2016 Mazda CX-9

I started smelling coolant after exiting the vehicle from a drive. Coolant level was very low. Adding coolant did not last long. I could not see where the leak was. The dealership evaluated and determined I had a cracked cylinder head and the car is leaking coolant near the rear of the engine. This could cause the engine to seize should coolant get into the engine. The dealer (New Rochelle Mazda) explains the cylinder head needs replacing. The dealer also observed bad rear sway bar links. One was detached. The car is serviced at the same dealership every 5k miles. The car has approximately 85k miles. The cylinder head has been repaired by the dealer under the extended warranty. Safety risk was moderate as the car could have stalled on the highway. The component was inspected by the warranty company and dealer only. The only warning lamps that showed up once were both brake indicator lights came on and the climate control would not warm the car.
