What Owners Say

Other engine starting/ignition problem

"Internal coolant leak caused hard starting and rough idle."

Anonymous, MI (2007 Mazda 3 Touring 2.3-L 4 Cyl)

"every time the vehicle was refueled, the pump that re pressurizes the gas tank would not work and the vehicle would not start. in order to restart the vehicle after refueling or opening the gas cap and releasing the pressure, the throttle would have to be engaged to some degree which occasionally led to starting the car with a flooded engine. this pressurization problem began to occur at all times, leading to the car idling very rough and occasionally turning off completely while idling due to the low fuel pressure. replacing the part responsible for pressurizing the fuel tank seemed to resolve the issue for a short time but the underlying rough idling and occasional failing to start still occurs."

Other noises & leaks problem

"Two mechanics have been unable to isolate this rattling problem. It doesnt affect the cars performance but is very disturbing. Despite owning the car for nearly 18 years with excellent reliability and performance if this problem cannot be fixed I will get rid of the car."

What Owners Say

Head gasket

"The head gasket has a small internal leak. Cylinders 2 and 3 had small amounts of coolant in them causing hard starting and rough idle. I was able to correct it using AC Delco cooling system stop leak tablets."

Engine Cooling

What Owners Say

Thermostat

"Thermostat replaced October 2020 after check engine came on. This time (February 2024) no check engine light but cabin vent heat would fade when vehicle not moving for example at a stop light. This condition went on for a month, then engine temperature gauge started climbing as well as cabin vent heat completely stopped. Thermostat replaced again and overheating and lack of heat from vent resolved."

Other/unsure

"Rear shock (?) was broken when we hit a pothole on an interstate highway 30 miles from our house. When we got off the road, we passed a still-open auto repair shop and they told us it was safe to drive home. We did so after the event we were going to, and took the car to our regular repair shop the next day."
