Valve body replacement

MSUGOGRN4781 said:
Another update. Apparently I need a new valve body. They are ordering it but not sure how long it will take. I will report back if it worked once they replace it.

FYI, update to my Murano. I too had the issue and just had the valve body replaced. In the five days driving since the repair, I have done everything to try to re-create the issue. And I no longer have the issue of 15-20 mph shimmer.

What I have found is that the engine no longer seems to have shift points, which was New on the 2015 and a possible cause of the issue.

end result, the SUV seems to run smoother and feels more solid.

Have you had the valve body replaced? What are you thoughts ?

'15 Murano SL...build date March-2015 with 9600 miles.


Unfortunately I can be added to the list having this issue. I waiting posting this until I had further info.


I noticed first about a month ago. Of course I've been reading this thread for months prior hoping it wouldn't be a problem for me. Same as most have described here. 18-22 MPH shimmy/bucking when lightly pressing the pedal---kind of like going over rumble strips. I took it in and was able to duplicate with the service advisor and made sure he noted that he did see and experience the issue. Mechanic drove it home but couldn't duplicate himself. The applied a previously issued software recall change/update initially for the Altima a couple of years back. For the next couple of weeks it seemed to resolve it.


But over this past weekend it started back up again. I took in but for whatever reason could not duplicate the problem with the actual Nissan tech in the car (not the advisor this time). Regardless they gave me a loaner and the tech kept my car and drove it home overnight. He connected his computer to the car and was able to duplicate the problem and capture the data needed to submit to Nissan.


They will be either replacing the valve body and/or the transmission. I'm ecstatic over that. :rolleyes: I'm mean of course I'm glad they have been able to duplicate the problem and a repair will be made. Just not happy the car will have to be torn down to the level needed to replace those parts. Just so much room for "things" not getting put back together correctly. Hopefully they will be ordering part(s) today and have them come in tomorrow.


I have no complaints with my advisor or the dealership at this point. I've been diligent about the details and documentation and my advisor has been patient and open to addressing my needs. Not just with this but the previous 3 recalls (unrelated to the tranny).


As far as the adaptive learning and the ECM learning ones driving style. I get that and understand it. However, one should not have to change there driving style or habits. This problem should not exist based simply on driving habits and having to dis connect battery and "reset" it. It's a physical/mechanical failure, that no software will fix.

Good thing you have plenty of time (apparently) to be documenting Nissan's problems for them. I will dump this car before I spend vacation days doing their job for them. I'm really hoping we can avoid this, but I've felt it once with less than 1000 miles and expect problems.

I'm thinking the vast majority of these cars have the problem and that replacement parts won't fix it permanently. It's a combination of poor engineering and poor QC apparently.

Robo....not so much I have the time as is it the variables. I'm self employed and my office is only 4 miles away from the dealership. I can also have one of my guys pick me up and/or take me when ready to pick up. But yes, if I commuted or whatever I wouldn't be so understanding or forgiving as it relates to "time" and hassle. Now the situation as a whole I'm not happy about at all.


Chucker, the most common sequence seems to be from a slow roll as if you were in slow moving traffic. Anywhere from 17-22MPH seems to be the sweet spot. I think the important second piece is the rpm's need to be at 1000. So find a safe place to do this....just kind of coast at 20mph at 1000 rpm and lightly press the gas. Again as if you were in slow traffic and not necessarily looking to actually speed off. If you have the problem, eventually you'll start to feel the car slowly vibrate and "chuck". For me, once it starts if you do nothing else with the pedal it will increasingly get worse and the whole car will start bucking and jerking. To the point , instinctively you want to let off the gas. Which I do of course let off. Don't want to cause damage.


The dealer did call, they replacing the valve body. So we'll see what happens. My wife loves the car, outside of this I have no other issue with the CVT. At speed it shifts smooth and for a heavy car with only a 3.5L it has pretty good pickup.


SInce I have 4 more years on the drive train warranty I will play the waiting game. However, I will of course monitor it closely and this and other forums to see how this plays out in the long run. Trading it in is a strong possibility however.

Same here on the trade. First Nissan, and possibly very quickly the last. For the money the QC is horrible. Reminds me of American made Hondas. They're horrible, too.

That said, people tend to love them. I just hope the resale stays up.

Valve body, transmission... I wouldnt be happy, but that's nothing like the full engine replacement that the dealer did on my '04 S4 when it swallowed a valve. Sat on the lot next to train tracks for a month. Talk about a major operation and detailing job after!

My point is it's not fun and I wouldn't be happy, but I wouldn't be to the point of selling the car. I had a 03 Loaded Murano that I kept for over 11 years, and was very low cost to maintain.

Just a point to consider, are all of these CVT issues with "early" built Muranos, ie: 2015?
Let us know.

Robo/Jester......we really like the car. But as I mentioned due to having 2 years of B to B and 4 years drive train left on the warranty I'll have time to monitor this closely. It will also allow me to see how the 17's and 18's play out. I have no burning desire to go thru the car buying process again. So....to show my age (although I barely remember this TV series).....as Master Po would say to Caine....have patience grasshopper.


Anyway, jokes aside. The valve body came in today and they were actually able to get the work done as well. I'll pick it up tomorrow. I'll report back as needed. I'm also going to try and find out the OBD codes.
 
#130 ·
Hey FreeFall, to split a hair OBD is On-board Diagnostic. As in the OBD presented a code of Pxxx. You can connect a scanner to the diagnostic connector of the car and it reads the OBD of the car to get codes and different information.


Anyway I'm glad the reprogram worked out for ya. I can't say it presented any better performance for me but it did seem to either "fix" the issue or hide it for a short period of time.


I picked the car up but have only been able to drive it for a few miles, you know work and all.


Rest assured I will be over the long 3 day weekend.

I'm very familiar with the OBD system. What I'm saying is that the reprogram was for more than diagnostics. Easy way for them to try to correct a known problem without acknowledging that a problem exists. I'm pretty well tuned in to how my car performs and it is definitely different. Put about 200 miles on it since the reprogram. It's not just that little surge being gone everything about acceleration is better.

Gotcha....Any reference to "reprogramming" I've seen up to this point was with the ECM or anything other than just the OBD. Not necessarily the OBD itself. I'm not sure how "reprogramming" the OBD would affect how the transmission shifted. I would have assumed any update to the OBD would have been more related to how it received and/or presented the captured data.


But hey, I didn't design it, so *shrug*.

Thought I would post my experience after 4k miles of driving.

This transmission is butter smooth and performs great. I am hyper vigilant about any noises or things- and here is what I notice.

1. The torque converter unlocks around 20 mph when you are slowing down and you lose engine braking. This causes a perception of moving forward while decelerating. Barely noticeable and most people wouldn't acknowledge it.

2. After a lot of highway driving, the car adjusts trans performance for maximum economy, and tries to keep in the lowest gear ratio possible. If you are at low speeds and going up hill, It might almost feel like the engine is lugging if you are barely touching the throttle. Pushing the throttle in a bit up hill gets the trans to move to a better ratio and accelerate.

Other than that, I really like it.

So I've started having similar issues to what others have stated. I have a 2015 Platinum with 15k miles and for the past week have noticed a shutter/jittery feeling at low speeds (15-25mph) when lightly accelerating. I'll be bringing it in for 15k service and will see what the dealer says, this is ridiculous for a 40k vehicle.

Noticed a lot of people commenting on this, I'm also seeing this and am taking my car in for routine maintenance this weekend. Will take what information I've found here and push for a fix. I don't want this to become an issue down the road just when the warranty runs out. GRRRRRR!

I don't have this issue.. yet.. but please keep us updated.
I had a slight vibration when ideling under load, dealership was very helpful, they noticed that RPM dropped lower than expected they just had to bump it up and this took care of the issue.
It could be a placebo effect, but the care drive faster and has a quicker launch , the mpg was better but still need to test more, need to make them lower the idle little bit as the RPM is sitting right around 770 and previously the vibration starts when the RPM drops to 550

So just called my dealer and mentioned the "chugging" - he seemed to know all about it as he mentioned "I may have to order parts" - based on what I've read here, the extreme case is new transmission.

Taking the car in tomorrow AM.

I'll try and take a video of what's happening tonight so I can see the RPM as well, never thought to pay attention to that.

Car has 26k KM on it - couldn't find the build date... didn't look properly.

Guess what I'm upset about is if they know this is an issue, even if it's not impacting every Murano out there but they can narrow it down to specific build dates - why not have the owners come in and get their car looked at??? I know, I know, it comes down to money.

This has soured me a bit on Nissan, lets see how they take care of the issue.

Best of luck! and please if you find any details or technical bulletin they are using so others can reference the same fix to they dealer, looks like you are lucky with your dealership!

The car build date is in tag when you open the driver door, around the same area where the tire psi is listed.

Good luck and keep us posted!

Just at the dealership now. They will have to replace the transmission, but will be offering a 10-year warranty on it. Will be getting everything in writing.

It is disappointing, but the process was very well handled by the service tech (Emmanual) at Applewood Nissan in Richmond, BC Canada.

Asked the tech why wouldn't Nissan just recall the vehicles if they know this is a problem, his simple answer: money. Too expensive to recall especially if the issue is intermittent or not experienced by car owners, so it's really up to the owner to notice these things and then take it into the dealer to be looked at and repaired.

I get it, so am glad that when I explained the problem there was no push back by the dealership. They almost immediately said that they would need to replace the transmission.
