Took care for routine maintenance to car dealer (Ourisman Mazda Rockville MD). No problems with car. They reported that I had an 'Coolant Leak at the Cylinder Head'. Cost to fix: $6412.47 They reported that it was 'normal wear and tear'. I found a service bulletin from Mazda whereby they admit a manufacturing defect that affected 2.5T engines. They corrected on March 25th, 2021. However, engines prior to this date had this defect. No recalls were created. No warning to owners. My car was within the mileage warranty when they identified the defect (<60k miles and < 5 yrs old). While my car is less than 5 years old, they now identified the leak, but it has over 60k miles. The local dealer said I was out of warranty and there is nothing they could do. I spoke with Mazda North American Operation and reported the Technical Service Bulletin that they put out on 10/15/21 (after they had already identified the problem, re-engineered the engine, and changed the manufacturing line), I also explained what was reported to me by Ourisman Mazda and emailed her all the documents. She reported that she would be getting back to me in 24-48 hrs.

I took my car in for scheduled maintenance and the technicians at the Mazda dealer found out the tensioner and belt needed to be replaced, when the car is less than 36k in miles. Vehicles being repaired under warranty but a tensioner should not be going out this early in the lifespan of a 2 year old car. I have found a lot of people are complaining for the same issue. This can cause the cars to not run as there-€™s no notice ahead of time that the belt and tensioner are bad. I do have paper work stating tensioner problems. Vehicles should be recalled due to poor manufacturing and parts making it unsafe on the road.

My Mazda6 spontaneously caught on fire while it was parked on a street and completely burned down. The fault/problem cause is unknown at this time but I suspect there was wiring/electrical fault and manufacturing and design defect. Both the sheriff's department and fire department were involved in assisting me in this incident. I am still waiting for reports from law enforcement/first responders. Mazda has refused to address this situation without me providing them with an "inspection report supporting the claim a defect was present and said defect caused the fire." As I was only a lessee of the vehicle, I have no possession of the vehicle and, therefore, I cannot order an inspection on the vehicle. Mazda is acting in bad-faith.

Vehixle has open recall #3719F. Took vehicle in for service on July 15 and according to NHTSA recall has even out since June 27.2019. To this day I have not gotten any letter or anything stating car has open recall when the car can turn of randomly. Will be taking car in on 08/26/19 but I'm concerned as to why this has not been addressed in any letters or emails

I made a stop at a traffic light and the green light change I pressed the gas and the Mazda6 stalled and then dragged to take off which almost caused an accident.
