Noisy Suspension

Hi Dandufunk,

The only aftermarket motor mount available is the lower mount. SXTH has that available. The mount that was noisy for me (and many others) is the passenger side (or upper mount). R1600Turbo investigated that the GTS N-Line mounts were the same dimensions as they are in our car, and I decided to get those, since they fit and they were technical and upgrade.

The GTS N-Line mounts are more rigid (there was some info posted in the N-Line Motor Mounts Thread by R1600Turbo). I ordered all three (Upper, lower and transmission).

I know this is technically a warranty case, but I chose not to go to the dealer, as many with this same situation have gone only to have time wasted and not resolution. Plus, I've always had bad luck with dealers (the get the car back with more problems).

I changed the upper mount and went for a test drive and the noise was finally gone. It was such a relief to finally drive a nice an quiet car. I then change the other two mounts.

Over all, I do feel that the motor is held more rigid. I'm tuned, and when I installed my tune, I did notice more engine movement as there is more torque. Also, I feel a bit more vibration in the cabin. The steering wheel has a tine amount of vibration. I've been pretty sensitive with car, paying attention to noises and vibrations since this clunking noise started. So, I can see and feel the difference. It's subtle, but improved.

If you have clunkiness coming from your car while turning right and when it's colder outside, look at that upper mount (passenger side motor mount). It's most likely that, that is causing the noise.

I think what Hyundai did was that they just retained the motor mounts from the NA version of the car, and then realized that the 1.6 TGDI engine produced a bit more HP and Torque that the mounts were not up to the task of maintaining.

With the next chance Hyundai had to improve the mounts came with the introduction of the GTS N-Line. I also know that for the ES there was an updated part # for that motor mount. I can't confirm if that part # corresponds to the N-Line motor mount as being one in the same.

Hope this all helps. Thanks.

Hi Dandufunk,

Sorry for all the spelling mistakes. I wrote this at 530AM this morning! I was re-reading it! Both R1600Turbo and I have changed all three mounts from ES OEM to the N-Line. His car is 6M and I'm DCT. Mounts fit no problem.

I saw the you've commented on the N-Line motor mount thread here, and are aware of it. Also, both of us made some pretty major write ups on the ES of NA group on facebook. You should check them out if not a member.

I had started a thread on the clunking noise and tagged all the people with the same noise under the same conditions. They (and I) had posted videos of the noise. You might want to check these videos as well. I know in this thread there is a video or two posted as well.

I understand the frustrations of mechanics and dealers trying to diagnose this. As why would you be looking at a motor mount on such a new car. My car started making noise at 18,000 KMS! Not much mileage!

What's funny is that the noise started at the first right turn I made after installing an upgraded aftermarket rear sway bar. Now, this could be just a coincidence, or there was an overall balance upset with the car that lead to the mount making noise. I know there are other owners who have the noise with and without upgraded rear sway bars. Perhaps, either way it was going to happen, just sooner or later depending on the stresses put on the car in day to day driving.

I did notice in the press release of the N-Line that there are comments about retuned suspension with spring rates, sway bar diameters and together with stiffer motor mounts, creates a better balanced and handling package. So, no sure if the upgraded rear sway bar caused an already prone motor mount to act up with this influence? Or it was just destine to make noise at some point or another.

I've since then upgraded my rear sway bar with the Veloster/I30N rear sway. It's a direct bolt on. TBH, it's the perfect balance. I don't track my car or anything, so this upgrade is perfect.

I'm in Canada, so I understand the $$ conversion. I know the the Australian and Canadian $'s are fairly close (why I bought the GFB BOV). I ended up getting my mounts and N sway bar from Albert. Even in Canadian $'s it was very reasonable. I would say it was cheaper than me going back and forth to the dealer and wasting my time trying to resolve the noise (as others have) and only to have other things screwed up...

I was thinking about going the SXTH lower mount, but I went for a ride in a 2 Gen Veloster with it, and it was too much for me. We had incredibly shitty roads here in Toronto and area, and the car is already stiff. Didn't want the added vibrations with that. If my car was a weekend car and just for pleasure and tracking, then I would definitely have the SXTH race mount on.

Hope this all helps.

FWIW, I just had mine done at Capital Hyundai in San Jose, CA. First attempt replaced the Insulator Assy-Strut, Pad-Front Spring, Bearing-Strut. Still there. Second attempt they kept the car for a week and replaced the passenger front engine mount solved!

That sounds bad, but I'd like to give supreme props to Ken N at Capital Hyundai and to their service team in general. Yes, it took two tries. But the entire time they were professional, courteous, and provided me updates as to the timing, status, and when work was done. This was done over text and email. After all the complaints on this forum about some Hyundai dealerships having poor service departments, I feel obligated to let you all know that at least in my case, Capital Hyundai was awesome.

I should add that they provided me with an unlimited mileage Elantra GT Sport 6MT as my loaner car for the week. I kept trying to return it so as not to drive a loaner and they kept telling me - "Just drive it and don't worry. We want to fix your car properly." So, I put about 300 commuting and general purpose miles on the GT Sport... Here's my evaluation of the GT Sport 6MT:

• Steering wheel - ugh, love the ES D wheel!
• Red trim in a number of places...uh, not my cup of tea
• Handling - for my style of driving no difference
• Acceleration - seems to pull more linearly, which was nice but not so different as to warrant a desire to change
• Sound - even more muted than the '17 ES and not as engaging
• Dashboard infotainment display/industrial design - F'n UGLY and poor. First, slapping a display on a dashboard like that is lazy design. It's rampant in the industry and just poor. Second, the thing is perfectly parallel to the front of the car. Meaning it's not angled to the driver. Why the **** would ANY dashboard element meant for the driver accommodate a passenger's wish to see? Answer, it shouldn't. The lack of angle in the display creates a lot more glare. I wasn't looking for it, but it was noticeable every, single, time I drove the car.
• Shift knob - like!

Overall - Much prefer the '17 ES 6MT over the '19 E-GT Sport.
