I have an 08 IS250 with OEM HIDs, AFS and auto-leveling. I know that every time I turn the car on, the headlights aim low, then come up to the regular driving level. Lately, I noticed that the passenger side seems to aim a lot lower than the driver's side during the initial start up, but they would always line up to the regular driving level afterwards.

Today I started my car and the passenger side headlight's driving level is a LOT higher than the driver's. This has happened to me in the past, and I just adjusted it down to the right level after. What is causing this? Could it be a busted sensor or motor?

 

I think this is normal, driver is lower so you don't blind incoming traffic.

 

Its designed in that way to not to block incoming traffic. if u pay attention to other cars they all have different levels

 

I'm well aware of that. I'm saying that the passenger headlight was aiming significantly higher than the usual height. More than high enough to blind oncoming traffic in the left lane. Again, normally the headlight cutoff levels are the same, with the passenger being (very slightly) higher. But out of nowhere, the passenger side cut off was much higher than before.

I may just have to record a video to show exactly what I'm taking about, as it seems that this problem is either very rare or hasn't happened to anyone before.

 

Are you parked on a slant or hill?check your sway bar bushings.the rod is on the drivers side and if the sway is slightly slanted on one end,it will affect the lever
