What owners say about the fuel/propulsion system
Verbatim from NHTSA complaints, newest first
“The fuel filler neck has an issue. When I refuel, I have to stop the pump manually or the filler cap will overflow. This creates a significant risk for fire or explosion unless I very carefully monitor how much fuel I am putting in the vehicle. I see several other owners experiencing this issue from online information I'm reading. I feel that this is an issue which should be repaired by the manufacturer.”
“I own the Jeep for 6 months now and at each fill up, fuel gets spit out of f the filler neck at the end. I try running slow, manual and the noses in different position. The jeep dealer say, there is no problem or recall for my VIN. But there is a recall part :(CNNNX321AC Tube) available form Mopar, there don't sell to the public. I like to fix this problem for more than one reason. Environmental, wasting Fuel, damaging the paint and plastic, fire hazard and fuel smell on my closes. I am a retired senior master Car technician, German (Kraftfahrzeug mechaniker Meister)with 50 years experience.”
“This has happened on more than 1 occasion. Driving on the highway and I lose power, the Jeep slows way down, the accelerator pedal is dead, and the Electronic Throttle Control (ETC) light comes on. It does the same thing driving in town. Sometimes you can turn the vehicle off, wait a couple minutes, start it back up and it will be ok for a little bit. Sometimes it won’t. I have replaced some parts, read forums, communicated with a dealer service department and it doesn’t sound like there is a “fix” for this. This is very dangerous and someone could get seriously injured or killed.”
“WHEN FUELING VEHICLE OVERFLOW POURS OUT OF THE TANK AND ON TO THE VEHICLE AND GROUND WHEN FILLED. I'VE OWNED THE VEHICLE FOR 14 MONTHS AND HAS BEEN DOING THIS SINCE PURCHASED.”
“GAS GOING ALL OVER THE PLACE AND ON ME. ALSO THE JEEP JERKS SO BAD THAT I ALMOST HIT MY HEAD. THE TRANSMISSON WAS CHANGED 30,000 MILES AGAIN AND RUNS LIKE CRAP.”
“GAS OVERSPILLS FROM THE TANK. DOES NOT AUTOMATICALLY STOP WHEN FILLING CAUSING GAS TO SPLASH ON THE OWNER, VEHICLE, AND GROUND. HAPPENS EVERY TIME WE ATTEMPT TO FILL THE TRUCK UNLESS WE MANUALLY STOP ENTERING GAS BEFORE IT'S FULL.”
