Tail light remains dimly lit while off

[Rik]

I just noticed it this evening, and timed with the car cycling coolant all day while not charging (new behavior), that the driver side outer tail light is dimly lit. it is lit whether unlocked or locked. I had my wife check that I wasn't seeing things. Anyone have this happen to them? Root cause?

Could it be the brake light? A stuck pedal, a weak spring or bad switch.

I believe the LED taillights have a driver module located near the taillight assembly. I had a problem with one of mine making a squealing noise for a few seconds when first turning on. This has gone away with either the colder weather or a recent firmware update. You could also have a bad ground connection. Have Tesla check it out.

It's going in to the local SC shortly. It's not a stuck pedal, so we'll see what they say.

Sorry, I didn't notice this was in the Roadster forum. My comment applies to the Model S. But they may be similar.

No worries! You may be on to something with a bad ground. I appreciate the input.
