2017 GMC Denali 6.2 , after my truck sits for a few days and i start up i notice a small puff of blue smoke coming from tail pipe.

My experience from other vehicles is that is usually an indication of oil seeping past valve seats. I have noticed that on other vehicles before ,but usually high mileage vehicles my truck only has 14K miles.

Has anyone else noticed this or have and suggestions if that is normal for new engines or should I be concerned ?

  On my 2011 Sierra 1500 I had all kinds of lighting issues on the stereo head unit. Turned out there is about 10 or so soldered connections on the head unit that were in various stages of cracked. The solder guy fixed that up a couple years ago but now the rear speakers aren't working. Might be the same thing. Every so often the speakers work. Jim

  So I was going to go for a drive in the 2011 GMC 1500 at 4am but when I started the truck, no low beams. High beams work. Separate bulbs. Now what. Google says that sometimes when one bulb goes the other goes in sympathy. Who knows when they went out. Did some testing. The connector that plugs into the bulb had 12 volts. The bulb showed open circuit implying that the bulb is gone. Replaced one bulb and it worked. Can't get the other bulb out of the headlamp assembly so have to remove the whole assembly. That will be in a couple days. Other things to do. Got it though Jim

  After talking with a GM tech, that seemed to know what he was talking about, he told me to put a trickle charger on my battery overnight, that most always when the check for updates is greyed out, that means the battery needs extra charging, and according to him, its a battery in one of the modules, not necessarily the main starting battery. I did this, and then took a 10 mile trip, and when I shifted to park in my garage the message popped up to install the update, which installed successfully. I still don't have a couple of the latest updates from what I've seen, but maybe they will install now at some point.
