A little late to the game, sorry if it's been discussed, did a quick search to no avail, I have a 2010 CX9 3.7(just hit 160,000miles) I have what I assume is a water pump failure, sending coolant into the oil, The funny thing is, its running temp is perfect(it is running a little rough, throwing a p0016 code), I was informed about a "water pump lawsuit" which with the mileage I have, I assume I cannot participate in, it actually started around the 150,000-mile mark, I've been driving and changing the oil frequently, so far, so ehh, any ideas on why this thing would not run hot if it's losing coolant into the engine? Unless it is not the pump(?), To me, the car is not worth the 3 to 4 grand to change the water pump, unless, of course, I am eligible for a fix from Mazda LOL!!, just trying to figure this puppy out...
