2003 Acura MDX Engine cooling Problems

“Noxious sulfur odor inside and outside the vehicle which is likely related to the catalytic converter. I was first advised that Acura knew of this problem which was related to a new pellet inside of the converter. Acura now says that there is no problem. I am being advised that this terrible odor is normal on this vehicle.”

“I just bought an used 2003 Acura MDX on jan 30th with 87,000 mile on it. Just after 11 days on feb 11, 2010, I noticed that some brown colored fluid is leaking from the front passenger side. It's not just dipping, there were lot of fluids coming out. I opened the hood and notice that the fluid was overflowing from the radiator reservoir. Next morning when I start the car and tried to run it just stopped in the middle of the road and engine light came on. I had to tow the car to a dealership. …”

“I was driving my 2003 Acura MDX at 30-35mph all of a sudden there was a flicking noise like a belt hitting against the car.

Because this is a family car this incident is dangerous if traveling at highway speed. I feel the need to report it. Thank you”

It was such a high cost due to they had to remove the transmission and the engine to get to it. …”
