Came home with a few items, and the turbo temperature was 525 degrees, so I left it running (with garage door open) while I brought my purchases into the house. Fast forward 2.5 hours and my wife discovers the still idling Jeep on her way out to run errands. Ouch...Senior moment. Any repercussions? Should I change the oil due to possible contaminants?

Other than confirming my knucklehead status, any other thoughts?

I wouldn’t be concerned unless you think it overheated. Diesel idle forever, that’s why Cummins started putting them in fire trucks way back in the day.

I'd guess it's probably fine, just don't do it again ;)

Coolant temperature was just below the middle line and turbo temperature was 278°. So, seemly nice and cool (so to speak).

Ambient temperature was 91° - summer has finally started here. Love the heat.

I thought there was a built in timer that shut the engine off for these kind of situations.
But other than wasting fuel, I don't think you did any damage.
Since you have Scanguage, and if you did not see any codes pop up, you should be fine.

My Ram will only timer shutoff if I use remote start. You can restart it remotely a second time but after that you have to get in.

We lost power a while back and I let it idle in the garage the entire day with an extension cord going to my laptop (work from home). I decided I wouldn’t do it a second day because they aren’t filling my tank and everyone else in the area just shut down for the day.

All vehicles with push button ignitions should have this auto shut off IMO. It is very easy to forget turning off.
Happened to me in a gas station once. After I finished fueling and got back into the Jeep, I realized the engine was running and i forgot to turn it off. It was a 2.0L and it was a very silent engine.

This should come standard on all modern vehicles IMO.

I’d be good with the auto park feature if it used a pressure sensors in the seat. I find it irritating when I’m trying to move the Jeep a few feet with the seatbelt off and the door open (looking where I’m going) and it abruptly goes into park.

tbh I kind off miss the days of having to manually turn you headlights on and off. I get the safety considerations - I actually turn my lights fully on every time I go somewhere. But I feel like the whole”pre-flight/post-flight” checks that we used to have to do helped wire the brain to be more observant.

Zero issues. In the far north they let their diesels idle all night so they don't freeze up.

Idle forever is pre 2007 mentality. What can happen on the modern diesels is the engine and exhaust temperature drops below normal operating, creating excess particulates for the egr and emissions to process.

Modern vehicles can idle for much longer than 2 hours with absolutely no issue. Big rigs with diesels sometimes spend all night idling as the driver sleeps. Idling is not an issue so long as engine temperature is kept at operating temperatures, which shouldn’t be an issue with Jeep’s powerful cooling fan. 😁

Please call them and tell them to stop idling their new 2020 Diesel pickups all night when -40C. Tell me what they tell you to do.
