A couple weeks ago, the check headlight leveling system light came on. Tonight when I was driving, the warning light came off. But when I stopped at a stop light, after 20 seconds or so, the headlights pointed down briefly then pointed back up to their normal level and it did this intermittently. Any ideas on what's going on? Thanks all!

 

Best guess is the height control sensor at the rear left of the car is giving a bad signal. Did you drive over something recently? Crawl under and have a look it has what looks like a mini sway bar link attached to it.

 

Thank you @LeX2K , will take a look!
