The contact's girlfriend owns a 2007 Jeep Wrangler. The contact stated while refueling the vehicle, gasoline would spew out of the fuel filler neck. The dealer was made aware of the failure but informed the contact that there was no recall associated with the VIN and that the vehicle was out of warranty. The manufacturer was made aware of the failure but informed the contact that the vehicle was out of warranty. The vehicle was not repaired. The failure mileage was approximately 130,000.
I bought my 2007 Jeep Wrangler in November 2020. It had approximately 122,000 miles on it and has the 6 speed manual transmission. After driving it for 7 days, I was backing out of a parking spot and heard a loud squeal and was unable to shift gears. It had to have the clutch replaced along with the flywheel and several other clutch associated parts. The total was $1,600. The salesman at the dealership where I bought it told me as I was buying it that there is no warranty but if something happens in the first couple of weeks that he would work with us. Of course he did NOT help me. He wouldn't even return my phone calls. Whatever, buyer beware! Second issue is of course the fuel spit back problem. Every time I fill up, I end up with gas on the Jeep and on the ground. I love wasting money like that. …
Fuel back flow when filling up. Well documented by other owners.. certain other vin # s have had recalls and repaired Dealership parts department claimed no knowledge of inexpensive part replacement /addition of check valve in filler hose section to prevent back flow and flammable gasoline spillage while fueling. $40 dollar part? Part # CNNNX321AC ?? YouTube videos and Jeep Wrangler forum.full of the issue. Predates my vehicle I know Many people have shared that 2006 wranglers had the same issue.
Service Bulletin # 14-001-11, dated February 11, 2011 built between March 1, 2007 March 31, 2008 recall on inlet check valve recall. My vehicle was built 08/2006 and does not fall within the dated window however it is experiencing the issue. Gas overflow is not only a cost of money but also a danger to the environment. I am asking for an extension on this recall to include my manufactured year.
Fuel spits out during filling so you have to barely squeeze the pump handle. It takes a long time to just put 20.00 in gas in it sometimes as long as 5 mins. When you live in a cold weather state it becomes an issue when you try to pump it and get splashed with gas because you are trying to get out of the cold. Seems like this would be a health hazard along with a fueling problem.
In 2022, I paid over $15,000 to an official Jeep dealership (Chrysler Dodge Jeep RAM City, Greenwich CT) to replace the engine in my Jeep Wrangler. Without clear disclosure or consent, they installed a non-OEM Jasper remanufactured engine. The invoice misleadingly stated "ALL PARTS ARE NEW UNLESS OTHERWISE INDICATED," with no mention of Jasper or warranty terms. The vehicle began malfunctioning almost immediately, raising multiple serious safety concerns, confirmed by written service exchanges: "The Jeep is stopping alone! Just crazy, brakes come on alone" - Spontaneous brake engagement poses a serious crash risk. "It also smells strong gas when turning the car on" - Potential fuel leak or misfire, which is a fire hazard. …
This vehicle frequently experiences fuel "spit-back" on filling. It was manufactured in 10/06, five months before the date in Jeep's lifetime fuel tank replacement extended guaranty for spit-back. Also, the tank began leaking after every fill up. It leaked on the ground and/or with gas fumes present until the tank level got below 1/2 tank the leak source was where the fuel pump is inserted into the top of tank. The iron clamps and lock ring for the fuel pump are located in a depressed "bowl" at the top of the tank. Water accumulates and remains in the bowl causing the lock ring and clamps to rust. The rust expands and cracks the plastic that the fuel pump is made of. The repair requires replacing the fuel tank, lock ring, and fuel pump. In my opinion, this is a design or manufacturing problem and these conditions cause serious environmental and safety problems. …
For the past 5 months I've had my check engine light on. I read the code and is says "large e vap leak " I've replaced the pcv valve and the e vap charcoal canister and the check engine light is still on. I've brought it to a mechanic and they did a smoke test and everything tested out good. Showing that there were no problems and to start with the gas cap. I've spent over 100.dollars on gas caps and I still have the problem. I have to for emissions by the end of December. I've had every recall known to man on this Jeep. I've done research and found out that it could be the gas filler neck itself. How to I go about getting a new one and will it cost me anything? I also have problems when I try and fill the tank. The gas comes flying back out if I try and fill it. Its getting out of hand and the dealership won't give me an answer. …
Purchased 2007 Jeep Wrangler in 2015 and have had problems with fuel splashing from gas tank when filling up. This should not happen. Fuel should stop once tank is full. I have noticed this is a problem with many Jeep Wrangler (jk) owners and would like to know if a recall is in effect or how it can be fixed. Bottom line I have called several dealers inquiring about part cnnnx321ac, which is a recall part #, but they can't sell it to me. So, if I can't buy the part to fix and they have no recall on the car, is my only option at this point to sue the Chrysler corporation? This is a car my daughter drives and it is a safety issue not just some superficial issue with Jeep. This occurs every time she goes to the gas station to fill the Jeep. Smelling like petroleum after every filling of tank is not the right answer.
Fuel spills out of fuel tankl filling port after fuel dispensing equipment automatically stops. Fuel dispensing pump safety feathers incompatible with Jeep gas tank fuel filling design.this presents dangerous conditions and environmental concern with every fuel fill up regardless of gas station ran or equipment. It's almost as if fuel vilume greatly increases after gas dispenser stops fueling. More then a quarter gallon of fuel is spilled on my vehicle all over it every time I fill my vihicle,hot breaking system components and exhaust components coming in contact with liquid fuel,.forums and internet searches reflect that this problem exists on all vehicles with this fuel system design.situation captured in this video: https://youtu.be/zouvokeolo8
