NHTSA Complaint #11492830 — 2017 MAZDA CX-9

The first sign of an issue was an oil pressure indicator on the dashboard, but upon inspection, the oil levels seemed completely normal. The dashboard light went away shortly after that. A day later, I was on my lunch break and parked my car in a garage for 45 minutes. On the drive there, I did not notice any issues and was able to operate the vehicle fine for the short distance that I drove. When I returned to my parked car, there was a large puddle of oil underneath. I immediately had a mechanic take a look at the car. The mechanic was able to identify a cracked cylinder head, which led to water and coolant entering the engine. He highly suspects that this caused a blown head gasket in the car as well. As well as that, the car's starter, which worked just fine on day 1 of the issue and has never had any problems before, has totally ceased function. If I had not noticed the oil pool underneath the car and driven back to work as usual, it could have caused the engine to seize and create a very dangerous situation for myself and others on the road, including but not limited to the potential of an engine fire with the level of oil lost. The car was up to date on its servicing, including oil changes. Two ASE certified mechanics have inspected the vehicle and confirmed the leaked fluids and aforementioned issues. No other professionals inspected the vehicle (insurance representatives, law enforcement, etc.).
