TTBOMK, a Toyota EV/Hybrid tech is supposed to be doing the swap, due to the HV involved. I don't know what their cert process involves.

---------------

I bought a set of HV gloves, but I hope to never have to use them.

Dealership still has my RAV4 EV. They now say a new drive unit should be here this weekend.

They are going to have their mechanic replace the drive unit himself. Last time I believe they flew in a Tesla tech to do the swap. Should I trust a normal Toyota mechanic to replace the drive unit? Are there issues that may arise from having a mechanic that is not fully qualified in EVs do the replacement of the Tesla drive unit?

They have had difficulties diagnosing this from the start so I am not completely confident in their skill level with this technology.

It has been 3 months since this started so I am ready to get my RAV4 back. ...
Hopefully they will tighten all the bolts / nuts in the right direction and with the right force.
But I'm not sure if they will do all the subsequent procedures. For example, will the mandatory "Coolant Air Purge"Procedure after Drive Motor Assembly Replacing be performed, which is done using the Tesla diagnostic program?.
Find out if possible what to do if not.

Replacement drive unit came in last week. The mechanic at the dealership is completing the replacement today. I am told he is Prius certified. They will keep the RAV until tomorrow for testing.

Other than the coolant flush with the Tesla diagnostics, is there anything else I should confirm was done?


Thanks!

"Prius Certified" should be enough for the HV stuff. Don't know about the coolant flush/coolant purge procedure, though, as that's unique to the Tesla.

Be sure to ask if there is oil in the transmission (not a joke, since there were precedents).
Tony Williams described in FB a situation when he got to repair a RAV4EV 10,000 mileage after replacing the engine with transmission absolutely oil-free/dry.
