Just sold our 2013 3/4 ton Suburban as someone made me an offer I simply couldn't refuse on it............was an LT, purchased with 65k, sold with 95k, lots of Wife is currently driving a spare vehicle (2010 Chrysler Town & Country) until this Fall, when we'll look into another large SUV for hauling 3 kids and gear around in Michigan snow. The Suburban we had (GMT900 chassis) was only "average" for reliability, which irritates me to no end for the money these vehicles cost, but there are only a couple large SUVs that have any cargo space behind the 3rd row, so I'm kinda stuck. I'm honestly concerned about getting stuck with a used "problem" here, but don't have many other options. ie, she likes the larger SUV in the winter, versus an AWD Sienna. The Land Cruiser and QX80/Armada are too small in the cargo area, Expedition MAX is nice but enormous $$, etc. I'd like to spend about $40-42k to spend on a vehicle, which is 2015 Denali XL/Suburban with 75k kind of money. My parents had a 2015 Escalade ESV that had a torque converter replaced (shuddering issue) at 18k, rear differential recall, rear wiper failed within the first week, and the side B trim moldings kept falling off. They decided not to buy it at the end of the lease. They replaced it with a 2015 Denali XL (purchased sight unseen used online) with 45k this past spring, and it rides and drives fine, no issues. **I prefer the 6.2 engine and the Yukon front clip, so I think I'll aim for a Denali XL** My concern areas: 1) Booming/Buffeting/vibration issues (we *very* rarely are able to drive over 60-65mph where we live, so I'm not sure how much of an issue this is? 2) I've read of some engine failures on the 5.3 (and lots on the previous generations due to oil starvation with the AFM system, but I'm looking for a 6.2 anyway....... Any issues with the 6.2? 3) Torque converter issues like my parents had on their '15 Escalade? 4) Have read lots of threads and reviews about A/C failures....... 5) Friend has had constant issues with the tailgate latch not opening on his '15 Suburban....... Anything else? Thanks!!
