I made sure that I filled up that morning. Then drove 18 miles to the dealer and it had already dropped below full. They took a look, determined that there was a problem and ordered the parts. I'll take it back in and let everyone know the results as soon as it is complete.
Same here. Got my TCU replaced with the 3G unit today, they tested and confirmed the fuel gauge issue. The service advisor said that after they get the parts they are going to need it all day because when the combination gauge is replaced it needs to be reprogrammed to the same odometer reading.
