Hey guys I’m in the market for a Suburban, I already have an 08 Tahoe so I’m familiar with some things like AFM and the torque converter weakness of the 6l80e.
As I’m shopping around for 2015+ Suburbans what are other quirks of the platform I should keep in mind for long term ownership.
Thanks!
just maintenance like any other vehicle
there are some that have some roof noise that is heard while driving, apparently it may have something to do with not enough glue used in the panels
8 speed should be avoided
some have had failed ac condensers, which was covered by gm at one point
some have had fuel injector issue's, the one I bought my wife had a special 10 year coverage and all of the injectors were replaced under that coverage.
the oem suspension (shocks) are not as robust as the gmt900's some have reported the shocks failing starting at about 45k, versus the gmt900's were typical of 85k+
if you are shopping used, check the transmission fluid we saw a lot of them with burnt fluid, practically all of them....
also check all the buttons, switches, door locks, windows, sunroof, mirrors, power folding seats, screens, sensors and gizmo's BASICALLY everything, if you find one that has everything working your lucky.
also note that the act of just opening a door on a k2 can wake the system up, that's normal, found that out when these were out on display in 2014
at minimum just opening the drivers door will display the mileage on the cluster briefly, the fuel pump may prime and you may hear other clicks and ticks, the radio may come on or light up, etc. that is because of the "most buss" which is a special connection between the radio & cluster & bcm.
so if you see one out on a lot and just want to check the mileage all you have to do is open the drivers door and look at the cluster, it only shows for a few seconds, you don't need the keys as long as it unlocked.
your 2008 will show it also, but you have to press the black button in the upper right hand corner of the cluster, no keys are needed
