There was a coolant leak on my Mazda CX9 Signature with a 2.5T engine, and when driving the engine temperature started increasing slightly before taking off and turning red. I had to pull off to the side of a busy interstate road very quickly and shut the vehicle down before it overheated any more. Once I got the vehicle to the dealership, they told me it was a cracked cylinder head leaking coolant, and that it was an extremely common problem for the 2.5T mazda engines around about 60k miles, and they were actively working on one in the shop where I was for the same problem. Mazda is not currently helping with engine swap or any repairs as a result and is sticking the customer with the bill.

I bought a used 2017 Mazda Cx-9 from West shore Honda in tampa in July of 2020. They screwed me financially and I'll handle that separately. There has been an ongoing issue since the first few days after buying the car. I've complained multiple times via email and phone. I've been trying the service department countless times. They keep stating it's a tire issue. To the point they have replaced the tires 3 times. After the second time I had already decided it's not tires. The car has a very rough ride when I'm motion. Once you got 80 it wobbles. After several weeks the wobble can be felt at lower speeds of 55/60. The check engine light comes on but I'm told there's no codes when they diagnostic the reading. I've expressed that when I pull into my garage within 30 seconds to a minute there's a loud pop it's when the car is not in motion when it's been parked and turned off is when I noticed it. I brought it to my personal mechanic just to look at and drive and he's pretty certain it's a powertrain bearing or something of those sorts. Brought it back to westshore and they put another set of tires on it. This is been going on now for 9 months and after doing research online and some of the NHTSA ids this is a problem and I do not feel safe. And it needs to be handled the amount of complaints in times that I visited that dealership to fix this problem and all they do is put new tires on it is asinine. I have tons of documentation the same documentation that's at the dealership I do everything via email for that reason.
