2011 4.6 Brakes are USELESS

[Stunamar]

I have 27k miles on the car bought it new and this will be the 3rd set of front rotors. At 17k they warped badly but were cut by the dealer, 3k miles later warped again.

At this point I think it's probably best to go with an aftermarket set of rotors. Maybe I'll upgrade the pads too in an effort to increase stopping power being the overall brake feel and performance completely suck.

I have to say the brakes on my 2008 BMW 550M are some of the best I've ever had! Better than my BMW 745, Audi A4, Porsche Cayene S and the Twin Turbo. The brakes on my wifes's ML500 are great too.

The Gensis brakes are almost as good as the coaster brake I had on my bicycle when I was young.

Any suggestions? I would prefer to stay away from cross drilled and or grooved rotors. While they may look cool thats really about they only realized function/gain unless the car lives primarly on the track driving at or near the limits on a regular basis.

I actually think the brakes are fairly good on the Genny. Have about 20K and no problems yet.

I've got close to 40K miles on my 2010 4.6. Just had the tires off so I took a good look at the rotors and original pads (actually removed the front pads to inspect them). Rotors are perfect, and I still have WELL over 50% left on the pads.

To have the problems you are describing there must be some additional issue with the suspension. I'd be talking to the dealer.

I have a 2011 4.6 with 71,000 miles on the original brake pads and the braking is as smooth as when the car was new. Many on this forum have many many miles on their original brake pads. The car magazines have also given the brakes high marks. The reason rotors warp is usually due to very high temperature. Are you the only driver? Did you purchase your car new?

2009 4.6 with 37k miles and original brake pads, rotors. Florida car. No issues here.

Having a dealer shave the rotors was your first problem. Shaving = less material to absorb and disperse heat. Which = easier warping.

From experience of forum members, rotors and pads have not been a problem. Sounds like your issue is the original set of rotors were defective, and cutting them was is not a cure. Hyundai should replace them under warranty.

Just had one panic stop(ABS engaged) in my 09 4.6, and tried the brakes 30 miles down the hwy, and pedal almost to the floor. I've read there may be an issue with the ABS module...but in all honesty, if that is the case....this car is going away soon. Never had that happen in any other car.

Man, I miss my 04 CTS-V.

 

[Philth]

GM? No thanks.

 

[darrell]

My experience is the brakes are very good on my 2010 Genesis Tech/ w 18' wheels.
I have owned several Lincoln town cars that warped rotors seemed to be common problem.

Does your driving habits or environment require a lot of hard stops or constant braking?
Are the rotors getting wet after a hard drive? An Example could be visiting a car wash after rotors are hot.

No offense, but do you realize how silly that sounds on a Hyundai site? I know the strides Hyundai has made in recent years....but still....

 

[topspeed]

I have 23,000 miles on my Genesis. No problems with the brakes whatsoever. From day one I thought they were the most stout factory brakes I've ever had on a car.

 

[Vince2]

I've found fault with our Genesis in several area (Who's extremely happy with the suspension?...Is there an owner crowing about the ride?) BUT the brakes are excellent! It is the sole area that I have unreserved praise for. Luckily I haven't had the soft pedal or faulty ABS (and I wouldn't even be surprised if I get that issue) but until problems occur the brakes are good.

I came from GM cars (many of them) and Hyundai is light years ahead of GM and has been for the last 10 years. In addition, GM has had the worst brakes in terms of wear are reliability for the last 30 years. I used to always scrap the OEM brakes and put on something from Summit Racing, cause even the cheap stuff from Summit, was better than OEM GM brakes. It is humorous how many different cars with different power output GM used the same tranny's in. They couldn't figure out why the same tranny (4T60-E ) in a 2.3L GM vehicle also used in their 4.9L Caddilac DeVille would blow tranny's???

My R-Spec brakes are equal to or marginally better than my 5-Series brakes. Great feel, totally progressive (unlike our Volvo brakes which are still very good), great stopping power, no dust, and very little wear on pads or rotors after 20,000 mi.

There is definitely something wrong with the OP's car or ??

I agree; I have owned just enough GM cars over the years to forget how bad they are when I buy another one.

I bought a 1991 Camaro RS brand new, and it had issues from day one. T-tops leaked air that could never be fixed, radiator fan (again!) would work when it wanted, and paint quality was terrible. Before that, it was a 1979 Camaro Z-28; there is not enough space on this forum to list all the problems that car had.

My last GM was a 2006 6.0L 6-speed SSR that i ended up selling with just 17,000 miles. The radiator fan went out, water pump failed, interior door handles would come off in your hands, and various interior trim items would just fall off the car (truck). My biggest fear was that the top would quit working, and no parts would be available to fix.

When I say "my last GM", I mean it this time!!

Interesting sidenote: while back east last summer visiting my daughter, son in law and grandsons, we had a 2012 Malibu as a rental. The car had less than 900 miles on it. When we stopped for coffee on the way from the airport and went to leave, the car would start, run rough, and not accelerate. After restarting it a few times, it would run fine. Stopped at a rest stop, same condition.

Either I need to take this as an omen to buy a lottery ticket, or stay away from anything with a Bowtie on it.

For the last 10 years? You could make an arugement for the last couple of years, the GDI engines in the Sonata make great power and efficiency...but other than that...10 years ago, Hyundai vehicles were still regarded as, to put it bluntly, pieces of....

My modified 2000 Regal GS(stock brakes), never had even the slightest brake issue, and that is with about 170K miles, many in quarter mile increments.

I do agree on the transmissions... the 4t65E in my GS is the same trans all the FWD drag cars use in their 1000+HP applications. Of course there are a few upgrades they make.

I like my Genesis...but my braking issue with the car is making me want to trade it in on an 09-10 CTSV. I'll give the dealer a crack at fixing it. If they give me the BS about not being able to replicate the problem....I will try to work out a swap with the dealer for something else.

I had a 2003 Elantra that I bought with 33,000 miles and at 116,000 problem free miles, and my GF at the time (now wife) had a 2006 Sonata for 3.5 years and it was also a great car, so I decided to trade in the Elantra for the Genesis. I only bought the Elantra because I wanted a newish vehicle with low miles at the time without spending tons of $, and because everything on the internet at the time rated the car very highly....boring, but nonetheless, reliable and a lot for your money. Now with the Sonata - 2 Sonata Generations ago is what got more people noticing Hyundai cars, even though they weren't sold on them yet. That takes time even though the product was descent. Then the 2006 Sonata came out and they became a dime a dozen after 1 year.

My grand prix I had I sold with 133,000 miles and it's 2nd tranny was starting to act up (as usual) and I also had to put a new engine in it $5,000 in 2000. Bonneville I owned 2 tranny's and brakes, Celebrity wagon, 2nd tranny toast at 103,000 miles and I literally could go on and on. Some people can buy the most reliable cars in the world and still have problems of course.

I do agree the CTS-V is pretty bad ass and really the only product from GM that pulls any interest for me.


One of my favorite comments in the forum from Mr. TJParks01. I know where he was coming with this one, as I looked in the G37 and GS460 (and others) prior to my Genesis purchase.

Hyundai wasn't even on the radar screen before I bot it. All the cars I looked at had some issue (compromise). G37, hotrod nice car, back seat is kinda small. 328, iconic, they put the cupholders where? same as G37 kinda small? ES 350, you want how much for a Camry with lipstick? Accord V6, good car, zzzz, front wheel drive, zzzz. Anything american, clusterf&*k management, sorry no interest. Hyundai, hmmm...

Autoweek said they were some of the worst brakes they had ever seen and still gave it car of the year award. If you do any spirited driving on some twisty roads you get brake fade after about the 3 heavy braking for a corner. I think slotted or drilled rotors and ceramic pads would help. You may have to go to a big brake kit to get the car to stop as good as it goes.

 

[jnc2000]

you should have 4 pot calipers up front, single pot rear (front vented rotors, rear solid)... a more aggressive pad / rotor combo may help.
