Hello everyone. I have a 2014 Limited Diesel and I absolutely love it. I recently though have been having some issues with it starting and the transmission being sluggish. I took it to the dealer and tgey said initially that the problem was common and could be fixed with a computer upload. Well upon further review, the service rep called me back and said theytested the fuel and found gasoline in the tank. Well this is absurd because gasoline was never put in the tank. They are telling me that I have to get my tank dropped, cleaned and flushed, and it will cost me over $700!!! Please tell me I am not the only one that has had this issue? Or am I? I repeat, I have never serviced my fuel tank with gasoline!!!

I have heard urban legends about the inept service guys filling the diesels with gasoline before sending the vehicle out to a new customer. Any chance that happened?

Well, glad to know I am not the only that dealer has tried to fleece on this one. So- first of all- I have a 14 GC Overland with 10k miles. Problems all started at about 5k miles- well documented MIL issues and after 6 trips finally got a cat converter. Jeep drove fine for about 150 miles then dreaded MIL back on. This time though code P1071- too lean bank one error code. take back to dealer who after a couple of days states- we checked your fuel with the "styrofoam" cup test and we think there is regular gas in the tank- I had the receipt from the last fillup and showed them- also got a sample from them. Fuel looked fine to me- took the sample to nearby lab for testing- 1100 dollars to drop/flush fuel tank and lines and filters- not covered by warranty of course. They called my wife and she okayed the repairs before talking with me. So OK- get the jeep and they left me with less than a gallon of gas after the repair so on the way home need to get diesel- I only go to high volume gas stations in order to try and get good diesel. anyway fill it up and not 50 miles later- MIL back on same code P1071. REALLY PO'd now- take back to dealer- get back to me one day later and low and behold- exact same diagnosis- 'Bad gas" and want another 1100 to fix- I tell them to p%ss up a rope and take the jeep home- Jeep has driven fine through it all- with absolutely no symptoms of gas in tank. waiting for appt at new dealership, one with an actual 3.0 certified mechanic. I am pursuing legal action pending test results.

One more thing- this 'styrofoam' cup test- I asked them how they did it and to show me the cup they used- It was a Sonic fast food drink cup- so I went to Sonic and got five cups- went to 5 different gas stations and got diesel samples from each- Low and behold- all 5 had diesel weaping through cup. A positive test for them. So as you can only imagine I am beyond frustrated, PO'd and all of the above. I am hoping that a new dealership can actually figure out what is going on- There is a new TSB from March #18-023-15 which states that pcm needs to be re-flashed and symptoms may include p0171 error code. Hoping this is the issue but who freakin knows. vaccuum leak, airflow sensor, continued DEF problems could be any of the above.

Just so everyone knows the dealer in question is on S Broadway in Denver, CO- I would stay away from them
