P0087 on Genesis

Fuel Rail/System Pressure - Too Low

Critical4 Genesis models affectedSystem: Fuel System

P0087 on Genesis vehicles indicates fuel rail/system pressure - too low. Au7o has documented this code across 4 Genesis models — most commonly on G70, G90, GV70. 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.

Common Causes of P0087

  • •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)

P0087 on Genesis by Model

Genesis G70(1 issue)

  • High-Pressure Fuel Pump Failure Causing Power Loss (Recall 24V-528 / 023G)2019-2023

    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.

Genesis G90(1 issue)

  • Low-pressure fuel pump impeller deforms in heat, causing stalling (NHTSA Recall 24V282000)2022-2023

    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).

Genesis GV70(3 issues)

  • Fuel Pipe-to-Rail Connection Leak Fire Risk2022-2026

    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.

  • Fuel Pump Failure Can Cut Drive Power on 2022-2023 GV70 (Recall 24V282000)2022-2023

    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.

  • Low-Pressure Fuel Pump Impeller Failure Causing Stalling2022-2023

    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.

Genesis GV80(1 issue)

  • Low-Pressure Fuel Pump Impeller Deformation Causes Stalling (Recall 022G / NHTSA 24V282)2022-2023

    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.

Frequently Asked Questions

What does P0087 mean on 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 specifically, this code is documented across 4 models.

What causes P0087 on Genesis vehicles?▼

Common causes on Genesis: 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. Specific causes vary by model and year — see the per-model sections below.

How much does it cost to fix P0087 on a Genesis?▼

Repair costs vary widely depending on the root cause and specific Genesis model.

Which Genesis models have P0087 documented?▼

Au7o has documented P0087 on 4 Genesis models: G70, G90, GV70, GV80.
