While driving the vehicle went to stop car and was unable to stop brake pedal was hard as a rock luckily I didn't hit anything or anyone. upon further research it seems that this model has an issues with the brake booster failing causing exactly what I experienced. As it turns out I did not qualify for the extended warranty on the brake booster due to a agreement between you and mazda my issue is it should be life of the model with no expiration date due to the fact it can happen at any moment. Luckily my family wasn't harmed and luckily someone else's family wasn't harmed because of this failure. My vehicle only has 86,000+ miles.
Brakes not working due to brake booster problem which was brought to the attention of Mazda. Mazda and the transportation authority agreed on an extended warranty which is no longer in effect. There have been many more complaints for this same problem, yet a recall has not been listed for this vechicle and alot of people are paying out of pocket. I already brought this to the attention of traffic safety and never received a return reply. Brakes are squishy than you end up having to put brakes all the way to get car to stop. People are unaware of this major brake and safety defect
Transmission & drivetrain all 22 →
I had engine failure with a complete loss of power and a shuttering of the steering wheel while pulling into a parking lot and going less than 30 miles per hour. The temperature gauze went from cold to hot suddenly. There were no leaks of coolant or oil and no signs that the engine was out of water or that the water pump had "melted". On the final car repair trip we found out that the engine has an internal water pump that failed and resulted in oil & water getting into the engine. The engine light NEVER came on, I had complained about the tire pressure light blinking on and off in November 2021 and the deceleration issue I was having. The dealer did a coolant flush 11/2021. In early March 2022 the engine shut off as I was backing out of the driveway. I took it to a repair shop nearby they could not find anything wrong except that the car went into limp mode. …
The AWD system failed leaving the car dangerous to drive in rain and snowy weather. Car is still stuck in my driveway as the front wheels are spinning and no power to the rear wheels. My Mother's AWD with similar M+S tires drove out with no problems. Waiting for the snow to melt to be able to take my car into the shop. Reading online this seems like a known Mazda issue.
