The exhaust is supposed to be stainless steel.

I've had issues getting the positive terminal fully mounted on to the battery so there's a loose connection there as well.

Sometimes I'll need to get out and toggle with the positive end of the battery terminal, but I haven't had to jump it.

Well, then what do you expect? Fix the battery terminal connection.

I'm attaching a photo of my exhaust.

No offense, but that looks terrible. A quality exhaust should never rust like that.

As far as disconnecting the aux negative cable, i have not done that-nor am I sure of how to do that

Then you didn't do the aux battery bypass properly. See the thread below:

In all honesty, take the vehicle to a qualified mechanic/repair shop or to a dealership and have them fix everything. Put the fuse for the aux battery back in place and have the aux and the main replaced. Remove your rock lights and have the exhaust replaced. Leave everything alone at that point, as it sounds like you are causing your own issues by not knowing what you are doing.

I have a 2 liter turbo engine. I've taken the fuse out for the aux battery. The stock battery has been replaced.

The jeep was shaking particularly in the area near the exhaust. It has only happened that one time yesterday

shaking in the rear?

Yours looks like it's been under water. Again, quality stainless steel does not rust like that. Look at the rest of the exhaust in your pic. And that is OEM.

In a nutshell, get rid of the crap items on your Jeep and go from there.

Someone has already suggested you check the battery terminals.

Suggest: If you don't have tools and don't wish to do the work, then take it to a good mechanic.

* battery terminals (old battery? terminal corrosion? loose connections?)
* belts on your engine (condition? age?)
* air filter (clogged?)
* oil change?
* probably more.....like motor mounts/transmission mounts/exhaust hangers

I was having an issue with my 2020 jl 2 door just a moment ago. Currently it's piping hot in Virginia and I'm about 6500 miles since my last oil change.

I tried to start up the jeep after it had been sitting out in the sun for a few hours and it was wobbling, specifically in the exhaust region. I have an aftermarket exhaust and it's gotten extremely rusty since I got it. I'm due for a new one. I tried to power through the issue but after hitting the gas, the car had no power. I turned the jeep off and back on again and it's seemingly working okay for now. I have rock lights attached to bolts on the battery, which sometimes make starting the jeep take multiple attempts, but I'm thinking these issues aren't related.

Sitting at 56000 miles in the JL wondering what the issue could be. Only maintenance I've done to the vehicle is a battery change, regular oil changes and tire rotations. Wondering where the issue could be.

The exhaust hanger issue could explain a rattle, but wouldn't explain why when I gave the jeep some gas, it moved with significantly less power than normal. I haven't had an issue since and I'll probably end up replacing the exhaust next.

The exhaust being rusted could have something to do with me driving the jeep in salt water occasionally in the summer. Haven't noticed rust anywhere else though.

Removing the rock lights would be a last resort option. I would imagine the issue has something to do with the auxiliary battery still being used and/or the main battery positive terminal missing an angled metal piece to tighten the hold of the terminal bolt.

Why? You clearly indicated that once they were installed you began having issues. It’s your vehicle, so do what you wish. Just note, you came here for help and a suggestion was given. So be it.

I would imagine the issue has something to do with the auxiliary battery still being used and/or the main battery positive terminal missing an angled metal piece to tighten the hold of the terminal bolt.

Don’t mean to come off rude here, but you clearly have no idea how the dual battery setup works on your vehicle. As such, you likely have caused more harm than good to the vehicle with anything that you’ve done to it. As suggested previously, put the fuse you pulled back in place and take the vehicle to a qualified mechanic or a dealership to have it repaired properly. I’m out at this point. Good luck.
