Not sure if it's bragging or too poor to afford a new one. Just hit 300K on 2014 GMC All Terrain CC 4WD 5.3v8.
Truck is basically stock. I purchased it in 2016 with 51K on it. I immediately did oil change with Edge motor oil. Have used Edge the entire time changing at DIC stated intervals. A time or two I have had low oil message on DIC. Either went in for top off or just got oil changed. Wix filters were used up until 3 oil changes ago and my local oil shop was bought out by "Take 5" Now I have no clue what filter or oil they use. They stated it was equivelent to edge...I'm sure it's probably junk and I'm looking for a new oil shop.
Part failures that I can remember:
Air condenser cooler went out at 115k. I replaced it myself and I guess I broke a clip at the trans coolant line. That clip let go about 15k later and dumped tranny fluid all over I75. I buttoned it all up and then at 140k Tranny went out (was probably my fault) A/C delco tranny in at 140k. Brake pads at around 180k, Starter around 200k, Another transmission at 236k that was covered by A/C delco as the replacement had 100k warranty and didn't make it. Second Air condenser at 245k. Front pads and rotors around 250k. about 4 sets of wiper blades, 2 batteries. I have a grounding issue that I think is in the negative battery cable. Starting to get intermittent no start/dead battery issues from time to time....re-adjust negative battery cable and it starts right up.
With all that said. it's been a great truck. I've been from Mid GA to Colorado and South Florida to DC is this damn thing. Also, during 2021 it basically sat for a year except for vacation trips (so maybe 7000 put on truck in 2021) I had a company vehicle.
So, I'd like to sell it for 37k that I paid for it in 2016. It's definitely reliable. I'm wanting a 24 2500 so bad...but dang they are spendy.
