Water Pump Failure Led To Engine Failure

CarComplaints.com Seal Of This Might Hurt

CarComplaints.com Notes: The only area of real concern for 2013 Mazda CX-9 owners is the brake booster.

In 2014, Mazda extended the warranty on the 2007-2013 CX-9 brake booster to 7 years / 90,000 miles. However this extended warranty has expired for most affected CX-9 owners, so buyer beware.

We had no problem with this car until this. The engine was rumored to be made by Ford. This sucks because I am a mechanic and changed many water pumps. This particular engine has the water pump in the engine. I took it to the dealership and they had to pull the engine out of the car. Removing some of the suspension and disconnecting the transmission. It took 30 days to fix this.

World Car Mazda in San Antonio, Tx sucks and so does their service. If I would have known that this repair was so expensive and difficult, I would have never bought this car. We fixed it for 1900.00. It is still a reliable car. Water pumps always go out around that mileage. It should have been easier. I'm okay with the vehicle.

My 2013 Mazda CX9 has an engine light on. I hear a cracking sound while driving on the highway. Luckily, I was able to drive home and took it to Mazda dealer. They diagnosed and told me "camshaft position sensor" which caused by the water pump went bad. Coolant water leaked into the engine and to fix it cost me about $3,500.00.

CX-9 Grand Touring FWD 3.6L V6

  • Automatic transmission

I'm so shocked I don't know what to say. How it is possible that bearings going out on the water pump? Could essentially cause a vehicle with a KBB value of $12k to be worthless.

Bought this car new, 5 years ago, 74,000 miles and the water pump breaks - leaks into coolant system and the engine is TOAST! Now what do I do? Replace the engine for $6,500 or sell it for parts and get a new car?

CX-9

  • Automatic transmission
  • 61,000 miles

I bought this car used one year after it was made. I paid $24,000.00 for it, cash. I had to put $2,000.00 in it for the three years I had it, and now the water pump went out and blew the engine. I did all the scheduled maintenance and repair. I took care of my car. I had 60,000.00 mile bumper to bumper warranty and my car blew up at 61,000.00 miles. I called Mazda and faxed over my proof of maintenance, and because I did not have it looked at with them they will not cover ANY of the cost to fix it. I am hurt and confused, it will take $10,000.00 to fix, I have kids and no job. I cannot believe they are doing me so badly.
