Our Cybertruck Had The Rear Motor Inverter Issue - Here's What Happened (I was surprised by the FIX)

[Derektsla]

wasn’t everyone supposed to get new motors with early vins?
Im 4k vin haven’t heard snything or had problems with 10k miles

same here. 4K VIN, 10k miles. No issues. Maybe we got a lucky batch.

Did anyone have vibrations with regen braking prior to the rear motor being disabled.?

August, 15k miles inverter rear and module go out, recall came out didn't have to change as it was replaced with new part said tech at service center while i was getting sail and wiper motor replaced with recalls on those. Now, "High Voltage error, HV Batt issue, Coolant blocked to rear motor, rear steering disabled"...just keeps going on and on. When will it end?

My rear motor/inverter just failed. 16k miles dual motor vin late 3000s.

Limited to 65mph. But says okay to drive with just the front motor
600 miles from home, debating to try to drive it home. Not that I really have another choice. I’ve got family and pets with me so I can’t really just fly home and leave it here at a service center.

No but at 60 it does give shutters a bit

Adding mine to the list of rear motor failures - took delivery Dec 30; today I pulled out of a parking lot and the dreaded turtle icon appeared and the truck went into limp mode. Taking it in tomorrow. Does the rear motor failure make the front motor any more likely to fall? Am I likely to get stranded en route to the SC? It does say it's OK to drive.

Let's keep each other updated as to how the fix is handled

Update: I'm advised the issue with my rear motor is likely due to extreme cold shrinking the volume of oil in the motor such that the pressure falls below a threshold and the rear motor is disabled to protect it. The solution is to top up with a bit of extra oil to add pressure in these conditions. For context, it was -29 C yesterday when the alert happened. I'll have that service done in a week and a half.

After an initially rocky start, the SC folks did a fantastic job on all the issues I had today. I'll have to cancel a road trip I had scheduled this weekend, but otherwise, all seems well. I'll report back after the service appointment, or if additional issues manifest.

I wonder if there’s a way to identify problematic cars. My VIN is 35k range which is well below your 47k range. It’s possible all trucks are impacted ?!?

Looks like mine might be a unique issue caused by extreme temperatures, rather than a failure if the motor or inverter - see my post above.
