P0087 on Genesis by model: symptoms, diagnosis and fix
A manufacturing defect on certain 2021 G70 cars with the 2.0L GDI four-cylinder, built March 31–July 20, 2020, left a plastic burr on the low-pressure fuel pump's jet nozzle. The burr can block the nozzle and obstruct fuel flow to the engine, which can make the engine stall and increase crash risk, especially at higher speeds. NHTSA lists 319 affected 2021 G70s, a small and tightly bounded build population, so this is a VIN-check issue rather than a fleet-wide pattern.
Common Symptoms
- Engine stalls while driving
How to Fix
Ask a Genesis retailer to check whether recall 005G / NHTSA 20V569 remains open for the VIN. For affected vehicles, the recall remedy is to inspect and, if necessary, replace the low-pressure fuel-pump jet-nozzle housing at no charge. Stalling or fuel-pressure symptoms require professional diagnosis; a completed recall does not by itself rule out a later low-pressure fuel-system fault.

The low-pressure fuel pump impeller can deform under high ambient temperatures, causing it to interfere with the pump housing and shut down. Symptoms include rough idle, hesitation/stumbling, MIL illumination, and engine stall while driving. Genesis recalled ~31,440 GV70/GV80/G80/G90 vehicles; GV80 production dates Nov 4 2021 through Sep 13 2022. This expanded the earlier recall 23V-630 (Genesis 016G), which covered 2021-2022 GV80 built Jun 9 2021 through Dec 3 2021.
Common Symptoms
- Engine stalls while driving
- Hesitation or stumbling under load
- Rough idle
- Check Engine Light
- No-start after heat soak
How to Fix
Free recall remedy: Genesis dealer will replace the low-pressure fuel pump assembly. Owners should call Genesis at 855-371-9460 or check VIN at NHTSA.gov to confirm coverage under campaign 24V282 / Recall 022G.
Sources for this issue (2)
Per NHTSA Recall 24V282000 / Genesis 022G, low-pressure fuel pump assemblies in ~1,364 G90 sedans (2022-2023 MY, built Jun 2, 2021 - Sep 14, 2022) may contain impellers that deform under high ambient/underhood temperatures, causing mechanical interference with the pump housing and shutdown. Affects both 1st-gen (3.3T Lambda / 5.0L V8) 2022 G90s and 2nd-gen (3.5T Smartstream) 2023 G90s. The recall lists two G90 pump part numbers: 31110-D2000 and 31110-T1050.
Common Symptoms
- check engine light
- engine hesitation
- rough running
- sudden stall while driving
- no-start after heat soak
How to Fix
Recall 022G (NHTSA 24V282000, an expansion of 23V-630): Genesis dealer inspects and replaces the low-pressure fuel pump assembly free of charge. Owner notification letters were mailed June 7, 2024. Check VIN at nhtsa.gov/recalls or call Genesis at 1-855-371-9460. Do not delay — a sudden fuel pump shutdown in traffic increases crash risk.

Frequently asked questions
What does P0087 mean on a Genesis?
P0087 stands for "Fuel Rail/System Pressure - Too Low." This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode. On Genesis it is documented across 3 models: G70, GV80, G90.
What are the most common causes of P0087?
The most common causes of P0087 are: Clogged or dirty fuel filter, Weak or failing fuel pump (lift pump or high-pressure pump), Faulty fuel pressure regulator or control valve, Restricted or leaking fuel lines, Faulty fuel pressure sensor, Air in the fuel system or running low on fuel, Worn high-pressure pump (direct injection/diesel). The specific cause varies by vehicle.
How much does it cost to fix P0087 on a Genesis?
Repair costs vary widely with the root cause and Genesis model; each issue on this page carries its own estimate where one is published.
