Hello,
I wonder if anyone can help me answer this question. When my TL is running around 55mph @ 1.5rpm and keeping steady the car starts to vibrate. if i speed up or slow down it'll go away. I took it to the dealer and they couldn't experience what i told them. I'm wondering if anyone out there has the same problem?
thannks for reading.

 

the whole car shakes or just the steering wheel? what year is the car? auto or manual?

if its an 04 auto (like mine) there is a service bulletin about this issue. heres the link

i had this same issue years ago and this tsb solved it

 

i checked your other posts and you say you have an 04 non nav. so im assuming its an auto as well. you may need to have this service bulletin addressed. you can check your car to see if this "dynamic damper" is installed. remove the clips that hold the splash guard in place underneath the engine and swing it out of the way. if you see a black looking rubber box held in place by a bracket, about the size of a softball then you have it installed and there is another issue. if its not there then get this tsb taken care of. check the link to see what im talking about. i could take pics of mine if you dont understand

 

thanks, i read the description on the bulletin and it describe exactly my problem. I didn't have a chance to check them out yet. Now is this something easy that u can install yourself? or should i leave it to Acura to take care of the problem? thanks again!

 

bring it straight to the dealer. service bulletins are done for free if your still under the original warranty but since your an 04 your definitely out of warranty.

the service bulletins say this "Out of warranty: Any repair performed after warranty expiration may be eligible for goodwill consideration by the District Parts and Service Manager or your Zone Office. You must request consideration, and get a decision, before starting work."

bring the car to the dealer and ask them if they will do the fix without having you pay for it before they work on it. mention this particular service bulletin so they know exactly what to look for

 

That TSB has been done on many cars, and although some have said it has helped, it doesn't seem to completely eliminate the vibration at that rpm.

 

well, i have been really busy with school and didn't get a chance to take the car in. but new problem came up. when i came to a complete stop, i felt a vibration on the steering wheel. Does anyone know what's going on? I feel like my car's having too many problem. thanks for reading

 

well i took it to the dealer today and they gonna fix it for 200+. We'll see if it's working tomorrow.

 

I need new rotors so can anyone suggest on which one i should get? or should i just order from acura? thanks

 

So what is the outcome of the fix wreckon06?

 

after driving it for a while now, i can tell that the vibration is still there. But it's not as violent as before.
While driving i feel the vibration in the steering wheel if i keep the speed constant. however, when i speed up it stop vibrate. This is in general not just at specific speed. Also at a complete stop i can still feel the vibration. Idk if this is due to wheel balancing or the engine mount. any suggestion? Acura doesn't seem to be able to figure out my problem. thanks for reading!
