Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Over the last 4-6 months I noticed a gasoline odor after filling the gas tank (affected part). The gas odor has gotten significantly stronger outside and inside the vehicle each month. If I fill the gas tank today there is an extreme gas odor/fume that is leaking from the gas tank. As the gas tank empties the odor decreases. There isn't a gas liquid leakage that you would see on the ground, but a flume leakage that fills the passenger compartment and surrounds the outside rear area of the vehicle. …”

“Heavy smell of gasoline when fuel tank is filled. Fill garage with fumes. Check engine light is on. If filled to a half tank or so, no indication of fuel smell. Does not appear to be leaking. I had an ase certified mechanic look at it and the fuel tank as well as filler nozzle are deteriorated. I called Mitsubishi motors north america and they acted as if this was the first time they ever heard of this problem. I called multiple dealers, and all have experienced the same problem with their customers. The inter-net is full of similar complaints on 2003 to 2006 outlanders. …”

“The vehicle is was purchased used with no check engine light on at the time of purchase. After driving for a week the light came on and there was a strong fuel smell after filling the gas tank. A diagnosis check was done and it was found there is an issue with the fuel tank. It was brought to the dealership and found that there is a hole in the top of the gas tank causing fumes to leak. The tank cannot go below a quarter tank or the engine will shut off as well. After researching through the internet it was found that this is a very common problem with the vehicle. …”

“When I bought my car some time last year everything seemed fine but after a few months things started to go wrong on the car. It began with me constantly having to get the oil changed the tires were bad the car started making noises that I couldn't explain and the tires in the tires in the back were constantly busting. The engine is now going bad and I have bought at least 10 sets of tires for the back in this year alone. I don't have the money to keep putting in this car and continue to pay the lease off for it as well. Its getting absolutely ridiculous.”
