This is a diesel. The wiring on the filter/water separator overheats and causes a fuel leak.

The fuel and water separator is leaking diesel fuel from the heater electrical lines. This is actually the second time this has occurred. The first time in 2008 the vehicle was idling when the wires began to smoke. Took it into repair the problem and didn't think anything of it. Now the same thing is happening again which upon further research have found this to be a common issue with the crd's. this car is a fire hazard not to mention the stalling and loss of power due to air being pumped into the fuel lines. My child is not safe driving this car.

Fuel was leaking out of the fuel filter head at the fuel heater electrical connection. The plastic around the fuel heater connecter had scorch marks. Vehicle stalled while pulling out of the garage due to air pulling into the fuel system through the electrical connection. Known issue for this vehicle type/model. Possible fire hazard and stalling potential. Have to replace the fuel filter head.

2005 Jeep Liberty diesel. Fuel/water separator leaks fuel through the heater electrical lines. Known fire hazard that Jeep/Chrysler has not recalled. Raw fuel runs out the live electrical heater lines. Engine was stalling on startup. Odbii code came on after a month of this "fuel leak severe". it was loosing prime while sitting due to air leaking in. Found fuel leak on pre-heater connector to fuel water separator housing. Found some burnt and melted plastic where connector was. I found numerous incidents of this on-line. I found a plethora of info on this and there weren't many of these vehicles sold. It seems like a serious issue. Chrysler obviously knows about their mistake, when I called them they were able to sell me a new separator with an updated fuel heater connection, fixing the known issue. With new separator, no issues. Should be recall. Stalling out on highway speeds and losing power. Could have been a serious accident. Chrysler techs couldn't fix the issue when I brought it in for repair and I spent over a $1000 on other repairs they thought were causing the issue before I found the info online about the separator issue and we found the melted heater connections.

2005 Jeep crd, fuel heater possible fire hazard. Design allows fuel filter head to melt then air enters the diesel system. Engine may stall on highway dangerous thing! mines stalled out and been towed couple times. Chrysler has been poor in fixing this problem. If fuel heater was to catch fire filter head and all fuel could burn to crisp in minutes. Maybe make chrylser offer lifetime warranty on these rare diesels. I can see huge lawsuits towards Chrysler if someone was to be killed stalling and or burning in vehicle.

Jeep Liberty crd. Engine was stalling on startup. Odb code came on after a month of this "fuel leak severe". it was loosing prime while sitting due to air leaking in. Found fuel leak on pre-heater connector to fuel water separator housing. Found some burnt plastic where connector was, clearly it got hot/fire. I found numerous incidents of this on-line. Considering there were reportedly less then 10,000 of these built, this is a serious issue.

Liberty Diesel

  • 86,000 miles
I have a 2005 Jeep Liberty crd diesel. I bought it used about six months ago at 56,000 mi. From a private owner. It now has 86,000 mi. I began having problems starting a week ago. The car starts and runs for 30 seconds and stalls. Then you cannot restart it. The starter spins the engine but it wont start. If you open the hood and pump the hand pump on the side of the fuel filter, which is mounted on the left fire wall, the car will eventually start and run. Yesterday, as I was pumping the fuel filter hand pump I noticed a drop of fuel come from the connector for the fuel heater on the spin on filter head. When I tried to start it, it started right up as it had before when I pumped the hand pump. As I walked around to shut the hood I could see the fuel dribbling out between the wires of the fuel heater plug on the head of the spin on filter. Halfway home I noticed a strong smell of diesel fuel, opened the hood and saw that the leak was getting worse because the plug was soaked in fuel and running thru the heater plug down the firewall. The dealer (tyson motors of joliet il) denies that there is any problem and said I will have to pay for the repair. I have gone to web sites and there are scores of people with the same dangerous condition with their vehicle. Many have caught on fire. So far I am told there is no recall. I guess there are not enough people dead yet.

2005 Jeep Liberty shorted out fuel heater caused a fire on the fuel and water separator which melted onto the wiring harness below causing the Jeep to stall immediately and filling the driver compartment with smoke. Could of caused a severe accident. Replacement parts are hard to find due to this seems to be a real problem with this vehicle.

Slow start was noted prior to incident (most likely due to air in the system). Jeep Liberty crd went into limp mode on highway causing vehicle to slow below 40 mph. Fuel/water separator was leaking fuel from pre-heater plug, which shorted out heater plug. Heater plug was scorched on the inside, no fire noted. Parts on order (approx cost $120 for part) intend to replace fuel/water separator assembly and heater plug wiring when it arrives. Old part will be available.

I, like many others, have a 2005 Jeep Liberty crd diesel. My fuel filter head is leaking fuel from the heater connector which could easily result in a fire. My connector is soaked in diesel fuel. Chrysler needs to be aware of this amd offer some course of action before someone gets hurt or killed.

Liberty 4WD 4-cyl Diesel

  • 26,000 miles
Car would start and die off after 1-2 minutes ( as in lack of fuel). There had also been electronic throttle control warning light flashing occasionally. To re-start, the fuel primer (located on filter head) had to be pumped. I read on www.lostkjs.com forum in the crd section that air might leak into the filter head, causing these symptoms. I noticed that the fuel heater plug located in the filter head was moist. I pulled the plug and heard a air-sucking sound. The plug contained a male part of what is obviously a burned-out fuel heater, which has made a hole into the filter head. A picture can be seen at the following link: www.pandkindustries.com/images/fuelheaterbusted.jpg I will be contacting the dealer and having the filter head replaced. The design is obviously faulty; any air collecting in the filter head leaves this heating element outside of the fuel allowing it to over-heat. Over-heating the fuel heating element can further warp/damage the already leaky filter head. Filter elements obviously will burn out over time. Apparently, these fuel heater elements are constantly activated. Air in the system can cause stalls at dangerous time (when accelerating and highway speeds. Worse, burning-out heater elements and fuel leaks could lead to fire!

  • Automatic transmission
  • 30,000 miles
Diesel fuel leaked out from around the electrical pins of the fuel heater. The failure was noticed as wetness around the connector during a routine changing of the fuel filter. Disconnecting the heater connector from the fuel filter head allowed several drops of fuel to escape. The fuel filter head was replaced by the dealer under the vehicle warranty and is not available.

2005 Jeep Liberty crd diesel engine started running sporadically. Smell of burning plastic and diesel was present inside vehicle. Pulled over and opened hood, to find boiling diesel steam coming from heater electrical port on fuel head. Plug was discolored with heat. Drove home, ordered new fuel head and replaced with new oem part. 2 months later, the engine started stumbling while driving on the highway and died on highway. Coasted to side of road, managed to eventually restart, and made it home. Opened hood and found leaking fuel head, from heater socket, diesel fuel draining from plug port at rate of about an oz per minute. Electrical plug was burned up, pins electrical pin on inside of fuel heater port destroyed.

The heater connector on the fuel filter housing has developed a significant fuel leak. This issue caused the vehicle to stop running at a traffic light in heavy traffic. I had to call for a tow. The tow truck guy hopped into the vehicle and turned the key to put in neutral so that he could load the vehicle. He left the key on and within a minute smoke was rolling out from under the hood. I thought the thing was going to catch on fire. I had no fire extinguisher (why would you need one for a new vehicle?). I jumped in the vehicle, turned off the key, popped the hood, and pulled the heater plug off (which was where all the smoke was coming from). Obviously, fuel leaking on electrical connectors (especially an electrical fuel heater component), doesn't make for a safe mix. This issue has already been reported to the NHTSA and has also been reported on various Jeep forums. This issue is a safety issue and should be addressed by the manufacturer.
