I purchased a 2018 mazada cx5 in april. in may i noticed that the brakes were hesitant to stop and that they also make grinding noise. i immediately contacted the service department at mazada. the service advisor told me that because the car was new it would make grinding noise and that they would eventually ease up. it is now november and the issue still exist. in june my passengers seat belt began having difficulty latching causing the censor to go off. this happens daily. in october my tire pressure light came on stating that the tire pressure was low. i placed air in my tires and the censor light never went off. on october 18, 2018, i went to the mazada dealership for a scheduled maintenance, informed the service advisor of my concerns and they stated everything was fine and the censor was reset. today is november 2, 2018 and my tire censor is back on. my brakes are still grinding and now they slide before stopping and my passenger seat belt still is not latching. this is a safety hazard to myself and passengers.
