I have a 2008 ISF with a very peculiar electrical issue. Virtually every morning when I start the car and the headlights come on, I pull out the garage and press the button on the mirror to close the garage and nothing happens until I turn off the lights. Sometimes later in the day this happens, sometimes not. I never have a problem opening the garage when I come home, it only happens when I pull out. Even then it doesn't happen every time.

Additionally, one to two times a week, when I go to my office and park underground, the car will not lock either on the door lock or the key fob until the lights go off. Invariably this happens when I have my hands full. I end up putting something down to open the door, turn off the lights and then I can lock the car. That is really annoying.

I have had the local dealer look at it several times and they cannot figure anything out. I suggested that maybe the battery was weak, but they tested it and said that is not the problem. I have spoken to Lexus customer service as well. They have no idea what the problem is. Both the dealer and Lexus have basically given up trying to find out the problem. I am curious if anyone else has experienced this issue or has an idea of what the problem might be.

I've had the same issue (more or less) with the garage door opener. I hadn't noticed whether it has anything to do with the lights or not. I've found if I'm just (barely) past the door and close it, it works pretty consistently, or if I close it from a bit down my street it works. Frequently there is a problem getting the door to close if I'm on the driveway proper and well out of the garage.

I've had problems unlocking the car if I've remotely rolled down the windows a ways off and the car re-locks itself. I then can't use the door handles to unlock. The fob works fine.

However, after reading the manual I found out this is normal. Annoying, but normal. :(

Good Luck,

Jeff

I live next to a Navy Air Station and have these same problems at times, but never messed with the lights. Normally i give it a couple seconds and try again and it works. When I am on the base and closer to the transmitters I have to put the fob next to the handle and starter button to get it to work. Just too much radio chatter out there.

Electrical Issue Resolved

Kudos to my local service manager for finally figuring it out. As I mentioned, the issue only happened when the lights are on. The local service manager decided to run a test on the headlights and discovered they were emitting a strong radio frequency. They replaced my headlights and the issue is gone.

WOW, they have the ability to check a signal or radio wave? Kudos for sure.

Radio frequency or infrared pulsing that in-consistent?

Glad they fixed it.
