2015 Genesis Reporting Issues/Recommendations

File a complaint with Hyundai and get a claim number then contact your dealer. Others have complained about a knocking noise when making fast turns with the 5.0. They could be related.

I have posted on that a couple times with the 5.0, it's the only vehicle I experienced it with and it was only under hard acceleration when making turns...not saying it doesn't do it other times but hasn't for me. The 3.8 HTRAC did not exhibit the same behavior and I haven't driven just a RWD V6 yet so I can't comment on it. I definitely would not delay in getting the issued addressed, if it is the same noise then something is not right with these cars and it needs to be fixed.

What does the knock you heard sound like? Mine sounds like the seat belt buckle knocking against the inside hard part of the car. It doesn't seem like it's from underneath the car or something.. ?

To me the sound is coming from the right rear and so did it to the service manager, he forwarded that information to someone higher up in Hyundai but still no answer back. It's a really loud knock and almost sounds like the underside of the car is hitting something/bottoming out... but obviously it's not or there would be damage to that area. It's not isolated either as we experienced the same thing in two of the V8 Ultimate's on the same corners/turns from a standstill, both times under hard acceleration. When the vehicle was already going 15-20mph we didn't notice it. I'll try over the next week to duplicate it on straight roads and report back.
 
Could the sound in simplyaddos case be coming from the new PreSafety seatbelt system in the 2015 Genesis?

Perhaps the system is either noisy or very sensitive and producing a sound from the seatbelt area in the pillar when the sensors notice a shift in vehicle direction/acceleration?

Although she has not mentioned anything, I'll ask my wife tonight if she has noticed any knocking sounds in her car as she tends to be quite sensitive to these things.

Were the turns to the left or right when the sound was coming from the right rear? I can imagine a scenario where the traction control was kicking in on the inside tire on a RWD. I don't know why that would make a knocking sound, but they could be related
 
Right turns is when I notice it, but it shouldn't be making a crazy noise like that even if it is traction nanny kicking in.
 
I don't disagree about it not being right. I just think that system is where I would focus my search for the source. It makes sense that it happens at low speed while turning. That would be the easiest time to light up that inside tire. Plus, you said it doesn't happen at all with the AWD.

Have you ever experienced the heavy pulsing of ABS brakes in snow? Any chance it might sound similar? that's the most likely thing I can think of.
 
Okay, this is really bothering me. Ever since I got my 3.8 2015 Genesis a week ago, i get this random knock noise, from what seems like the rear passenger side. It's random because it is not exclusive to when taking turns or hitting potholes, nor when driving at a particular speed. Sometimes just changing lanes, and it can be heard.

I first thought that the passenger seat buckle was knocking against the car, but it happens when my wife is seated with her seat buckled. I checked the trunk and there is nothing that could be wobbling around.

Last night I asked my wife to sit in the back seat to see if she can identify the location of the sound. Strangely, she said that once you sit it in the back seat, it doesn't seem like the sound is coming from the rear anymore; rather up ahead.

Anyone have any ideas what this could be?

Could be lose sway bar or sway bar end link, best to take it to the dealer.
 
In my case, I notice the knock even when I am gently coming out of the parking under my apartment, which requires the car to drive down a foot high ramp (at less than 8 km/h). Also it doesn't get progressively any louder if I hit a rough patch of road or a pothole.

In any case, I will be visiting the dealer on Saturday to get my wings badge installed on the trunk. I will speak to a tech then. Let's hope this is a quick and easy fix.

UPDATE:


On the 3.8 the tires should be 33psi and the 5.0 says 35psi on the plate inside the door. The 5.0 we had on the track was only @ 44-46psi after many high speed laps throughout the day in 95 degree weather.

I spoke with the service technician and the reason the tires are overinflated is to stop dead/flat spots from happening during shipping and while the cars are sitting on the lot. Before they deliver/sell the car they are dropped to 34psi cold per the pre-delivery checklist. The HTRAC I had wasn't PDI'd yet as it had only come off the truck the night before, therefore they were overinflated...yet still within the allowed cold rating pressure.
 
UPDATE:

I visited the dealership on Saturday to have my rear wings installed and to have that knocking sound looked at.

After a drive with the tech, he got out and looked at the trunk from inside. His initial diagnosis was that the trunk latch was not aligned properly.

I left the car with him and came back after a couple of hours when he called saying the problem has been fixed. I took a drive with him and couldn't hear the sound anymore. I was delighted. I dropped him off and when I drove back home, I heard the sound once again. :(

Since then, I have heard the sound again, but less frequently. So something has changed for sure. I was wondering about the trunk latch. I always felt that the trunk door wouldn't close easily. I had to almost half-slam the trunk door to get it to latch.

Any of you folks think these 2 are certainly related? Anyone care to shed light if indeed the trunk door is harder to close, than other cars? (I am comparing it to my previous Optima 2011)

The only one's I have been in are Ultimate models including the 3.8 HTRAC, they have the power open/close trunks which seem to close with no issue. Now one thing I did notice is the front passenger door seems to take excessive force to close, almost like the cabin is possibly over-pressuring making a light close of the door difficult.

Which is why the soft close doors readily available overseas would have been welcomed and add to the luxury feel the car strives for. A small, but important feature which can go a long way to defining the car.

I noticed this on the 5.0 at Rick Case on Saturday. I had to give it a good slam to close completely. Can you post up those items I asked about in another post regarding which features need to be set and which ones are automatically on.
 
I've got a 2015 3.8 HTRAC. I notice the same kind of popping/creaking noise. Generally, it happens when the chassis flexes, like you mentioned, in a driveway, or really bumpy road. I'm going to set up a dealer appointment.

However...I noticed if I open the sunshade on the pano roof, and push UP on the front glass, I get the EXACT same popping/creaking sound. I think the noise is from the roof. I've tried adding a small amount of "weatherstrip lube" to the weather seals around the roof; which didn't change anything.

What is frustrating is, there are times when the car is completely silent, and then times where I drive over the same patch of road (or in some cases, just turn a corner), and it will always make that noise. Also, I noticed with the roof full open, in my condo parking lot, where it ALWAYS creaks...it doesn't do it with the roof open; hence why I think it's something with the roof.

My bet: It's a bad or missing weld on the body, causing a couple panels to pop under chassis twist.

I did under the likes section, here they are:


LKA (Lane Keep Assist) + Lane Departure: On till you turn it off.
Blind Spot Monitoring: Always on in the mirrors, can turn on/off for the HUD.
AEB (Autonomous Braking) Always on.
Driving Modes (Sports etc.) Must be set again each time you start the car.
Smart Cruise: Must be set again each time you start the car including distance.
Traction Control: On unless you turn it off (might reset?, will check).
Rear Cross Traffic Alert: On (not sure if it can be turned off but will check asap).

I actually have that issue with the driver's side of the door. Most of the time I have to open and close it again.

There is an option to turn off both the AEB and the RCTA in the gauge cluster menu.
Traction control turns off in two stages (trac off then trac and stability off if you hold it). Traction control comes back on when you restart the car.
The car also always defaults back to auto-hold off (I dislike), and normal driving mode (ambivalent) on restart.
