Toyota Continues Massive Recall, Prius Stays Exempt

Amongst one of the largest recalls Toyota has done, the Prius remains aloof from the crowd. Here is what I think.

Toyota has now inflated the number of fuel pump recalls on their cars to around 2,000,000. While this is a staggering number, a vehicle that remains exempt from all this noise is—the Prius.

What makes Prius and the other hybrids so unique that they are not included in this recall. Here is what I think and what you should consider when looking for your next Toyota.

Why The Prius And Other Hybrids Are Not In The Recall
The list of vehicles that are on this fuel pump recall is pretty extensive. The recall covers Toyota and Lexus models, and this is the list.

  • 2015 Lexus NX 200t and RC 350
  • 2017 Lexus IS 200t and RC 200t
  • 2017-2019 Sienna and Lexus RX 350
  • 2018 Lexus GS 300
  • 2018-2019 Lexus ES 350, GS350, IS 300, IS 350, LC 500, LC 500h, LS 500, LS 500h, RC 300, RC 350, RX 350L
  • 2013-2015 Lexus LS 460
  • 2013-2014 Lexus GS 350
  • 2018-2019 Toyota Avalon, Camry, Corolla, Highlander, Sequoia, Tacoma, and Tundra
  • 2014 Toyota FJ Cruiser and Lexus IS-F
  • 2014-2015 4Runner, Land Cruiser, and Lexus GX 460, IS 350, and LX 570

If you look, you will see only a couple of hybrids on this list. The question here is, why?

I believe that the hybrid powertrain is the reason. When a Prius or other Toyota hybrid shut off, they can still drive. I think this is one of the reasons that Prius and different hybrids are not under scrutiny.

Another reason I believe that all these cars, which are now using direct injection systems, have a common fault. The low-pressure fuel pump or the pump in the tank is used across all the models shown above.

Now, I need to research this and dig up if that is 100% accurate, but I think it is, and here is why. Toyota, GM Ford, Mazda, and every other manufacturer look for ways to save money. If Toyota can have Denso build a fuel pump that will work in most of its models, it will save them loads of cash.

Using the same part in multiple applications cuts costs by knowing exactly how much money it takes to manufacture that part. If you know certain production variables, your result is better profit margins and hopefully better cars.

In the Toyota case, I believe they used the same part. I did a random sampling of the list and chose three random vehicles to compare, Avalon, Camry, and Sienna. Each of those vehicles has the same high-pressure mechanical fuel pump part number. To me, it would make sense that Toyota would do the same with the low-pressure pump.

Why The Fuel Pumps Are Failing
My belief in why the pumps are failing is not because Denso is a crappy company. Recalls happen for various reasons. Usually, it is due to a manufacturing error.

One of the machines that did not wind the copper wiring inside the pump properly could have been at fault. It could be that as the pumps were pressed together and the housings were damaged. Who knows. The point is these things happen, and Toyota is not the only one it happens to.

Conclusion
I am not defending Toyota or Denso for what is going on. The company is fully aware that this mistake is on them, hence the recall.

I believe that Prius is exempt from this recall because it uses a different fuel pump and has a different drive system than most of the other vehicles on the list.

If you plan to buy a new Toyota, a Prius or hybrid option looks like a tried and true method you should consider.

I am not saying Prius could not have an issue, but my professional observation of why I believe it is not on the list.

Until next time, stay safe out there and drive on happily. By the way, have you Winterized Your Prius Yet? be sure to check out the article.

Much Toyota manufacturing is in the US, including OEM parts. The Prius has only been made in Japan.
2019 Highlander hybrid. Hybrid system failure. Dealer had to drop tank to replace fuel pickup tube, which had a vacuum leak. They replaced low pressure in tank fuel pump at the same time as preventative measure. I believe that it is the same pump.
I hadn't checked, but I know most of the recalled vehicles have 6-cylinder engines. You don't see the Prius, Corolla, Yaris or other exclusively 4 cylinder models on the list other than the two Lexus 200 series. It is likely they have direct injection and the same high pressure pump.
Toyota still the best and most reliable brand.I still have a 2007 camry never had a problem

What if not the manufacturing is the culprit but the. Toyota's designing level ?
