Good Day, Desperate to find some help here. 2014 Silverado 120k Miles, 6" lift and 35" tires bought from very large lifted truck dealer in Arizona in 2018, It does NOT have trailer braking however an aftermark trailer brake is installed. NOTE: I have not yet replaced the battery which is 6 years old a Few days after purchasing I started getting stabilitrac warnings on bumps, dealer replaced wheel speed sensors claimed it was good to go. 6 months later it started happening again, I replaced them again myself and within weeks the problem returned... Since this last winter my truck is electrically falling apart the ABS started firing when it should not, even at low speeds, I had to pull the ABS fuse/relay just to safely drive, then the parking sensors started throwing a service system warning and now don't work at all, the 4 x4 warns it needs service but still works fine, and now the final issue that is making me lose my mind is the parking/e brake warning light dings almost constantly, even at high speeds though it does it less, the parking brake is NOT engaged.. In addition the brake warning is followed by the "steering assist reduced drive with care message". though I cant notice an issue with power steering.. Any feedback is appreciated I am losing my mind, I will be replacing battery by this seems a little much for just battery, I have read about the ground issue could that be it? Bad BCM, or ECM?

Good Morning, I joined specifically to see if anyone could help me figure out the issue that has me ready to rip my hair out. I have 2014 Silverado LTZ with a 6 inch lift and 35 inch tires, a little history may be important. The day after I bought the truck I started getting stabilitrack warnings when I would hit a bump, train tracks, etc... Took it back to dealer they replaced the wheel speed sensors and problem went away for a month or so and then came back occasionally I did some googling and found this can be potentially related to the lift, I replaced the Rotors and Pads with beefier setup for towing our camper over mountain pass and decided since I was already down there to replace the wheel speed sensors myself a couple years later. Not much later I began having issues with the ABS firing when it shouldn't and major braking concerns along with the stabilitrack firing non stop, I live in a very mountainy area and this was getting dangerous with the amount of snow we get so I pulled the ABS relay and the issues with ABS firing went away I just had the ABS warning light come on... now over the last 6 months I have added to my warnings - service 4wd (still works just fine), Parking sensor warnings off and on (sometimes they work sometimes they dont) and the worst one is that now while I driving about 10 min or so after starting I get non stop off on chimes from the parking brake warning along with the light flashing, it will go away at High Speeds but it is driving me absolutely insane. I will say that my battery is 6 years old, i checked the voltage and it is within normal range, I tried pulling the negative cable for 20 min to reset things and all of them came back, I am at a loss.... I did find a forum where someone said that the brake light/reduced steering issue was ECM, given the massive amount of issues I am inclined to believe but wanted to sanity check before i replaced it. Thanks in advance for the help.
