I just had my on board charger replaced. Car worked perfect for 22 months and 29,000 miles than one night my phone started getting charger started and charger stopped notices every 10 minutes. I didn't hear it right away, but after about 40 minutes I went out to garage to see what was going on. About every 10 minutes the car would try to start charging, I could hear clicking in the EVSE like the breaker was going on and off and than the car would stop trying to charge. It would repeat that every 10 minutes. I tried my 120 charge cable, same thing. Dropped car off at dealer, they had to contact corporate cause they had not seen that trouble code, but corporate knew what it was right away and sent out a on board charger right away. Car still stayed at dealer for a week.


Damchi, my car broke down again this time with the same exact symptoms you are describing only they say that they already replaced the charging unit but the car still won't charge. The car has been sitting in the dealership since Nov 7th.
They have summoned Tesla engineers who arrived "reluctantly" and gave no further recommendations. BTW, my dealership is only 14 miles away from Tesla factory!
Would you be able to share with me the details of your work order? Maybe that will help the dealership repair the car.

#2496 just got a new charger, and I have yet to pick it up.

After successfully charging #1134 overnight, I drove about 9 miles, then plugged in.

"Check EV System"

I did the four ON / OFF cycles to clear the error message, however, as soon as I plugged back in, the error returned.

I disconnected the 12 volt battery, then reconnected, and still get the error message.

The lights blink above the charge port like it is charging, but the main battery contactor never closes and the onboard charger does not close the contactor in the EVSE.

Each attempt results in "Check EV System".

So, I'll just swap one car for the other to get a new charger.

20,000 miles on #2496 and 50,000 miles on #1134.

Tony:

Are you just unlucky or is it because you drive that much more than the rest of us. I am at 17,500 mi on #1086 and have had essentially no problems that required dealer intervention.

Is there a difference between the 10 kW charger on the RAV4 and the Model S (and the MB B type)? If not, how can it take 43 days to get a replacement charger. If there is a difference, why is there one?

Will MB put up with such poor service with Tesla, or do they have them by the short hairs with regard to up time and time to repair on the B type?

Is Toyota required by law to maintain a parts inventory for recent model year cars, or can they legally say that a car under warranty can't be repaired for months because they didn't bother to make/acquire sufficient replacement parts.

Has anyone considered a Class Action lawsuit against Toyota to require them to obtain the parts in advance and keep them in stock rather than going hat in hand to Tesla each time they need a part?

Has anyone approached Tesla to see if we could buy an extended warranty from them for the Tesla parts in the car?

I love my RAV4 but if Tesla offered me a sweet trade for a Model S 70D I would part with it in a heartbeat.

With three RAV4 EVs, we have almost a total of 80,000 miles.

So, that's a completely different situation than somebody with... well, a lot less.

With #1134, it's the last major Tesla part that has NOT been replaced, except the battery.

The other two cars have actually been quite good:

#3021 - 11,000 miles - oil leak repaired out-of-state under warranty

#2496 - 20,000 miles - charger (two dealer visits) and motor (speed sensor)

That's it for those two cars.

#1134 - 50,000 miles - everything except the battery, including two motors


I doubt that there are ANY differences between a Model S charger and a RAV4 or B-Class ED. Just some programming.

I doubt that there are laws requiring levels of parts.

We do not have any sales agreement with Tesla. There will not be a warranty from Tesla to consumers.

There is an entirely different relationship between Daimler and Tesla than there is with Toyota and Tesla.

Class action lawsuits are possible... there is a law firm somewhere who will take your money. Your chance of success: 0%

Team Rav4EV-

I'll add my name to the Onboard Charger replacement group. Happened 3 weeks ago. Got in the car and noticed it was not charged overnight. Went through the manual and found the System Malfunction Error with "Contact Dealer" as the only solution. Tried using different EVSE, including Leviton 40A, 110Volt included with car, and JESLA. No charging occurred.

Its been 2 and a half weeks with no expected date of completion. And I have been pushing them hard. They apparently diagnosed the software and determined that the Onboard Charger failed. Tesla provided Charger and replaced it this week, BUT now it is shorting their EVSE. They need another charger and/or will consult with Tesla.

My mileage is 23,464 and this is the second major hardware problem I have had. The first was gateway ECU.

I did have the Check EV System Error come on once about 10,000 miles ago, but it went away and never showed up again.

Will keep you updated.

Meanwhile, I'm driving a Ford Fusion Titanium rental and am loving it. The MPG is about 25-30, but the car build, interior, and performance is wonderful. Drives like a BMW.

Charger is definitely in the "Top Ten" list for the Rav4 EV. I always love the posts that say, "I've had no problems with the car except for (one of the items listed)".

In other words, it had a problem.

viewtopic.php?p=20079#p20079

Issues with RAV4 EV:

1) Speed sensor - RECALL ITEM - vehicle will pop into neutral and stop, power steering disabled)

2) Gateway / communications "ECU" (can disable vehicle, usually a Check EV light)

3) Motor / gear box noise (requires motor replacement)

4) Heater failure (which then takes out the DC to DC)

5) DC to DC failure

6) Onboard charger failure (can't recharge vehicle... except JdeMO equipped cars with CHAdeMO quick chargers)

7) Leaking oil from gear box (I've had this on both one RAV4 and our Mercedes B-Class ED that shares the same Tesla Model S drivetrain)

8) "CHECK EV SYSTEM" message du jour (requires four ON/OFF cycles)

9) Charge Timer

10) Entunes

11) 12 volt battery

Well, Tony, as you can see with a list of 12 MAJOR problems, I feel as f my car is doing just fine having just 15% of the issues listed!

My lease is coming up in a year and I really wanted to buy it and keep it, BUT I'm just scared of these problems and not having parts or anyone motivated to help me fix them when I own the car.

I love having an all electric SUV, so maybe the Model X will finally be available in a year!

UPDATE: I took the car in on May 18th and received an estimate of July 1st for when the car may be ready. "Our hands are tied, since we are waiting on Tesla for the charger." I am waiting on a second replacement charger as the first one short circuited the EVSE.

UPDATE! My car has been at Simi Valley TOYOTA since May 18th. No news as to when it may be ready. I'd be more upset but Toyota is paying for a large comfy SUV rental I'm using to shuttle my kids around to Lego Land and the Grand Canyon while we wait for the Rav4 to be fixed. That being said I'm paying the gas prices and miss my electric car.

At 2 months, on July 18th, I'm thinking of reporting this to someone, but whom? BBB? State off California?

Apparently Tesla doesn't care to fix this and Toyota has no fix for it either....
