yesterday my car wouldn’t start on the airport ramp. Check ev system take to dealer. Car wouldn’t go to ready after all sorts of trying. I got a Lyft to pep boys and got the battery Tony recommended, didn’t do the trick so it was towed to concord Toyota. They now have the tech that used to be at Walnut Creek.

Anyway, I have the Jadmeo in there and I showed the guy that took the car and told him if they are not comfortable working around, with, or removing before at a price, I would have it towed to Berkeley as it’s my understanding they are familiar.

Should I just have it towed or should I let the concord guy look at it?
I don’t want some guy with no clue red stamping my warranty. Especially with Berkley just 20 miles away.

Edit: rolled to the dealership early this am to grab some papers out of my car. Still sitting there. What do you know, it went to ready. Still telling me to go to dealership with all kinds of errors (steering, brake, and) but working. Is it possible this was a 12v problem that needs to be reset and I’ll be good to go? I guess no way to find out until the guy looks at it.

update: Said they won't touch it because of liability. Anyway, I called roadside assistance and told them that their insistence on Concord being able to work on it was wrong and I'm not driving a car that has an error message saying the brakes and airbags aren't working right. They agreed it was their error and have agreed to move the car to Berkley. Hard to believe Concord felt they have less liability giving back someone a car with brake and airbag issues vs having a certified mechanic (who is there) work on the car in their "non certified" shop...

You definitely did the right thing by having the car taken to Berkeley Toyota. Believe me, you really don't want to have your car worked on - especially for a potentially complex problem like this - by a shop that doesn't want to work on it. Toyota hates electric cars (at least ours) and many dealers treat you like a criminal for having one. It is worth seeking out better dealers, and Berkeley is the best in the East Bay (if you have a JdeMO).

Well its been at Berkeley for 5 day now. Still nothing. What makes the whole scenario worse is how they act like there is a chance I won't be covered under warranty.
"Tesla and Toyota aren't on good terms so we'll have to see if they will be able to do anything"
"you have the Jademo and aftermarket 12v battery, we have to have somebody come out and determine if one of those caused the issue"
"If Toyota decides they don't want to fix this under warranty you will be responsible for the $45 a day rental car"
Then when you ask if they decline this type of repair often they say "I don't know its case by case"

If it was just a day I can deal with it, but when this car goes into the shop its anxiety inducing. They did the same thing with the heater repair.

If this IS covered under warranty I think I'm going to start looking for someone who wants it.

I believe it is federal law that unless any modification that you had done to the car directly CAUSED the problem they have to cover it under warranty. I'm not a lawyer but thats what I have read.

This is an interesting and all too familiar story for me personally and likely one that is common among RAV4EV drivers.

Having driven this car for 4 years and owning 2, I’ve had this dreaded “check ev system go to dealer immediately” warning a dozen or more times along with a failure to power on into “ready”. The first time I took it to the dealer and nothing wrong was found, no reason for the codes. Hmm. Anyway, i’ve taken both of my cars to Berkeley Toyota about it. I no longer panic, now I turn the car on and off up to five times to get it into ready and often that doesn’t work so I have to unplug the black 12v battery terminal, perhaps a few times. This warning hit my car well before I had a JdeMO installed.

Anyhoo, these are pretty common (every few months) and often happen when I am stopping aggressively at a stop sign for example. Several times I think I touched the break and the accelerator at the same time to trigger the shutdown (oh snap, the car no likey that, my feet are too big and maybe the pedal is too close to the break). Maybe pedal and break user error is the most common trigger for the warning. Charging on a 240volt outlet has caused so occasional issues as well. I wonder if it’s a safe mode resulting from current spikes. Dunno but they always clear after restarts or a few days of driving around with the code. Mine often retains the error warning on the dash for days after I get it to go back to “ready” and drive off.

Error codes are definately a quirk with this car. It’s still a good day trip car regardless of this. If I ever can’t reset the car By cycling it on and off or unplugging the 12v, I’ll be pretty unhappy. So far, I’ve driven 70,000 miles in the RAV4EV and never been stranded, and am rarely stuck anywhere too long thanks to the JdeMO

Well it has been 25 days now. Answer is still. We haven't sourced the part yet... How long am I expected to wait. The PriusC they gave me is not suitable... My bikes don't fit in it, I'm not supposed to have a dog in it, it doesn't hold 4 people and bags. This is getting a little annoying.

I was driving, got the clunk and lost all drive and got the check EV msg. Is this just a wheel sensor issue or is this something else? Toyota won't tow it to the shop I want, the closest shop is being richard about giving rental car. I am gonna tow it in, wait until tomorrow and request a rental car so they can't charge me. Car service sucks at Toyota, you would think they would treat you a little better if they are charging $150/hr for labor.

This is my first time using the extended warranty I think.

A clunk and loss of power could be several things:

1) broken drive shaft / stripped splines
2) speed sensor out of calibration / failure
3) high voltage interlock failure somewhere
4) motor / inverter failure
5) gateway failure

It's being diagnose right now, have to wait for Tesla and Toyota to talk.

The motor was replaced from the whine, battery was replaced last year. I don't think the gateway was replaced, I am hoping it is just a speed sensor.

New Camry is not sexy or fun to drive

ive had several apparently random instances of the Check EV symptom which "went away" after serveral start/stop cycles.
So far no "car disabled" events. My son is driving the car now as his daily driver and we're up to 78K on it but only one occurrance for him.
