2020/2021 Plastic Oil Pump

[Loco38SUP]

I just went thru this on my 2020. First indication is the engine oil level check. If it goes to 16% and then stops, that's an indicator that the oil pump is having issues. I did not receive any CEL warnings, but did get a low oil warning once which started me researching and trying the engine oil check, which failed at 16%. When I brought mine into the dealer I explained what the issue was, they talked to a Toyota engineer and he had them do a pressure test. It defaulted to the high pressure and thus was a failure for the test.

They then replaced the oil pump under warranty. This Toyota dealer also owns a BMW dealer so they sent it to them to replace the pump. Took just over 2 weeks total time.

If your engine oil check is failing at 16% bring it into the dealer. If not then no need to worry, but know if it does start to act up and your out of warranty, you'll spend about $2500 to fix it.

As for the other actual recalls, those aren't important at all really. The brake one.... you have to NOT press the brake pedal hard enough and then double tap the start/stop button. Who double taps the button... almost no one. The other is for 4G signals, who cares. My dealer specifically told me not to do the recalls because they have had several bricked ECU's when attempting these recalls.

To date I haven’t seen a single case of a Supra brake booster failing due to start button spamming. On the other hand yes to several bricked ECUs trying to do the brake recall.

I have, and they had been posted about here. Although, it seems I haven't heard about any other cases for at least a year or so.

Bricked ECU's from ISTEP updates are mainly from ignorant techs not putting the car on proper aux power or none at all.

People actually pressed the start/stop more than once when starting the car? How is that even possible. Every car I've had since 2014 has had the push button start and I've never pressed the button twice. I'm really curious as to how this happens.

And you're probably right about the techs not knowing how to correctly do the updates. I'm going to hold off anyway because I have an early 2020 (built 9/2019) which has the unlocked ECU, so I don't want it getting locked.

You will just need to bench unlock, no FEMTO needed. I updated my 2020 ECU last year via ISTA/ISTEP and just had to do a bench unlock.

There appears to be a growing concern for those of us with 2020/2021 owners who have the OEM plastic oil pump. While some have had this replaced by Toyota under warranty ONLY after it has failed, some are replacing them with the all-metal revised unit as a precautionary measure to avoid potential issues possibly leading to complete and expensive engine failure.

While this is not meant to be "yet another oil thread", I'm curious to see what the actual results are and how dire of a scenario is this especially when compared with the other safety issues such as the brake assist and the 4G/DCM which have actually been addressed by Toyota.

Thanks for posting this, it's been on my mind as well. I have a 6/2020 build date for my 2021 which is rather early, lucky in that there's no oil consumption, and I have an unlocked ECU, but I know it has plastic oil pump oil pump internals. I personally voted that I'm going to replace as a precaution however not right away. Simply to have one less thing to worry about.

Good to know. Thanks for the info and pics.
