P008A on Genesis: How to Diagnose & Fix
Low Pressure Fuel System Pressure - Too Low
1 Genesis model · 1 documented issue · 1 critical
P008A on Genesis by model: symptoms, diagnosis and fix
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.

Frequently asked questions
What does P008A mean on a Genesis?
P008A stands for "Low Pressure Fuel System Pressure - Too Low." Generic OBD-II code, most often seen on direct-injection and diesel vehicles that use both a low-pressure lift pump and a high-pressure pump. The PCM compares the commanded low-side fuel pressure to what the low-pressure fuel sensor reports and sets this code when actual pressure (or fuel volume/flow) falls below the expected value. Because the high-pressure pump is starved, the engine can run lean, misfire, hesitate under load, crank a long time, stall, or go into reduced-power mode. This one should not be ignored - sustained low supply pressure can damage the high-pressure pump. Note that some manufacturers define this code slightly differently. On Genesis it is documented across 1 model: GV70.
What are the most common causes of P008A?
The most common causes of P008A are: Weak or failing in-tank fuel pump / lift pump, Clogged fuel filter or restricted fuel line, Faulty low-pressure fuel or fuel rail pressure sensor giving a false low reading, Leaking fuel line, injector, or pressure regulator on the low-pressure side, Low fuel level or contaminated/wrong fuel, Fuel pump control module or wiring/relay fault. The specific cause varies by vehicle.
How much does it cost to fix P008A 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.
