Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: Poor side crash test ratings from the IIHS are really no surprise.

2012 Jeep Wrangler Owner Comments

While being towed by our rv on a city street, a fire started under the hood of the Jeep. The transfer case was in neutral. The manual transmission was in neutral. The ignition switch was turned 1 notch to accessory to unlock the steering. The fire was extinguished by the fire department. No police report was filed because the fire was not caused by an accident. Because of the severity of the fire damage, no cause of the fire was determined.

I bought this Wrangler on 5-30-2015. The first time I took it to fill up the gas tank, I was exposed to the fact that the tank does not shut off and overflows all over the Jeep (and me). This has happened everytime we go to fill up, to where we have to watch the fuel level on the instrument panel to make sure it does not get all the way to full. This indeed happened again just a week ago Sunday when we went to fill up and I was speaking with a gentlemen who had just bought his Jeep and I was talking to him about his and if he has had issue with his gas tank overflowing. As I was talking to him yep, you guessed it, it overflowed. Now, I read today that Chrysler has said that it has to do with the type of fuel you put into the tank"? really??? so I have put in anywhere from 85, 87, 90, and higher grade fuels, and it still happens? next are they going to say it is the gas station company I go to? the way I put the nozzle into the tank? (does this sounds sarcastic when you read it" good) I find that comment from Chrysler absolutely demeaning and idiotic!!! it has been a known issue on several previous models of Jeep, but for some reason they are going to ignore this one" what will it take Chrysler? will it take a class action lawsuit to get your company to fix the problem? I now just read a reply that someone had contacted a law firm in regards to a class action suit and that it had been transferred to bankruptcy court in New York where it was still alive and that the court had granted Chrysler's motion to dismiss stating they are barred by the sale order between bankrupt Chrysler and the new Chrysler. Wow!!! great business model. Lets file bk. (one of the questions asked at the bottom of this complaint form is when did this happen" every time I fill up since 5-30-2015!!!

When filling the gas tank, once it reaches the full point, it fails to trigger the fuel pump to stop in time and fuel spills all over the side of the rear fender. It does this every single time I fill up.

Vehicle engine light came on after starting engine and driving 30 feet from initial parked location. Vehicle was stopped and explosion occurred under the hood while driver was still in vehicle. No previous indication there was any issue with vehicle. Upon driver emergency exit of vehicle, further explosions and large flames engulfed the vehicle resulting in a total loss of vehicle within minutes.

Gas spills out of the gas tank when filling up. Happens at different gas stations, both with the handle clipped in the pump position and also when gripped by hand throughout. Very dangerous as it has gotten on my hands and clothes and all over the car. Very flammable situation.

Update to complaint number 10692609 regarding the check engine light and codes P0441 and P0445. A new mopar gas cap has taken care of the problem. Two after market gas caps, purchased new, were faulty right out of the box. The new mopar gas cap has cleared the codes. Apparently not all gas caps are vehicle specific...

I recently bought this vehicle as a used car. The fuel overflow valve does not work causing gas to spill out onto the car and ground every time I fill up the car. This is obviously an environmental and fire hazard. The Jeep internet forums are full of postings of the same issue with several Wrangler models and years and the recommendation is to replace the filler tube containing the check valve. It is obvious that this is a defective part and the manufacturer should issue a recall and repair the problem for free.

When adding fuel to the vehicle, after the initial pump shutoff when removing the pump from the fuel inlet, the gasoline come back out under pressure and soaks the operator. This has happened consistently since the initial episode. It makes no difference whether the fuel is pumped slowly or fast. This vehicle has been returned to a dealer for inspection. No immediate cause has been found.

The contact owns a 2012 Jeep Wrangler. The contact stated that an extremely strong odor of gasoline emitted inside and outside of the vehicle continuously. The vehicle was taken to an authorized dealer for diagnosis. The manufacturer was not notified of the problem. The approximate failure mileage was 3,000. The VIN was unavailable.

When you fill the gas tank, there is always a spill over of gas that comes out. I have researched this and it is a very common issue with Jeep owners. Please force a recall. It is very dangerous to have fuel all over the side of the car and on the floor every time I fill up for gas.

I was driving in 4 low in 90 degree and 3000 feet elevation gain. I could smell a strong gas vapor. It was in the cab and outside. It is due to the design of the evap system. The jkdepends on a spring valve to relieve excessive pressure/vacuum in the fuel system. The esim is a crude device meant to meet monitoring requirements. The reality is on hot day when vapors are prevalant, especially in 4WD low when the vehicle is moving slow and the engine are high revs are high you may smell fuel. This really bothered me with my family on board.
