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.

I was driving on a street and my check engine light, tcs/dsc light, sbs/scbs light, mrcc light, and warning light appeared on my dashboard. My car then started putting or jerky. It felt as my car was very weak as if it was going to give out. This is the third time these same malfunctions appeared. Each time it occurred I took my car to the Mazda dealership. The first time they did not find a problem because the warning light had already turned off. The second time(September 5), they gave me a new battery and new computer software. It is now at the dealership again. This situation is very scary and I need to know why this is happening

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.
