    I just read about this recall for overheating inverters that apparently started years ago. I have a 2012 Prius. I don't recall ever receiving anything form Toyota in the mail about this. Should I be concerned?

    Questions:
    1. Are all 2012 models affected, and if not why some and not others?
    2. Would I have received a letter from Toyota in the mail or from a dealership?
    3. How would Toyota itself know that I have a 2012 Prius?
    4. I have not had any problems with the inverter. Does that mean mine is fine?


    It was also written in the article that the software update to fix the problem has caused cars to lose fuel efficiency!

    Just don't accelerate or brake suddenly, sudden charge or discharge causes the overheat.

    You can register an account at Toyotaowners.com, enter your VIN and view any and all dealer service records your car has ever had. Any dealer can do the same if you provide them your VIN. If the E0E software flash is found among the records, you've had the recall.

    1. All 2010-2013 are affected. 2014 may not be fully affected as the recall was rolled out Feb. 2014. I'd assume 2015 is not affected but that could make an nice person of me.

    2. Not necessarily, this seems all over the place with cars changing owners and whatnot.

    3. Toyota has the VIN for your car in their system. Whether or not they associate it with you depends on whether or not you've dealt with a dealer since you've owned it.

    4. No, there is no saying when any affected inverter IPM might fail.

    Reports vary widely as to how the E0E affects both power AND mpg. My personal experience with my recently deceased 2010 was that mpg was unaffected, but it required more throttle input to get the same level of "sportiness.":rolleyes:. However, my new-to-me 2014 feels even less "sporty" than my post E0E 2010. My personal feeling on the issue is - get the E0E done so if the inverter IPM ever does fail, Toyota doesn't try to hard ball me on the ZE3 warranty extension, which repairs the failure for 15 years/unlimited miles.

    I signed up on the site and found my car, so they obviously had me in the system. Next to "safety recall" it says "no safety recalls reported". Does that mean my car has no inverter problem? Or could the recall notice have expired? Was it every single Prius made in those years, or some but not others?

    The green circle check mark with "no safety recalls reported" is an indicator your car is current on all recalls that apply to it. You can verify this completely by:

    -Scrolling down to "service history"
    -Click drop down arrow to expand the service record box
    -Click "view all service history" and "submit"
    -You now see a listing off all dealer service records for the car and can use the "view details" prompt to see each record as it would appear on an invoice.

    My 2014 did indeed have the E0E on 2/17/14. The repair order number says "software upgrade" but yours may say something different. This clearly indicates Toyota had not built the fix into at least my build date for the 2014 model year. As I said above, all 2010-2013 are affected. None of these cars technically have an inverter problem until/unless they fail suddenly. The recall is still open and considering the warranty extension and a now very public lawsuit, I doubt it will close anytime soon unless Toyota settles by replacing all IPM's from 2010 at least through the build date of my 2014.

    How long have you owned the car?

    I bought it new in 2012. I am concerned about having the work done. How long does it take and will it decrease my car's mpg?

    I know it's a few months stagnant, but my 2010 Prius just stalled while driving, going into limp mode with all warning lights on. I called Toyota & they said my VIN isn't associated with the recall and on toyotaowners com it's only showing the curtain shield recall. I think this is the ipm failure but I'm waiting on the dealership to call back with what is wrong.

    If all 2010s are affected, why isn't mine included. I bought my Prius used at a Toyota dealership in August 2013 if that matters.

    Just in case anyone comes across this googling like I did... An update:

    It WAS the inverter & my Prius was NOT a part of the recall. So even if your VIN is not pulling up under the recall, your inverter can still fail, stalling you in the middle of driving... I'm still covered under the warranty enhancement program, so the repairs are free.

    I've reached out via Twitter about why only certain VINs are included in the recall when clearly other vehicles are affected as well .

    So now I'm confused. I called a Toyota dealership about this and when they pulled up my car file there was no info about a recall. Could it be that certain 2012 cars didn't need it?

    2015’s do not have the inverter problem and are not covered by the recall?

    My 2012 got the recall. I got a letter and had to take it in. It's just a "reprogramming" which takes perhaps 30 min (when they can get to it). In my case, Toyota Canada, but the car is the same as the US ones other than bilingual stickers and km and km/hr on the odometer and speedometer. Oh, and different option packages, but they don't affect this particular recall. I noticed no difference in mileage (I keep records of every fillup). There may be a difference in throttle response but I didn't notice it. It's said by some that the IPM will still fail (maybe) even with the recall. Unlike some I can't comment on that. ;)

    But I don't understand why the dealership would not have any recalls on the file for my car if there was a recall. Should I not trust their files?

    There are no recalls on the Toyota owners website that are safety recalls or special service campaigns for my car. There is something called Takata recall. Anyone have any insight into this?

    You're not affected so that's why there's no recalls...until inverter fails. Then you'll be affected, by then it will be too late in limp mode. Just put it this way, all gen 3 inverter will eventually fail. Its just a matter of time. I know my inverter will eventually fail, rainy day fund ready for Honda Civic hybrid.
