2015 Jeep Wrangler fuel system problems

Filed Oct 30, 2026 · Fuel system · CO

We have been experiencing an intermittent gas leak for two years. We have taken it to AutoNation Jeep several times for this issue but they haven’t been able to reproduce the problem. We have provided video evidence and opened a case with Jeep, Case XXX, but nothing has happened for two months now. We have a lifetime warranty on the Jeep and have asked that they replace all possible parts. Jeep approved this but the dealership refuses to do the work. We are left with an unsafe vehicle that leaks gas. If you go through this video frame by frame you will see the gas on the undercarriage. I did not trace it to the source, but you can clearly see the gasoline traveling and then dripping onto the ground. I had driven the car maybe 50 ft up my driveway when I smelled the gasoline and got out to film. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have been working with multiple mechanics to diagnose an intermittent and unpredictable stalling issue with my 2015 Jeep Wrangler JK Rubicon Unlimited, VIN [XXX] . I have conducted the following repairs to attempt to fix the issue: 1. Rebuilt Transmission 2. Replaced throttle body 3. Replaced PCV 4. Replaced crankshaft sensor 5. Replaced camshaft sensor 6. Replaced Fuel Pump 7. Replaced fuel pump fuse 8. Replaced fuel pump relay fuse Mechanic and I have traced the problem to a likely fault in the TIPM. Due to unpredictability of stalling this has become a safety issue as the car will stall in traffic. Most often between 35-40 mph and below 2000 RPM...this is always while driving and is unsafe for both me and my fellow motorists. Most recent date is noted later in this form. If requested, I can provide receipts for professional repairs noted above, and receipts for parts I have purchased to replace myself.

I have experience a complete loss of control of the vehicle on both highways and streets that are bumpy due to dips, potholes, rough conditions due to the road. I received a misfire on cylinder 4 code P0304 and was told my vehicle isn’t covered for any recalls, but see that this is a common issue in 2013, 2014, 2015, and 2017 models. I want to know if any recalls or lawsuits are going on because my dealership informed me there aren’t any and it would take a week to even be able to diagnose the issue.

While driving, the vehicle loses propulsion; the rpms go to zero for about 3 seconds and then return to normal and acceleration is regained. No check engine light or code is given. This occurred randomly for the last year. In june of 2020 I took it to jeep dealer who was not able to replicate the problem and said that no code was given. Then in december of 2020 the issue became worse to where the vehicle would completely shut down and not regain power unless restarted. On one occasion it would not restart, leaving me stranded. I took it to an independent mechanic who also could not replicate the problem. The independent mechanic suggested that the symptoms sound like they are related to a fuel pump relay, but that part is not replaceable on my jeep. They said that other chrysler vehicles have had recalls for similar problems, but not my year model jeep. The problem continues to persist randomly. Sometimes it happens twice within an hour, sometimes not at all. When it happens it's always in motion. On january 16th I video recorded the incident while driving. I have the entire thing on video that I can share with you. In the video you can see that I'm driving at a steady speed at 2500 rpms. Then the rpms flash quickly to 3500 rpms and then instantly drop to zero, as though the ignition had been turned off. Although I still have electrical, as my radio and blinkers are working, the jeep very quickly loses power steering. If I had not been able to quickly pull off the highway my jeep would have been dead and stranded in the middle of a busy highway. I then attempted to restart the jeep, but it would not start. I would turn the key just once and let go, but the jeep would continue trying to start over and over for about 10 seconds before stopping. I was unable to start the jeep until waiting for a period of about 10 minutes. Then it started up and operated normally.

While driving the jeep shuts off. It is hard to steer and happens without warning. This has happened about 10 times in the last month. It does not throw a code so the dealer can not fix it.

Immediately after completing work from the air bag recall my vehicle began to accelerate on its own. I would hold a steady throttle and it would all of a sudden speed up. It would last for a few to several seconds and slow down to a point less than the steady throttle. When I would use cruise control the vehicle would vary in speed by five to seven miles per hour. This was definitely a change from the way it operated prior to the recall. I used injector cleaner through several tanks, but the problem persisted. The condition was limited to depressing the accelerator, but has worsened to the point of revving the engine with the clutch depressed and no pressure on the accelerator. I had to cut the engine off due to this uncontrollable rev. I contacted the dealership to inquiry of any such issues following the air bag recall, but before I could complete my question, I was told, "no." maybe, this issue is coincidence, but it is truly a safety concern. I have searched the net for similar incidents, and it does not appear to be very prevalent. The vehicle currently has just over 68k miles, and zero incidents/problems prior to the airbag recall. I believe the steering wheel is removed when the airbag issue is corrected, and for this reason I question if the issues are unintentionally related.

Twice, end of may 2019 and february of 2020 I had scheduled oil changes done at same dealer. By the end of those days, jeep would not run, check engine light blinking and would barely start, not run. Both times towed back to dealership, both times under warranty. First time I was told a broken valve spring and valve cover had leaked oil into ignition system. Valve spring/cover work covered, tune up and redoing ignition system not...? Was told to contact manufacturer, they told me to contact dealer. This time(2/2020) towed in, took six days to be told broken valve spring/valve cover but also a defective cylinder head. Also told cylinder head on back order, could be months. Vehicle is maintained according to manufacturers schedules, don't do tractor pulling with it, this appears to be a known defective, just like the bad radiators or heating system gooped up with sand. Thank you.

My jeep caught fire while driving on highway due to a ruptured fuel line spewing fuel onto the nearby passenger side exhaust manifold. When I exited the vehicle, a fluid was on fire dripping down from below the fuel tank. After a few minutes, the fire got to the engine bay and melted all things plastic. I went to the salvage yard the next day to see what could have caused the fire and noticed that the fuel lines were gone. Upon comparing them with another jeep wrangler jku with automatic transmission, it appears that there are two plastic-like lines show the potential of rubbing together and causing the lines to eventually rub open. With the exhaust manifold just a few inches away, this is a real potential danger to the occupants of the vehicle.

Fuel blow back when filling it, at various gas stations. Not able to fill at normal rate. I hear from many people that this is a known problem with jeeps. It is a safety issue. It could be their ball in cage filter design, or o ring gaskets.
