“My 2004 Kia Sorento has an intermittent check engine light that displays error code p0446. The light comes on and off as it pleases. There is a TSB for this particular problem, but there are no details. This intermittent light is causing my vehicle to fail it's smog inspection.

This is a safety hazard as I never know when my brake lights are out unless someone stops and tells me.”

My newest issue is with the heater, it will only blow warmed air if the motor is being rev'd..temp is warm on engine but if I am driving down hill, it will feel like air conditioner instead. For a few months my driver side door would open from inside only. Magically it has resolved that one and only issue...”
