NHTSA Complaint #11633686 — 2024 MAZDA CX-90

The fuel gauge and range indicator are faulty. I was doing long-distance highway driving during the holidays. At 1/4 tank, the range indicator said 110 miles until empty. As soon as the needle dipped a fraction below 1/4 tank (about 20 miles later) the range indicator dropped instantly to 40 miles left AND THEN DROPPED ONE MILE PER SECOND UNTIL IT REGISTERED ZERO. The needle also fell at the same rate until I was driving on the interstate with zero range and a gas gauge buried below empty. All of this occurred within one minute. I pulled into the nearest gas station and filled up with 12.71 gallons (it's an 18.5 gallon tank). So I actually had 5.79 gallons left (or 156.33 miles of range at 27mpg on the highway). Not being able to rely on the gas gauge/range indicator is a safety issue.
