I have a 2017 Mazda CX‑9 Grand Touring AWD with about 64k miles. My CSP11 coverage runs until around October of this year, and I haven’t seen any symptoms of coolant loss or head issues so far. As low as the miles are, I'm worried that the worst is yet to come -- or maybe I'm past the danger zone?
CarMax just offered me the same amount I originally paid, so I could walk away with no loss (I've only had it for 5 months and just learned of the issue).
Given the known 2.5T coolant‑intrusion/cylinder‑head failures, I’m trying to understand how common the issue actually is. For those who’ve owned or worked on these engines, would you hold onto it or take the money now before CSP11 expires?
Looking for real‑world experiences to help me make the call.
