealer/service/warranty problem. Undoubtedly. But the vast majority will never see any warranty issue of any consequence, and those that do will be covered. Our C7s are one of the best all around values on the planet - certainly in the sports car category.
