When I open the door to my Yukon while it's in the garage, I hear the Nav/DVD making noise like it's reading the DVD, you know that CD/DVD noise it makes when it's accessing data. Is this normal? This is with the truck ignition completely off.

 

I've left my truck parked for over two weeks while out of the country and it started right up, so it doesn't seem to be draining the battery.

 

 

Other question is under moderate throttle around 2,000rpm give or take a few hundred rpm on either side, my engine makes a bit of a rattle noise like something is loose under the hood. It's a resonance type rattle and it seems to happen pretty much all the time in that rpm range with medium throttle. Someone posted up a TSB a long while back about the right wheel fender area or the radiator fluid container rattling, but I can't find it. Anyone experience this and/or know a fix?

 

Otherwise, I have 25k miles on my '08 Yukon and she's been flawless. I love her.

Yes, the noise from the NAV unit is normal. Mine does the same.

 

Not sure on the rattling, I would have to hear it to know if it's "normal" or not.... but keep in mind that a bit of resonant drone should be expected as normal under certain acceleration conditions from the large V8 in that truck. At cruising speeds it should quiet back down though.

The Nav will make that noise any time the door is opened. The first few times the wife's Tahoe did that it threw me for a bit of a loop as well. As far as the TSB, I think the bottle was contacting the fender so you could try some 3M double sided tape to act as a cushion. That might work. :lol:

The rattle noise your hearing if its the same alot of us had is the heat shield under the passenger side at the exhaust by the motor, I had the same noise and with a couple of hits with my hand to bend it a little problem was solved.

thanks for all the suggestions, I will give the double sided tape and also the heat shield a try and see if it works.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because it’s in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
