Damn, the crack could happen again. I only drive about 5000 miles a year now in retirement with 63k on the odometer. I will be selling my car at around 90k to avoid a crack, although this will be years down the road.
Somewhere upthread I though I saw a comment that the cylinder head being used for replacement on my 2018 head that cracked in February have not been revised with a better improved casting. I seem to remember from either Mazda USA or the dealer service writer stated that the head had been updated...
My 2018 had a cracked cylinder head. It is total BS they only extend the head warranty on the CX9 and not my CX5. They did provide some financial help but it still cost me $3200. Hoping for a recall...
Final resolution. Mazda paid $1600 toward the head, only 95% of the cost, maybe a non admission of total liability? The dealer also offered a $500 discount thankfully.
Still $3000+ out of pocket. I have been assured the new head is latest spec and does not have the thin casting of the original.
2018 with 59,000 miles.

Case filed with NHTSB and waiting for a class action.
I have noticed an oil burning smell in the engine bay. I noticed slight seepage around the timing chain cover and cleaned it off. Checked the back of the cylinder head and it is dry, does not appear to be cracked. I did not find any significant leaks. I removed the oil filler cap on the hot...
On my 2018 I removed the plastic restrictive grill by the hood latch for more air flow. Also use AEM DryFlow filter. I am considering trimming the snorkel tube where it enters the airbox as it appears to be longer than necessary and adding a small bit of restriction. Has anybody done this yet?
I have been using ground cables for years, starting with my 2004 Toyota Matrix XRS.
Currently using 10ga Monster Cable to the engine grounding point near the throttle body and 8ga to the grounding point near the passenger fender, both originating at the battery negative terminal. Throttle...
I plan on doing an ATF drain and refill at my dealer soon at 50k miles.
Wondering if there have been any transmission issues among those with high mileage and no fluid change?
