So a couple months ago I bought a Certified 2016 Tahoe LT, Luxury package, Sun entertainment package, Max trailering, Second row buckets, 20" Polished aluminum wheels, Splash guards, Siren red tintcoat. Unfortunately, as soon as I saw this truck with the CocoaDune leather interior and literally not a mark on it, I wanted it. The original sticker was 65,500. They had it up for 43,000 and I got it at 41,000. It had 28,000 miles on it. Anyhow, since I bought it in cold weather I didn't try the AC, so now the weather warms up and I turn on the AC and it just doesn't seem to be blowing cold. I pop in a dash vent thermometer and it is showing 60 degrees. So I join this forum and discover the now well known AC condenser issue and am kicking myself for not doing any homework and falling for this truck as soon as I saw it. So off I go the dealership armed with all the info and the extended warranty number and my certified warranty info ready to do battle. Well, the techs in service could not have been more helpful and listened to me patiently and told me that obviously they would dye test the system and check the well known issues, BUT they have been seeing leaks at the rear evaporator which I never heard about. And that was the problem. The other stuff will probably fail eventually, but for now it was the rear evaporator. Of course all was done under warranty and they gave me Z71 Colorado as a loaner. I did have a discussion with my sales rep and the used car mgr. suggesting that this vehicle should never have been put up for sale without checking out the AC. Of course they were all apologetic and said they would add that to what they do in the future. I also said that the NAV systems should be updated on Certified vehicles, but they wouldn't go that far. Thanks for listening to me vent at bit, but I still love this truck. Coming from a 2005 Hemi Durango that I put 150K miles on, this Tahoe is a dream.
