Car vibrates when decelerating at high speeds
Hi all,
was wondering if anyone may have an idea what the problem might be. When I'm on the freeway going about 75-80mph (sometimes happens at lower speeds too, like 65-75) and I let go of the gas, the car vibrates and it's pretty noticeable/annoying. It also seems to vibrate more when I release the pedal halfway instead of letting go all the way. So if I'm going around 80mph, then let go of the pedal halfway, it vibrates pretty hard. Any idea what it may be?
Thanks!

This....^....indicates you have warped rotors which can be easily corrected. Warped rotors are generally the result of tire monkeys over tightening your lugs with an impact gun, sad but true!

But its only when i break between 70-80mph, if my rotors were warped, wouldnt my car vubrate at all speeds?

yes your car should vibrate at all speeds if your rotors are warped. but could be more effective and higher speeds. does the steering wheel shake or does the whole car shake?

If the whole car shakes/vibrates when decelerating I'd have the suspension/alignment checked closely. The warped rotor issue would be felt in the steering wheel first, at speed I've had it move back and forth 2". That's not what you want to experience when trying to stop, that's one of those "What the" moments....Gary

Doesn't sound like the brakes to me, and because you only describe the vibrations happening during deceleration I don't think it's got to do with the balance on your wheels/tires... My guess is a bushing or something. I would start there by going to a dedicated suspension shop to see if they notice anything abnormal.
