On at least 3-5 occasions this 2.0l engine has suffered the exact same fate as the federal safety agency id# 10422484. Check engine light on, misfiring, associated noise sounding like a bolt / screw bouncing around in the engine for maybe 15 seconds, then would return to normal. Each time there has been a different cylinder misfire, upon spark plug removal it was found the gap was closed causing no spark. Each time, a new plug was installed and corrected the immediate problem. After seeing these complaints and a recall regarding this issue I realized I've had the same issue. Don't know if my VIN # is in the effected range or not. Car now has 123105 miles. Would hope that mazda would cover any vehicle with this problem.

The car began to shutter and dropped from 50 to 25 in seconds. The check engine light (cil) starting flashing and the car began to stutter like it was going to die, I pulled to the side of the road and the car died. Started car again the cil continued to flash, it only would accelerate to 25 miles an hours even with my foot all the way down on the gas. I took it to the a mechanic and the codes were p0421, 171, 300. The mechanic did everything from engine flush, spark plugs, oil, air filters and installed a new catalytic converter but the problem persists. Its now a year later and the car is doing the exact same thing.

While driving on highway at about 60 MPH for 40 minutes, the car began sputtering, jerking, making noises, losing acceleration and the check engine light came on. It initially felt like someone was taking their foot on and off the gas. We pulled off road and were towed to our garage. Mechanic found that the spark plug for cylinder 4 was smashed shut, he replaced it and told us to take it to the dealer since this was the 3rd time we had this problem. In dec of 2009 the spark plug for cylinder 1 had same problem then again in feb 2010 it was the plugs for 1 & 4. Each time we were driving at 55 MPH or higher when car began to sputter then check engine light came on. Mazda is telling us nothing is in the engine, the compression is fine and they have no idea why spark plugs are getting smashed. The first time it happened our mechanic thought it was bad spark plug and replaced it free of charge, the second time we took it to the dealer who could find nothing. It is now at the dealer again and they are saying the only thing they could do is take the engine apart and look but have no guarantee of finding anything and it could cost $1500. They removed spark plug, checked for debris and tested the compression. They also used a magnet to search for foreign body in cylinder and found nothing.

While driving to work my car began to shudder and hiccup. Then the engine light cam on so I pulled off the highway. I started it back up and the car had a more serious shudder. I got it to a local service station and they ran a computer diagnostic and said it was a misfire in the #4 cylinder. The sparkplug was smashed. Nothing was found in the cylinder so the sparkplug was replaced and temporarily fixed the problem. Two weeks later the same shudder problem and again the engine light came on. This time the #1 cylinder was the problem and again with the same smashed sparkplug. My mechanic thought it was a very odd occurrence and checked and found the recall #3005c. My local mazda dealer then said my VIN# did not fall within the range of the recall and yet there seems to be many people with this problem. It looks like mazda is trying to avoid this problem.
