CX-9 Touring

  • Automatic transmission
  • 85,000 miles

The PTU (Power Transfer Unit or Transfer Case) in our CX9 started leaking black tar, just one or two drips a day near the rear of the engine. No other symptoms occurred. I took it to Mazda and they said the PTU needed to be replaced. They explained that Mazda Corporate had a warranty on the thing but that it expired about a year before. The dealership said they could still send a request for assistance from Mazda Corp and see what they said. They came back with an "offer" to cover the cost of the part and stuck us with the cost of the labor.

We ended up having to pay $600. The part fails because of a design flaw! This should have been a recall, but instead Mazda does a crap partial warranty that most CX9s won't qualify for and then sticks us with the cost to repair it. I will never buy another Mazda and will tell everyone I care about to avoid them like the plague. They seem nice new, but they won't last.

Side note: the "Brake Booster" is the exact same story on this vehicle.

CX-9 LX V6

  • Automatic transmission
  • 50,000 miles

Car is very well taken care of. Religiously get oil changed & tires rotated each visit. It only has 50,000 miles on it, seems early for such a huge problem. If it wasn't covered under warranty it would have cost $2,536.52 to fix. Poor quality/design.
