Replaced the negative ground wire. Used degreaser to clean the frame, screw and the hole. Cleaned the end of the ground wire located on the driver side and the frame there too. Removed and cleaned the positive cable and reconnected. Thanks for your input. We are here for assistance.When anyone is saying "cleaned", how are you cleaning it? If you are just cleaning the outside of it and not removing the bolt(s) and then cleaning all connections and the mounting surface, you are not cleaning it. Salt on the roads states are a blight to those grounds. People keep saying they are removing the negative battery cable and cleaning or tightening, what about the positive cable. ALL wiring that you remove should be inspected closely for corrosion getting under the end of the wire insulation. Not just cleaning the ends. Also, check at the fuse/relay box under the hood. Do a search for threads about finding connection problems there.
After finding and doing all that to all the ground locations, or even before that, I would check out the fuse/relay box under the hood. Do a search for those posts about all that.Replaced the negative ground wire. Used degreaser to clean the frame, screw and the hole.

Power loss
2015-2020 Yukon
My 2015 Yukon loses power when hitting bumps. When cornering the wheel automatically overcorrects. I changed the negative battery cable but the problem still exists. Anyone has these problems, if so what was the fix. Thanks in advance
My 2011 just did this, wife went over railroad track and said that the door locks clicked, dash lit up, and steering and brakes were extremely hard. She coasted a bit, then it all came back on. Dropping at shop now for some electrical diagnostics, not very optimistic though.
Have u noticed your headlights dimming and ac fan sort of browning out from time to time?

Boogie woogie woogieWithout knowing the internal trouble codes, I would say your problem lays within the steering motor and wiring, it's electric.
Cleaning it with degreaser or hitting it lightly with sandpaper to make a better connection?Beat me to it. Sounds like OP's actually cleaning the connections, though. Good to confirm this.
@jerwilso, I agree with checking the fuse & relay center. Try to knock it around a bit with the key on and engine running. See if any of the weirdness happens.
