High Pressure Fuel Pump

[joegr]

I had the same problem at around 27k they consider it on the app as Powertrain and cost me 0$....

That's a powertrain diagnostic code, but not something covered by the powertrain warranty. It was covered by your bumper-to-bumper warranty.
(I'm not arguing that the powertrain warranty shouldn't cover it, just saying that it actually doesn't.)

The car can have powertrain DTC codes that are caused by something other than what powertrain warranty covers.

For example, if your radiator leaks and your engine overheats and seizes from low coolant, there will be a whole bunch of powertrain DTC codes. 10/100 powertrain warranty won't cover the leaky radiator (part of cooling system), or the damages it caused.

That said, because this is already a recall item for the sister car Kia Stinger, the same is likely coming for the G70. If and when that happens, it will be covered regardless.

My 2019 G70 2.0T needs a new High Pressure Fuel Pump at only 36,000 miles. I find it to be unusual so early. All of the regularly scheduled maintenance has been done by the dealership. No mods, as car is completely stock. Has anyone else experienced this problem?

This just happened to me as well. Mines a 2019 G70 2.0T Sport all stock as well, no mods and only has 54K miles. The cars been going limp for about a month but I couldn’t duplicate it and no errors showing but yesterday that same code P008800 finally popped up so I have an appointment tomorrow. Sounds like a nightmare. Everything work fine after you got this replaced?

mine works like a charm no issue since replacement

Any idea how easy (or hard) it'd be as a DIY job? It sits on top of the engine, and it's driven by a cam, right?

Replacing the pump itself is pretty straight forward. However, replacing the high pressure fuel line to the rail may require the intake to come off. The manual asks not to re-use the older pipe due to risk of fuel leak.

My G70 is with the dealer right now for a new HPFP. I'm at about 91,000 km (56,500 miles). Weirdly, I did not get an engine code, rather when I was checking my oil level - it was overfull and smelled like gas. The dealer says it's leaking into the engine, but assures it has not done any damage to the engine. In accordance with my luck, the part is on backorder with apparently zero units available for order in the world, with none sitting on a boat or in a plane. It now has to be ordered for manufacture in Korea, so she's out of commission for about a month while I roll around in my loaner.

Does anybody know if it's still an issue on '23s? Knowing Hyundai (and Kia and Genesis, of course), they typically don't do crap for years and years, so I wouldn't be surprised if it is. But just want to know, if an HPFP is in my future, assuming I keep the car that long (7,800 miles now). Thank you.

Thank you very much for that. It wouldn't make any sense having to remove the intake, but I'll check those 2 lines on my G one of these days. Weird the manual says to replace both lines; seems like a money grab. And also says to replace the bolts, so maybe they're TTY ones. Finally, it also calls for a special tool to reinstall the high-pressure line. Do you also need that tool (whatever it is)? Man, all of that is probably quite expensive. I'd also have to search how to depressurize the lines, since that article doesn't say. Thanks again. Hope my stupid car doesn't act up during my ownership.

I just had to replace my high pressure fuel pump on my 2019 G70 and it only had 69,000 on it those things should not go out that soon with under 100,000

ME TOO! With engine stuttering and check engine light on, i took my 2020 G70 to the dealer. P01720 - system too rich. Mechanic could smell fuel with the engine oil and suspects fuel leaking into the valvetrain area. They are going to replace the HPFP; but it won't be any time soon. I was brought over to a rental car agency and put in a Nissan Rouge. (Not happy about this but was told that Genesis will not provide their own vehicles for long term loans.)
Anyway, I am wondering:

1. How prevalent is this faulty HPFP issue with Genesis? Should there be a recall?
2. How likely are other components to be damaged or life shortened as a result of the faulty HPFP (spark plugs, gaskets, fuel lines, etc.)?

I think you are worried about the wrong parts. All of that should be fine. I would worry about the oil contaminated with gasoline causing extra wear to internal engine parts (bearings, cams, and so on). If there's not much gas in the oil, and you didn't run it in that condition for long, then there should be no problem. The repair should include an oil change.

Yes, they have said they would include an oil change; but if fuel is leaking into the valvetrain area and contaminating intake and crankcase areas, you would think the gaskets/seals would be comprimised.

So how does raw fuel maybe enter the valve train area? We have direct injection engines so are injectors also bad somehow and flooding the engine/piston with too much fuel? Seems fuel pump is not the only culprit here? Genesis can’t get hold of the new pump easily? That same pump should be used between Stingers too so HMC ought to have them available unless the whole product line is bad?

The high pressure pump is driven by a lobe on the camshaft. It is very possible for a defect in that pump to spray gasoline inside the valve cover. There's no air-gap involved, the lower part of the pump is in the oil. We are told the fuel pump is failed. There's no reason to imagine a failure with the injectors too at this point.

In the old days, the low pressure fuel pump for the carburetor was mounted to the side of the engine and driven by a lobe of the crankshaft. It was not unheard of for the fuel pump diaphragm to rupture and pour gasoline into the crankcase.

Thanks for the clarification. I do remember the old fashion fuel pumps. Seems those liked to mark their spot with a dribble from the weep hole indicating a leaking diaphragm. I had borrowed a buddies 1972 Winnabago back in college days to go skiing and it developed a fuel pump leak in route. Only way we knew something was wrong was gas gage started dropping pretty fast for we we leaking fuel quickly. We were towing a VW beetle as our drive car to get up the mountain so we unhooked it and drove to the nearest parts house for a replacement fuel pump for a dodge motor. Did the repair on the side of the freeway. So much room around that motor I could almost stand in the engine bay. Things were much simpler and easy to R&R back in those days.

My neighbor just told me that he got a message regarding recall on fuel pump regarding the disintegration of the impeller in the fuel pump on his GV70

That is the low pressure pump (in the gas tank), not the high pressure one (on the engine).

I just had this same issue P0088 on my 2019 G70 55,000 miles. They aren't even letting me get into the dealers shop for 4 weeks. Is this something I can drive on? I pushed asking and they wouldn't budge on getting in earlier.
