Get a call today:
The dealer replaced the DC-DC converter and the resistive heater.
When they powered the high voltage back on the computer would not respond to diagnostic signals on the OBD2 plug.

Toyota now thinks my modification of the volt/amp meter I attached to the J1772 INLET is causing problems on the CANBUS of the car.
Going over to the dealership today to disable my volt/amp meter.


Yes, a purely analog thing that isn't even connected to the CAN bus is causing the problem. Geniuses.


Get's even better.
This dealer is about 45 miles away, due to accident on the 101 I took a backroute (10 miles shorter) but it turned out maintenance made the 118 into a one way street.
So took me 1 hr 15 minutes to get to the dealership.
I had all the necessary tools with me, but asked a person from the office to come with me.
Car would not give the "click" of main contactor with brake pressed and the on/off switch activated.
I disconnected the 12 volt battery, opened and disconnected the Main breaker/high voltage disconnect (which they disconnected to work on the HV dc-dc converter & heating element).
I re-seated the HV breaker/disconnect.
reconnected the 12 volt battery.
Car came to live (loaded navigation etc)
pressed brake and "CLICK" HV came online. problem fixed

My 2.5 hours back and forth for a 2 minute procedure that the certified technician should have done in the first place.
But suggesting that an anolog device is the culprit
The EV technician was off today, so tomorrow he hopefully will finish reassembling the rav4ev and I can exchange it again

If that was me, the service manager would have received a long lecture about competence and blaming the customer for absurdly unrelated things.

So did you go ahead and disconnect the meter? If so, I can practically guaranty they will blame it anyway.

Nope, I told them that the problem was fixed, while someone of the company watched how I solved it.
That that would mean it wasn't my modification , that it wouldn't be necessary to disable the meter.
They at least agreed on that.

Classic newbie mistake. Thankfully, easy to fix.

I've talked dealers through this before, when they couldn't get the car running after working on the High Voltage system.

Did you advise the dealer of the Toyota Service Bulletin TSB-0111-14?


I got the final words from Toyota Customer Experience case manager Thorn and it's not covered by this service bulletin. Toyota offered 30% of the cost and I will be responsible for the rest $4300. The replacement part and labor is warranted for 12 months so any RAV4 EV owner can pay up to $6200 every 12 months for this problem.

Well you can say buy extended warranty. Yes it's my stupid idea to trust a Toyota to keep running and the heater problem is just matter of comfort and convenience. It's not. This issue can totally render the car to be useless and a piece of junk with Check EV system screen of death. At max you can buy 100K miles extended warranty but after that none can afford this cost every year.

I've read top 10 problems before purchasing it. The top 1 is heater, and I thought I could live without heater or I could just pay $2500. However it's not true. $2000 is just for heater core itself and then often the DC to DC converter need to be replaced, another $2400, and then labor to make it > $6200 job.

Please pretty please warn people it's not $2500 or without heater that one has to deal but it's really bad investment. Of course, my next car won't ever be a Toyota or Lexus. They put their name on this RAV4 EV but shamelessly blamed it on the join venture.


Now I wish some gurus can tell me how to disable this darn heater so it won't ever be broken again so I don't have to deal with this anymore in the future.

I know this message can harm me in a way that RAV4 EV will be sold at lower price, but it's the truth while I am being honest to any future owner.

How many heaters have been replaced twice?

Seems like an assembly defect to me as replacements seem to hold up fine.

Sheldon Brown (Rav4 EV manager) told me on the phone that there was a defect in the Denso heaters.

It's extremely unlikely that a failed heater would be replaced more than once.

It's odd that he acknowledged the defect but Toyota did not issue a recall on my car. Therefore they "thought" they fixed it with late 2013 version, but mine failed after 3 years and 36K miles. Has anyone got the replacement and it's still good after 3 years or 36K miles yet? Probably not.

My 2012 had the cabin heater replaced early in its life (probably 2013). it still works good at 81,000 miles.
