I purchased a 2001 Mitsubishi Montero Sport used in March 2004, one month after purchase I brought it to the dealership with a complaint of a knocking noise in the engine. The dealership said nothing was wrong. I have properly maintained my vehicle since day one and learned to live with the knocking noise. On oct 23, 2005 the while driving down the highway the knocking noise became excessive so I pulled over, turned the engine off, waited a minute and restarted. As I started to accelerate there was a loud knock and smoke was coming from under the hood. Mitsubishi is claiming the vehicle threw a rod due to sludge in the engine. The are saying this was due to neglect of the vehicle due to the owner, although they have never once asked me for records of maintenance, which I have. They then say it was from neglect of the previous owner. …

Now after continuing to drive the car the tap got louder and the oil changes still remain as recommended. Without any reason or warning the motor started to knock louder, the oil light came on. Took the car back to the dealer and found out the knock was caused from the oil not getting to the top of the motor. Now at the dealership they told me that my car wasn't nor is the only one with the same issue. From 20 to 30 a month with the same issue.
