Cummins HO Squeaky Belt or Pulley

Update 04 June. I went to arbitration due to 9 repairs and the truck needing a 10th it was determined that my truck is to be bought back by FCA. The mechanics and engineers of FCA were unable to determine the cause. I know others are having the same issue and recommend that you keep notes of everything that has occurred and demand thorough documentation should you bring it to a dealership for repair. Luckily I kept everything, organized time line of events, parts repaired / replaced and was able to articulate the effects have had on safety and value. Utilizing FCA Customer Retention was very difficult and disappointing. They put no limits on how long the process takes for ultimate resolution. The people seemed to be nice but their process is lacking at best. FCA has an arbitration process that is discussed in your manual and worked well in my situation. When arbitration is used the process CANNOT take longer than 40 days (in MD) from the time your file is submitted to the arbitration company. After the decision is made by the arbiter (if in favor of the customer) FCA has 30 days to comply with his / her decision. Recommendation to anyone considering arbitration do not get emotional, present facts, and be organized.

So brought my truck In for my clicking noise not the Cp4 another clicking noise and it wouldn't do it when there of course....I'm starting to think its temperature related. It's getting hot here in new England and the noise maybe gone away for summer... Anyone else experience this??
 
Went to dealer today to pick up a part and it happened to start making noise. I went inside and asked mechanic to come take a listen and he confirmed it's coming from belt area. Not sure what it is I made a appointment I might have to cancel if noise keeps going away and coming back might reschedule until it constantly make noise so I'm not wasting my time.

Anyone find exactly what ticking is? Don't want them throwing parts at it until fixed

My truck has been at the dealership for a week now over this issue, and what burns me the most is I dropped it off Monday night and figured this is a pretty straight forward issue. Start the truck in the morning when it's cold and stand in front of it, after running for about 20 seconds it starts to squeak for about 30 seconds then it goes away until you let the truck sit in the cold for another 8 hours. I explained this to the girl in service over the phone, and when I got there my truck was making a buzz/rattle noise I also wanted checked out.

So I asked the girl in service to come out and confirm yes, something is vibrating against the firewall. After she did that, we were about to walk inside and I reiterated about the squeak I hear on cold starts and said it sounds like a belt squeak but it seems more metal on metal like a bearing...

So Wednesday afternoon rolls around and I still haven't heard anything. I call up, I get a different girl, and ask what's going on. She says they have not been able to replicate any of my issues, and the tech has gone out and started the truck at least 20 times, and the only metal on metal noise they heard was the clunk you hear when you push the brake and it unlocks the shifter.

All I could think it's WTF? What are they even telling the tech the problem is if he thinks the shift release clunk is the metal on metal squeak I brought it in for. So I said I have a video, can I send it to you, she said oh yeah that'll help send it to my email. So I sent 2 videos and another explanation to just stand in front of the truck and remote start it and listen and you'll hear it.

Well it's now Sunday morning still haven't heard a damn thing. This is extremely frustrating my truck has been there for a week for such a simple issue.
 
The service writer IS THE MOST IMPORTANT PERSON AT A DEALERSHIP!!! A good one is like gold and about as hard to find as Unicorn $#!T.

Yea it's impossible to find a good one. I really feel like when you explain a problem to a service writer, instead of just typing what you say directly on to the ticket, they do something else. They take what you tell them, and then they think about it, interpret what they feel the problem is, then write on the ticket what they think the tech should check to rectify what they think the problem is... So frustrating.

I would be totally fine if she had said to me yes, they heard the squeak, but it goes away so quickly they're having a hard time determining the cause and have to keep checking it every morning to try and narrow it down.
 
Heck customers can walk through the shop in my small farming town dealer and talk to the mechanics! I just hope with the downturn here they can keep the couple crackerjack mechcanics and I did loose my ‘’golden’’ service writer. :(
 
Well, i called this morning to get an update, supposedly the tech did hear the noise, but it disappears so fast they're having a hard time tracking it down. Which is fair, i get it, it's such a small amount of time that it makes the noise, it's gotta be really difficult to track down. Unfortunately i need the truck back to take care of a few things like jockeying my Travel Trailer around to winterize it, so I told them I would pick it up today and bring it back when the weather gets colder and the noise possibly gets worse but then it'll be easier to troubleshoot. I have to go back sometime in December probably anyway to get the updated rear body mount so I guess i'll have it addressed then.
 
Well my suspicions were correct. I brought the truck in for 3 issues:

1. The squeak this this is based on, I told them specifically it sounds like a belt squeak but it has more of a metal on metal tone to it, like a complaining bearing
2. There's a vibration in the dashboard by the windshield, last time I had it looked at (a week after i bought the truck) tech said it was the trans dipstick vibrating against the firewall, and when i dropped it off I had the girl come out and listen to the noise.
3. Rear passenger body mount clunk (wasn't expecting that to get fixed, just to get on the list for the redesigned mount)

That's what i told her over the phone, and in person, here's what was written on the service ticket:

1. "Customer states Metal on Metal when starting car behind dash when in idle" < that is DIRECTLY copied off my service ticket, it's so incredibly wrong it's almost funny, and i completely understand why the tech couldn't figure it out.

2. "Customer states clunking noise when going over bumps"

Needless to say i requested to speak to the tech directly, and explained everything to him, and he apologized and said the writers do this kind of stuff all the time. Luckily i was able to replicate both noises for him right there on the spot so he told me to schedule another service appointment and he'll know right where to start looking for both issues this time around.

Man, I got a 2020 2500 with 4900 miles and started to develop a squeak from. What seems to be the belt/pulley area. Any updates on fixes? I made a NTHSB complaint.

Brought my truck back to the dealer for this issue a week ago, they called me Friday to say they've escalated my truck to their in house diesel mechanic and he'll be taking over Monday... I'll post back when I have an update.

Watching for updates as well. Mine started doing this same thing about 2 weeks ago (49xx miles)
It’s hard to get mine in the dealer and none of them have loaners so I was gonna just swap belt and tensioner but I wanna have this documented in case it turns out to be a bigger issue.
 
Mines doing the same 8000 miles been following this thread haven’t brought it to my dealers attention yet think Ill call this week to schedule appt.
 
Hey all. Just replaced my tensioner pulley with a gates one from NAPA. $110. The gate one is way beefier and feels more solid. Oh and did I mention the squeak and chirp is gone.

Ill be dammed if I’m going to replace a tensioner pulley and spend $110 The dealer can figure this out for $82,000
 
I mean I get it. But the factory ones feel cheesy compared to gates. It was a 30 min job. Not worth leaving your truck for half a day or more at the dealer only to have them put the same faulty one back on.
 
Hope this wont have any warranty issues down the road with a aftermarket item .
