Example complaints

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

“I was driving my 2002 Mitsubishi Montero limited through town when out of the blue, the loudest noise started coming from the front of the engine. You could hear the noise from blocks down the road. Took it to a local mechanic who discovered a technical service bulletin that states, some vehicles may experience a dieseling-type noise when the engine is idling. This may be due to the piston pins contacting the cylinders. Inspect the cylinders walls for evidence of scuffing. …”

“This car have a lot of problem that the dealer cannot resolved or fix, it first started on nov 15,2002 when the car stalled when on idle. I called the dealer the next day nov 16,2002 and address the problem, but they told me if the same problem happen, bring it to the nearest dealer. On january 1, 2003 the car stalls again and the check engine light is on, on january 2,2003 I went to the dealer and they diagnosed the car and they told me the problem is misfire and they reset the lights and adjust the idle. …”

“I'm experiencing 'again' engine vibrations while at idle. The speedometer needle starts to go down to 0, engine vibrates, appears that it will stall, and just in the nick of time before the needle hits 0, the needle returns to idle and all is ok. Ok???? I don't understand this vehicle and neither does the dealer. Last time I took the vehicle for service (11/3/03) they changed spark plugs, gasket and inlet manifold both sides. I'm taking it to the dealer on tomorrow (the day after the incident) and if they can't fit it I'm getting a v8 ford.”

“Our 2002 Mitsubishi Montero engine blew up while my wife was driving the vehicle on a local highway (rt. 680(n)). There was no indication that there was something wrong with the vehicle prior to that day (the check engine warning light had never lit up). At the time this instance occurred, my wife was driving the vehicle on the freeway as it went up in smoke, essentially endangering her life along with the surrounding motorists, should this really happen to a vehicle that is only 5 years old.”

NHTSA complaint #10214454, filed 2008-01

“Engine vibrates when at idle, and acts as if it may stall, but does not. Took the car to the dealer and dealer said idle was too low. But a week later, engine vibrated again and appeared it was going to stall but did not. I called Mitsubishi reps in california, they came down to florida to test my car. For three days they kept it and said they fixed the problem: they changed the spark plugs and cables and told me to use premium fuel from amoco. A week later the car vibrated again and appeared it would stall but it did not. …”
