Plugin Charger issues

I am not sure if anybody else has this problem, but the dealership hasnt seen anything like this.
With my 2012 plugin, I set the timer to charge the car between 2-6 am. But, I plug it in at 6 pm when I get back. However, the car starts charging at 6 pm, instead of 2 am.
I have reviewed the manual to verify step by step how to charge, and did the same at the dealership. Its been at the dealership for 3 weeks now and they have no clue what to do.
Has anybody else run into problems like this?
Thanks.

 

They haven't got a clue. They involved 'corporate' Toyota. Replaced the battery charging unit in the car, tried a different cord, messed around with some stuff in the dashboard (sorry no details on that), and nothing is changing it so far.

 

At the dealership, there is no problem when they try using the 220 v charger, but at my house I have the 110. When they tried the 110 at the dealership, they were able to recreate the problem. I then had them try a different charging cable, in case the cable was defective - and same issue. We went at this step by step, and are able to see a blinking green timer when we turn off the car. Shortly after we plug in the car, the timer goes away and the car starts charging - regardless of the time.

 

Not sure about the ecu. The car charges just fine - just when I plug it in. I only know this because I generally would just plug and walk away in the past. Recently, I used the car within a hour of plugging it in and had a full battery - although the charger said to start at 2 am. I am sorry I dont know what the ecu is.

 

I would assume thats where they should've started before replacing the battery charging unit (which they said is quite pricey) - but I will wait and see. I was just curious to see if anybody else on the prius boards have ever had a problem like this. Google didn't lead to much for me, so figured I'd actually post something.
Thank God the car is still under warranty.

 

BTW, I am curious - what do owners do when Toyota says they dont know what to do about your car? I bought a CPO, and am currently driving a rental, but I am not sure what happens if they just throw their hands up in the air.

 

The rental and all expenses so far are covered by the dealership (Stevens Creek). I am just hoping they figure something out.

 

CharlesH, you can set the timer for when you want the charge to be complete or when to start. I tried both and having this problem. My understanding is that the 110 takes longer to charge, thus the 2-6 am range, sorry for confusing the issue.
