On my 2006 Avalanche I've been noticing the plastic wire loom has been breaking off exposing the trucks wiring. Found most of this in the engine bay but a few other places underneath the truck as well and in the cab. This actually caused me to lose my gas pedal position sensor. Might want to start taking a look at the wiring in your truck too. My truck is garage kept in the south but age gets everything.

Had the exact same thing happen with my 2012. Heater went out causing the slow limitations of death. Part was covered under the extended warranty but was on national back order. Traded the Duramax in for a GMC 1500. Would love to get back into a Duramax but don't really want to deal with the emission systems again.

Am I the only one who stopped at "I changed the front hubs and noticed a slight vibration"? Sounds like you caused this with the hub install possibly? You didn't state if you had a vibration before or just bearing noise.

In the signature is says 14 Sierra SLT

I almost feel as if this is normal operation thanks to their harness. They use a relay setup I think so it would make sense the headlights would only come on with the ignition on. Rather than use capacitors to make up for the pulse width management they used relays. Personally if you have an SLT truck the harness they sell is over priced and over kill for what you need. You only need two small harnesses with built in resistors and capacitors along with the correct plugs to make the new headlights plug and play while retaining all normal OEM functions for your 2014. Zmnypit is the creator of the harness I am talking about.

Can't comment on which circuit, though they had install instructions on the site where you buy the harness I think.

I feel like that's the game today. Newer trucks make us feel like we should invest in a cheap commuter car because when our trucks are working they're great. When they break.. man do they break. Just hoping for more use out of my 06 Avalanche.

Are you 2wd? Thought the rear diff used 75-90 or something. 80/90 for the front sounds right. I figured I would wanna go after GM fluid for the transfer case. Had to do that with my 09 Ram that had an auto select transfer case. It was very picky on the fluid.

I need to do that as well. What fluid are you using for the transfer case?

While they sure look good I don't have that kind of money to drop on those. I really wish I did though.

I wonder when they will get this straightened out if ever. Kind of saddens me to think my 2015 will have this issue eventually. With 21k on the clock and just over 18 months of trouble free ownership this stinks. Makes me glad I have my 06 Avalanche as back up for now.

Honestly this is one of the reasons why I have a dash cam. It can't see much with the hood popped but it can see if a hand goes for the oil cap.

Hmm. I have just now noticed the slow throttle response since I am switching between a 2006 Avalanche and 2015 Sierra. While I didn't think the response was that bad I might jump on this crazy train to see if there really is a difference to me.
