2015 V8 Dying at 4500 rpm

[mth]

Ok so its be a while since my original post on my car shutting down at 4500 rpm's at hard acceleration or gradual roll to 4500. The fuel lines they ordered finally came in and were installed today. I am pleased to say that was the fix. Tech stated he could barely get any air to blow through old lines.The parts replaced were 31301-B1150 and 31310-B1000.
So for all V8 owners whose wives drive the car most of the time you may want to occasionally check hard acceleration past 4500-5000 every now and then. The car ran perfectly in normal driving with no codes reporting and my wife had no clue anything was wrong. I discovered this while trying to pass on a two lane road.

I have an almost identical issue, 2015 Genesis 5.0 with Tech package not ultimate. Went to get on to freeway and it cut out with a loud thud and felt like was hitting brakes. Could floor accelerator and rpm pegged at between 4k-4.5k rpm and car would not go faster.
Was able to reproduce all the way home. Moved into manual mode and noticed car was in third gear. Manually shifted to 4th and higher and it shifted but still limited at 4500 RPM. But with the higher gears the car would go faster.
Car would accelerate and move as long as it didn't hit the high (4500 rpm) limit.
Called Dealer said they had never heard of such a thing. Took it in because I consider this a safety issue. After car sat for two hours before I was able to take to dealer car returned to way before. I had been driving it for a couple of hours on the freeway before this happened so it was hot.
Been at dealer now for 3 days with the expectation it will be there another 2-3 days per Hyundai tech line they called. The rear light TSB recall has been done prior to this. They are checking for "failure of fuel line pressure on 100% acceleration" or at least that is what I was told.
Have you had any updates to your situation?

Could be the oiled filter fouling the MAF. Just sayin'

I put a new K&N filter on an Olds Aurora a number of years ago and it gummed up the throttle body. I have used paper filters ever since.

This issue has nothing to do with what air filter you have. I have had this issue twice now. Both times it was the upper fuel line. The first time it happened I had K&N air filters in for about a week. I put new stock air filters back in the car to see if that was the issue. Still dying. I then took it in and they replaced a upper fuel line. I have had the stock air filters since first repair and the same issue returned after about 8k miles. The fix was the same this time as last. The tech who works on my car did say the part did appear different than what was on the car. Maybe that means it is an upgraded part to fix the issue. We will see....

@mth - Is you Genesis still working at high revs?

I've had the same problem - the dealer already replaced the fuel lines but the problem persists. They are working with Hyundai but seem to have no idea. After 11 days this is getting old very quickly.

What did the dealership say? Its sounds like a injector problem or something like that, How many miles do you have on it. and If its a 2015 it should be covered under the new car warranty.

 

[UglyTuna]

@Bill57 - The 2015 I bought was a leftover and currently has about 1,700 miles. It is fully covered by warranty and the dealer tells me that they are working with Hyundai. As of today they have had the car for 12 days - It is getting very frustrating.

 

[Bill#57]

I can't imaginat what your going though. I think is about time to get lawyers involved. they need to either get it fixed or get you a new car. let me know what happens.

Does the dealer or Hyundai pay for a loaner?

If so, what kind of car did they provide?

The two times my Chrysler 300C needed to be kept by the dealer they put me in an Enterprise car - usually FCA products, typically absolutely terrible Dodge vehicles, base model shit-boxes that I wouldn't drive long-term even if they were free.

Yes - they have provided a loner - a lesser model. We're on day 14 with no resolution in sight .... this is getting very old.

My 2015 started doing this recently (7500 miles) - cutting off well before redline under full acceleration. Please update if you get this resolved and post what the issue was. I plan on taking mine in to have it fixed on my next oil change since it's driving fine otherwise.

Top of previous page stated that the new lines fixed the issue...

New lines did not fix the issue in my case. It is possible that the new lines were also bad - The dealer told me they were not. It's been 21 days and they don't seem to have a clue.

Day 24 starts with this Saturday ending a very frustrating week.

Despite stopping by the dealership, leaving a message for my service rep (he was on vacation) and calling and leaving a voice mail the following day, I have no communication from the dealership as to what, if anything, is happening with my car.

Thursday I escalated to the Service Manager and have not received a call back for 2 days.
Friday I escalated to the General Manager and did not receive a call back.

The only bright side is that I received confirmation from the USPS that Hyundai has received my lemon law notification so that process has started.

I also sent Hyundai Customer Care and email detailing my story and ending with:

"Rarely have I seen a business that communicates so poorly with its customers and never have I seen two senior people, the Service Manager and the General Manager, not respond at all to a customer.

I’m at a point where I do not know where to turn. I am truly disappointed and thoroughly disgusted with my Hyundai and my Genesis experience. I will contact the BBB, State Attorney General and every other person, organization and online message sites I need to in order to bring this matter to resolution. Additionally, I will be turning the matter over to my attorney next week to ensure that all legal matters are properly handled."


Does anyone have any additional escalation points in Hyundai to recommend? Or should I just turn this over to the lawyers?

Good news! My car is fixed and appears to be issue-free. I'm keeping my fingers crossed as I really do like the car.

The service manager told me that about a month ago when the repair started they only changed 2 of the fuel lines. This is in direct contrast to what the service rep told me - he specifically told me there are 3 part numbers comprising 4 lines and Hyundai had recommended all three be replaced. Apparently there is an interior portion of the line that can close a bit - for me it was only noticeable when aggressively accelerating.

A month ago I was told they performed the service and the problem persisted after the recommended work was completed.

I'm not sure where the ball got dropped but basically my car sat at the dealer for something that should have been a half-day repair. The lack of communication led me to file a lemon report with Hyundai and that might have brought focus to my problem.

If anyone else has this problem I would strongly recommend that you be very specific about all the fuel lines being replaced. Others on this forum have stated that their problem was resolved with the lines being changed.

If my car was parked at the dealership for a month, with no communication at all from anyone, I would certainly not be happy that they finally did their job after I threatened the company with a law suit. Unless for dealership or Hyundai paid for an equivalent vehicle during the time my car was sitting at the dealership service department, I would fully expect them to compensate me for the loss of use of my vehicle. Providing a "lesser loaner" does not make up for the loss of use of your car.

I wouldn't accept a happy meal from a high-end steakhouse either, that's basically what the "lesser model" is vs. the Genesis.

Hyundai is not ready to start a Genesis brand with dealer experiences like this. They can claim all the luxury brand ambitions they want - not returning calls wouldn't be acceptable even for a base model Elantra owner. Returning phone calls and taking care of customers is their only job - how hard is it to make sure that reasonable customers requests are taken care of in a timely manner?

The more I hear about issues like this, the more I have the feeling that Hyundai/Genesis isn't anywhere close to launching the Genesis brand as a luxury experience. These same dealerships will be dealing with the G80/G90 customers now, why would they suddenly start to treat these customers any differently?

Thanks for sharing your experience - my car is going in for a 7,500 mile service and several warranty issues on Monday, I am already bracing myself for the "we can't reproduce the issue" and other excuses ...

I like the happy mean analogy. I was given a lesser model as a loaner and was surprised that nothing was offered - they could have given a couple of oil changes with little impact.

I started a call log after the work was not completed in 1 day as promised. I've had a small number of situations in the past where a simple repair becomes a hostage situation - A rotor resurface and 4 new tires once took a dealer 8 days! Escalation to the Service Manager or GM usually works but in this case neither returned my call until 7 days later when I got a call from the Service Manager.

After the initial repair did not resolve the issue, I asked the service rep to call me each night and provide a status as to what they were doing. I asked that it be left on voice mail if I was not available. I never received daily calls, there were gaps between me calling and getting a call back and the rep never left anything on VM other than please call me back. This is what prompted me to send the proper lemon notification to Hyundai.

I've been in the service industry in the past and have found communication, or over communication, can have a major impact on how your customers view not only you but the rest of your company. In this was the dealership failed.

That all being said, I really like the car - I had a 2002 Lexus GS430 prior to this and consider the Genesis to be an upgrade. Good luck with yours!

marinakorp: Yes as UglyTuna said not everyone's issue was resolved with fuel lines at the time of my OP.

Finally took my car in yesterday and today they called to say they reproduced the issue and that it's a bad throttle body. FWIW I told them according to the internets it may turn out to be the fuel line, so we'll see where this goes. They also took care of the latest recall and had to call a tech line to kill the bad smell in my a.c.

They gave me a G80 loaner to use so all I'm missing is 2 cylinders for the next week.
