The 2004 Jeep Grand Cherokee has a fuel tank capacity of 20.5 gallons. This allows for a reasonable driving range, with an EPA estimated fuel economy of 14 MPG in the city and 19 MPG on the highway, yielding a combined average of 16 MPG.

Common Gas Tank Issues

Owners of the 2004 Jeep Grand Cherokee may encounter several common issues related to the gas tank:

  • Difficulty Filling the Tank: Some users report problems with the fuel pump shutting off prematurely while filling up. This can be caused by a restricted evaporative emissions (EVAP) system, leading to pressure build-up in the tank. To alleviate this, try adjusting the nozzle position during refueling or checking for blockages in the venting system.

  • Gas Smell: A noticeable gas smell can indicate a leak, which may originate from various sources such as cracked fuel lines, a faulty gas cap, or even a leaking fuel tank itself. Regular inspections of these components are crucial to ensure safety.

  • Fuel Gauge Inaccuracy: Some drivers have noted that their fuel gauge may not accurately reflect the actual fuel level, which can lead to unexpected empty tank situations. If this occurs, it may require professional assessment of the gauge and associated wiring.

  • Regularly inspect the gas cap to ensure it is secure and free from damage.

  • Check fuel lines for signs of wear or leaks. Replace any damaged sections promptly to avoid fuel loss and potential hazards.
