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.

After driving my 2004 Mitsubishi Endeavor over the past few years I had a gas leak that I thought was stranger while fueling my SUV. It turned out to fall under the recall for my SUV. I had this problem long before the recall was issued.lord only knows how much gas I lost at the pump that I will never get back... but I recently had a problem with my front rotors I had a Mitsubishi dealer inspect my entire SUV for any and everything else that could be wrong..just the other day I went to stop at a red signal and my SUV did brake but only for a second it started to slide forward as I lost braking power in my front brakes I heard a big pop and a clank as I applied my brakes and halfway slid through the light after the light turned green I drove a ways down the road and was hearing the clank sound and it felt as if the front tires were trying to catch on something I thought it might have been the calibers or the brake pads. I pulled into the closest gas station to see what had happened. The pads were fine the tires were fine and everything looked ok no brakes fluid leaking the calibers were fine... I slowly drove/coasted my SUV to a friend's home going about five to ten miles an hour. I took off the driver side front tire to see if indeed it was the brake pads or calibers as I was taking off the tire I noticed that the rotor had split in half. Like separating two plates at that point I called a licensed mechanic and he stated it sound like a defect in the rotors Iżve had these rotors on the SUV since Iżve had it and it was checked out by a dealers service center before this had happened. I wondered since my SUV had to go through the recall of the fuel filler for SUV in the North for salt and snow that would corroded my fuel filler would it be the same for the rotors if they were to have a special kind of rotors for my SUV used in the North during winter, I was told it was a good thing I hadn't been traveling at higher rate of speed it could have been worse.

The contact owns a 2004 Mitsubishi Endeavor. The vehicle was included in the recall associated with NHTSA campaign id number 10V065000 (fuel system, gasoline: Storage: Tank assembly: Filler pipe and cap). The vehicle was taken to an authorized dealer where the contact was told the vehicle was fine and did not need to be repaired. The vehicle was not repaired. Approximately 1 week later, the check engine light began illuminating on the instrument panel. The vehicle was taken to an independent mechanic where the contact was told there was a hole within the fuel filler pipe. The vehicle was taken back to the authorized dealer where the contact was told the fuel filler pipe was severely corroded but the hole was in the fuel tank, not the fuel filler pipe. The vehicle was repaired but not under the recall. The failure continued. The failure and current mileages were 134,429.

I received a safety recall on my 2004 Mitsubishi Endeavor, about the fuel filler pipe might become corroded from road salt in cold weather. That's fine about the recall but the problem I have is the dealership in lynchburg, va. Closed up and I was not made aware of this from anyone. Now the problem is they say I have to take it to blacksburg, charlottetsville or somewhere else, the problem with that is these places are one hour to two hours away from me and I want to know as a loyal customer who is going to pay for my gas and time to get this issue resolved. This is not good customer relations to close up shop and not let the consumer know what has happened and what to do in cases of a recall, that makes consumers highly upset and will not buy another Mitsubishi again. I don't have the time or money to spend in gas to drive two hours away to get a recall taken care of. Seems like some place close to me could take care of it and they can bill the Mitsubishi place. This putting the consumer out of the way. And what would the consumer do if it was something major that happened. This is so upsetting that I would like to take this to my local news and complain.

Mitsubishi Endeavor 2004 fuel tank fill-up hose (sill hose) has hole - causing fuel leak when filling up the gas tank. It also cause the service light to turn on due to the holes in fuel hose. Dealer wants $600 for replacing the sill fuel hose. However, I feel it is not right, as its only 5 years old vehicle. I checked the part department to find out how much it cost to replace. The service tech told me that they have to order 6 more same parts for other customers for the same problem. It reminds me of Ford pinto - which can be very explosive when rear-collision-ed. Please advise, as I believe this kind of problem deserves a serious safety recall.

Fuel filler neck leaking gas and filler neck & clamp defective on a 2004 Mitsubishi Endeavor AWD. The "service engine soon" light came on 08/27/2009 and the SUV was immediately taken to the rt 112 Mitsubishi dealer in medford NY. The dealer checked & found code P0456 stored. Cleared code and charged $98. The light came on again few days after. Informed dealer about problem. Took the SUV back to dealer on 09/22 and they did another test and found code P0442, small evap leak. Replaced gas cap for $48.57. Took the SUV to motorworld group in wilkes barre, pa for pa state inspection and it failed the safety inspection. The pa dealership said "fuel filler neck leaking gas and needs to be replaced." Total cost $610($265 for parts & balance for 4 hours labor). The service advisor said that they experienced the same problem on the Mitsubishi montero models. Apparently the manufacturer did not bother to correct this defect at the detriment of the buyers, paying hefty repair bills for their own profit. Please investigate and contact us soon.

The fuel filler tube on my 2004 Mitsubishi Endeavor rusted out resulting in fuel leaking out whenever I filled the tank. The fuel filler tube has a coverplate in pne section to protect it from being damaged. Wet dirt and debris collected in this coverplate due to normal driving, resulting in the fuel filler tube rusting out where it was covered with wet dirt and debris. The Mitsubishi dealer repaired the rusted tube by totally replacing it at a cost of $850 that I had to pay. This part was approximately 5 years old when it had to be replaced. I have pictures of the rusted tube and coverplate that I can provide. This is a major safety and environmental exposure for Endeavor owners and also an expensive repair for a part you would expect to last the lifetime of the vehicle.
