Serpentine belt at 13k miles?

So driving to take one of my buyers for holiday lunch yesterday and I hear this RPM dependent non-metallic rubbing noise. Thought maybe it was a shroud or something like that but it ended up being only related to RPM not speed. Turns out the rear rib of the serpentine belt is half gone and there is a small piece sticking out just running around whacking things as the engine spins. So I went and grabbed a serpentine belt this morning but seriously are these things common to go that early? Only thing I can think is maybe since my car is an 11 and only had 11kmiles on it when I bought it last month there was some sitting that damaged the belt?

Oh yeah, I have the Phoenix v6 in this without EPS.

That seems early for a belt failure. With the belt off check to make sure all pullies are turning smoothly and easily with no squeaks. If you can, use a straight edge to make sure the pullies are all in alignment. Eyeball it if you can't get a straight edge in there. With it ripping one edge like that there may be a pulley alignment issue.

Doesn't appear to be common. I've read here of a couple, one vehicle kept throwing them. Probably a defective belt, otherwise I would also suspect pulley alignment.

You have to find what caused the failure, those driving belts are rated to last 120k miles.

Well took a few with the holiday and all but I did start to get a whine pretty bad in the cold. Pulled the belt again when that started to show up. The idle (which has been revised including new bolt from Chrysler) pulley has more wobble to it than I will accept, listened to it with a Stethoscope and there was definitely whine coming from that bearing. The pulley on the tensioner also shows more wobble than I want to accept as well. You can't get a Scope on the bearing in that pulley due to the layout of the tensioner.

So long story short both parts are ordered, I'm hope they are here before the weekend but that seems in likely. When I do the install I will do the idler alone first and see if the whine is still there before doing the tensioner to give some feedback on high it was coming from the most.

They really claim 120k on a seep belt now, wow. I usually do them every 50-75k on my cars.

160,000 on original serpentine belt on our 4.7 V8 Jeep..... Still looks like new ..... No cracks in the valleys ...... Early failure is alignment tensioner issue usually .

If you have a EPDM belt then yes 100k-120k is about the life span and they don't show wear like the older poly belts you have the measure the rib depth.The older poly belts are the ones that rarely make it past 50k without being all cracked.

After futrrther testing it is the ac compresor tht is squealing. When the clutch is inactive the thing when's like a schoolgirl. Trying to find a clutch kit for this compressor, looks like Chrysler sells one for a hundred bucks not too bad if it really fits the issues. Would like to avoid dumping the refrigerant as tht just jump the cot thrgh the roof on the repair nd I can't do it myself.

Yeah it happens, no flame suit for you I'm too lazy to check them or care about the grammar, spelling or continuity in a post. Not going to deny it, can I blame the fact that I type most posts on my ipad or phone?

Well, the good part is you know what the problem is. No way the serp belt should be failing as quick as yours did, unless there is an underlying problem.
