My ABS warning light remains on sometimes especially in cold weather when first starting the car. Last winter it only happened in extremely cold weather. It goes out after the car has warmed up only if you turn off the car and re-start. The dealership says it is a faulty light - they did were not able to fix - but says the ABS system is fine. Recently the light has come on when the temp drops to only 60-65 degrees. Any one else experiencing this?
