Hey guys just bought a new veloster N pp last weekend. Right after I drive it off the lot it feels slow, and I notice the “turbo” gauge never rises off 0 even at 4K rpm+. Literally always 0.0 and Feels really slow. Was wondering if anyone else had this issue, Hyundai is looking at it day after Christmas. Feeling pretty bummed.

By 4K+ I mean 4500 tops. Still in the break in period

 

[nomad17]

No, that's very odd. I'm surprised it wasn't noticed before they sold you the car. No limp mode lights on the dash or anything?

So, I once had this happen after installing my BOV and throttle body spacer. I had forgotten to tighten down the hose clamp from the charge pipe to the intake manifold and 1 good pull blew the loosely connected charge pipe off. No turbo. I panic. Car is slow.

Pop the hood and see what I've done, fix it, purrs like a walrus again.

It's not the RPM that matters. I don't know if you've had a turbo car before but if you baby it to get up to 4k RPM you won't get any boost. You have to be aggressive with the gas.

Yeah, in the test drive it felt a ton quicker, I for sure would have noticed if it was that slow. no warning lights or anything.

yeah romping on it doesnt help it, still reading 0.0

ill check it more thoroughly tonight, but it would have to have been loose from the factory. doesnt inspire much confidence hoping she isnt a lemon.

Making me miss my rotary already :crying::crying:

 

[guybo]

That sucks dude. Keep us abreast!

BOV or BOV solenoid possibly. Actually, the best thing to do is take it back as quickly to the dealer as possible. One of the vacuum lines on the solenoid might have come off or the BOV discharge pipe came loose.

I noticed the same on my car, Open the N screen and I never see any boost. I don't hear the turbo either.

 

[RedVN]

Take it to the dealer.

 

[WoodmanMN]

It's a brand new car under warranty, take it in!

 

[RedVN]

Don't keep driving the car either. The issue could be a simply as one of the boost solenoid lines has cracked at one of the fitting, the boost solenoid has failed, the recirculation hose has popped off the BOV fitting or the OEM ECU software need to be reflashed.

Someone else had the same issue recently and I believe their particular fix was; their Hyundai Service Department re-flashed the OEM ECU software. No matter it's Hyundai's issue and you need to take it in hook up the GDS and diagnosis the issue.

You're not alone.

Exact same issue. Had the problem a couple of days ago (2020 N PP @ 10k Kms.) Also no CEL. . I brought to Service and they said that they ordered a Boost Pressure sensor. supposed to come in this week.

I'm pretty sure they did not reset the ECU or anything.

 

[RedVN]

Go to SXTH Element and purchase a MAC BOV Solenoid. Replace it after they install the new boost sensor. Weh you get to this point, PM me and I'll tell you how to install it. It's a simply task.

 

[whitecomet]

So they replaced the Boost Pressure sensor and when I drove the it's still the same issue, I went back to service and they said I need to leave the car for a day or two.

Will keep you guys posted.

I'm assuming if I disconnect my battery: will it reset my ECU ?

 

[nomad17]

I don't understand how a car is returned to the customer with the same exact issue it went in with.

Same here, I just thought they knew what they're doing and did not test drive the car.

So I left the car there today and hopefully they find out whats going on.

They simply need to reflash the OEM ECU Software with the GDS.
