Owner complaint summary

While driving, I received a warning that the engine in my car was overheating. Upon arriving home and parking, I noticed pooling under the car. My car was due for an oil change so the next day I dropped off the car for the oil change and mentioned the overheating message and leak to the technician thinking the fix would be routine. To my surprise, I was told my vehicle had a serious coolant leak related to a cracked cylinder. I was advised to take the vehicle to a Mazda dealer. Morrie's Mazda in Minnetonka, MN confirmed the cracked cylinder head which required a full engine replacement despite the car being only ~5 years old and having ~63,000 miles. Mazda had issued a technical service bulletin on this issue but had not issued a recall. As a result, I was left with a large repair bill to replace the engine in a relatively new car. This is a serious issue and I feel Mazda put my life and others in jeopardy by not recalling vehicles and letting customers drive with the risk of the engine overheating.
