Very disappointed at our brand new 2022 Taos. We have it only for 3 months, 1800 miles. Now the gas mileage display is messed up. The reading doesn't show the on time real mileage anymore. We have taken pictures showing after we have driven over 50 miles, the fuel mileage display remained the same. Apparently there is problem with the accuracy here. Got it serviced, showed our proofs with pictures. At the end, we were told this cannot be fixed. They explained that it's only an estimate and average readings. How could that be even right? The gas mileage display should be an on track real time, its accuracy is important for you to know when we need to refill the tank. That's not acceptable to just go by an estimate and average. The car was showing it right the first 3 months. From one day to the next, it's now messed up and the service department said it can't be fixed.

I will for sure. Thanks for the suggestion. At the dealership, they wanted to convince me that is the way the system works. But clearly is not the case. I called another dealership and will make the appointment for next weekend.

It's quite possible to drive 50 miles and have the range not change. For the first few miles your fuel economy is worse as the car is warming up. It estimates the remaining range based on that. Once the car is warmed up (or you are now cruising on the freeway perhaps) your fuel economy is much better. It uses this new average to calculate the remaining range. I've even seen the estimated range increase after the car is warmed up or if I get into a longer cruise.
Bottom line - yes, it is an estimate. It can only predict range based on what has happened, not what will happen. It has no idea what traffic will be like or how you will be driving for the rest of the tank. Once it tells you that you are down to 10 miles range, that will be pretty close!

These are the facts. For the First 1800 miles, the range to empty display worked well. It was until last week that it got stuck for a few days. That feature has only one simple use, for one to know how many miles left before you run out of gas. Now , I don't know that. So that even a safety feature to be stranded on the road without gas. Even the lines that show how much the fuel tank has left do not move. Wish this won't happen to you ever.

Oh, the actual fuel gauge is not working? I thought you were just talking about the estimated range.
Does it register full if you fill up the tank? And then either drop a bit then stop or not drop at all?
Another interesting thing would be to check the calculated fuel economy for a trip - if the fuel level sensor is broken it would think you had used no fuel and report insanely high mpg (or more likely, nothing at all).
This is definitely something the dealer should be able to fix. It sounds like they, as did I, misunderstood the problem which seems to be that the fuel gauge is not working. (It is quite possibly the in-tank sensor that is malfunctioning)
