The controls on the steering wheel don't respond as they should, the stereo controls still work fine. With the original stereo, the volume down button would only work sometimes, other times it would activate voice control, change modes, or do nothing at all. I tried upgrading my stereo, but it only got worse. The volumes swap randomly and the track skip buttons sometimes won't register. Online, people have said it is a frequency issue that can't really be fixed without just replacing the controls.
