general problems of the 2007 Mazda MAZDA3

My vehicle felt shaky which caused me to swerve slightly causing my back passenger tire to run over a curb. After the scare it seemed to drive like normal. I only had about a 5 minute drive to work. When getting to work, after being inside a few minutes, a coworker pointed out that smoke was coming from the car. I went with a coworker to check, we opened the hood and flames were present in the front close to where the belts are. We quickly put out the flames with a fire extinguisher, and I have not touched the vehicle. This happened on 5/03/19.

Fuel propulsion system cracked at coupling under the rear passenger seat spewing massive amounts of fuel into the cab soaking the rear seat pad fire risk present with electric plug there struts are unstable and noisy vvt makes noise when started, grinding in front hubs. Vehicle has some of these problems driving and parked. Airbags system non active. Other issues unknown but possible 35.

The check engine light came on. Cause ,after running code check,p2004. Runner control vale stuck. Replace solenoid. Front struts gone.

Vehicle was travelling along on 30 mph road with 'stop' sign ahead. As vehicle slowed down to about 15 mph, transmission started to shake, several warning lights came on and off, including oil and power steering, rpm fell very close to 0 (zero) and car died. Vehicle was able to stop at the 'stop' sign. Even though the vehicle was still on, any pressure on the gas pedal did not provide power or input to the transmission, now in 1st gear, to move the car. Car needed to be completely turned off and then turned on before it could move again. This issue has been ongoing for 4 years regardless of speed. The car has also decided to stop providing power while in motion while in moving traffic or on the highway, which could have resulted in multiple car crashes or worse. Mazda refuses to aknoledge that anything is wrong with the car since they "cannot replicate the problem". This issue is sporadic and occurs regardless of speed (usually around 30 mpg or less), weather, distance travelled, amount of time car has been in consistent use, etc. Mazda has even hooked this car up to their computer system and no error code has been found. This issue has been extensiely documented with our local Mazda dealer and paperwork is available for review. This car has been a true lemon since we bought it. It only has roughly 55k miles on it.
