No Low Level Fuel Warning and Blinker Issue

Randy Johnson · 07-20-2021, 10:08 AM

I was driving this past weekend and got down to under 1/8th tank of gas. I never got the low fuel warning on the dash. I checked the mileage left and it showed 28 miles. I usually get the warning around 40 miles left. Not sure if this is just a 1 time occurrence. Just filled up the tank so I'll have to drive a for the next week or so before the warning should come one. Anyone know of the fuse that controls this. Another issue I am having is when I turn on my blinkers they work fine for the first few seconds and then the clicking sound and light indicator in the car start to go faster (quicker interval). It doesn't happen all the time but seem to be happening more often. Wondering if I have an electrical issue starting up.

Estimated mileage is purely based on your driving style at the time. If you are driving really aggressive, stop and go, etc, it's going to predict lower distance.

Fast blinker is usually a defective light (IE one left blinker isn't working anymore). Does it do it for both left and right, or just one direction?

I am not getting a low level warning even though the tank is less than 1/8. Used to always go on around 40 miles left mark. Now it it not.

Yeah for the blinkers I suspected a bad bulb but all are working. Maybe 1 is going out slowly? It happens on both sides but is random. Not every time I use the blinkers.

I would suggest not letting it get that low.

Nevertheless, the warning does go on, or is supposed to, at ~50 miles. I believe another warning is given at 30 miles.

The 2 issues , indicator light and low fuel warning, may not be related. But advice like “…not letting it get that low” is not helpful, IMO. There is an issue, get it checked.
