I bought my 300c 12/31, at night. Believe it or not, today, 1/11, is the first sunny day since then.

I guess the lights have been on every time I drive it, but I've never had any trouble seeing the nav, indicating headlights when it's light outside.

Today, in bright sunlight, I noticed the nav was impossible to see.

I deduced that the auto headlights were on, so I switched the dial from "A" to "O".

Reading the nav problem solved, but why are the lights on when the sun is blazing? I couldn't find an obvious sensor, but there are no obstructions on the windshield.

The car was facing almost all compass directions during my drive, there were some bridges, but none after I noticed the lights stuck on. It is a cloudless day, the sun was well up during my comute.

Several cycles of the switch to "A" and "O" didn't cure the problem.

Any ideas?

The sensor is the round thing in the center of the dash by the windshield. I know when I start up the car and haven't removed my sun shade, the lights come on. Sounds like you have a bad sensor.

False alarm, must have been a temporary glitch.

As of today, all is well.

That happened to me too... remember, if the window is foggy it will think its night that was my case... also the whipers kept going without a drop of rain.

I have this same problem. My 300C is in the shop this week for the 8th time since I got it last August.

You might want to check the next time your lights get "stuck on", if your
hi-beams will flash. Mine will not, when the lights are "stuck on". I also keep the fog lights on, and they will not turn off when to lights are "stuck on". The dealer is working on fixing the problem. I will advise if they do.

Old post.. but did you ever figure out what the issue was? I am experiencing the exact same thing. Thanks

Old post for sure, but it caught my attention because I had the same issue when my car was brand new. My car is an '06 that I bought in September of '05. The dealer flashed the computer and it has been fine since. I thought I was the only person who had this issue, never looked it up here on the forums because at that time I had not yet found 300cf.

talking about pulling up the dead LMAO....


i have this same issue in my 2012 except the headlights are stuck OFF in automatic mode. they work in the manual modes just not in automatic, might just take to the dealer as someone told me (off forum) the computer needs a flash.
