I have been getting the low coolant light on and off for a couple days now. Fluid is where it always has been. I hope it's only the sensor like so many others have reported.

Mine did it for like a month then stopped all of a sudden.

I'm sure it's the sensor seeing how no coolant is gone.

Same thing , low coolant light , tank on the money . I see it a couple times a week , then a couple of weeks go by nothing . Doesn't matter what time of year or weather.

Mine was doing it also. Every time I checked it, it was right where it should be, cold and dead on the line. The dealer added fluid saying it was low. No problem since. There notes said "low on coolant with no apparent leak" :confused:

I have been getting the same thing on and off and one morning I checked the overflow tank and it was about 1/4" below the full line. I topped it off and haven't had a problem since. It must be very sensitive.

Adding coolant hasn't helped for me , still comes on w/ an overfilled bottle.

Was this one of the sensors that had a recall/reprogram on it. Seems to me right after I bought mine 07/06 I had to take it in to have the water in fuel sensor and another one reprogramed. Wasn't giving me any trouble, just got a recall letter

Mine turned out to be the lower radiator hose.

I hadthe same problem so I removedthe overflow tank and cleaned it out using denture cleanser tablets. Problem solved.:)

Anyone know a good dealer in central Florida. My low coolant light has been coming on about every 3k miles for the last 20k every time it does I have to add antifreeze. I don't see any bubbles in the overflow tank and haven't found any leaks.:confuzeld
