You're still under full factory warranty. Take it in to the dealer and have them verify the noise. Ask for a new drive unit (motor). It will probably only get worse. Even here in Seattle, it only took about a week to get the new motor to the dealership and a few days before I could go in and have the work done. Mine also made some "CLUNKING" noises especially when in stop-and-go freeway congestion and when first putting it in Drive or Reverse.

We have a 2014 Rav 4 EV with 25K miles. It seems to have developed a whine that I don't think was there when it was new. Does anyone know if this is a concern? Our lease is up in February and we love the car so much we are thinking of purchasing it but not if there are going to be future problems. Appreciate any advice. Thanks.
If you are considering purchasing it, buy the Toyota Platinum Extended Warranty before the vehicle reaches 3 years or 36k miles. There is a thread here talking all about it.

Yep, whine/whirring noise during acceleration usually means drive unit replacement. Extended warranty is a must if you're keeping it a few more years.

So, I took it to the dealer and after keeping it a couple of days they determined that the noise was not normal. They then kept the car and spent nearly two weeks trying to get a response from Toyota in terms of what to do. Finally, they called me with the 'good news' that they would replace the 'drive line' but it would take 4-5 weeks to get one. I picked up the car today. My lease is up on Feb. 15 and I don't think they will have it in by then so I believe will just turn it in and lease a Bolt. Too bad they are not very good at supporting these vehicles and what kind of a deal is this where the drive system goes out after 25,000 miles?

I wouldn't say "the drive system goes out" after 25k miles. It's just one component inside the drive unit assembly that starts making a whine noise during acceleration. And it doesn't happen to every car. The clunk noise I think is the bigger, albeit less frequent, issue that also requires replacement of the drive unit. Hopefully the issue has been corrected in the newer drive units.

It seems that if the drive unit is whining, it usually goes out. Mine went the clunk route, but the good news is that after mine was replaced, it is now whisper quiet.

I read some comments that the drive units rebuilt since last summer are improved and should hold up longer.

Maybe we can get more feedback here from some that have been recently replaced. I am waiting another 10,000 to take mine in.

When was it replaced? How many miles so far?

There a thread devoted to the clunk noises:
