Fuel gauge and related WEIRD stuff!
I did a search for fuel gauge issues and found some old stuff so thought I'd update that and add to this topic;
Mine is a new 2017 Canyon (below). Absolutely love the truck. I bought it on vacation in Florida, did a 500 mile "wear in" according to the Owner's Manual, then returned home adding another 500 miles. Since day 1 the fuel gauge does not work.....it reads full 99.5% of the time. Even after driving 225 miles the gauge does not budge off of full. I took it to the dealer, he said the float appears to be electrically free and indicates the tank is 99% full (I had about 180 miles since a full up at the time). The Range on the DIC info panel shows a range around 590 miles plus or minus, depending on the average MPG - I have seen 600 miles when I've been driving slowly on the highway, and around 550 miles when I've been driving in traffic. The gauge needle is not stuck; it goes through its normal empty to full to full when I start the truck.
Driving home my fuel gauge suddenly went to Empty...stayed there without any low fuel warning, etc until my next fill up. Then it went back to full and stayed there.
I also have difficulty filling the fuel tank. I can only put in about a third of a gallon before the gas station's nozzle does the auto shut off. This happens at all fuel stations I've used so far. So it takes me a LONG time to put in the gas. I have been filling the tank after 200 miles using the Trip A in the Info screen. My average MPG is excellent BTW, I was (Trip A indication) averaging 29.1 MPG over about 450 highway miles with speeds between 60-72 MPH. After the truck accumulates another 2-3k miles I might manually calculate the MPG, but at this point I don't really care.......<g>)
Any suggestions on the fuel gauge? I go to the dealer ASAP this week now I'm home again.
