I purchased the car in 5/14/2013 after a week or so it started to lose power and misfiring , popping noise, transmission warms up. The gear that I hold and shift just warms up all the time it feels like it might fire up. Then I took the car to a mechanic they couldn't do anything. I took it to mazda mechanic they charged around 900$. Then it didn't fix anything I went another one and they told me loss compression it was 115 that time. I kept driving it and they said I need to rebuild the transmission too.. I paid this car 6500. And now it s all bad. And apparently I need to buy new engine and transmission. I believe it will cost me about 6000$ .now its on 129,000miles.

**resubmit-didn't go through** I was driving approx 65 MPH on the freeway and felt a kick/jolt and had a loss of power. My speed went down10-15 MPH and although I tried to accelerate it wouldn't do anything. I pulled over to the shoulder and tried to exit but car refused to go into gear. Every time I forced it into gear, the car would constantly stall and die. I had the ignition coil and spark plug replaced but now the clutch just sinks to the floor. I've tried to pump the clutch to get it into gear but this is quite dangerous on the road. My vehicle has trouble controlling its speed since there's a lag switching from 3rd to 4th, 5th to 6th since I have to pump my sunken clutch several times and fiddle with the shifter to actually kick my car into the next gear. My car is now over 100k miles and just read about the mazda rx8 clutch pedal recall online. This malfunction/safety issue was never announced professionally by my dealer. Mazda had no problems contacting me via phone, email ,mail regarding bills but for some reason failed to give me a notice regarding this defect. I've been advised that repairing this problem is quite expensive and since my car although less than 8 years old has passed the extended warranty based on mileage, I'll be stuck driving this car without proper repairs? I feel mazda should've contacted all rx8 owners to reduce the number any future disasters. Would there be any chance to extend the warranty for the clutch pedal based on mileage over 120k? I can't afford to purchase a new car at this moment but need to still commute to work without paying for repairs that would cost me an arm and a leg at the dealer? If this is a recall issue, I would feel more safe having an authorized dealer inspect the problem rather than a cheap auto shop that isn't fully aware of specific details.
