Oil and coolant mixed together and cause engine to die with a service code of p0016 which means per the dealer that the engine needs to be replaced. I bought this car brand new and had it service by mazda dealership consistently. This is common issue and mazda manufacturer should be cover this issue for customers.
Suv would go off in the middle of the road or highway when traveling a high speed. Took it to dealer, they say that they found oil & water mix in the engine due to water pump failure, multiple symptoms would occur as due to this condition. This issue is very series, first you get no indiction of the problem, not sure why the water pump failure causes water to enter the motor and mix with oil, it must be a mazda design problem, which they seem to know about and never issued a recall to get all the car fixed.

you are driving with your family at 50 mpe in an highway the car will just go off and you can get impacted at the rear with very horrible consequences. Will mazda issue a recall for such a series issue?
I purchased a used 2009 mazda cx-7 in june 2012. In may 2014 my check engine light came on. I took the car to the nearest auto service station which was not a mazda dealership and the engine stopped when they tried to turn it on.

lack of oil. I presented all my oil change receipts which I had changed every 3 or 4 months over the last 2 years. The auto service company also sent out their insurance inspector to inspect the car to see what caused the engine to fail and if they would be liable. Their report stated that the timing chain jumped which cause the "cam shaft retard" code. The mechanic did show this code to me on their computer before the car was towed to mazda. I reached out to mazda usa and they concluded that they agreed with american guardian and cannot help me. Now I'm left with an $8,000 bill that no one wants to cover. *Js
I was in the parking lot looking for a space when the engine suddenly shut off! Radio was still on. I had absolutely no control on the vehicle except for "gliding" to the parking spot ahead of me and braking. Once parked I turned the ignition key on off, took it out, re-inserted the key and restarted the car. The car responded normally. As a test, I backed out of the stall and parked in another one without any problem. 2 Hours later the car started without any problem. *Tr
