Well, I'm kinda proud but it seems conservative driving and LOTs of maintenance can pay off. Now that I've fixed all the known problems, it seems i have a dependable vehicle that i can just drive and enjoy. View attachment 379233
Awesome! I am at 120k on my 2015 Denali. Lifter replaced about 75k, new trans at 15k, couple fuel pumps, MRC shocks, 2 gps antennae, condensor, trans temp sensor and some other stuff all under warranty.

I’ve replaced trans fluid every 45k
Diffs and Transfer case oil 2x
Plugs and wires at 76k

What all has failed and or been repaired to hit 300k?

Thanks!

Hi, and yes i was expecting that question. Here goes:

Torque converter (warranty)
radiator ( warranty)
a/c condenser ( warranty)
left running board motor
right running board motor
trans temp sensor 2x
another condenser
3 more radiators
cam
all lifters
all 4 magnaride shocks ( converted to hydraulic )
2 batteries,
gps antenna
reflash 4wd module
front cv boot
front sway bar mounts
plugs
starter
2 sets replacement tires
front rotors and pads
rear pads
change trans fluid every 40k miles or so. (Mobil blue label)
learned my lesson about oil changes: was doing every 10k, now i do 5k changes only.
Thanks. TG

So you’re still on the original transmission? Just second converter.
Do you have the 8 speed or the 6 speed?

2 sets of replacement tires… as in you’re on your 3rd set? If so that’s some really good mileage you’re getting out of your tires! Brand and size?

That seems like a lot of radiators?

When you replaced the cam and all the lifters I’m assuming that repair was completed at the same time? If so curious why you didn’t go ahead and mechanically delete the AFM?
