Default Car shakes and vibrates over 80mph

When you go over 80mph the car shakes and vibrates. You can feel from the floor. It happend after i went over a huge pothole.

Any ideas what this could be? I think it must be something in the suspension or motor mounts. The weird thing is the car feels fine otherwise even with cornering,etc.

My car is still under warranty, anything you recommend that I ask them to check out?

sounds like your rim(s) are bent from the pot hole. Either that or way out of balance

Yeah, wheel issue, most likely. I would visually check the suspension as well, but it's very easy to take the car to a tire shop and have then check for out-of-balance or out-of-round wheels.

If it's road damage from a pothole, it's not going to be covered under warranty. Should be covered under insurance, though. You also might get whoever is responsible for the road to pony up some cash in compensation. Some places do that.

Thanks guys will look into it.

Can a bent rim be repaired if its not too bad? Also is this considered comprehensive for insurance?

One more thing. Before this incident i notice that my steering wheel was slightly off center to go straight but the alignment felt just fine (goes perfectly straight with hands off wheel) . What do you think? Also will honda try to blame this on the pothole as well? whats the best approach with this.

Me? No. But there are wheel shops that can.

The off-center steering wheel is easily fixed (or caused) by your alignment tech.

So i went to take care of this issue. My alignment and wheel balance was a bit off from the pothole. Also both driver side wheels were bent on the inside and a small gash on the tire. They told me that i could get the wheels repaired for about 100 per wheel, but sometimes wheels crack if not repaired properly. I got all 4 wheels balanced and aligned. They told me it the wheels should be fine on the road for awhile and that i should think of replacing eventually.

This is horrible, my car only has 6k miles and my rims are screwed.... I am thinking of driving until these tires are bald then just pick up some aftermarket wheels/tires. I can probably collect some cash from city or at least insurance for the damn pothole.

I have aftermarket wheels with hubcentric rings, but not installed. I hit a pothole, and had real bad vibration at 20 mph. So I took the wheel ( it was the rear that was hit, and I didn't take the fronts as the steering wheel wasn't shaking) and had the wheel repair shop in Greenville, SC, take a look at it. He checked runout on it, and said it was well within factory specs. Then he told me it was the wheel being knocked off center by the impact.

So I installed the hubcentric rings, put the wheel on, and everything is fine.
