Another option to consider for some people
Personally, I hate the idea of extended extra-cost warranties. It's like the manufacturer is saying, 'we're not going to be responsible for the quality of our product -- so you'd better spend a couple of thousand dollars more for insurance -- and then will try to find loopholes to deny your claims whenever possible.'
That's one reason I love Hyundai, which used to make lousy cars, but implemented a 10-year warranty once they improved quality to back it up.
Anyway, the real point of this post is to remind those of you who are also GEICO policyholders that they have a much less costly extended warranty program that provides close to the same coverage as a typical one from a dealership.
The cost is often around only $60-$70 a year, though I don't know exactly what it is for a Traverse, and it is "exclusionary," insurance, which is good, because that means it covers everything except a few specifical exceptions -- typically just normal wear and tear (tires, oil changes, etc.)
However, the one big difference is a high $250 deductible, so it's not everyone's cup of tea.
Still, it's worth closely comparing the cost and the fine print with the GMPP, I'd say, to see which you think would be better for your own situation and peace of mind.
