Hi All.

My RAff was a good doggy for a couple of month then I got this weird issue when when I am trying to take off it feels like brakes are locked and car will not go. If you kick a "gas" pedal (gently) it will start driving after 1-2 seconds and then drive OK until next long stop.

Once or twice I had weird ABS-like shake on the highway and in one occasion very short loss of power. After a second or two it normalized I was driving normally in between those accidents.

So, now car is at a dealership (atlantatoyota.com). Alex Green from Toyota was involved and they telling me now it's a traction motor issue and fix will be around $7400 (add a dead heater to that $$ as well). I was told that troubleshooting will be free and they had a guy flying?? from CA to Atlanta to look at my car and help to troubleshoot.

I do applause to Atlanta Toyota to be willing to deal with it at all :) but not sure if I am ready to pay $7400 for the repairs. I thought that my option could be to purchase extended warranty but not certain if it will be honored if I am buying it AFTER it broke.

Who have any good ideas on the subject?

It sounds like a parking pawl malfunction. This has been happening more lately. I think this is the fourth one I've heard about.

This is why people have suggested buying the Toyota Platinum Warranty. Even if you buy the warranty now, I don't think there is any way they will pay because they know the plan purchase date and diagnosis date in the Toyota systems. I believe there is also a 30 day waiting period.

Believe it or not, $7,400 is a price reduction from the ~$10k other people were told a year or so ago for a drive unit replacement out of warranty. It's still a lot of money. It might be worthwhile to call Quick Charge Power to see if they have any viable options for you.

I'd contact the guys at quickchargepower.com. I know Georgia is a long ways away, but at $7400, you could ship it there and back and maybe still be cheaper...or they may be able to source parts that a local third party EV shop could use to do the work...or they may have other ideas. Worse that happens is that they can't help you.

+1 for repair at QCP. Also, check your motor coolant level. I suspect the issue might be coolant leaking into the DU and causing the motor windings to expand. This would present as you describe and in a short time the motor will lock up completely. I believe Tony at QCP has seen this issue one or more times.
