Happened to me on my 18 M3…..luckily I had arrived home. Steering module sensor went dead, I lift a lot weights and still could not turn the steering wheel. I always wondered what would happen on the road. Ended up they changed both the sensor and 12V battery.
Crossing my fingers that mine doesn't have this issue.
it won't, new parts already avail since Jan 19
How do you know the new parts will be replace the old ones in the build after 1/19?
It's common sense. They know they have a faulty part and have new parts designed and are fixing them on any existing cars that have the issue eg the service bulletin....so why wouldn't they cutover new mfg and not perpetuate a known problem? I put 1/19 as that's the date of the service bulletin and when they had new parts specified. So no guarantee but high probability.
That's confirmation that the system is locked down or out of power - I don't think a Tesla that's locked will let the doors open via electronic buttons if it thinks it's supposed to be locked.
There are redundant systems to maintain steering and braking during various power failure scenarios.
Any reference for details on the back up system for steer by wire?
OP's truck was dead in the garage, not on the road trip.
If it's steer by wire and the wire being an electric signal, at what point will it still steer when all power is lost? Not from a drained battery, but more from a component failure or in this case a non responsive CT?
