What can fail
On CNG-converted vehicles, the throttle cable may rub against and wear through the pressurized fuel line, creating a small leak. You may notice a strong natural gas smell or hissing sound inside the vehicle.
What the fix does
The dealer will secure the throttle cable away from the fuel line and inspect both components for wear, replacing them if necessary.
