Review on Mopar Part 52030377AB Fuel Filler by Scott Ramu

After spending hundreds of dollars fixing my 2011 Jeep Grand Cherokee to get through the smog just to get the check engine light back on, I finally have a little researched. jeep forums Find out that almost EVERYONE had the same problem with permanent codes P0456 and P0457 (thank goodness I have my own code reader, love that thing!). A simple and inexpensive fuel cap was the solution for most, so I thought it might be worth a try. Of course I changed the gas cap, the check engine light went out and never came on again. If I had just done my research last year, I could have saved SO AAAAAAA money. I wish my "trustworthy" mechanic would give me that advice, well, live and learn.
