High Pressure Fuel Pump

[Nicolai]

I am having, what sounds like the same problem many of you are having, on my 2020 G70 2.0L, with the Initial start in the morning taking several cranks before it will start. Once the car is warmed up, shut down, and then restarted it doesn't do it. If it sits for an hour, it will usually hesitate to start again. Took to dealership and they said there was no code and they could not replicate the problem. BS I think. Anyways, I changed the plugs and put in a new battery thinking that may have been the issue but still does it. I am leaning toward the HPFP but to be honest, I am not sold on if that it it or not. Too nice of a car to be having issues like this!

Some of the 2020 G70 2.0T had an issue with LPFP. Genesis issued a recall for those vehicles. I think it was only models produced in Q2 2020. Could be related to that.

Same exact car, same exact issue. 2019 G70 2. No mods, 40k miles.

Was told I need to replace the high pressure fuel pump after the car started stalling, sputtering and going into a “limp” mode.

Quoted around $2,000.

Just replaced the OEM Blower resister a few months ago for for a few hundred bucks, mechanic said there’s some faulty wiring with the front engine assembly harness, letting me know more issues could possibly happen if it’s not replaced (4K for the part alone).

Why would the fuel pump fail only after 40k miles? There’s been multiple instances of the same story online, so it’s not just a one off.

Hoping it doesn’t have to do with a major underlying issue like the wiring harness, else it’s not worth putting money into.

Getting a few more estimates… ugh

If you read my post #39 in the previous page of this thread, I explained one possible cause. Of course, it's difficult to tell in each individual case. On my own cars, I'd just as soon not tempt fate and gas up long before fuel tank gets close to empty.

Are you not still within the 5 yr warranty? With 40k miles and a 2019 your factory warranty should cover fuel pumps and such I would think?

The powertrain is actually covered for 10 years or 100K miles... unless it was bought used.

I don't think the Hyundai counts the fuel pumps as "power train." From what I've read, if it's not inside the engine, transmission, differential, it doesn't count.

The same HPFP is used on quite a few vehicles, G90, G80, G70, Stinger, etc.

You can buy the HPFP for about $600 from a US online OEM parts supplier, like this one: https://www.kstinger.com/high_pressure_fuel_pump-492.html

Or, you can order directly from seller in Korea, for about $300 shipped. They are all over ebay. Do a search for the part number:

35320-3L000​

Here is one example: OEM High Pressure Fuel Pump 353203L000 for Genesis G70 G80 G90 K900 Stinger | eBay

Installation instructions can be found here: https://www.kstinger.com/high_pressure_fuel_pump-492.html exactly same as G70. Not a complicated job at all. Probably 30min for an experienced shadetree.

Even if it takes a guy a whole Saturday to figure out how to do the HPFP replacement, it's worth $1700 AFAIAC.

I wouldn't doubt you're correct, so good point. Hopefully the guy will let us know.

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?

I had the same problem. I was left stranded on the middle of the road on a Sunday. Towed it to two Hyundai dealerships and they didn’t want to work on it bc they split from Genesis. I finally towed it to a Genesis dealership one hour away from home. They fixed it in less than 24 hours. Didn’t give me a loaner but lucky I had a spare car.

Mine went out last week at 100k it will give a. Code p0087 usually. Mines did. Took it dealer they replace dl high pressure fuel pump, and intake manifold

What was the cost??

 

[joegr]

What was the cost??

$0 if you have less then 60K miles. The bumper to bumper 5 year / 60K mile warranty will cover it.

 

[JCtx]

If you're the original owner, the 10-yr/100K-mile power-train warranty should cover the fuel pump too. Good luck.

Nope. It's an "external" part.

FWIW, there is an ongoing recall for the HPFP for the Kia Stinger 2.0T. Stinger 2.0 Theta II Fuel Pump Recall

I've received notices of it for my 2019. Being that the G70 2.0T more-than-likely has the exact same HPFP, a recall is probably coming for the G70 as well. If you had to pay out-of-pocket for replacement on yours, for whatever reason, you should hang on to your receipt and documentation for possible reimbursement.

An yeah, HPFP is part of the fuel system, for obvious reasons, so it is not considered part of the powertrain.

Danbury Genesis just contacted me and said it was the HPFP. Estimated total cost $1400 parts & labor.

Both. Ha ha. I've bought 8 vehicles there, and the 2 times I had to take them for a recall, they damaged it. So it's based 100% on (bad) experience. And most of the new vehicles I've bought have had oil overfilled, tires overinflated, coolant reservoir at the min mark or lower, or a combination of them, so still don't trust them. The G70 was overfilled with oil (had to suck 1/2-qt), and coolant at 'min'. I took care of that myself, as always . Already had bought an OEM pink gallon of 50/50 coolant to top off the SF, so already had it there. And sucked the extra oil with my fluid extractor.

 

[Sztiglitz]

I had the same problem at around 27k they consider it on the app as Powertrain and cost me 0$. I will upload the receipt later. following couple months down the road a new problem occured today at 36k P209600. P008800 was the pump. Car all of a sudden stutted at 40 MPH. Took them about 24 hours to fix. They paid for my Uber ride both ways; from dealership and back. I have 2019 2.0 AWD got it at 3.5k miles - stock

here is the recepit for my warranty covered the replacement.
