A new front bumper for a 2013 Hyundai Sonata will probably cost between $100 and $1,000. That’s for replacement parts and having a professional install the new bumper.
That’s a pretty wide range, but if you get an estimate from a local repair shop they should be able to give you a more exact price.
Depending on the extent of the damage to your front bumper, you may be able to reattach and repair the old one. This can sometimes be the cheaper option, especially if the damage is minimal. However, if your front bumper needs extensive repair and repainting, it might actually be cheaper just to replace the whole thing.
