I leased a Cadillac Escalade EXT for 3 years now and I will never purchase one again! after the 80,000 KM warranty was up the diferential berrings went along with wheel bearings. Would GM help? NO! I was at 82,446 KM and they wouldn't even split the bill. Things continue to break. Now a front shock air bag is punctured and not covered by the warranty. Here's my answer to GM. I have been faithful for the past 20 years, but no longer. Good luck with this Escalade when you get it back, becuse now you can pay to fix it!
