10 Check Engine Light On problem of the 2004 Mazda RX8

Failure Date: 06/12/2006

I purchased my 2004 RX-8 in austin, texas, 8/19/03. My first problems occurred 2/18/04, pcm and coolant problems. On 3/29/04, I began having recurring problems with the check engine light. I also took my car for service for check engine light problems on 4/12/04, 3/3/06, 3/31/06, 4/3/06 and 4/5/06. On 7/19/04, I took my car for service because the driverã‚s-side sun visor fell apart. I took it in again on 7/29/04, for more sun visor problems. It is still loose. I took my car for recall services on 1116/04 and 9/1/05. On 7/1/05, I took in my car as it was running very roughly and dying. On 8/9/05, I again took in my car for check engine light problems and the fact that it was continuing to idle roughly and die. I took in my car on 9/1/05, because it was still idling very roughly and dying. On that occasion I was almost ã‚t-bonedã‚쳜 by another car that managed to swerve at the last moment. During this 22-day-long service visit, at 27,534 miles, my engine was replaced. I took my car for service on 5/22/06, because my car was idling very roughly and died 3 times on the highway. Each time I narrowly avoided being rear-ended by traffic behind me. This visit lasted 10 days. On 6/12/06, my car began idling very roughly and died 4 times. Again I narrowly avoided being hit by traffic. On 6/13/06, I took my car for service, where it remains, as of 6/16/06. On this site for 2004 RX-8's alone, there are 9 other complaints like mine. When I drive my car, I constantly fear the next instance when the car will die. Fortunately, I have escaped serious injury and serious damage to this point. However, I am certain that should this problem continue, as it surely will, that I will not continue to be so fortunate. Despite all my complaints Mazda continues to do nothing to remedy the problem. They need to buy back my vehicle, as it is quite obviously irreparable.

11 Check Engine Light On problem of the 2004 Mazda RX8

Failure Date: 11/07/2005

I received 2 safety recall notices on my Rx8. I took the car to the dealer where I leased the vehicle and I thought they corrected and/or inspected the problem. Over the course of the past 60 days, the service I have received has been unsatisfactory and I have been lead to believe that the dealer may not have addressed the safety recall issues. (cracked ball joint and heat insulation). I have a check engine light problem and I think they don't know what to do, to the point they will replace the engine. This will inevitably cause my vehicle to lose value.

2005 Mazda RX-8. Consumer states rough running, stalling and flooding. The consumer stated the vehicle became almost impossible to start.
