Mazda RX-8 Problem

Me Too

Model Years Affected: 2004, 2005, 2006, 2007, 2008

Average Mileage: 81,487 mi (30,000 mi - 148,000 mi)


Hesitation and/or a lack of power can be caused by the secondary shutter valve (SSV) in the intake manifold becoming stuck open due to carbon build up around the SSV shaft. This may occur with no Check Engine light illumination but eventually the light will illuminate with code P2070 (Secondary Shutter Valve [SSV] stuck open). The cleaning procedure described under the service bulletin is a long process and it is recommended to install the updated SSV actuator and gaskets. The SSV is activated at higher RPM and the carbon accumulation can happen when it opens infrequently. The effects RX-8's built before April 18, 2007.

    Car hesitates will not pull without stepping on the gas. Performance has dropped greatly. Not fixed was told it would cost over $800.

    Hesitation is occurring when starting and does take more attempts to get started in the morning. It does seem to stutter when I'm out of gear and is okay when in gear.. My dealer doesn't offer to clean it, but says must replace it for $800 or so? Wondering what the prices were for those who had it cleaned instead as this seems to be an option.

    Lack of power from 4000rpm to 5500, diagnosed as SSV stucking shut (!). After cleaning no power loss and hesitating in that range.

    I have had my car towed to a dealer 3 times and a Repair shop once. Each time the car engine would turn over, but not start. The engine was found to be flooded and excess gasoline was cleaned out. Battery and plugs replaced 2 times. The first time it happened, the dealer replaced SVV Valve with associated componets. Bulletin 01-019/08.
