Upgraded stock non Bose speakers to Infinity Reference component speakers in the front with door deadening mat. Huge improvement in sound.

Here is the other obvious grounding point, where the 2 factory wires are attached.

Yes, the dealer verbally said porous casting. It cost me $3200 with dealer and Mazda discounts.

I was able to confirm with my dealer that the replacement cylinder head that was installed on my 2018 is a redesigned part to correct the "porous casting" of the original.

The chassis steel and welds are not great conductors. Thick copper wire has much lower resistance. When connected to well chosen grounding points there can be a benefit. A obvious grounding point on my 2018 can be found by removing the plastic cover on the engine revealing a factory grounding...

You really want to bolt the wire, just clipping it is not a good connection.

I also filed a complaint with the NHTSB citing a potential fire hazard due to the leaking oil. Hoping for a recall.

I got Mazda corporate to contribute $1500 and the dealer another $500 since I had used them for some service. Good luck, this should never happen!

Still waiting for the NA cracked head extension on my 2018.

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...

Maybe the battery was disconnected for some reason and the ecu and transmission were reset to the default?

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.
