,am writing regarding a severe safety issue at the [XXX] Mitsubishi location. Over a month ago, I brought my 2004 Mitsubishi Endeavor in for an open federal safety recall regarding a fuel leak (the federal safety agency 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.

Had recall repaired (fuel injection pipe)@ pomoco hampton va. Immediately afterwards, engine light came on while driving 6 miles up the road. Five days later water started leaking on driver side only. Took vehicle back to dealer. They stated, a hose was missing on recall repair. I wondered why whenever I topped off gas @ the pump, fuel leaked from back tire area under vehicle. Fire hazard. They quoted 1500 to fix water leak. Got a it fix @ another auto repair. Six mths later, back to pomoco for yrly inspection, 2 days later, whenever I press brakes, make turns on city streets, highway, or in motion I feel something rolls under my feet but cant see it, must be underneath. A mth afterwards, everything is wet. All the floor boards, puddles. Cardboard, towels nothing will stop the water flow with AC functioning. I have 128,000 miles on the vehicle, bought in 2010 with 51,000 on it. Ever since the fuel pipe recall, that pomoco took 3 mths to complete because they didnt want to do the work which forced me to file complaint with the corporation, the federal safety agency, & one other, I've had water problems. This will be taken to a higher legal level due to this is & continues to cause harm, intentional or otherwise. We're advised here not to get personal but mold & mushrooms etc, should not exist in a vehicle. I see this has been an issue with lots of others and nothing done to date. Started in around oct 2015 (recall repair) & again may 2016.

Cold states include north dakota, south dakota, nebraska, kansas, oklahoma, colorado, wyoming, montana, idaho, washington, oregon, and utah. Adjoining states include arkansas, tennessee, and north carolina. In severe corrosive environments where road salts are frequently used in winter vehicles may be exposed to road debris (mud) mixed with road salt. This material can become trapped between a reinforcing bracket and the fuel filler pipe, potentially causing corrosion. Over time, corrosion could create a leak in the fuel filler pipe that could result in a fuel leakage when fueling the vehicle.
Risk
Fuel leakage, in the presence of an ignition source, could result in a fire.
Remedy

Recall number 10V065000 · Recall details

Fuel system, gasoline: storage: tank assemblyReported September 9, 2008 · 45,988 vehicles affected
What is wrong
Mitsubishi is recalling 45,988 my 2005-2007 endeavor, galant, eclipse coupe, and my 2007 eclipse spyder vehicles. The bracket that is the attachment point for the left rear fuel tank mounting strap may have been improperly formed during a metal stamping process. The process may have caused the metal to have a split in the area where the bolt that holds one of the two fuel tank straps to the underside of the vehicle is located. In the event the fuel tank is full and the vehicle is subject to a severe collision, the bracket may break and allow the fuel tank to drop down, possibly causing a fuel leak.
Risk
Fuel leakage in the presence of an ignition source could result in a fire.
Remedy
Dealers will inspect to see if the left rear fuel tank strap mounting bracket has splitting beyond a specific limit. Vehicles with moderate to severe splitting will be repaired using a reinforcement cap, a special structural adhesive, and a rivet to reinforce the fuel tank mounting bracket. The recall began on september 20, 2008. Owners may contact mitsubishi at 1‑800‑222‑0037.
