Accumulated G70 issues

[TinsleyC]

Basically get up to about 80-90mph. Slam on the brakes as hard as you can till you come to a complete stop Then next step is the hardest. Drive for at least 40 min to let them cool all the way down without touching the brakes at all.

If the point of driving 40 minutes is to let the brakes cool, I'm pretty certain they'll reach 99% of "as cool as they'll get" within a few minutes. There's a lot of air movement around the brakes when the car is moving, they won't stay hot very long if not being used.

Ya you just have to make sure so they do cool all the way so you don’t restart the issue that causes vibration immediately. If you let them cool completely off before using them you should get about two months ( best case senator) until it needs to be done again. I tend brake hard a lot since I usually get into a few freeway roll races a week with other fun drivers so my brakes tend to stay clean unless I get them super super hot

I agree with @TinsleyC that 40 minutes is too much. I've re-bed my brake pads before many times and with 10-20 minutes without braking is enough for let them to cool.

Concerns - Popping/Creaking Noise from Sunroof

Poster "Kamauxx" solved his issue but with 32 pages of the thread there have been more fails than success. May be due to more than one issue.

Dark Chrome surface imperfections appear in relatively short time after purchase. Despite interim remedies a replacement by dealer seems to be the best repair. Mentioned a number of times on the board.

I had one issue with my sunroof which the dealer took care of quickly. The auto part of my sunroof switch wouldn’t work properly. Just needed to be recalibrated As far as the brakes vibrating it’s from them getting dirty from the oem brake pads. There is a free quick way to clean them but the first step is quiet violent lol. Basically get up to about 80-90mph. Slam on the brakes as hard as you can till you come to a complete stop Then next step is the hardest. Drive for at least 40 min to let them cool all the way down without touching the brakes at all. I haven’t done it yet myself but my brakes don’t my vibrate much since I tend to not have to brake hard much on a daily basis

I'm a bit of a performance nut, an automotive enthusiast and one who knows a good deal of the performance aspects of a car. To expect a "general consumer" of a car to perform this break bedding process of an above legal speed abrupt braking procedure, then a subsequent cool down of the brakes is not only foolish as an expectation on the manufacturer's part, but is also inherently dangerous; most drivers just aren't that skilled.

Let's also reflect the fact that I've seen no official literature from HKA stating this procedure is necessary in any way, shape or form. The manual simply states commonplace break-in procedures, not this. Sounds like a poor choice of brake pads by the OEM to me.

Pulsating brakes happen on many cars. The first time I saw a solution for it was about 10 years ago. The solution touted back then was to perform the hard stop from at least 70 mph but to do it three times as fast as you can between. No, you won't find it as the solution in any manufacturer's manual. Never tried it so I don't know if it works. Doubt there are many places to safely do that, maybe at 3 AM in Nebraska.

You say it is a poor choice of brake pads by the OEM. That may be a factor but I think the driver may be a factor too. My neighbor never had it but every car his wife drives regularly does. Aftermarket as well as OEM pads.

There are several brake bedding recommendations online that are written by people who are in the business. They outline procedures that are much safer.

The break-in procedure is crucial to making sure your break upgrade performs optimally.

The attached PDF from Centric brakes gives great advice. Please don't slam on your brakes at 90 mph.

Bedding in new pads is one thing, but I think Revvmedia's point is that this is not something that should have to be done on a new car, especially multiple times, and not something that many customers will know how to do properly and safely.
Given the number of people on both this forum and the Stinger forum that have had brake vibration issues, along with the automotive magazines that have tested these cars, I think it's pretty clear that Genesis didn't put on pads with the proper material.

That's pretty much what I wanted to state. If you bought something exotic like a Porsche 918, Ferarri LaFerrari, then sure one would expect the expectations on how to handle a track focused vehicle will differ than a run of the mill commuter. The Stinger and G70 (as well as other Genesis cars) are not track vehicles, are not advertised as such, and representatives within HKA have stated they are not track cars, so to have to re-bed pads repeatedly sounds wrong on a daily driver, I would expect that on a track car and would then not complain about it.

I always knew brake pads had 3 properties which you could only choose 2 - quiet, excellent stopping power/fade resistance and low dust. Rarely does a pad have all 3. It seems having to re-bed might be a fourth aspect I never considered.

It sure looks that way. I had the same issue with my Infiniti G37, had the rotors turned multiple times and the problem kept coming back. I finally replaced the rotors and pads with Centric brand parts and the problem disappeared. I'm sure it was the OEM pads that kept causing the issue because it's rarely warped rotors as many people think. Turning the rotors is not fixing a warping issue, it's simply removing the uneven layer of bedded brake pad residue.

When my brakes eventually need replacing I'll probably go with Centric again.

I've had my G70 sports with 6MT for a year and 4 months now. I've accumulated over 32,000 Miles (52,000 KM). I'm happy to report that so far, I've only experienced one quirky mishap with the sound system. For about a day or two, the speaker in the passenger's door buzzed/vibrated, even at very low volume (I listen to audiobooks mostly - I know... very lame...). But the problem corrected itself. Maybe my 18 year old son took it for a spin and gave it a good high-decibel trashing, as youngster are want to do... lol

My brakes (Brembos) are still above 5mm. This seemed to surprise the service director at the dealership. I explained that my 18 year old racer doesn't get to drive it all that often.

The only other issue I have is with the red thread on the driver's seat bolster is wearing prematurely, and is showing signs of discoloration. I try to be careful entering and exiting the vehicle, but I guess at 6' 2'' and 240 lbs, there's only so much daintiness I can add to the proceedings.

Congratulations on teaching your son to drive and appreciate a manual transmission. Does the Cdn connected app have geo fencing alerts, speed alerts and the other features of the US app?

^ +1 on the younger folks keeping the manuals alive. i know at least my daughters will be doing the same when the time comes. i love this meme but some young 'uns beat to their own drum:




as for the brake wear, i am keen to hear what the realistic life expectancy is for the Sport Pads on the 6MT trim. i'm only at ~11k kms after ~18 months (how is AGD at 52k kms!) so everything was fine at the first dealer service. i've said this before, but i'm leaning towards replacing my sport pads with the standard 3.3T Sport ceramic pads when mine are done. the brake dust is a bit much to deal with when i seldom use the full capabilities of the true 6MT Sport Pads. based on AGD's feedback it sounds like i'll be waiting a while to do this.

just so you know, those ceramic pads are prone to brake shudder issues. Im light on my brakes and dont push them hard (slow in fast out) and I got brake shuddering from just one slightly heavy stop down from 75-0 (no abs, no tire squeal) and I had to sit still for no more than 15 seconds while I waited for traffic to start moving. Thats all it took, and even though they 'fixed' the issue by turning my rotors....obviously there is a defect in the pad and it can come back

For sure! I have 4 children, and they will all learn to drive manual, that is for certain. In fact, my son's car is also a manual transmission. I got him a 2008 Accord with 5MT, last summer. I was extremely pleased when one of his criteria was that his car be manual.

That's a really good question! I had no idea that the connected app could do so much. Let me check. There doesn't seem to be that much information on there. I've attached a screenshot of what we get under the ''driving information''

I've always loved that meme.

As for amassing so many kilometers... I live far away from work, my round trip is over 130 km's (about 80 Miles for my American brethren). It's a good thing I don't work Monday to Friday, but our work schedule is mostly 12 hour days (or nights) and I can carpool on certain of them. Added to that, last year my oldest aforementioned progeny with the penchant for loud music was in a highly competitive volleyball league. I live close to Ottawa, but his weekend tournaments brought us to Kitchener/Waterloo, Toronto, St-Catharines, Kingston, Limoilou Québec… etc...

Although now, if you notice my previous reply, I put just 434 Km`s in the last month! I bought a 2006 Toyota 4Runner about 2 months back as a second vehicle/winter beater, so my Genesis has been given a bit of reprieve. I hope that over time (in about 2 years) the mileage will reflect normal years of ownership! lol

The service specialist did mention the possible cost of pad/rotor replacements when I brought it in for my last service and lets just say that I will be sourcing parts and doing that work myself. Another life skill I`m passing along to my kids.
