As a follow-up I just spoke to my service rep; he says they found a loose heat shield that was rubbing on the CV axle on the right-hand side, and once they fixed that the noise went away. I have my doubts as to it being something that simple (why would it only do that at crawl speeds, but not at other times?), but it should be fairly easy to duplicate the conditions when I've heard the sound in their parking lot before I take it home later today.

Also as an FYI on the rain leak, they've supposedly ordered new weather stripping for both front doors, so I'll have to take it back to have those replaced when they arrive (back-ordered, I guess they're in high demand!). They replaced a door weather strip the last time around, though I thought/assumed it was the back door on the driver's side...so we'll see what happens. I do know after driving a 2010 Liberty for the past week that I really miss my Patriot!

My wifes Pat with the CVT recently started making a grinding/rubbing noise as well, but only at speed. It drives fine, but there is a high pitched whine that was not there before. Loose guarde, or something internal? Anyone have any ideas? It's an 07 with 25000 miles.

Different noise attributed to CVT

My 2008 Patriot started making this whirring noise after having about 20K miles. The whirring accelerated with driving speed almost disappearing at low speeds. Went to the dealer and they said my transmission "had gone crazy." Dealer ordered a new transmission. They are installing it on Tuesday. We'll see.

Smile New tranny solves problem

Got about 600 miles on the new tranny and the noise is gone. The Jeep folks in Fayetteville NC claimed never to have seen a tranny problem before.

I probably have the same issue, the grinding noise at crawl speeds. I had the dealer check it and said it was the gas pedal making the nosie and it had salt in it or something. The noise did go away but came back in about a weeks time. I really need to get this resolved before the warranty is over.

Hey you described it exactly. I was experiencing the same thing. It almost sounds like a wheel in the cvt grinding as it adjusts itself. I took mine in and had to ride with the tech to show him the sound. He was able to make the 08 Patriot Limited 4x4 do it over and over. They called later and said it was the doughnut gasket on the exhaust. We will see if this fixes it.

My '08 has this same problem; I took it to a dealer (not the one I bought it from, since they're no longer in business ), and they kept it for a week (while they were also supposed to work on fixing my roof leak again, and change my oil w/materials I supplied). They claimed they tightened a heat shield that fixed the noise at crawl speeds, but it's still there. I was verbally told they ordered the seals to fix the leak, and would call me when they came in, but after a few weeks I went back to my paperwork to see how long it'd been, and on the official paperwork they say they were unable to find a leak, and there was no problem! Then to top it off, when I picked it up they tried to charge me something like $30 for an oil change, when I provided them synthetic oil and a filter!! They credited me for the oil change materials, but there should have also been a 1/2-quart of oil left over that I never saw (and now I'm wondering if they just dumped the full 5 quarts in there!!).

I was miffed at first, primarily because I'd a fair amount of money on a rental car (they kept my Pat for like 8 days), and basically all they did was change the oil (which I typically do myself anyway). I'm almost at 36,000 miles, which was the reason I took it in to have these things addressed before the main warrant expired, but I finally decided that A) the power train has a lifetime warranty, so if the problem becomes a costly issue I have a record of bringing it to their attention early on, and B) if the leak continues to be an issue, I can probably get it taken care of myself cheaper than I can rent a car for a week, and C) I will NEVER do business with this dealership again. During the time they had my vehicle I'm not sure they ever called me; I was always having to call them every couple of days to see what the status was, since I kept having to extend the rental car contract every couple of days.

Anyway, sorry for the rant, but just bummed that the dealer I bought my Jeep from was only a few blocks away from my office, which was one of the reasons I bought it...now I have to drive 15+ miles to another town to get any work done, which becomes a major scheduling problem.

I'm also discouraged because of the huge variety of diagnoses that are given for this problem; as common as it seems to be there ought to be a confirmed cause/repair sorted out by now. At this point I'm just going to treat the noise as "normal" since it seems to be so prevalent, and be sure to take mine in for it's 5-year checkup to keep my lifetime warranty up to date, so if it does become an issue that requires repair it'll be covered.

I had the same thing!

Hey Guys,

My '09 Pat North Ed. had the same noise that appear around the 10k km mark. Did the same thing...went to the dealer and got the "we don't hear anything unusal" line. After taking the service mgr out, then I got the "how did you hear that!?" question. They kept it for another day only to be told that this was a normal "selenoid" sound. Funny?? I never heard this before! Anyway...if you look back through the threads here on JP.com...you'll see that many of us have been is this situation before. After three unsuccessful trips to the dealership, I finally went to another Jeep dealership who immediately stated that this sound was not normal. They said they needed to keep it and they would let me know ASAP. Ninety minutes later, I got a call stating that a new tranny has been ordered. I had my Pat back by noon the next day! Although they could not give me a concrete reason for the noise, their own research with the component manufacturer revealed there are some bad bearing systems out there. The mfr gets the tranny back and does their own autopsy. Ever since the new tranny went in, that low speed scraping noise is gone! If you continue to get the run around, try another dealer. It solved my issue right away...and I have a new service dept now! Hope this helps. I found the information gained through the members on this site gave me the knowledge and "ammo" to go in and state facts...yup...made them listen!

I have a 2009 Jeep Patriot with just 16,000 kms...I bought brand new in Sept. 2008. I started having this grinding/rattling noise as well when driving at slow speeds. I took it in to the dealership...they told me they too could hear it. When they called me to come back in and pick it up they said I needed to bring it back in when the foreman was in. So, I did. They then told me the noise had to get worse before they could figure it out. The noise got worse so I brought it back in. The foreman apparently took my car home over night and said he couldn't hear the noise. The minute I got in the car the noise was there. I then took it in to a different dealership...they told me the noise is a characteristic of the CVT transmission and that they couldn't do anything about it. The noise has gotten louder and now my car almost stalls out when idling (at a red light or waiting in a parking lot). I took the vehicle back in AGAIN. They again told me that the noise was normal and that it didn't stall out for them. I feel like I have gotten the run around from both these dealerships and now have sent in a letter to Chrysler Canada just this past Friday. Hopefully they will offer me some assistance, especially now reading that several other people are having the same problems.

Maybe we should make a list of dealerships that are *aware* that there is a problem so we know who we can go to.

Grimsby CDJ Ontario

The CDJ dealership is the one that delt with my tranny noise quickly and efficiently. Not sure where you are from, but if you are anywhere in the GTA Niagara area...might be worth the drive??

The GAS PEDAL? Are you for real? They told you the GAS PEDAL? The pedal is electronic.
