When looking at used, I drove a number of Tahoes and Yukons specifically looking for known issues. Didn't really know what I was looking for until I drove a Tahoe that had just come in from lease. There was something off a bit with that car from the moment I started it and drove off the lot. I couldn't even complete the test drive because I became so nauseated. From my experience in test driving, cars either have it or they don't, not sure if they will develop it or not. I looked for a year until I found a '16 Yukon that checked off most of my wish list - gave up the 20" tires for 18's but oh well. I've have it 10 months, put 13K miles on it and am very pleased with my purchase.
