Ignition Coils Failure problems of the 2000 Mazda Miata

Engine began running badly and check engine light came on. Took to Mazda dealer shop and was told a spark plug wire was defective and burned up. In actuality, the ignition coil had failed and caused the problems. The dealer replaced spark plugs, ignition wires, and coil. Two months later the check engine light came on again and the catalytic converter was clogged and had to be replaced. The mechanic said it was due to the poor running during the time when the ignition coil had been misfiring. So the defective coil caused a great deal of damage, and Mazda has taken no responsibility for these defective parts or the damage they have caused. If you read complaints for 1999 models, you'll see many failures of the ignition coil, some causing damage to other parts costing a great deal of money. Apparently, similar coils were used on 2000's with similar failures. But no recall and no investigation.

I paid a total of $835. 03 in repairs due to unqualified Mazda technicians and inferior parts (ignition coil) that Mazda knowingly installed in the 1999 and 2000 Miata?s. In may 2004 my engine light went on. I had the spark plugs and spark plug wires checked to determine if that was the problem and they were fine. I called the dealership and explained the situation and brought the Miata in for service. I was informed by the service department that there was a p0300 code (random misfire ) and that the spark plugs and spark plug wires needed to be changed. I told the service consultant that the plugs and wires were already visually inspected and deemed to be in working order. He insisted the plugs and wires were the issue and performed a tune-up for 322. 24. I had to bring the vehicle in three more times because the engine light continued to go on. Finally in December 2004 they concluded it was the ignition coil and I was told it would be an additional 512. 79 to correct. When I asked if they can do something about the price considering they misdiagnosed it the first time, their response was ?you need a tune-up at 30,000 miles any?. First of all when I got the tune-up in may there were only 23k miles on the car (I still don?t have 30k miles on it). Second of all if I was told a tune-up was not going to correct the problem I never would have agreed to getting one. I?ve recently discovered that the ignition coil is a known problem on the '99 and '00 Miata that Mazda refuses to address. Since this is a known issue, the dealership should have inspected the ignition coil when the vehicle was first brought in and it should be a recall issue. No old parts are available.
