I am having issues with my hyundai. The check engine light has been on for sometime, and the engine codes say "limp home". The car does shift rough sometimes but my main problem is when I am accelerating at high speeds ( 60mph and above) the car shakes/ vibrates. I do not think that it is the balancing of the wheels because it only happens when I am accelerating, if I take my foot off the gas ...

I like this car. The only issue I have with it is that it makes a "rattle / vibration" sound when first started, especially when backing up in cold weather. This goes away after a few minutes of driving. I've seen other drivers on online forums with the same problem. So far no one has an answer for what this is - including Hyundai. Otherwise it's a great car for the price.

My dashboard top facing the front windshiled strted to spilit on driver side because of the Sun. I can still push it down and it stays for a day or two, Is there cheaper way to fix it?
