CX-9 3.7L V6

  • Automatic transmission
  • 84,000 miles

This is my son's car that he bought used last year. He spent months looking for the right car. He loved the way it drove and handled. Without any warning, the car started shaking, and he pulled to the side of the road. He had it towed to where he had just had the oil changed, and was told the gasket blew. They still owe money on the car. He was going to get a new engine, but after reading about other people's issues, he cancelled the engine. He was told by some former Mazda people that they know there is a problem. I just found out my brother has a 2013 Mazda that had the same thing happen, but the Mazda dealership replaced the engine for him free of charge.

CX-9 Grand Touring

  • Automatic transmission
  • 58,000 miles

Our only car, a 2013 Mazda CRX-9 with only 58,000 miles on it that we had regularly serviced blew a head gasket and made a 'milkshake'... the coolant mixed with the engine oil and created a thick slurry that cycled through the engine which caused it to die on the highway on an island with our little 3 year old twins. This is engine failure that will cost 10k to repair. A little googling tells me this is not an isolated occurrence with this make and model. Class action law suite anyone? Who's with me?!

My husband rode with the AA tow truck driver while I carried 2 gigantic car seats with my two 3 year olds to the ferry and ferry back to the City and walk to a taxi to get home. Nothing short of a nightmare. And this happened the weekend before they started preschool... When we really need a car.

Mazda dealership wasn't able to locate any new engines but found a used engine with 126k miles on it would cost us $10,600 to replace or we could sign up for a repair part that is on back order but there's no saying this will fix the issue - that's $8,600... Or "we can walk over to the sales floor and see what Mazda can get you into". OMG. No thank you.

CX-9 Leather V6

  • Automatic transmission
  • 69,500 miles

A week after we got our car back from the dealer for a warranty repair (see next complaint), there was a puddle under the car, which looked like coolant. Our local mechanic could not find a leak. After some extensive searching, he found that coolant and water had mixed with the oil and that the engine needed to be replaced.

I had the car towed to the mazda dealer. They came up with the same diagnosis. The problem was caused by a failed headgasket and timing cover. Cost for new engine: $10000!!! On a car with less than 70000 miles that was purchased brand new!!!

After two weeks of calling Mazda customer service, the dealer said mazda denied covering the repair because of the expired warranty and because the oil changes were not performed by the dealership.

I have been trying to dispute this with Mazda, but have not been able to get one return phone call. I am beyond frustrated with the apparent low quality of the parts used in my car and the lack of concern and customer service from mazda.
