Ignition Coils Failure Problems of 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.

1999 10th anniversary Mazda Miata currently with 33,900 miles on it. About 600 miles ago car suddenly started and ran rough with check engine light on. Had code checked and revealed p0300 (random misfire I. E. Ignition coil pack failure). Check engine light went out after reading code. Symptom reappeared recently with same code p0300. Replaced spark plug wires with ngk oem wires about a week ago and symptom reappeared this afternoon. I understood this is not covered by the emission control warranty but the subsequent catalytic converter failure is covered under the 8/80. 000 emission warranty. If the catalytic converter is subsequently caused by the failure of ignition coil then why is the ignition coil not covered under the emission warranty. This is another bureaucratic snafu. The cause of the emission failure is not covered under the emission control warranty. So maybe I should wait until the catalytic converter failed and have Mazda (Ford) replace the catalytic converter and then replace the ignition coil pack then because it will cost me the same but over $1000 for Mazda (Ford).

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.

1999 Mazda Miata had problem with ignition coils. The sensors indicated that there was a problem with the catalytic converter as well. Consumer is referencing complaint 10093484.
