Why is my Kia Rio accelerator not responding at high speeds?

I've noticed that my Kia Rio's accelerator becomes unresponsive when I am driving at high speeds. This can be dangerous and I want to know what could be causing this issue.

It is possible that your accelerator pedal is malfunctioning or there could be an issue with the throttle cable. It is important to get this checked by a professional as soon as possible to avoid any potential accidents.

Your Kia Rio may also have a faulty fuel pump or a clogged fuel filter, which can cause problems with acceleration. I recommend taking your car to a trusted mechanic and having them run a diagnostic test to determine the exact cause of the issue.

In some cases, a dirty air filter can also affect the performance of your Kia Rio's accelerator. Make sure to regularly replace your air filter and keep it clean. This can prevent any potential issues with acceleration.
