Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Lexus IS · 2018–2020
The low-pressure fuel pump impeller can deform due to excessive fuel absorption, causing the fuel pump to become inoperative. This results in engine stalling while driving or inability to start, creating a serious safety hazard. Toyota/Lexus issued a massive recall (20V-863) affecting over 1.8 million vehicles across multiple models.
Common Symptoms
- Engine stalls while driving without warning
- Difficulty starting or no-start condition
- Engine runs rough or sputters at speed
- Fuel pressure warning codes
How to Fix
Replace the fuel pump assembly at any Lexus dealer free of charge under recall 20V-863. The dealer replaces the entire fuel pump with an updated unit that uses a redesigned impeller. If you have not received a recall notice, contact your dealer with your VIN to verify eligibility.
Owner tips & cautions
- WarningThis is a safety recall — do not delay getting the fuel pump replaced. Engine stalling at highway speed has caused multiple accidents. Check NHTSA.gov with your VIN for recall status.

Honda Accord · 2018–2021
The 10th generation Accord (2018-2021) is affected by the largest Honda fuel pump recall in history, covering over 5.7 million vehicles. Denso fuel pump impellers were manufactured with improperly molded low-density material. The impellers deform over time under fuel exposure, expanding and interfering with the pump housing, causing the pump to slow or stop entirely. Symptoms appear gradually as difficulty starting, rough idle, and stalling, progressing to complete no-start. Engine stall at highway speeds presents a serious crash risk. Honda expanded the recall multiple times (20V-374, 20V-714, 23V-111) as the scope widened.
Common Symptoms
- Engine warning light illuminated
- Difficulty starting - extended cranking before start
- Rough idle on first start of the day
- Engine stuttering or hesitation during acceleration
- Engine stalls while driving at any speed
- Engine cranks for 3-5 seconds before starting
- P0087 code (Fuel Rail/System Pressure Too Low)
How to Fix
Check recall status immediately at owners.honda.com or call Honda at 1-888-234-2138. NHTSA recall 20V-374 (expanded by 20V-714 and 23V-111) provides FREE fuel pump module replacement at any Honda dealer. Parts availability was delayed through 2021-2023; call dealer to confirm parts in stock before scheduling. Until recall repair: keep fuel tank above 1/4 full, avoid repeated hard starts. If engine stalls on road: pull over safely and call Honda roadside assistance (covered during active recall).

Honda CR-V · 2018–2022
The 5th generation CR-V (2018-2022) is included in Honda's largest fuel pump recall affecting over 5.7 million vehicles. Denso-manufactured fuel pump impellers were made with improperly molded low-density material that swells and deforms under fuel exposure, interfering with the pump housing and causing the pump to slow or fail. Engine stalling at highway speeds has caused collisions. This is the same recall affecting the 2018-2022 Accord, Passport, Pilot, and other Honda models. Honda expanded the recall multiple times as the scope widened to cover additional production dates.
Common Symptoms
- Difficulty starting - engine cranks longer than normal before starting
- Rough idle on first start of day
- Engine hesitation or stumbling under acceleration
- Engine stalling while driving at any speed
- Check engine light with P0087 (fuel pressure too low)
- Engine cranks but does not start (complete pump failure)
How to Fix
Check recall status IMMEDIATELY at owners.honda.com with VIN or call Honda at 1-888-234-2138. Recall 20V-374 (original), 20V-714 (first expansion), 23V-111 (final expansion) provides FREE fuel pump module replacement at any Honda dealer. Parts availability was severely limited 2021-2024 - call dealer to confirm parts in stock. Until repair: keep fuel tank above 1/4 full and avoid repeated hard starts.

Frequently asked questions
What does P0230 mean?
P0230 stands for "Fuel Pump Primary Circuit Malfunction." P0230 means the engine computer detected a fault in the fuel pump primary circuit — the control side that switches the fuel pump (or its relay) on and off. The PCM energizes this circuit to run the electric fuel pump that delivers fuel to the engine; if it sees voltage that is too high, too low, or out of expected range, it sets this code. Because the pump may not run correctly, the engine can crank without starting, stall, lose power, or hesitate. This is a circuit/control fault rather than a direct measurement of fuel pressure.
What are the most common causes of P0230?
The most common causes of P0230 are: Faulty fuel pump relay, Damaged wiring or connectors in the fuel pump control circuit, Corroded or loose ground/power connection, Failed fuel pump or fuel pump driver module, Blown fuse or fusible link, Open or short in the primary control wiring, Faulty PCM driver output (rare). The specific cause varies by vehicle.
How much does it cost to fix P0230?
Repair costs for P0230 range from $30 to $2,000, depending on the vehicle and root cause.
