#1426 of 2128 Vibration in Floor/Pedals at 2000RPM
Aug 05, 2005 (2:23 pm)
We just bought the 2005 Quest SL and we love it... with one exception. When driving at 2000 rpm (either accelerating or decelerating to), there is a vibration in the floor coupled with a louder than normal torque/rev sound. Although it's not as significant as some of the vibration problems that I have read, it's certainly annoying.
I took it back to the dealer and I drove 2 other 05 SL's and they behaved the same way. The tech told me that there is nothing in "the book" on this and there doesn't appear to be any problem with the engine or transmission. He said it appears to be "normal". For a new $30K vehicle, it's doesn't seem normal to me.
I found a Nissan Service Bulletin indicating that the 2004 SE built before January 2004, had a "booming noise and/or floor vibration at about 2,000 RPM" because a mass damper needed to be installed onto an exhaust hanger (???). Could this somehow be related?
My feeling is that there is something that needs to be adjusted, but until they get a Bulletin from Nissan, there's nothing that can be done and I guess that would only happen if enough people complain to Nissan N.A.
I'd appreciate any info/feedback or suggestions or to find out if anyone else has experienced this.
#1427 of 2128 2005 Quest Warped Rotors
Aug 05, 2005 (4:43 pm)
I own a 2005 Quest 3.5S with 3500 miles. I started to get a vibration in steering wheel upon braking also could feel the vibration at highway speed in the steering wheel. I called the dealer and got in the next day. The dealer was well aware of this problem. They used a on the vehicle rotor lathe. It took one hour while I waited. The brakes are fine now. I decided to do some research on this problem. I found why this problem occurs, lateral run out on installation of rotor. Go to www.performanceoiltechnology.com/brakingsystems.htm and read this article. It speaks of the PRO-CUT hub mounted computer controlled on vehicle brake lathe. Now go to www.procutinternational.com click on awards/evaluations, look down the list to Nissan TSB 04066. This is the only fix Nissan warranty will pay for. It seem that the rotors are of good quality, the problem is in the installation of the rotors, over torqued lug nuts etc. This Pro-Cut tool is mandated by most all major vehicle companies. The tool costs $8000.00.

The window lock button does not illuminate. You will find this on most Nissan. Why? I don't know, maybe it's not used often enough to jusitfy putting a bulb under it.

Check my posting, # 1409.
I know it is unusual for an out of alignment condition to manifest itself as vibration. I felt vibration up thru the steering wheel, and thru the floor. Plus a side-to-side wiggling. It made my calves shake...
My experience is, after re-balancing tires N times, and then replacing all four tires, the alignment (which did show both the front & rear whells to be out) made a dramatic improvement and ultimately fixed the problem. I have since driven over a thousand highway miles, and the van is extremely smooth.
And of course, Nissan was cluesless. They did load balancing, and diligently checked all bolted connections on the front end to see if anything was loose. But they neglected to check the wheel alignment. I did it on my nickel, on a lark while getting the oil changed at a local tire store. Best $40 I spent in a long time, plus 3 year warranty.
After thinking about it, I can see how mis-aligned wheels could cause the tires to wear, and then get out of balance. Oddly, the van tracked pretty straight on the highway, both before and after the alignment.

I have my 04 Nissan Quest for more than 6 months now and on the third month since I bought it I also noticed a vibrating noise coming from underneath the vehicle. It starts at around 2000 rpm you'll notice it everytime you accelerate. It sounds like the heat shield is vibrating. I took it to the dealer for 3 times and they keep telling me its all gone after they fix it, but everytime I drive it its still there. They even told me that the next time I bring it in, theyll have to replace the exhaust system and charge me for it. I think the vehicle is still in warranty, but I dont know why.And one thin I notice too is that a portion of my exhaust pipe is flatened. Should'nt that obstruct exhaust flow and hinder the vehicle's performance? Could anybody check their exhaust pipes if a portion is flattened and let me know coz to me it dosnt make sense. Marc.
#1431 of 2128 IT IS GONE FOR GOOD :)

I turned in my quest for good yesterday...... Nissan, only after a year of fighting with them, have bought it back under the law. I am glad to be rid of it, and only hope that my next vehicle will not be any problems, I am not sure any can be as bad as the quest was! If you have enough problems with your 04 quest as I did, don't give up if you really want it gone. Good luck to everyone who has and are still having problems.

We have a 2004 Nissan Quest that has had the same vibration problem for awhile. We assumed poor tire balance. Last Wednesday, we took the van in to the dealer for scheduled tire rotation and got the tires balanced. Vibration didn't go away. Called dealer and they actually mentioned "warped rotors," which at the time sounded like b.s. I guess it's not!
Do I understand you to say they fixed your problem under the Quest's warranty and you didn't have to pay anything? The TSB you mention is listed as '04/'05 Titan and Armada brake judder, but all Nissan dealerships will apply this to Quests as well? Your dealer seemed to be well aware of the problem, but I don't want them to try to pass this off as something peculiar with just my van. I want to be armed with as much documentation as possible when I take the van back to the dealership Monday morning, so anything further you can offer would be greatly appreciated!

There are two service bulletins that deal with exhaust vibration problems. I had the same sound at 2000 rpm on my 2004 SE and it was a broken bracket that holds the exhaust to the engine. The bulletin has good pictures showing good detail which bracket it is and where it is located. Its not too hard to crawl up under and see the crack. Bulletin #05021 shown at this link - http://www.nissanhelp.com/Ownership/Bulletins/Nissan/2005/NTB05-021.htm
The other vibration problem deals with a clearance issue with the rubber bushings and the frame of the exhaust system brackets. If the clearance is too small then the rubber bushing rubs against the bracket frame causing vibrations. They also have parts for adding a mass damper to reduce the vibration even further. Bulletin #04096 shown at this link - http://www.nissanhelp.com/Ownership/Bulletins/Nissan/2004/NTB04-096.htm
The sad thing is I had to print these out and show them to the service department before they would believe that there was a problem.
I had both these performed. The noise was instantly fixed and the vibration was improved, but not fixed. I still felt the unusually high amount of vibration through the gas pedal and the floorboard around 2000-3000 rpm and they ended up replacing the entire exhaust system (under warranty of course). It helped a little, but there is still some vibration that I think is more than normal. It may be something I have to live with.
Hope this helps.

Thank you very much for your message. The articles that you posted explains a lot of the problems have that reoccur. I appreciate your research!

Yes my dealer, Morries Nissan, Brooklyn Park, MN knew all about the problem with the rotors on the new Quest.Its the same problem the Titan and Armada have. The dealer resurfaced the rotors on warranty in one hour for free. They used the Pro-Cut hub mounted on vehicle brake lathe. This is the only machine that will do the job correctly almost 100% of the time. You must make sure your dealer has this machine to do this job. Also go to the web sites in my previous post #1427 and print out this info and take it to your dealer. They may try to say the rotors are only covered fo 12 months/12,000 miles. I would then call Nissan customer support.My vans symptoms started at 3000 miles. I felt a vibration in the steering wheel when braking. The faster land speed the faster the vibration when braking. I could also feel the vibration in the steering wheel when going faster than 55MPH and not braking. I thought this was strange, not just a warped rotor. My vehicle is fine now. I hope this helps.
