It's not uncommon for one of the pulleys in the belt drive to fail when exposed to water. Especially muddy water. I have had and know many others that have replaced the tensioner pulley for what you are describing. Almost sounds like a turbo whine. For me, it started as a very low whine theyn just kept getting worse.

Hopefully that's all it is for you. If so, you can pick up a pulley from an auto store for under $20 and install it yourself. I believe it was one or 2 bolts and you do need to remove the serpentine belt...at least off whatever pulley you need to replace. Took me about 10 minutes to swap out.

If its not a pulley, then I am not sure what it could be.

I have 2,700 miles on my Rubi and I went through deep muddy water around 1,800 miles. My serpentine belt went and they replaced 3 pulleys under warranty.

Mine did the same; I could hear it squeal at start up then it would go quiet until it totally froze up.

Just dropped mine off at the dealer an hour ago for the exact same thing. Went through a deep mud hole a little over a month ago, and immediatly got that whine. I tried the "ignore it and maybe it'll go away", but it's just gotten worse as time goes by. From what I've read, it's exactly what everyone said, the belt tensioner bearings going bad. Should(better) be covered under warranty. I'll try to post my results tomorrow after I hear from the dealer.

yea same here i got an apointment at the stealership early in the morning.Was talking to my old man about it he said if your gonna go plying in that crap he said lol put some wd40 on your pullies ect before you go never herd that one before...

It was the tensioner bearings. Unfortunately, it looks like I'll be paying for this one. Apparently it's not considered part of the powertrain and my bumper-to-bumper was over in May.

Mine were covered under warranty but I had to wait a week + until they came in. They were back ordered 'cause too many mud holes.

LOl thats so funny i just called the stealership were i live in gp alberta canada and the service rep said the same thing the iddler pulleys are on back order he said another jeep just came in for the same thing after me he said..He said must be a defect ....nothing was said on my behalf lol

My dealer has one coming in for me tomorrow. Maybe I should keep the service paperwork in case there's a recall down the line. Seems like there's a lot of this going on lately.

We get that all the time down here in the lowcountry... so, with the engine running, I hit the backsides of the pulleys with a garden hose for a few seconds. No more whine.
I think sand and dirt gets lodged in the bearings and the water jet dislodges it.
This works for me.
Good luck!
