Hi:
I have a 2006 Hyundai Tucson (4WD, V6) with battery issues. If I don't drive the car for 4-5 days the battery dies. Other Tucson owners (2006 models) have also had this issue. The dealership has done the following:
1) replaced the radio (it was drawing way to much power when the engine was off) and battery. This didn't solve the problem.
2) reset "all the codes" (their words) to see if that would help. It didn't.
3) rechecked to see if there was any other battery drain and they said they couldn't find anything.
Right now I'm dealing with Hyundai USA to get a buy back. In the meantime, can anyone suggest any other possibility for figuring this problem out?? all the repairs and diagnostics have been free under the warranty, but I'm tempted to take the car to my local garage (great mechanic there) to see if he can find anything.
One thing I have noticed: If there is no one in the front passenger seat, a 'Passenger Airbag Off' message light comes on. Then when I use the turn signal, this message light flickers faintly in time with the turn signal clicking. As far as I can tell none of the other dashboard lights flicker like this.
Thanks!
