Well, 93K and I had component failure!  Drivers side Tie Rod/Outer Bushing gone....I do have a Hellwig sway bar on the front so that probably aided in it's life expectancy even though I pump/condition the joints.  I will take damage for having the Hellwig sway bar though.  Looks like now will be first alignment job on Truck after I put the Tie Rod ends back on......on to 100K

thanks!     My truck has no mods.  AFM is enabled, no catch can, stock everything.  Once it warms up ill give it some fresh plugs, fluids and a level.   IMO the key is to keep it c

2016 Silverado LTZ Z71

5.3V8/ 8 Speed Tran 

92,364 Miles

 

So far nothing but routine maintenance and recalls. Plan on doing a transmission flush and coolant within the next month. As well as brakes shortly after. 

 

My pops had a 2015 High Country that the radiator went at 120k. Like his mine is a lot of highway miles.

I have a 2014 CC Standard Bed 4x4  5.3 v8 Currently 184K

 

I lost AC condenser/transmission cooler around 100k.

Had an alignment done after a level was installed around 110k

Factory battery was replaced also around 125K.

I replaced all brake pads and rotors at 175k as I had developed a bit of brake shudder in heavy braking.

Been running slightly larger than stock tires on stock wheels since about 80K

Change oil every 7k 0-20 Edge. Fram Filter.

 

Other than that I'm averaging 18.6 mpg mixed higwhay/2 lane/city driving.

Sounds pretty good!  No lifter failure? No vacuum pump failure? So pretty much the weak link on K2's is the AC system.  Typical GM fashion Solid Engine/Trans!

2015 GMC SLT just passed 138,000 miles.  Like many owners I have replaced the air conditioning condenser.  Have replaced front and real brakes.  General maintenance beyond that.  Very happy with the truck so far.  Hoping for another 70K.

Nice sounds like a GM truck owner hoping for another 50-70K course your gonna get that you know that!

Neither of which may classify as "high miles," but.....

 

Bought my 2015 in December 12, 2015.  When it was totaled on July 1, 2018, it had 53,XXX.  Only serious maintenance was tires and new front brake pads (at 50K).

 

Bought my 2018 in September 15, 2018, 21,400ish as of today, 16 months of ownership.

I just bought my 2016 Sierra 1500 Elevation with 124k on it, good deal with trying to push cars off lot because of pandemic. 

 

Minor problems, such as rear brake line needed to be replaced (stretched and snapped?) , AC condenser needed to be replaced (hit with a bird at some point), and needed a crank shaft position sensor replacement that the dealer replaced all before taking off the lot. Put 1000 miles on in the last 2 weeks and its been running great, I did get a 100k service contact and am somewhat mechanically inclined if there are problems later. All maintenance records point to last owner keeping up to date on recommended maintenance at GM intervals.

2014 GMC Sierra 5.3L with 178K, replaced 1 transmission, 1 AC compressor, 1 radiator, 4 oxygen sensors and catalytic converter currently the radiator fan is constantly operating and temperature gauge won't leave 165F - probably needs a new thermostat that my local supplier doesn't have in stock....other than that it runs great.

The title says high mileage.

If you got 40,000 miles on your 2015, I don't care. Don't bother posting. 40,000 big deal.

 

If you got 200,000 miles on your 2015 that's what we are talking about here.

2015 Yukon, 5.3, bought with 111k, AFM disabled when I bought it via HP tuners, it now has 135k, it’s had the AC condenser replaced along with every single fluid and filter changed when I got it. I put in a lower temp trans thermostat and new transmission cooler lines (rubber was leaking). Here in a couple months I’m replacing the water pump, putting in a CTSV thermostat, radiator hoses and max tow radiator (thicker than the base radiator), all OEM, I do a lot of towing with our camper all over the US so want it to be ready and reliable for the summer time
