I had the battery and alternator replaced 09/2007 here in northern Canada and while driving in southern California earlier this month I had to have both replaced again after both failed (while waiting in line at the border to enter the U.S. from Mexico... after two jumpstarts I hooked my tow rope to the front of my 2001 Suburban and a new Ford Excursion appeared eagerly to the rescue). So I get yanked across the border, have to push the truck through secondary to get to where the tow truck can access it, and end up at a nearby Chevy dealer. Two days, a rental car, and several hundred dollars later, the new battery and alternator are installed but only the GM Canada battery is warrantied beyond 12 months. The U.S. alternator carries a lifetime warranty for the part (and lifetime on the labor by the dealer, not sure if this applies at every GM dealer in the U.S.). Unfortunately there isn't a GM dealer across the border from me in Alaska otherwise I'd be getting parts and service there, where many of the parts carry a lifetime warranty. But with most of Canada's population living a short distance from the U.S. border, why wouldn't we choose to have our vehicles serviced there rather than in Canada? Especially with the dollars nearing parity? I contacted GM Canada about the issue but I don't expect much in response. Besides this forum, perhaps Consumer Reports should be notified?
