Hmmmm back in 2022, and now this problem has come to light again. It happened today. Mileage went “- - - - - -“ all random warning lights and problems. Still definitely feel it’s an electrical problem, maybe it’s time for another new battery 🤔.

 

I checked the battery, its pretty loose in the compartment its in, but I don't recall it ever being strapped in since its been “fixed.” The ground is still pretty tight, and so is the positive.

 

Im so curious if I have been the only person to ever experience this problem with 17’ edge sport. Surely I cant be. 🤯. The battery location is poorly placed.

 

Im super surprised how well my transmission has handled such harsh shifts back to 1st/neutral due to the electrical malfunction. It’s got to be harsh as hell on the car cause it feels harsh as hell.

Did you you ever resolve the issue when it came back? Curious because I'm having your same initial symptoms? Was it another issue with the ground?

So ironically I did nothing other than kinda wiggle the ground a bit (it didnt really move I was just checking mostly if it was loose), and it has NOT returned… I entirely under the assumption that its a ground issue on the battery. I think the engine shakes just right and knocks the ground out for a minute. My ground wire has been tight against the brake fluid canister for years now.
