From owner reports, verbatim
I purchased the bike in Feb 2023 and the fuel gauge has gone bad. Problem is wide spread with this and I have seen and documented people having the same issue with the whole line of their bikes. I believe since this was part of the gas tank and the tank could possibly leak where the float sensor connects to the tank itself, it should fall under the EPA warranty. At first they will going to honor my request to just replace the float switch inside. However, they have came back to me stating the bike is just out of warranty and refuse to cover the part. The bike would have to be taken to a authorized dealer which is more than an hour away from me. I tried speaking to them telling them that I called the dealer and they were really backed up and no able to take the bike in at the time (called in Oct of 2023) My 2 year warranty ended in December 23. However, at that time, I was told the bike is covered and not ending in December. However the shop still, up to this day, says that they are full on bikes atm and I would have to wait to bring it. This part is known to fail, aprilia knows its known to fail and it seems like this item should be recalled. It could lead to more issues down the road with the gas tank.
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
