Transmission Problems? Ask a Mechanic for Answers ASAP
Hello, do you have brake lights? And when you step on the brake pedal and the vehicle is in park do you hear a click at all?
Alright, I'm going to recommend you replace the brake switch. It its on top of the brake pedal bracket. There are a few different circuits in it, one for cruise control, one for the lights, and one for the park release switch. Kia has big problems with the brake switches going bad. I have attached a picture of the switch location.
Sorry for the delay. There are no common issues that I could find. These systems are totally unrelated so I'm not sure how this could be happening. Check all fuses in the interior fuse box as well as the engine room fuse box that are labeled ECU. If all of those are good, I'm going to recommend you replace the transaxle range switch. It is located on top of the transmission. Aside from this, the only option I see is a bad PCM because none of these systems are related and they all seem to be working fine separately. I have attached the procedure on how to replace the switch.
I'm gonna open this up to other experts to try to help you.
