When the low fuel light and warning text show up on our 2021 Prime’s dash screen 10.5 gallons is all it will take and that is with the attendent (in Oregon) topping it off. The HV miles remaining will be around 20 and the fuel gauge will show well less than ~1/8 tank. Until very recently I had imagined the tank capacity was 11 gallons but then I looked it up and was dismayed to see it was 14.5. When I filled up and topped off after taking the photo it took 10.48 gallons.
A month ago the dealer repair rep had me take photos of the dash info just before fillup (as in the attached photo), just after fillup and of the fuel receipt and text it to them. I got a “We’ll look into it”. Two weeks later I had heard nothing and as it was time for my next fillup I did the above again. The reply was to set up an appointment.
Went through the above again on the day of the appointment, yesterday. I came away very dissatisfied. They are saying that everything checked out fine, meaning the sensors. It was suggested that perhaps the cool weather was having an effect. It was 48 degrees. Zero, maybe 10, degrees and you might get a hint at buy in on that theory from me, but 48, no.
I am currently making a once a month round trip between Oregon and California. Road closures are a possibility in winter and I want to have as much range availble as possible in case say a landslide blocks the highway and I need to turn around out in the boonies. The dealer’s repair rep suggested I keep a journal with info such as my odometer when I fill up. I told them while I might do that my needing to do so was unacceptable.
I had by then learned of the lawsuit because of this sort of issue with the Rav4 Hybrid 19,20 & 21 model years and I mentioned it but was told the issue was only with the Hybrid, not the Prime.
Bottom line is I just want my Prime, which otherwise I very much like, to have a fuel system that allows me to use around 90% of what is actually in the tank before it tells me, via the “Low Fuel!” indicator and lighted up gas pump icon that I need to refuel and when I soon do I have to shell out for 13.5-14 gallons of fuel not 10.5. Has anyone else had this issue with a Prime?
