I was driving on the highway and decided to switch int the left lane so I sped up and heard a big bang and what sounded like my bumper being dragged against the ground.
These issues been happening since the second month I owned my 2019 mazda 3 hatchback. 1- suspensions, they're very rough & harsh., they bounce so much for no reason, I damaged one tire already while I was driving on i476 normal highway where I stepped on…
Low engine oil message appeared on dash. Had car towed to Mazda. Had valve stem seals replaced under warranty.
My 2018 Mazda 3 has an intermittent electrical failure on the high-speed CAN network that causes multiple safety-critical systems to fail while driving.
What component or system failed or malfunctioned, and is it available for inspection upon request? The high-pressure fuel pump failed. This component failure prevents the car from starting or staying running.
Spontaneous loss of power while driving on highway. Check engine light came on. Speed limited by car. Continues to vibrate especially at idle from cold start. Code P0304 intermittently popping up.
