A few days ago I received an email from Karma offering the Powertrain Protection Package. This sentence stood out to me:

"The program is designed to offer you a comprehensive rework on the traction side of the vehicle and a two year limited service warranty."

Wondering what the "comprehensive rework" includes?

 

[FiskerPhilly]

Removal of the RDM and performing updates to prevent c clip failure and loosening of the pinion. As well as inspecting Traction motor splines. As far as I know if the splines are worn, that is customer responsibility.

Any repairs that the car needs is the customers responsibility. In order to qualify for the warranty anything that isn't working correctly has to be replaced case in point if you AC is blowing out all the vents die to a ripped blend door blind the HVAC unit needs to be replaced .

@FiskerPhilly - are you saying as part of the inspection the authorized service center will remove the RDM, replace the C clip (if needed), and tighten the pinion nut? If so, this type of work sounds like the RDM re-work that was also completed under the CSP.

It is indeed the reworks that we've been speaking of. Basically every car that hasn't had a new RDM in the last 6 months needs it done as a preventative. The way I read the program docs, it appears to be included in the $4500. However if your splines are worn beyond spec while it's apart, the motor replacement or rebuild exchange is on the customer. Still seems like a good deal. I'm not the final say on this, we are actually having a Web meeting next week to clarify all of this so for now don't quote me exactly on this. Btw, we CSPS aren't making a penny on this warranty, so for that reason only I'm not a fan. However, if I'm an owner (which I am) depending on my situation (as in original RDM/motors) this scenario would be a no brainer. ****, having the RDM reworks done alone is worth more than half the warranty cost. So you're in theory paying a little over $2k for the warranty itself. I'm not going to speak of TM rebuild or exchange costs as I don't think that pricing has been set yet. I will have firm answers on alot of this by end of next week. I will be up in Connecticut delivering the Stormtrooper Karma to its eager new owner

Hi FiskerPhilly, It is my understanding that if your RDM's SN does not end in "003" then you are out of luck getting the powertrain protection, even if your splines show no wear. Is this correct?

What am missing?

My Karma with 12,500 mi runs perfect, I have never upgraded the software post
collapse, and am obviously naive about RDM ETC.
Will someone please help me understand the issues.
Thanks

I've heard similar rumors. Harleyguy, FiskerPhilly can you guys give us any info? I had the RDM/traction motors done as part of the settlement, but having VIN# 49 has me a bit worried if these rumors are true.

I don't really undestand the RDM issue either, in fact; I'm confused as to the differences between the RDM and traction motors. My car has about the same mileage as yours. I thought everything was up to date after the last warranty service. I'm glad I opted in on the extended warranty as they are including the RDM work as part of the deal.

Traction Motors are the electric motors ...
RDM is the module which 'connects' the two motors to the axis to redirect the power from the motors to the wheels.

@BillyO: This may help explain:

Not my best editing work, but it should be helpful in visualizing where the components are.

 

[BillyO]

OK, got it! The differential...sort of

Yes, that's part of it. But unlike a traditional differential, this one has two power inputs (one per motor) which makes this is a lot more complex than a traditional differential and unique to this car.

My understanding is that we have 2 Traction motors whose rotors have splines (which are like teeth on the rotor shaft & which can wear badly in some cars) that attach it to the single RDM which is the Rear Differential Module. Is that right?
