I'll chime in. BULLITT65, there is a bulletin about the taillight. Mine was doing the same- off and on. They replaced it for free out of warranty.
Issues my truck came with initially was a glitchy center display- bad cable. Clunking torque convertor; sometimes makes quite a bang releasing while traveling down a hill- never fixed. Squeaking front suspension- after 30k miles finally decided to change front suspension bushings- fixed. Takes a while to engage drive after shifting out of reverse especially during cold temps- never fixed.
The OE tires are horrible FWIW. So I'd say any used Denali should have replacements on it.
I never encountered the booming as many do. It does make an odd sound that can hurt your ears with the sunroof open. But many large SUV's do that. The back of these things is like a huge cave. Crack a rear window and it goes away.
The AFM is horrible as in several GM vehicles I have owned. I would highly recommend the BB tune to eliminate it. I didn't notice any lack of mpg savings for my style of driving by doing so.
Mine just started a weird vibrating in in the past 3 months which may be the drive shaft. This should be covered by the powertrain warranty.
Besides all that...it is still my favorite large XL SUV. If I was in the market for a regular sized SUV (Tahoe sized), I'd probably test drive some different vehicles. Large SUV's are far and few from manufacturers. 'Regular sized' SUV's are much more competitive and plentiful.
