Engine overheated while driving in a straight line in traffic at low speed with temperature in the 80's. The engine block cracked as a result. The engine and the complete cooling fan assembly had to be replaced. The engine temperature had risen high on several occasions before this, while idling, driving at low speeds, and driving at moderate and highway speeds, temperatures ranging from 50's to 90's. When the overheating occurred the air conditioning also failed to function properly. I had complained to the dealership about this issue and they claimed it was a fuse. They replaced the fuse, but it did not resolve the issue.

My mazda 6 started overheating during a heavy traffic day. Ever since, I noticed it would only start over heating only when the car is idle at a light, traffic, or parked for about 5 minutes and then slowly start creeping up. If I give it some RPM, the gauge comes back to normal reading. *additional info - heater only works when riding - I have to add a bit of coolant everyday - changed thermostat, fan control module and fans work well.

The passenger side of my dashboard is melting. It is only occurring on the section closest to the window and for about 12 inches. I have tried to keep the windows open, use heat barriers/shields etc. It is even wet and gooey when the AC is on and I am driving. I have read that the plastics etc that are used in vehicles can emit cancerous odors/vapors/etc when they overheat. Can this issue please be investigated as after reading the complaints this is a robust problem that can affect the safety of many people!

I was driving with my AC on in my 2009 mazda 6 and the car began to overheat and the AC got hot. I had to pull over with my infant in the car into the nearest parking lot. The car was brought to mazda and they said that the cooling fan for the motor and the AC were faulty, but since the car was 4,000 miles over warranty, they would only give $200 toward the $907 job for their faulty part. I looked it up and there is a tsb for this part. The federal safety agency item #10032548 . If there are many others having a problem with this faulty manufactured part on relatively new cars I believe there should be a recall. It was the hottest day of the summer here when the AC went and my car started to overheat with my 6 month old in the car. My car only has 40,000 miles on it.
