Selected complaints filed with NHTSA by 2004 Mitsubishi Endeavor owners, lightly cleaned up (personal details are redacted by NHTSA).

,am writing regarding a severe safety issue at the [redacted] Mitsubishi location. Over a month ago, I brought my 2004 Mitsubishi Endeavor in for an open federal safety recall regarding a fuel leak (NHTSA Recall 10V065000). I was sent away without a safe vehicle while parts were 'ordered.'Five days ago, the new service manager promised a callback the next day. I was ghosted. Today, I attempted to follow up on my parts status, and it appears the service desk has blocked my phone number. I am currently operating a vehicle that actively leaks raw gasoline at the pump in the Milwaukee area. This is a massive corporate liability.

Car would not start after pumping fuel in - took to mechanic; he said battery fine few days later, car would not start after pumping fuel in - took to mechanic; he said battery bad. I replaced battery. Few days later, car would not start after pumping fuel in - took to mechanic; he said new battery fine. Since car did not start 3 times in a row after pumping gas, and I needed a jump every time, I had mechanic do a diagnostic. He said the issue was tied to a recall bulletin. 10V065000 - filler pipe and cap. Called Mitsubishi to fix it but they said my car does not qualify because I am state of california. I do a lot of my driving in snow so I feel Mitsubishi should fix this for me. This is a potential fire hazard so I need to fix it asap (plus I don't want to get stuck at a gas station again needing a jump). …

Tl 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 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.

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 $850.00 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.
