In fact I think the "motor" problem in Norway had to do with grease levels in the transaxle, which had nothing to do with the motor itself.

Completely wrong. From Tesla's Annual Report:
The Tesla Factory in Fremont, CA and Manufacturing in Lathrop, CA
We manufacture Model S and certain components that are critical to our intellectual property and quality standards for Model S at the Tesla Factory. The Tesla Factory contains several manufacturing operations, including stamping, machining, casting, plastics, body assembly, paint operations, final vehicle assembly and end-of-line testing. In addition, we manufacture lithium-ion battery packs, electric motors, gearboxes and components both for our vehicles and for our original equipment manufacturer customers at the Tesla Factory. Several major component systems of our vehicles are purchased from suppliers; however we have a high level of vertical integration in our manufacturing processes at the Tesla Factory. We recently commenced production and machining of various aluminum components at our facility in Lathrop, California.

This language has been present since 2012. Here is where the language was added in the 2012 report:
Powertrain Component Manufacturing
In addition to developing our Model S and future vehicle manufacturing capabilities at the Tesla Factory, we are currently designing, developing and manufacturing lithium-ion battery packs, electric motors, gearboxes and components both for our vehicles and for our original equipment manufacturer customers. These activities occur at our electric powertrain manufacturing facility in Palo Alto, California and at the Tesla Factory.

They moved off of Fukuta a _long_ time ago. No doubt, Fukuta still supplies some components to Tesla, but that's it. Tesla makes their own motors now, and has since 2012.

Why do you keep posting such obviously erroneous information?
You posted this in another thread awhile ago. It is completely and utterly incorrect. Tesla makes their own motors for the S and the X. I've seen them being produced in the Fremont factory.
Why do you keep posting such obviously erroneous information?
Transaxle = does not require recall of a motor. Take a look at the trans axle in most front wheel drive cars - the transaxle is independent of the motor and transmission.

The grease story doesn't add up - and trans axle is not part of motor=transmission assembly.

The motor, reduction gear/differential (I assume this is what you are referring to as the trans axle), and inverter/rectifier are all in one assembly in the Model S -- this is called the Drive Unit. It is not like a normal gas car. So if there is any problem with any one of those items, the whole assembly is removed and replaced. It gets customers on the road quicker to just replace the whole assembly, rather than disassembling it and repairing the component that failed. That is why the whole DU (motor, gearbox, inverter) was replaced when the gearbox had insufficient lubrication in the Norway incident.

You continue to prove you have no idea what you're talking about. There is no transmission in the Model S, it's a transaxle/differential which is installed as a unit with the motor and inverter.
Here is the port information for the bill of lading - contents include motor, stator, etc...

Yes. I realize the single speed transmission is integrated with the motor.

We know Tesla buys motor parts from Fukuta. From your link:
They even repeat it 3 times so you can't miss it, yet you managed to.

If GM designs a motor, and has others supply some of the motor parts, and GM builds it, it's a GM motor.
Fukuta is a supplier of steel lamination stacks for the rotor and the stator.
The stator winding is done at Tesla in Fremont, as is the rotor assembly (insertion of conducting copper, shaft, machining, etc).
The lamination stack is just one part of the assemblies.
As Tesla ramps up production for Model 3, the lamination stack fabrication process will inevitably be in-sourced.
I would know, I worked there for 4 years and helped design the rotor production lines.
Panasonic is a publicly traded and fiscally sound supplier + excellent choice
Fukuta - is a tiny private company. IF Tesla Motors wants to grow the major constraint is the ability of Fukuta to handle QA for higher quantities and expand manufacturing line to support Tesla growth. GM selected LG for their Bolt motors.
Why would Elon Musk trust a ting obscure supplier for the most important component of the Tesla Model S and X?

Actually it clearly says AC Induction Servo Motor, and those motors in the pictures are not Tesla motors.

I was referring to GM's ICE motors.
