Hello everyone,
Need some help here. My mom drives a 2023 Genesis GV-70 with 15,000 miles and a 2.5 turbo car. She tells me that the car will not go past 40 mph. You accelerate on the gas and once it gets to 40 mph the car won't go any faster. Not sure where to start with diagnosing.
Hi everyone.
So i towed the car to the Genesis dealership today, and here is the Issue as per the tech listed on the service bill: “upon inspection verified that when driving around would feel as if vehicle would want to stall or have limited engine power. Inspected and completed replacement of low pressure fuel pump assembly, after repair cleaned DTC’s present. Test drove vehicle and vehicle now has full range of power and operating to manufactures specs.”
What does all of this mean? I’ve never heard of a car having multiple fuel pumps.
What does all of this mean?
It means the low pressure fuel pump failed prematurely. Kwality Hyundai parts.
I’ve never heard of a car having multiple fuel pumps.
Of course they do. These days it's very common. Any car with GDI has a low pressure and a high pressure pump. Even some older cars did, I know from experience that the early 1980s Saab 900 had a small feed pump and a main pump in the fuel system.
In any event, thanks for letting us know how it turned out. Hopefully this is not the start of a general trend of early failures for that car.
@chucktobias I agree with you. Let’s hope Genesis quality exceeds Hyundai quality.
It’s the same company, do you think they’re going to do any better? They’re just gonna throw in extra leather and massaging seats and stuff to get you to buy it
Not sure where to start with diagnosing.
Scanning for codes and live data would be a good start. Maybe record data while the problem happens.
@chucktobias There's no codes already checked with my OBDII scan tool my scan tool isn't able to read live data from the car unfortunately.
You pretty much need that to be able to do any kind of diagnosis on a late-model car. It doesn't take a very expensive scanner these days. (Mine cost about $50 and can read, graph, and record data. Of course at that price level it doesn't do bidirectional testing or read manufacturer-specific codes.)
Other than that you can check the usual suspects like air and fuel filters, fuel pressure, spark plugs, catalytic converter clogging. None of those should really be a problem on a newish car with such little mileage, but you never know.
Those cars are pretty complex. Depending on how deep the problem goes it might require a dealer-level scan tool for diagnosis.
@chucktobias That's true, but I am extremely surprised that her Genesis is having major mechanical issues at 15,000 miles. That seems odd.
It's not all that odd for a Hyundai product but I thought maybe the Genesis was built better than their run of the mill stuff. Maybe not.
