P0087 on Genesis: How to Diagnose & Fix
Fuel Rail/System Pressure - Too Low
4 Genesis models · 6 documented issues · 6 critical
P0087 on Genesis by model: symptoms, diagnosis and fix
The fuel control valve inside the high-pressure fuel pump (HPFP) can stick or allow excess fuel into the system, producing an air/fuel mixture that runs too rich. This causes a reduction or loss of motive power at low speeds, rough running, and check-engine warnings — increasing crash risk. Genesis recalled certain 2019-2023 G70 vehicles under NHTSA campaign 24V-528 (Genesis recall 023G); owner letters mailed September 2024. Many owners also reported the symptom (hesitation/near-stall when driving off within ~30 seconds of a cold start) before the formal recall. The remedy is an ECM software update plus inspection and replacement of the HPFP assembly as necessary, performed free of charge under the recall.
Common Symptoms
- Loss of power or hesitation accelerating from a stop or at low speed
- Engine wants to stall if you drive off within ~30 seconds of starting
- Rough running / engine surging
- Check engine light, sometimes with a fuel-rail-pressure code
- Long crank or hard start
How to Fix
First verify the VIN against Recall 24V-528 (023G) — the fix is free under recall. Dealers apply an updated ECM/engine-control software calibration and inspect the high-pressure fuel pump, replacing the pump assembly if it fails inspection. Out of warranty/recall, the OEM HPFP is replaced; the 3.3T uses Hyundai/Genesis pump 35320-3L000 and the 2.0T uses 35320-2CTB1. After replacement, clear codes and confirm fuel-rail pressure is within spec.

Fuel can leak at the pipe connection between the high-pressure fuel pipe and the fuel rail. A fuel leak in the engine bay near hot components raises the risk of an underhood fire. Genesis issued safety recall 033G (NHTSA 26V-229) in April 2026 covering roughly 26,000 GV70 from the 2022-2026 model years (part of a larger ~235,000-vehicle Kia/Genesis action). Owners may notice a fuel smell or fuel odor around the engine bay.
Common Symptoms
- Fuel smell or raw gasoline odor around the engine bay
- Visible fuel residue or wetness near the fuel rail
- Fuel smell after refueling or under load
How to Fix
Check the VIN against NHTSA recall 26V-229 (Genesis 033G). Dealers will inspect and tighten the fuel pipe connection, or replace the fuel pipe as necessary, free of charge. Owner letters began mailing June 8, 2026. If you smell raw fuel, stop driving and have it inspected immediately rather than waiting for the recall appointment.

The low-pressure fuel pump assembly can contain an impeller made from material that does not meet specification. Under high ambient temperatures the impeller deforms and interferes with the pump housing, creating mechanical resistance that shuts the pump down and starves the engine of fuel. The result is a sudden loss of motive power or an engine stall while driving, which can happen at speed and create a crash risk. Genesis addressed it under safety recalls 016G and 022G (NHTSA 23V-630 and 24V-282), covering 2022-2023 GV70 along with G80/GV80/G90.
Common Symptoms
- Sudden engine stall while driving
- Loss of motive power
- Hard starting or no-start, especially in hot weather
- Engine hesitation or stumbling
- Check engine light
How to Fix
Check the VIN against NHTSA recalls 23V-630 / 24V-282 (Genesis 016G/022G). The free remedy is replacement of the low-pressure fuel pump assembly using the recall service kit and tool per Genesis TSB 23-01-083G. Owners noticing stalling, hesitation, or hard starts in hot weather should have the recall completed before further driving.

Hyundai Motor America has recalled certain 2022-2023 Genesis GV70 crossovers because the fuel pump may fail. When it does, the vehicle can lose drive power. NHTSA's concern is straightforward: a GV70 that loses motive power in traffic — pulling into an intersection, merging, or climbing a ramp — raises the risk of a crash. This recall, filed under Hyundai's internal number 022G, is an expansion of an earlier campaign, recall 23V-630, meaning vehicles outside the original population were later found to be at risk. The campaign as a whole covers 31,440 vehicles across all of the Genesis models included in it; that figure is campaign-wide and is not a count of affected GV70s.
Common Symptoms
- Sudden loss of drive power while driving
How to Fix
The repair is free at any Genesis dealer. The dealer inspects the vehicle and replaces the fuel pump assembly at no charge to you. Owner notification letters for this campaign went out June 7, 2024, so if you bought the GV70 used or have moved, you may never have received one. Enter your VIN at nhtsa.gov/recalls to confirm whether your specific vehicle is included and whether the remedy has already been performed. Hyundai customer service can be reached at 1-855-371-9460; reference recall number 022G.

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.
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.

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 — two distinct pump part numbers in the recall (31110-D2000 Theta-family applicator and 31110-T1050 Lambda-family applicator across the campaign).
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): Genesis dealer inspects and replaces the low-pressure fuel pump assembly free of charge. Owner notification mailed June 18, 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 4 models: G70, GV70, 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.
