Was very weird as I pulled into best buy parking lot. My car just clicked off and then the screen said Headlight Leveling Malfuction or something like that. The car started back up and still had the warning on the LCD. After I parked and went into best buy, the car restarted as normal with no warnings.

Has anyone experienced this before. Why would the headlights make the car die? Or is this all related to something I should be planning on replacing. Alternator maybe?

not sure about the car dying at low speed but HID leveling malfunction usually occurs if you hit the headlight leveling sensors on one of the four corners of your car. were you rolling pretty low at the time and hit something hard underneath your car?

Ha Ha maybe... But I was literally rolling through the lot which was smooth. However while driving back to vegas from VIP fest I did hit some bad soCal pot holes while on my lowest settings.

The most common cause of engine dying at low speeds in my nearly 24 years of driving LS400's have been a failing battery. But check to see if there are any stored problem codes.

Like Kansas said, could be a failing battery, or like I said in the pics thread, it's happened to me and been a loose battery cable/connection..... Could also be a loose main ground(s). My LS has a badly deteriorated positive battery clamp and needs replacing. It appeared to be the cause of a hard idle dip I had earlier this year. Cleaning and tightening the **** out of the clamp seems to have resolved the issue for the time, I just haven't gotten around to replacing the clamp yet.

I'd check my battery and cable connections first, then take it for a battery load test and charging system test. Most batteries do not last longer than 4-7 years(depending on the quality of battery, good batteries last longer) and even less if you are cycling them a lot with a lot of demand or running them dead and recharging them.

Also, if you have recently had a dead battery and got a jump but did not do a proper static CHARGE on the battery, you could have a dead/dying battery and repeated jumps without a proper charge could also kill your alternator!
