when letting off suddenly on the gas, our headlights will momentarily dim. the dealer says this is normal due to all the electronics. its disturbing to us. any ideas? p.s. we also have the cold start 'ticking/knocking' sound in the other question.

    If the lights dim on deceleration and you have any sort of a warentee I would ask them if there is an uprated alternator and complain that you feel it is a safety issue, see if it can be covered for free.

    I lived with this annoying problem on my '06 Azera for a long time. My car would turn the lights on and off frequently. I thought the "hommies" would come after me! The alternator is fine; don't start easter-egging this problem. I fixed it by disconnecting the battery terminals, letting it set while I changed the oil. After reconnecting the battery cables, the problem was gone. I thought that the on-board computer just needed to reset and reboot. Try it. You will see. And yes, you will have to reset the radio stations.

    I recently had this problem with my 2006 Azera. The problem was due to a weakened battery. I replaced the battery and the problem went away. It has been 6 months and I haven't had the problem since.

    I had the same problem. They tried re-grounding the car and suggested a new alternator. I insisted they replace the entire wiring harness from the battery to the alternator. It was expensive but immediately solved the problem. That was at least a year and 25K+ miles ago and the problem has never reoccured.
