This doesn't match my thought:
Tx fails: 840
That means there actually were TX failures or TX aborts from a bus error state.
That should manifest in the logs as well, with possibly more detail.
I've appended some can messages from the log file on my sd card. Timestamps correspond to when I was driving. Looking at esp32can.cpp I guess errflags (aka error_flags) is a combination of several things, 16 bits of "error_irqs", 8 bits of MODULE_ESP32CAN->SR.U, and 8 bits of MODULE_ESP32CAN->ECC.U. I think 0x800000 is BIT(7) or __CAN_IRQ_BUS_ERR or "IR.7 Bus Error Interrupt". Is it saying it doesn't like my can bus? I haven't changed the way I connect to the high speed can, I tapped into the onstar connector. I guess it's possible the cable got damaged (it's under the right/passenger's seat) but it does seem to be able to receive frames without error. (And I know the engine will not run if there are problems on the high speed can bus!)
