with 12k miles, cvt problem should be covered under basic 36k warranty,
have you taken it in?
diagnosis?
warranty status?
before going corporate, should go through dealer,
as much as i dont like dealers, they are your first step,
and if have a problem with dealer then should try going corporate,
no point in bypassing dealer and going straight to corporate.

 

The whining could be the Alternator AOD pulley, or the PTU unit as well. It may not necessarily be the CVT. As evidenced by the members on this forum, CVT failure is very very low. Now there have been reports of bad CVT fluid thermostats on 2010 and newer models (some late 2009 as well) which allows the fluid to overheat and foam. We haven't really gotten good confirmation on these being repaired though.

Also, they are likely replacing the CVT with a traditional automatic simply because they got a better deal from the one supplier over the other.

 

problem is definitely the CVT; there's a 15 page thread about this JF011E CVT on Nissan boards and copious threads about whining, overheating, and the like; so much so that you could write a book about it!

The whine comes from the failure of the Koho bearings on the transfer gear as a result of a lack of lubrication. The noise gets louder until the debris from the bearings fills the filter reducing the fluid pressure producing a P700 or P777 code giving you limp mode.

Until then, it will whine, it will redline easily, frequently, and stay red lined like the gearing is off, and gas mileage will suffer. Nissan at least extended the powertrain warranty to 200k on some make/models affected. And safe to assume that since Chrysler moved away from this model in 2014, they weren't digging the complaints and warranty work.

My 2011 is at the dealer now at only 36k miles. I'm hoping they don't try to get me to kick the can because this sheet is ridiculous enough at 36k. Maybe there was a revision to the CVT, I HOPE!

 

I get the high RPM's now if I drive for a while on the highway. The dealer hasn't been able to replicate it. My RPM's skyrocket as I shift from Drive to Park. It was real bad a few weeks ago after a long trip, and my RPM's were high no matter what I did (until a few days went by).

I got the PCM flashed, and it hasn't happened anymore, although I think it slightly jumped once. Dealer can't replicate it like I said and it's too hard for me to make it happen on command.

 

Disappointed

I was driving my 09 Patriot and the truck would only go 45 miles per hour, RPM hand went up between the five and six, and making a whining sound. Has anyone had this issue and what was done to correct it..

I had the same problem with my 07 Patriot 109K miles on it, importantly it happened the same day I purchased it and was driving it home (3hrs drive highway), you can imagine how disappointed I was. Also at that point i didn't know that i was common problem with patriot, I parked the car for 1/2 hr let the engine cool, and drive back home normally, I check the reviews and thought it was CVT problem, took to mechanic and changed CVT fluid, which was burnt. Now, with recently filled CVT I am hesitate to drive it long highway, even car dives normal. I really want to visit yellowstone which is 8hrs drive but I am confused if i should take my patriot or rent another car???? LOL
Any suggestions??

 

CVT overheats (2014)

This continues to be an issue for the Patriot. I have a 2104 patriot with 16,000 miles and have had this issue on 3 separate trips. Same symptoms as others. Temp light comes on, speed drops, tach increases, and transmission screams. It happens after 3-5 hours of freeway driving. I have brought this to the dealer all three times. They look at it for 1/2 hour, run diagnostics, find no fault codes, and tell me there is nothing they can do. I opened a case with Chrysler after the 2nd dealer told me there was no problem and that Chrysler would allow them to expend anymore resources diagnosing a problem that didn't expect to reproduce. Each service manager makes up some explanation which is a mix of bad assumptions and pure fiction. I am getting a little tired of being treated like an idiot simply because they can not spend the time to find the root cause of the problem. The case manager scheduled the local dealer to have a recorder installed in the vehicle. Dropped it off in the morning as asked, verifying the expected installation. When I picked the suv up at the end of the day, the service manager once again told me they ran diagnostics and found no problem and when asked about the installation of the recorder, he said that the dealership doesn't have one, and since the computers record everything, he didn't understand why Chrysler would order one. 'You killing me Smalls" I'll keep pressing this and will not let the case close until it is resolved. I would like to regain my confidence that I can take this vehicle on road trips and get where I'm going without delays to let the tranny cool.

 

You can now file for Lemon since three times they weren't able to fix the same problem. Based on the previous comments from other members, your CVT fluid is now toast. Until you replace the fluid and change CVT filter and gasket, maybe even a transmission thermostat, you're going to continue experiense the same problem.

 

There is a video that I saw, maybe here or possibly YouTube, that has the sound of the classic Patriot CVT whine that precedes a problem. My O8 was making that exact noise. Took it to dealer to have the trans checked, problem was alternator! So both sounds are apparently similar or the same.

Just my two cents.

 

By and large, not an alternator problem, but transmission overheating problem. If you had alternator problem, likely constant and not related to terrain, heat, or duration of travel like the CVT issue. Jeep should retrofit all models affected w/ a transmission cooler; would probably save them a pretty penny on replacing CVT kits.

 

I posted a video of mine making the sound in August while i was going up the mountains in WV

https://www.youtube.com/watch?v=-STuUH2mmEo&list=UU_wkSoMQa_bo7nipoJemf-w

 

chris, that is EXACTLY the sound! And it was my alternator not the tranny.

Odd, very odd.

 

Hey,

My 2010 Jeep Patriot Sport turned over 100,000 and started to make a whine noise under load but not at idle. I have a video of my Jeep noise any idea what it could be. Jeep has no engine/transmission light on. The post won't let me post the link. Could text or email it .

 

Weird I know for me the sound triggers when i hit the gas hard when the car has been running for a while especially on hills. From the post I made on here about it everyone was saying it was the CVT. I have also browsed youtube a bit and it seems other cars like nissans w/ a cvt make the same noise.

 

many models have JF011E.

there's a good one of a 2012 Jeep Compass on youtube. Dodge Calibers too, same CVT - same problem.

Nissan even (partly) addressing issues on a macro scale here:

Still no fix for the CVT overheat problem?

Perhaps I'm not reading far enough into the multiple threads on this issue, but I have seen a lot of complaints but few fixes.

Flush, replacement filter and refill did not help my 2012. It overheated 4 times last summer. The first overheating was the summer after I purchased it, August 2012, with less than 20k on it!

I spoke with a reputable dealer rep today and learned that they are aware of the problem. Their fix is to install a larger transmission cooler, flush, replace the filter and fill the transmission. If necessary they replace the transmission as well.

The Mopar parts manual also shows two transmission fluid bypass valves (thermostats). One is the square box like one with four inlet/outlets on the driver's side of the radiator. The second is a round one, also with four inlet/outlets located on the transmission itself. My dealer rep wasn't aware of the transmission mounted valve.

Here we go agian. My wife just called me on the side of the road same exact exit she gets off at when the CVT in the Patriot overheats. Every summer. Starts with the chattering, then the whining screaming followed by the light coming on and shes going 55 in a 75... I need more details like a TSB # or something if this is true. Im going straight to the service manager, after a call to Chrysler.

 

This happened to me yesterday when driving up North to Flagstaff.
I had to pull over in Black Canyon City after a 45 minute drive to let it cool down.

I stopped at a shop and the mechanic who was working on a Wrangler had a smirk on his face when explaining my options,
option #1: get rid of the POS ... option #2: instal a transmission cooler. He did advice me to let cool down and that I would be fine.

This is the second time someone has laugh at our Patriot. The first time was 2 weeks ago when I got stuck on soft sand,
the tow truck driver had a smirk and said that the Patriot was no better than his Honda LOL.

Yesterdays temp in Phx reached 96, hottest day of the year thus far and it's only going to get hotter.
Summers here avg 105 with heat waves that make it even hotter, 2 years ago we experienced 118 for a day.

I am now looking into installing a transmission cooler.
Any tips or advice on where to go get one installed?

 

We already have a transmission cooler.
Pre-2010 or 2009 it was an external cooler, after it became an internal, integrated one.

Climb under and you can see the lines going from the transmission to the radiator.

Now I'm no expert at all, this was a product of my oil cooler install research and my friend, the auto tech, showing me things as we were under there...so take this as what it is.

But there is a factory cooler in the CVT Patriots.

Now...is your coolant up to snuff and/or are the various thermostats working properly to circulate coolant to the transmission? Checking the coolant is easy, getting the operation of the trans cooler thermostats checked out properly might take a bit if digging and pushing.

 

This issue has been going on since the car had 600 miles. Its common enough and has nothing to do with maintenance. Its an assembly issue, batch of bad parts, or deseign flaw that doesnt effect every patriot out there. Btw mine has only 16000 miles and Unfortuneatly its getting worse. I have an old thread asking about this issue, one of the repliers to my thread eventually got rid of his patriot and he described the progression of this problem in detail.
Is anyone aware of a TSB or has any proof that Chrysler is accepting this? It would be of value since it is impossible to get the dealer to reproduce, or even listen.

 

After a lengthy call to Chrysler Ive opnened a case, but the vehicle needs to be at a dealership for them to move forward. She said there is no TSBs or customer satisfaction complaints regarding this issue. This exact complaint is all over the net so I find it hard to belive this isnt a documented issue but who knows what the 1st step phone call reps actually have access too. As expected the rep was overly helpful and a good listener. doesnt fix my issues tho.

 

I had a very similar problem, my car would go from being fine to instantly high rpms and virtually no hp, no torque, just rpms and alot of nothing else. I took into a trans shop and it was a bad sensor.

 

Which sensor did they replace? I had the same problem with the whining , high rpm, loss of power and finally didn't move. I had to pull over for an at least an hour then I was able to drive until it did the same thing several times until I made it home. My 2009 Patriot has 69k and the dealer insisted that the trans fluid, filter and gasket needed to be replaced. I let them do the service and I'll be going on a road trip in 2 weeks. I have a feeling it's going to happen again.

 

Does the vehicle have any stored codes present? Having a stored code or being able to do duplicate the concern for your dealer is ideal. I’d be happy to look into this further for you. Please private message me your VIN and dealership if you’d like my assistance.

 

summer is here-my 70/70 rule!!!! ***important*****

I bought my patriot brand new with 57 miles.
It has now been 4 1/2 Years with 85,000 miles.

There is one golden rule to these things.

If the ambient air (outside) temperature is at 70*
Do not drive 70 mph. The cvtfluid will begin to foam
You will hear the wine and the light will come on.

Other than passing or extreme cold air like 20*or below
I won't ever drive over 73.

Save yourself the hassle. The dealers and Chrysler won't do anything about it.
I've tried. Thousands have tried.
The plus is....going an avg speed of 68 as opposed to pushing 75when if I can; saves me 4 mpg

Have you replaced your CVT fluid yet? I bet that will solve your issue.

 

Running fresh CVT fluid/filter and installing the Engine Oil Cooler seems to help. I used to have a bad whine on warm days but it's not as much of a problem anymore.

 

Did you do your own CVT fluid/filter?

If so I'd love a walk through of how...PM me if you don't want to clutter up the thread. I've developed a slight vibration and a bit of a moan at certain RPMs.
Still tracking to figure what the moan is but the vibration seems to be trans.

 

Since I was at 58K and still under warranty, I had the dealer do it. I bought my own filter, gasket, and fluid and they just charged me for labor.

I hope it's just something simple, these CVT's seem to be picky about having fresh fluid.

I bought Valvoline CVT fluid last time. Next fluid change, I might try Amsoil CVT fluid. Still cheaper than Mopar!!!

 

Tansaxle noise/ cvt call it standard front wheel drive?

I only noticed the whine when in a speed between 60 -100 km per hour driving my standard 5 speed jeep compass 2007 with 130,500km on it!
Note that while at the speed 60-100km per hr I depress the clutch and noise is gone let clutch out and same whine is back? This is definitely not the Alternator? as was mentioned in other cases: Nor did they say whether their jeep was a standard or Automatic?

 

Wife called yesterday afternoon and said her 07 had no power and a light on the dash was on (trans temp)

She was headed up the mountains to a writing retreat, made it about an hour out of Denver without any issues.

She was able to get to an off ramp and let it cool down. Made the rest of the 20 min drive with 2 or 3 cool down stops.

We've just got it a few months ago with 135k and I'm going to guess its original CVT fluid.


From what I've read we need to start with a fluid change and maybe add a bigger aux cooler.

The cooler bypass valve, I've read that can stick- is it worth it trying to clean it or is it better to replace?


Its sounds like getting the filter and fluid and having a dealer replace it is a good option.
Should I ask a place that does work on Nissans to quote the job?


Thanks,
-Charles

 

I think you're on the right track with the fluid and filter change. Having a Nissan dealer quote the job is good too. I don't think the '07's had the transmission thermostat valve. The other thing I would do is take it to a car wash or use a power washer to clean the cooler core out. With that many miles it could have a lot of dirt and debris clogging the cooling fins.

 

Thanks.

on these the trans oil cooler is built into the AC condenser? So running AC dumps heat into the transmission fluid?

I would that alone would be reason enough to mount an additional aux cooler.
