    2012 Tahoe.

    This has happened before and they told me there was a wire grounding out (not sure which wire). Can’t accelerate without the truck stuttering and the electric going in and out, and the power locks locking and unlocking rapidly. Sometimes won’t start.

    Thoughts?

    Any help is appreciated.

    Thanks

    I would start first by checking the battery cables and mega fuse connections

    Battery cables looked good. No corrosion. Will check the mega fuse in the morning. Thanks.

    You may have already done this but when checking the battery cables, make sure you look at the surfaces that are mated at the connection. I’ve had cables that looked fine only to find that there was a crust of corrosion under the connector at the frame.

    Thanks. I thought maybe just disconnecting the pos. battery terminal made a difference because it drove really well for awhile but eventually the stabilitrak and traction lights came on. Only checked the positive because that’s where the mega fuse was. Haven’t replaced yet.

    The negative cable is known to corrode from the inside out. I'd just change it for the sake of being thorough.

    Was any work done to the rig before this all started happening? Engine compartment or firewall and lower area? Like has been said, the cable connections can look good at the battery but the corrosion problem can be inside the insulation and if bad enough the cable insulation will be swollen. I personally would check all wire connections under the hood and all over the engine and look to see if any wire is rubbed thru or loose connection. You said before that the wire was grounded out but they did not tell you which one? Repair bill say which one? Why would they not tell you which wire?

    It’s possible they told me which wire, but it’s been a year. I will def take care if that ad well. It’s possible they made up some shit just to charge me $145, but honestly I was expecting way worse.

    Was that the last work done on the Tahoe besides normal oil change or anything like that?
