NHTSA Complaint #11673491 — 2025 CADILLAC XT6

During a cross- country trip, we had driven more than 300 miles, but the fuel gage indicated full, the Fuel Range Indicator showed a 688-mile range available in the tank which is much more than a 2025 Cadillac XT6 should indicate. The fuel gage indicated full even though it was not. I pulled the car over, shut it off and restarted, but it still erroneously indicated full. The indication remained that way for approximately 1400 miles. During the trip, while the gage still indicated full even though it was not, the tank was hard to fill. The gas station pump would automatically click off as if the tank was full, but it was not. I could only fill the tank by continuously over-riding the automatic shut off. This problem could not be duplicated by the dealership maintenance department on 4/29/2025. I picked the car up on 5/10/2025. I have a copy of the 4/29/2025 Service Report of the dealership.
