I got quite a few problems on my g35 and any feedback would be great!!!

first problem is wen i hit 65-70 mph my car goes crazy with sum hard shaking and quite a few jerks, but one it passes or is under that speed it rides super smooth, did wheel balance, alignment, new brakes and nothing.

second problem is i notice after a drive i come back home and my driveway is slanted a bit but from the bottom right side of the radiator the coolant starts to leak, not while im driving after ive droven it and put it in park, what can that be?

third problem is my horn dont work, changed every fuse there is nd still nothing.


Any feedback will help negative or positive thanks!!!!

 

Check your suspension bushings.

 

Do you have aftermarket wheels? I needed hub centric rings on my winter wheels or I would get really bad shaking at that speed. Maybe one of you wheels is bent or tire is damaged as well.

Your radiator could leaking. I'd rent a.pressure tester from am auto store and test it.

Did you check the relays?

 

OP it sounds like you need to take your car to a mechanic to get it fixed properly. It doesn't sound like you are much of a DIY guy.

 

 

horn not working means more than likely your clock spring in the steering wheel needs to be replaced, I had the same problem, I bought a used one on ebay
