2017~2025 CX-5 Dead except tail light allegedly hit by lightning

[copyoncall]

CX-5 won't start, but tail lights remain on, computer wont communicate and dealer and insurance company say lightning hit it although there is no sign at all of a lightning hit.

Going by Mazda protocol they manually replaced the parking brake and alternator modules which did nothing. At my suggestioon they checked the brake switch - nothing.

Then they tried one other module... mid cam I think, and that did not restore communication. Insurance company has paid out about $2600 and Mazda is saying it could be thousands more to figure it out so they want to total car. It has 90,000 miles, been well maintained; and I would rather have it repaired.

Anyone with any ideas? Thanks

How did dealer and insurance company both come to the conclusion that car was struck by lightning? Surely they didn't just pull that idea out of thin air.

Just a guess but maybe is the anti-theft system engaged?

You'll need to find a mechanic that can troubleshoot CAN bus issues if your Mazda service department isn't able to do this. Whatever the problem is, it's quite possible, maybe likely, that it will cost more than $2600.

Cute. Lightning conveniently falls into the "act of god" exemption in your auto policy.

Have they thought to try a new ECU?

Since when is a lightning strike not covered by a comprehensive insurance policy?? Its covered by such policies here in Aus and a quick google says the same thing for a number of US insurers such as Progressive.

I have heard of cars and boats being struck by lightning, and the fix required every harness and control unit and many sensors and ancilliaries such as radios in the vehicle/vessel/engine having to be replaced.

It may not necessarily be a direct strike on the vehicle, it can be in close proximity.

Huge job. Understandably results in insurance write-offs in most cases.

Presumably at least part of the rationale for the lightning strike diagnosis was that the car was in an area where there was a lightning storm and after said storm, would no longer start etc.

That is good to hear, if true.
