If you are stuck with a lemon, then you need to take the car to the place where you have purchased it for repair. If the manufacturer is unable to fix the issue and if they are not ready to pay for the repair then you are entitled to compensation. But because of depreciation, the value that you get in the form of compensation might be lower than what you have paid for the car. This is because the depreciation keeps on decreasing with time and the more you drive your vehicle, the lower its resale value will be.
This is why it is necessary to file a claim for lemon as soon as possible rather than rehashing it even after multiple visits to the garage. At the same time, it is necessary to get in touch with a KIA lemon lawyer since lemon law is quite complicated.
