I had my cluster pre programmed for hud. My slt has the heads up led brake assist so I think my windshield is compatible. Even with this kit you still have to cut your dash and fabricate a new cluster cover and upper dash trim? I’d like to have hud but don’t want to saw my dash [emoji22]
Here is the TSB with the voltage drop test, Dash grounds G218 check, and starter heat shield shorting out on starter solenoid positive cable. https://static.nhtsa.gov/odi/tsbs/2019/MC-10168185-9999.pdf
Is your issue still fixed? I have a 2018 and get service stabillitrack randomly and immediately after startup then disappears. No other messages. The G18 dash ground should not be an issue on my 2018. I did clean the negative battery cable frame ground on the passenger side frame rail near the front fender liner. Mine had a decent amount of wax blocking the connection. Haven't seen the message but its only been a week.
Sorry to hear about the mishap but unfortunately happens! id suggest the following: 1. Dr colorchip 2. Decal 3. Repaint. It will be hard to match to rest of truck since it’s a dark color and several years old But it doesn’t have metallic flake in it so that’s a big plus on getting the new paint to match very close to the 2014 paint. Don’t beat yourself up too much. We’ve all had similar moments. Let us know how it turns out & Good Luck!
My truck is a 2018 so it shouldn’t need the dash ground fix. I’m not having power steering issue but occasional service stabilitrack message in the DIC immediately after startup then it quickly goes away. The passenger frame ground had a decent layer of wax between the cable and frame. I cleaned it up with a paper towel. Issue hasn’t returned yet...
1st pic was what it looked like from factory after I removed 10mm bolt and neg cable. 2nd and 3rd pic after I wiped off wax with a paper towel. Will have to give it a few days or weeks to see if I get service stabilitrack message again.
My neg cable didn’t even register a DC mv reading. My pos cable was 5.53 with a jump to 11.65. Got a low battery alert which also notified onstar? after doing this test. I got an diagnostic email lol. Battery voltage is 12.62 so maybe my battery is weak? Or my random service stabilatrack message is a different issue.
Get rid of the spacer and add bilstein 5100 which will level the truck and give you an extra 1” of travel in the front. I’m running 5100 with 1.8” lift in front and stock height In rear. I have a slight rake which I like since I tow and don’t want to be nose high. I believe you can raise front 2.25” with 5100.
Thanks! I have been getting a service stabilitrack on the DIC randomly on startup. Disappears quickly before i can Dismiss. Happens randomly once or twice every few months, only during startup.
2018 6.2L 8L90 13k miles no issues.
Personally I’d wait. New interior in 2022 models. Most likely slightly refreshed front and rear clip as well. Your truck will be worth a bit less the longer you wait but I’d say it’s well worth it since 2022 models will be released late spring / early summer 2021. Used vehicle values are high during this pandemic which will be with us for awhile longer.
I sold my factory 20”s on craigs and picked up a set of 18” AT4 wheels off of a 2020. FYI any oem GM 6 lug wheel 2007 - 2021 off a full size suburban, Yukon, Tahoe, Silverado, Sierra, Escalade will fit your K2xx. Must be 17” or larger wheel to clear the front brake calipers. Factory spare is a 17”. Don’t have to worry about offsets when using a factory wheel. Colorado canyon wheels will not fit as they changed the bolt pattern.
