One problem related to turn signal has been reported for the 2006 Hyundai Sonata. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2006 Hyundai Sonata based on all problems reported for the 2006 Sonata.
2006 Sonata now has an intermittent electrical problem. These problems manefest themselves usually when the gas is not being applied, but not necessarily when the brakes are being applied. The headlights will go off and then come back on; the radio sometimes will go off and then come back on; the a/c fan sometimes sounds as if it has turned off and then comes back on; several times I noticed the esc light and abs light come on when the radio and lights and ac turned off and then came back on. At times these outages will occur when the turn signal is used. All these happenings have been reported to the Hyundai service department but they say they can't get it to repeat the symptoms or find a problem.
