Loosen lugs and let car roll about 10’—slam on brakes hard, works every time

I have solo performance on my 2014 5.3–all stainless and no drone at all—if you have longer wheelbase they will add extension at no charge https://shop-solo-performance.com/en/silverado-sierra/1821-239-v8-pontiac-g8-2-kooks-to-solo-converters-and-catless-pipe-adaptors.html#/301-choose_preference_for_solo_mach_44_53l_1435_wb_dual_exhaust_-chevy_gmc_mach_44_dual_standard_tips_77490

Curious if anyone had the issue I ran into—2014 High Country 4x4 5.3–flipped the pill in the thermostat just like everyone else, re assembled and was leaking bad from cap—took apart to see if I didn’t assemble correctly, all looked good—made sure half moon on cap was facing lines this time—installed again, same leak—tried a 3rd time, this time it shot the cap off and it landed on top of the transmission!, Took apart a 3rd time, re assembled back to factory setting, installed and works fine—- Any thoughts?

Yes, power sears (also heated and cooling) all seats function has normal

2014 High Country (5.3)—found this plug a few weeks ago under drivers seat and cannot fine what it plugs into—everything working in truck (or so I thought)— tried to use USB and 12v port inside console and none work—pulled out the USB ports on one side of the console and 12v lighter on other side and neither getting power (checked with both ignition on and off)—checked fuses, all are ok—guessed this plug may have something to do with it so checked it for power and it does get 12v—look under passenger seat and same plug was laying on floor!!! Anyone aware if these plugs are for power to the console and if so where they plug in? Any help appreciated!
