Owner report 11729875 · 2026-04-08 (April 8, 2026)
I own a 2018 Toyota Sequoia experiencing fuel pump failure symptoms including extended crank and loss of power. This issue matches NHTSA Recall 20V012000, which affects similar vehicles with the same fuel pump defect. However, my VIN is not included in the recall despite identical symptoms and safety risk. I am requesting investigation into whether additional VINs, including mine, should be included in this recall due to ongoing failures.
