I just noticed this message appear on my Tesla App/Tessie App. Ironically this happed on the same day my car was updated to the latest 2024.14.6. Does anyone know what this could be? The car has been driving ok so far. Error code is

PMF_a092 / PMF_a092_xtalOscillator​

Web search result: Tesla diagnostics

Alert Description
Pedal Monitor Warning: Crystal oscillator inactive.

I'd file a service ticket to have the hardware checked out.

Same thing happened to me, with this latest update.

I also noticed this code pop up in service mode. Thinking its related to the original error. All this after the latest update. Hope its nothing serious. I have a service appointment scheduled this Sunday. I will keep everyone updated.

Service guys said it was a bug that occurred due to the software update. They were unable to find anything wrong with the car.

My car is still in shop; no update so far. Will find out tomorrow. I hope it is just a bug and nothing major hardware issue.

Car is still in shop after one week. so far determine that drive train failed and will be replacing the whole unit. Cause is still unknown.

Here is an update. Service center was able to duplicate the issue. Long story short since I was under the drive-train warranty, they had replaced the front inverter for free.

Tesla rep mentioned the car was in "limp" mode; but I did not see it on the screen or felt it while driving. So best to check in your App under service once in a while.

Where in the app does it show alerts?

In Service, all I see are Schedule Service, History (of service tickets), Video Guides, and Owner's Manual.
