2025 Grenadier Smoking while Idling

[MagicShrooms]

2025 Grenadier with about 2700 miles. No issues to date except for today when idling in car pool line with engine running I noticed an excessive amount of smoke coming from under the car. Couldn’t tell if it was coming from exhaust or somewhere else underneath. Turned the car off and it stopped, moved it to side of road and let it sit for a couple minutes and no more smoke.

Drove it about 20 minutes back home and no issues.

No lights or warnings or anything like that. Engine temperature normal. Looked underneath, under the hood and on the ground with no visible leaks. Using 87 octane fuel.

Do y’all have any ideas? I didn’t see any similar issues posted on the forum.

well last time I had white smoke that went away after some time it was due to a turbo leak, but it was internal not external leak. I had it on a Ecoboost 3.5L. Not saying that is it but check oil level often. Keep eye on it or if you are close take it in see if then can find it.

Thanks @Tenac we just drove 2 hours this afternoon with no issues but I’ll monitor it. Thanks again for your response!

Most likely a plastic bag or road debris melted on your hot exhaust. It burned off once and is gone, which is why you see no leaks and it drives fine. Very common on new vehicles. Just keep an eye on it.

87 octane?

Curious on this too. It says it can take 87, but prefers 91. I wonder what the computer does to the tune to prevent knocking.

May some protection grease for transporting the car from Europe to elsewhere via ship. You may have finally reached an engine, differental, exhaust etc temperature for a longer period thus the grease o protection film is evaporating.

Check for oil leak at the valve cover?

First major mechanical breakdown

Makes a lot of sense. My son also spotted a dead squirrel in the car pool line. Wonder if that poor thing somehow got stuck in there and umm expired.

Yes, I didn’t see any fluids at all. I looked pretty thoroughly today when I dropped the windshield wiper fluid down into no man’s land of the engine compartment.

Yep that’s what I’ve been using, I am step it up to the mid grade and see if I notice any difference.

Great point! No issues since so I’m thinking it was a one off. Drove through a bunch of unpaved mountain roads today and performed excellent.

That is a scary thought - I really don't think we should introduce our Grenadiers to bad habits.

My block paving still hasn't recovered from 20 years of Land Rovers marking their territory.
