Your fuel gauge is reading incorrectly from the start. Your car's 17-gallon tank is only showing as full at about 13 gallons, and the gauge shows empty when there's actually 4 gallons remaining. This means you could run out of fuel unexpectedly if you rely on the gauge to know when to refuel.

Your fuel tank won't accept a full 17.2 gallons when you refuel from empty — it stops after only 11-13 gallons. This appears to be a fuel gauge or distance-to-empty (DTE) display problem that could cause you to run out of gas unexpectedly and get stranded on the road. The issue may require a fuel gauge sensor replacement or fuel tank inspection to diagnose and fix the problem.

Your vehicle's fuel gauge shows 0 miles remaining, but you can only fill up 13-14 gallons instead of the advertised 17.8-gallon tank capacity. This means your actual driving range is around 350-365 miles per tank instead of the expected 460+ miles, forcing you to stop for gas more often than anticipated. Your dealer says this is normal operation with no available fix.
