BOAT Load of codes!

[Tangojay]

This mess started with a “stabilitrak” warning plus “parking assist “ disabled, I tried unhooking battery ( only negative) and all was well,, until a couple of days ago, they came back, plus the cruise control does not work. I bought a new code reader (the one I had was bought around 2012) and it gives me 33 codes! Here are some codes,,,

I’m pretty sure GM had a recall on a ground for a similar situation

Typically this means bad ground/power, pinched wire, bad battery. Especially when you get a laundry list of codes

Look up G218 Ground fix if it doesn’t apply to your models or years you might have something expensive going on I know atleast 2014-2018 has issues with (stabilitrack) or masses of codes that can be directly related to that ground

As @Doubeleive stated above, whenever you get a sudden slew of codes popping up, it is generally related to your electrical system. More specifically, (1) your battery may be failing, (2) your battery cables may be failing (they rot from the inside out), or (3) bad or broken ground strap or frame connection.

Check out these 3 sources of this issue, and more often than not, you will find the root cause in one or more of these 3 areas.

Most of those codes are historical and now meaningless. A battery change or jump start can cause those to set and then they go to history after passing one or more self-tests.

Write them all down and focus on the active ones.

Could also be a bad module corrupting the canbus. Happened on my 2015, ended up being a bad side detection module.
