Q: I have questions regarding two vehicles. One is a 2007 Kia Sedona. Lately, the headlights have been burning out within a few months of replacing.
The other is a 2006 Hyundai Tucson. During the last six months or so, it has stalled out about a dozen times when I’ve been stopped, sometimes facing uphill and other times on level ground. The tach idles at 500 rpm. Sometimes the idle surges fast and then slow again. I added dry gas because I thought there might be water in the tank. That seemed to help short-term. Today, with a three-quarters-full tank of gas, it did it again on level ground.
A: Concerning the Kia headlights, have a charging system check performed. If the voltage is going over 15 volts, the charging system needs to be repaired. The bulbs are getting too much voltage and burning out the headlights.
Concerning the Hyundai, you either have a vacuum leak or the idle air control motor may be dirty and/or lazy.
Car Care Tip: A tip from my friend Mike: “When checking for rattles from the back of the vehicle, make sure you check your spare tire jack for not being locked down properly and floating around in the trunk.”
