The gas tank release inside the car doesn't work.
First, we must determine which type of system is used. I believe that yours involves a mechanical latch. The gas tank release utilizes a cable mechanism that may have become stretched. A stretched cable cannot offer the same amount of tension to activate the mechanical release. In other cases, a faulty switch, or fuses, can prevent an electrical release from working properly. Have an experienced technician verify your gas tank release concern and estimate the repair. Consider our experts here at YourMechanic.
