Lexus Denso Fuel Pump Recall (NHTSA 26V222 / 26LB05) Explained
Toyota/Lexus has recalled certain 2015–2022 Lexus RC, 2016–2020 Lexus GS, and 2022 Lexus IS vehicles (Lexus 26LB05 / Toyota 26LA05, NHTSA 26V222) because the low-pressure Denso fuel pump inside the fuel tank may fail. A failed pump starves the engine of fuel and can cause a stall while driving, increasing crash risk. Dealers replace the fuel pump assembly free of charge.
Free Fix: Do NOT Pay for a Fuel Pump Yourself
If your RC, GS, or IS falls in the recall range, the dealer replaces the complete fuel pump assembly 100% free — no mileage limit, no age limit, no warranty needed. Safety recalls never expire. Interim owner notification letters were mailed June 5, 2026; a second letter will arrive once final remedy parts are ready. Call your dealer with your VIN now to get on the list.
Symptoms & Conditions
- • Engine stalls while driving or at idle — and may not restart.
- • Long crank / no-start condition, often worse when the engine is hot.
- • Hesitation, surging, or sudden loss of power under acceleration.
- • Check Engine light with low fuel pressure codes (e.g., P0087 fuel rail/system pressure too low).
- • Weak or missing fuel pump prime noise when you turn the key to ON.
- • NHTSA consequence: a stalled engine increases the risk of a crash.
The Root Cause (Master Tech Diagnosis)
The in-tank low-pressure pump is a Denso unit whose impeller can deform and swell over time. As the impeller swells it drags inside the pump housing, output drops, fuel pressure falls, and the engine starves — first as hesitation, then as a full stall. It is the same Denso pump family behind the earlier 2020 fuel pump recalls (20V012 / 20V682); this 2026 action expands coverage to additional RC, GS, and IS vehicles that were not included before.
Master Tech Insider Warnings
Crucial information every affected Lexus owner needs to know
A Stall at Highway Speed Is the Real Danger
A dying fuel pump gives little warning before it quits. If the engine dies at highway speed you lose power assist — steering gets heavy and brake boost fades after a press or two. Get to the shoulder immediately, hazards on, and do not keep cranking a pump that has failed.
Recalls Never Expire — But Don't Wait for the Letter
Unlike TSB warranty repairs, a safety recall has no mileage or time limit — your 2015 RC is covered the same as a 2022 IS. But the June 2026 interim letter means final parts may still be ramping up. Call your dealer with your VIN today and get your name on the schedule instead of waiting for the second letter.
Don't Pay an Independent Shop $800–$1,200 for This
A fuel pump replacement at an independent shop runs $800 to $1,200 parts and labor — money burned when the dealer does the updated OEM pump assembly free under the recall. If you already paid for a pump before the recall, keep the invoice: you may be eligible for reimbursement through Toyota customer service at 1-800-331-4331.

🔧 Recommended Tools: Confirm It Before the Dealer Visit
Check for low fuel pressure codes and keep your Lexus healthy while you wait for the recall appointment
Autel MaxiAP AP200 Bluetooth OBD2 Scanner (All Systems Diagnostic)
Scan your Lexus for low fuel pressure codes like P0087 from your smartphone — documented codes make the service visit faster and prove the symptom is real.
Fuel Pressure Test Gauge Kit (0-100 PSI with Adapters)
Verify actual fuel rail pressure against factory spec before condemning the pump — a weak reading confirms the diagnosis beyond any fault code.
NOCO Genius5 6V/12V 5-Amp Smart Battery Charger & Maintainer
A weak battery mimics fuel delivery symptoms with slow cranking — keep a full charge while diagnosing so you chase the real fault.
