What are some common problems with the Mazda CX-9?

After reading tons of reviews on SUVs, I found that the Mazda CX-9 is perhaps the best value buy on the market, especially for used models. That said, I’m a bit apprehensive about any used car. Are there any common problems with the Mazda CX-9?

If you buy a used model, watch out for these common problems with the Mazda CX-9:
  • Premature engine failure, which can occur around the 100,000-mile mark
  • Failure of the water pump
  • Failure of the brake power unit, which can cause longer braking times
  • Corrosion on the valve stem and TPMS warnings
  • Clutch failure
  • Variable valve timing and stretched timing chains
  • Melting dashboards and glare
With a four-star out of five-star reliability rating from RepairPal, the
