    2013 Yukon 5.3 Lifter Noise

    I have a 2013 Yukon SLT 2WD 5.3L with 143,800 miles on it. I believe I have what is a lifter tick on the passengers side. AFM is not disabled. I am basing that on a 2002 Tahoe with a 5.3 I had that I knew had a bad lifter. Once the engine warms up you can hear it. The only time you cannot hear...

    2013 Yukon Rim Swap

    Would it be possible to swap new 20 inch GMC rims onto my 2013 Yukon SLT 5.3L 2WD and be able to reprogram anything that needs to be reprogrammed so I have accurate speed readings and air readings for my tires?

    Door Lock Issue-2013 Yukon SLT

    I am experiencing a super weird issue with my key fob: So when I go to unlock the Yukon when it is sitting locked with the key fob the drivers door will not unlock. But all the other doors will. When I got to get out the car the door unlock button does not work. So I have to slide up the black...

    2013 Yukon 5.3 SLT with a 6 speed

    It was done first at 26k, 63ishk, and then around 80-82k. So then ya it probably needs a service then.

    2013 AFM DISABLE

    Disable I think would be the cheapest option. I think the leading requires rebuilding the motor partially.

    2017 Tahoe DFM delete

    One of my family members is looking to do a DFM delete on their 2017 Tahoe 2WD with the 5.3L. It has approximately 88,000 miles on it. Do you guys have any recommendations for plug-and-play devices? Also have you noticed any negative impact on your gas mileage?

    Later model transmissions issues

    What has been the experiences with the later model 6 speed transmissions with the 5.3L (2010-2014)? Has anyone had them go out? Any major work beyond normal maintenance? I know the 2007-2009 had some pretty serious issues but I was told it was fixed in the later models. A relative of mine had...

    2017 Sunroof Issues

    Has anyone had any issues with their sunroofs where water leaks in and soaks the headliner? It only happens when it sits out in the rain at a certain angle. It’s on a 2017 Tahoe. It has been taken to the dealer numerous times and they cannot replicate the issue.

    2013 Yukon

    I think it should have the tow package and a heavier rear end. I would probably get as big of a boat as I could and still be safe at the boat ramp with a 2 wheel drive and good tires. Maybe something that can make it off shore a little bit.

    2013 Yukon

    I have a 2013 Yukon 2WD with a 5.3 and I was wondering how long they typically last? The only major problem I’ve had with it is the catalytic converter‘s had to be replaced but but I was told it was probably from a misfire before I bought it used. That was done at 112,000. It currently has...
