The Automotive Parts Market is full of cheap alternatives. As inexpensive as possible, fitting non-Genuine or refurbished Parts to your Hyundai will affect the warranty of your vehicle. Those Parts are not manufactured under such stringent standards as Hyundai Genuine Parts. Fitting such Parts will not only hamper the quality of your car, but will also affect other parts and cause more problems, leading to more repairs, or worse, an accident.
So for your family and your safety, always insist on Hyundai Genuine Parts.
