Okay guys I'm out of ideas here. For about 4 months now my car will randomly start pulsing at highway speeds. It feels like I have a flat or i'm my tires are very unbalanced. This happens so randomly like sometimes I'll see it twice a day (it happens for about 5 minutes each time, or sometimes it stops pulsing when Ibrake to a complete stop) or I won't see it for 3 weeks with a lot of driving. About a week ago I got my tires balanced and appearently everything is "perfect" now.

When it starts to pulse, it's normally after merging onto the highway or when I'm going down some windy country road. It'll pulse without me touching the brakes but if I do touch them, it gets amplified probably 3x as loud and intense. Then a few minutes later, it just fades away in seconds.

Can anyone help me out here? What could this be? I was thinking I have warped rotors but that wouldn't explain why the car would pulse even if I wasn't braking, would it?

Any help would be greatly appreciated

Rotors are spinning regardless, and if that was your problem then of course applying the brakes would make it worse. I'm not certain what it could be, but I would just take it to your mechanic or your local Honda dealer.

Are you driving on SO2s? How many miles do you have on your tires?

If you are doing a great deal of highway driving, it is possible that you have an uneven wear pattern on your tires and when the wear patterns line up on both sides of your car, the sound gets amplified (harmonic frequency). You might hear it more when you apply the brakes because when the tires are lined up just right, going slower (closer to around 20 mph) the sound is the loudest.

I'm not saying that this is your problem, but my car did this and I couldn't figure out what it was. Eventually, the noise happened all the time and it completely went away when I replaced my tires. I do a lot of highway driving.

Currently I'm driving on Fuzions with about 17k on them. I must stress that I feel it more than hear it. I can barely hear any problem when it happens, only feel it.

do a search on this topic, me and some other members suffer from the same thing and have not figured it out yet.

They didn't put rear rims onto the front, did they?
