Vibrating gas pedal

manual shift - no Vibration

Hi Marc: Nah, I don't generally let up, I leave my foot in it :D
Since the shifting is electronic with solenoids & such, I don't think it hurts it anything. I let the torque converter do what it was built to do:D
That motor is a torque monster anyhow, it is good in any gear !
It has to be a strong transmission. It shifts very smooth in drive. I don't see how the vibration could come from the transmission.

Its such a nice vehicle. I pumped up the tires a little bit on our trip this past weekend.
I have been experimenting with different air pressures to see which ride I like best. Right now I like the 38 front 41 rear. It seemed to stiffen up the side walls on the tires some. Less lean but not harsh. Now I have the stock 20" with the Bridgestone tires.
I will see how this goes.
How is your Magnaflow doing ?
Have a good one!

yeah im not worried about messing up anything. sometimes i just like to take my foot off when "changing" gears to fully mimic the manual transmission "feel".

just today parrot i was on the 170 (SOCAL) in a bit of traffic and I was manual shifting. i thought about you.. :D

the rev matching is awesome!!!!

but i attempted to "Feel" any vibration (i have 22s and HBMC) in manual and didnt feel anything. i may also experiment with different tire pressures. dont want to pre maturely wear the tread, but would love to hear you continued results with different tire pressure.

the magaflow is beautiful. no drone.

enjoy... :D
 
Has anyone got an idea on this issue? Seems we have been waiting long enough where is the fix?
 
nissan have said there is no fix. they dont even recognize it as an issue as per what has been posted here. thats the horses mouth, so either more people need to go to a shop and have it documented, or just wait and see when/if nissan will acknowledge.

How hard is the gas pedal vibration? It must be hard and violent to feel the pedal vibrate through your shoe. I have tested my wife's 2012 QX going thru the same situations as described here; accelerating from a stop, accelerating up through 3500 RPM when passing, even in the driveway in neutral accelerating up thru 4,00 rpm. Either my size 11 is too heavy to feel any vibration or there is not a problem. I even did the testing barefoot with a light touch to the accelerator pedal. A very interesting and curious phenomenon.

Size 11 shoe for a 4ft 2 midget?
 
mccins1... ignore what marctronixx said in his last post... he fails to understand what some of us have ACTUALLY persued and done on this matter (a re-read of some prior posts of mine and others might be helpful)... First, Infiniti acknowledges this IS a real ISSUE! I personally have heard that from the horses mouth (Infinity Consumer Affairs) multiple times! They actually call me at least once a month since I have a "Case File" with ICA, to let me know Infiniti is still working to identify a fix for this COMMON problem. The local Infiniti Dealers and Service Departments acknowledges this is a real issue I have ACTUALLY had a Regional Infiniti Service Expert" assigned by ICA to come from FL to SC to drive my QX 56, and he stated this is a VERY COMMON PROBLEM with the redesigned 2011 and 2012 QX 56's (his words), and that he probably cannot fix it. Took him about 10 seconds in the drive to say, "Yep, there it is, what I expected to feel" and for the next 30 minutes started and stopped continuously, worked on it afterwards for 4 hours with no success, and left town. There is NO FIX, there is NO TSB at this point, but this is a REAL issue, not conjecture. For someone to say "(nissan) don't even recognize it as an issue" is laughable, and totally misleading and incorrect.

Updated to add that mine is an AWD and I am now over 15k miles and still no vibration. I hope all of you guys with issues are rewarded with a resolution soon for your efforts. I know it's frustrating. I can promise you it is surreal for me because I have never been on this side of this kind of situation before in my life so I feel your pains. Happy to help in any way I can and like Marctronix if anyone lives near the metro Detroit, SE MI, No OH, NE IN areas has a Qx with any of these issues I would like to drive to experience it as well.
 
whats up with the disrespect?

just because a handful of folks feel they have this issue does not make it a recall situation. there are many of these cars on the road and many people,, myself included, do not have this issue. in my opinion (everyone has one), you should relax and ease up on disrespecting me or anyone else who chooses to go against the grain on this internet chat.

Now i am certain you cats maybe experiencing this and i am not trying to downplay it, but if nissan/infiniti says there is no fix, then what can you do about it? either drive the car or trade it in/sell it. crap or get off the pot! :D

I kid, but really i appreciate your passion in getting your issue resolved...

Has anyone demanded a new vehicle yet? These are $70,000 vehicles and we should not have to put up this issue. I have contacted Infiniti direct also and they do admit there is an issue I am getting to push for a replacement vehilce and will let you know how I make out. This is not acceptable be any standard.

How are you sure that a replacement will no have the same issue.
As I posted earlier I have a 2013 and I can feel the vibration between 2500 and 3500. It is there and I can feel it but maybe it's not that intense in the 2013. I do not find it that bothersome. I also do not have a reference to compare because I have not driven a 12 or a 11 with the problem.
My point is that the replacement is not a guarantee for anything. The solution has to be found in engineering.
 
No disrespect intended Martronixx. I appreciate your posts. Just wanted to post the real, clear facts which are the absolute truth for those on theis Forum whio have this issue. Infiniti definitely will NOT do anything if others, including Local Infiniti Dealers, do not work it through any avenue, including the Consumer Affairs Division, and be very demanding VOCAL about it!

mccins1 is dead on the point! Thank you mccins1! Everyone in Infiniti at all levels admits this is a real issue! And it is insulting for a vehicle of this price to have this issue! We who have this issue were technically sold a defective vehicle!

Just yesterday, I was in to schedule my 15,000 mile Service Interval. The Service Manager stated to me "guess what, I have already had 3 new 2013 QX's brought in by owners complaining of the SAME problem with the Gas Pedal vibration"!!! And, one of the Service Advisors actually went so far to ask me, "have you consider starting/joining a class-action lawsuit against Infiniti"? This actually came from the local Infiniti Dealer!

My strategy now (and yes, I am passionate of getting some resolution - I have worked on this for 10 months!) is to demand a replacement vehicle, new, same options, confirmed to NOT have this problem, for no added cost to me. If the Dealer refuses, I do have an Attorney ready to file suit for selling me a defective vehicle and not repairing the problem after 10 months of complaints. I have mountains of documentation to provide.

Thanks all.

Just out of curiosity, for the owners who have this problem, what are the size of your tires?
 
Just dropped my 2012 qx off for 10,000 service and the head tech was well aware of our vibration issue. He stated he thought it may be a torque converter issue and said he thought they may have replaced a few trying to solve the problem?

Unfortunate Vibration

I have a 2013 QX56 delivered Dec 20th. For the first several weeks and until I had 1800 miles, I did not have a vibration problem. But it started and seemly gets worse as the mileage piles up; 6000 now. As someone described it is as a vibrating cell phone and is prevalent from idle to about 30 to 40mph. I notice that it is more noticeable before the vehicle is fully warmed up.
I have complained to ICS and was referred to a dealer. The service manager was very accommodating and we drove a used 2011, (hardly any noticeable), a new 2013, (more noticeable than mine). He acknowledged they knew of nothing to be done until a Technical Bulletin is issued.
It's a shame, because the vehicle is excellent in other areas, but for the price it should be excellent all around. The sensation is annoying.
 
eWhite5... Exactly the common issue that many of us face. Unfortunately the local Infiniti Service Centers can't do anything about it. A Regional Service Specialist (see an eatrlier post of mine) was sent to assess mine, and could not fix the issue, and he blatantly admitted this issue is very common with the newly designed QX's (2011-2013)...

Any correspondence to Infiniti is circled right back through ICA every time. The last call I received after writing a certified letter to the "Main Infiniti Man" Mr. Ben Poore was referred directly back to ICA! That ICA rep advised me -I kid you not - to go to the Local Dealer and drive 3 of the new QX's to see if they had the same issue! To which I replied, "ok, and if they do, then Infiniti has a problem, and if they don't, Infiniti still has a problem in that mine has the issue"! Unbelievable.

There is no, and probably will be no, TSB on this vehicle DEFECT! I have been trying over 1 year now to get my problem fixed, to no avail. So, I have filed a serious BBB complaint against the local Infiniti Dealership, and it's "Executive Manager" (who never has even bothered to place a call or email or letter to me, after signing for a Certified Letter from me), and have discussed this matter with an attorney for further action.

You are correct - a vehicle in this price range should not have a problem/defect like this, as you say, and I agree. And for Infiniti to know full well this is a common problem (they admit it), and not address it for 3 model years (2011-2013) is insulting. I have a co-worker with an 11 that has the identical issue, as well. The local dealership has already seen 3 at last count witht he new 2013's with the same issue - this came to me from the Service Manager!
 
Years ago, we had a toyota 4-Runner, don't remember the year exactly, perhaps a 1987-1988 with almost the same issue. But this vibrating noise came from out front, under the engine hood and on the left side. I mentioned it numerous times and finally somebody at the dealership went inside and came back out with a piece of foam rubber and placed it under a wire/cable that ran the length of the left side of the engine compartment. I don't recall what the cable was for, but it was plastic clamped to the side wall of the engine compartment. When it was cold, the cable would vibrate against the metal housing of the engine compartment. The foam rubber cured the issue until I sold the vehicle a few years later.

I haven't looked of late to see if I see any cabling like the Toyota's on my 2011 QX56, but it could be something as simple as this.

Hoping for the best possible outcomes to all.
 
Ronretro; thanks for the consoling message. It is a shame that Infiniti Engineers ignore this problem, because otherwise the vehicle is excellent.
