TSX not smooth at high speeds
Hey all,
What could be causing my TSX to not be all that smooth when it reaches approximately 65mph and up?
The steering wheel becomes shaky and does not feel very smooth.
The road was in decent condition.
I installed a K&N drop in filter the other day. I don't think this is the source though.

that sounds very abnormal....smooth as silk for me an the steering at speed is quite tight. I check all your inflatinos on your tires..... any big curb checks lately? alignment might be off.

Does it eventually smooth out at higher RPMs? I have begun noticing the same thing. mainly in 6th gear approaching 3000 rpms i feel very slight vibrations. It seems to go away by 3500 though. I 'm not 100% sure if I can feel it in other gears..so it might be a product of the particular speed, rather than the rpms. I actually posted a while back about engine roughness between 2500-3000 but still havent had any kind of resolution.
EDIT: The vibrations I am experiencing are very minimal. Have to really accel slowly and pay attention to feel it. Not sure if yours are like that or worse.

I'll be "experimenting" with it a little more and will bring it up with my dealer. If you find out the problem or get some info from your dealer please post because I a very interested.
I am going ot have a laundry list of things for the dealer to check out when I bring my car in for the first oil change! I fiugure I'll have a mechanic tied up for an entire day.

It's a negative that the K&N has any influence right?

As for my list..you asked for it so here it is...
1/ Rough/Notchy/sometimes grinding shift 1-2.
2/ Rattle from middle of pass door during loud music.
3/ Buzzing from both front door locks during loud music (and sometimes without music).
4/ Squeaking Sunroof (easily fixable I beleive)
5/ Low rattling which seems to be coming from drivers side window.
6/ Metalic Rattling coming from drivers side only when sunroof is open. May be seat belt adjustment. (5 and 6 may be related).
7/ Intermitent ticking sound from back winsheild area over bumps.
8/ Center of dash creaks over some large bumps.
9/ Vibrations and roughness approaching 3000 rpms in 6th gear.
This should keep 'em busy for a while. My biggest worry is most of these problems seem to be intermitent or only occur under certain conditions. I'm worried I will get a "cannot reproduce" for some of them which will piss me right off.

mmmm, most likely an out of balance wheel, alignment, or uneven tire pressure. if you have mount new wheel yourself, uneven space can also attribute this... but... seriously; you shall call the dealer to make a appointment ASAP and have them solve this problem, this is not your duty nor responibiity to seek solution, it's theirs and they will do a better job.....
hope things go well from here!!!

I just wanted to assure that the problem is not rooted from the filter itself.

I have the same problem...steering wheel shakes/vibrates when i go 65-70mph. it's at the dealer right now to be checked on. another problem i had was the plastic spacer/buffer in the sunroof whould vibrate vehemently around 40mph when its fully open. don't know if these two are related but they might be...dealer is checking them out for me. i'll update once i hear the dealer diagnosis
in the meantime i have a TSX MSM/qtz/auto loaner

but i also called Fountain Acura just to compare prices and Fountain was cheaper for some things. so the service dude at Courtesy told me to just get a fax/printout/etc from Fountain and they'll match it

My family and I have purchased all of our cars in the past 7 years from fountain. They have treated us well.
This morning, while I was on the turnpike, there was no vibration!
I'll pay special attention to it later on this evening on my way home.
I just realized how much thicker the stock air filter is when compared to the K&N i dropped in. Wow! Does this thing not filter as well?

Steering wheel shaking at a particular speed, especially around 60 to 75mph, is a symptom of unbalanced wheels. Swap the front tires for the rear and the problem should seemingly go away or change in someway.
Warped rotors will *ONLY* shake your steering wheel when you are braking.
Alignment problems rarely produce wheel shake. Usually an alignment problem will cause the car to pull to one side, or seem unstable at certain speeds (car tends to wander and require constant steering correction).
Extreme tire under or over inflation (by 10psi or more) will cause alignment-like problems, but other than that, improper tire pressure usually just result in changes in ride softness and steering effort.

In my case my tire pressure is definately not the culprit. I agree it cant be rotors because I am not braking. What I am still trying to figure out is if it happens and certain speeds, or certain rpms. I definately feel it around 3000 rpm in 6th...but may also feel it (just not to the same degree) in other gears at this rpm.

i just got a call from the service dude at acura and they said they're going to rebalance all 4 wheels and see if the shaking goes away. hopefully it'll be fixed when i pick it up tonite. i'll keep y'all updated...

Yup, i was thinking the same thing on the way to work today although I didnt have a chance to try it. The vibrations I am talking about very slight... so i'll have to really pay attention.

yeah i've tried that, i actually put it into neutral and let my car roll going 75->70->65->60mph on the highway and it still shakes. if anyone tries to test this way make sure you have no cars behind and rev up when you reengage your clutch, of course y'all knew that already

dabuda...how bad are these vibrations? Are they very slight..or are they very noticable?

i picked up my tsx last nite and drove on the highway for a half-hr. the steering wheel shakes are gone!
the dealer said the factory balance was incorrect so they just rebalanced all 4 wheels for me

It's most likely balance of tires/wheels. If a standard balance doesn't help fix the problem, goto a place a "road force" balancing machine.
check out this article
http://www.broadwayautoclinic.com/Balancing.htm
This machine did wonders for my 4runner which not only has huge stock tires, but also has the sensitive feedback rack and pinion steering and body on frame construction which makes any feedback fromt he road really sensitive. The shop did the regular balance like 4 times and i still had vibrations and shaking from 70mph+. I then heard about the road force variation and went to another shop to have them get it done. After it came out, i tested the tires on the highway and the car literally drove like it was driving on glass. SMOOTH AS SILK. You also only have to do this type of balance once. Cause for the rest of the life of your tires, you only need to do the regular balancing for the remainder of the time.
Hope this helps
