3.3TT Class Action Lawsuit: Pulsating Brakes

[StingerGTT]

yes I started having the problem around 4 to 5k

I’m in !

 

[ChaneRZ]

Yup I have had the same issue from 4K miles I have one of the original production stinger GT 2/18 I’m now at 45k have my 3rd set of rotors on the car they are now cross drilled and slotted and the car still eats them alive warps them like nothing I have tried multiple break in procedures nothing works they all just warp after a few high speed runs ( ya know what the car was built for ) I’m getting so sick of it. They need to do something.

New rotors and use the same Kia brake pads?

3rd set of rotors on the car

I was wondering the same thing. The pads are the problem, not the rotors.

 

[StingerGTT]

Put brand new pads from the dealer on there also With each set of rotors pads aren’t cheap I tell ya. Should we invest in EBC pads then ?? I figured brembo pads would be better.

 

[JTQ911]

Does anyone know if the G70 is having this issue as well?

It's almost impossible to understand how you could ask this question, unless this is your first visit to a pulsating brakes thread. The consensus is that aftermarket pads (or Euro-spec pads) fix the pulsating brakes issue; rotors are not and never have been the fault. The US pads are soft and quiet. And they melt when they get heated up. I must be a baby with my brakes, because I have 36K miles on original pads and rotors and have never had the first indication of rough brakes, much less pulsating in the brake pedal and steering wheel.

The G70 is reported to have the same issues as the Stinger. Again, not a majority of vehicles, only a constant few.

I think you also hold the mileage record for a set of OEM Michelin PS4s on a Stinger.

 

[WRXtoStingerGT]

I have to drop in here as well.

Car was owned for about five and a half months. 3000 miles in I had the dreaded pulsating braking issue that all 3.3TT Stingers seem to get... It was scary slowing down at any speed above 60mph...

I had to bring in the vehicle TWO TIMES within less than three weeks and less than 200 miles of driving.

They were able to fix the issue the second time, but, I am worried about this happening again. I understand that I should go and spend a few more hundred dollars on aftermarket pads and possibly even rotors but to me that is silly...

I am fine jumping into the band wagon for this class action lawsuit. I just want to make sure that I am covered and am safe. I don't want to have this issue a third time but if it happens I know I will have to fight tooth and nail for Kia to buyback the car or replace it BUT then we are back to square one.

It is FOOLISH that they keep "fixing" the problem by putting in the same improper parts that keep causing the problems.

I am fine biting the bullet and going aftermarket, but, I will then want Kia to cover some of the expenses if not all. I find this entire problem ridiculous and the ONLY reason I purchased a Kia in the first place was for the warranty.

I like my Stinger but I want to be able to drive safely without scaring myself nor my passengers.

This is exactly why I purchased drilled/slotted and bought stoptechs front and rear. I thought about taking the car in to KIA to have them replace everything, but I didn't want the same old. I knew they'd fix it temporarily, but screw that.

Having said that, the warranty for me isn't as good as I thought. What I mean, I can take my car in and get work done...but it's not as simple as "this is wrong, fix it". It feels like I have to "work at it".

Also, on a side note...I had the loud knocking sound coming from behind my radio. It usually would come up when I started my car. I have so little confidence in my KIA service department that I made an appointment and during the week before I was going to drop it off...the sound stopped. I decided not to go in for fear of them breaking something else or taking forever to figure out the problem that suddenly went away.

I think you also hold the mileage record for a set of OEM Michelin PS4s on a Stinger.

If for some reason you think that I am still on my original tires, I must clarify: PS4 rear tires were replaced at 18K miles (Indicated: with c. 5K on Nitto Motivo UHP A/S as part of that: this reduction fact I neglected to mention until I recollected and corrected the "18K miles on PS4" claim), and 22K on the PS4 front tires (again, c. 5K miles reduction of that for the Nitto Motivo tires).

That's still not bad. I probably could have squeaked another couple of thousand miles out of my rear tires, i.e. obtained the treadlife warranty of half for a staggered setup. But I was going on an extended road trip and would require new tires long before I got home; so, I replaced them a bit early. The front PS4 were definitely shot by the time I got back, c. 4K miles later.

I have read on here of a couple drivers getting into the 20Ks with their PS4 tires; but I can't remember who they were. And in these matters, all we have is a person's assertion (which, with myself as an example, can be mistaken).

 

[HDTurbo]

Well, I'd like to assert that this brake business is still decidedly unestablished as to true causality. If I've got a complete Brembo system, and like Merlin and some others, not having any problems described, what is really making the difference here?
Peace!

No, I had known that you replaced your Stinger shoes. Let's just say that you got about 10k more miles from your rear tires than I did. Fronts were well past 15k when I turned the car in. I just remember being amazed every time you mentioned the mileage you were getting from your tires (relative to mine).

As for brakes, I'll probably remain a sporadic contributor here just to see if any resolution or determination of the brake issues is found. I was told that my car might go back to Kia as a car they study, examine, and train on. It would be a perfect car to learn from.

 

[HDTurbo]

Nice they seem willing to learn! And the dealerships/techs are certainly not equivalent to the designers/engineers/builders. I'm gonna go out and heat my brakes up now!

1 - So if I purchase the better aftermarket front pads that everyone is suggesting on here then that is it? My problem will go away? In other words if using aftermarket front pads this issue should no longer occur assuming I am not beating my car on the track or running it through car washes after spirited driving?

2 - I am glad they are taking your purchased back car in for further inspection and study. It is a shame though how much Kia seems to fight back on owners of their "flagship" car that they have produced to break into the "big boy and big girl" adult market. They should be kissing our feet for taking a chance with this vehicle. LMFAO! I'm partially kidding. My family has owned multiple Lexus, BMW, Mercedes-Benz, Volvo, and Toyota products. Plus, I personally owned a 2014 WRX for six years. I took a shot and a chance with the Stinger ONLY because of the crazy good and amazing warranty that they were talking about left and right. We like to keep our cars for at least ten years. The Subaru was our only an exception.

3 - @HDTurbo you're in Saratoga NY. May I ask, since I am currently in Yonkers NY for the next six to twelve months, if you think running all-season tires on my RWD Stinger will be safe living in upstate New York? This is my daily driver and I will be commuting into Brooklyn, Manhattan, and Queens for work five to seven days a week and must be able to get to work regardless of the weather conditions. Thanks! <3

1- I actually paired aftermarket pads (Stoptech Performance Street) with new rotors (OEM Kia) and the problem returned for me. For most it solves the problem. I have always thought there was something in the braking system itself though. This would explain why Kia doesn't have a fix and why it doesn't happen to all drivers. Many times it felt like my auto hold was working when I had the system turned off.

2- I'm actually wondering what Kia will do with the car. I am going to periodically check the VIN to see where it ends up.

3- As a non-snow driver I would try all-seasons with AWD but for RWD, get a set of dedicated winter tires and rims. There are some good videos that show what a difference winter tires make even on RWD cars. It will convince you to get winters. By all means though listen to the NYers. Actual experience beats hunches and feelings.

 

[HDTurbo]

Agree on the dedicated rims/winter tires for RWD. And make sure you get out an practice in as many snow/sleet/freezing rain conditions so you get a decent feel for how the car behaves so that you can be somewhat confident in those conditions. So many drivers don't and don't learn until after they're in the ditch! And/or are so friggin' scared that they become a hazard themselves. And stay in the appropriate lane on the multi-lanes... When I close in on a Prius in the fast lane going 30 with the hazards on...urge to kill rising!!!!

 

[StingerGTT]

I haven’t tried after market pads yet that’s my next step if that doesn’t fix it we all need to do something cuz it’s getting tiring and unsafe 3 pairs of rotors for me I figured cross drilled and slotted would fix it but it hasn’t, I do ALOT of “spirited driving “ lol cuz ya know that’s what the car was built for , it’s not a putt putt car like a civic so if the money I dump into the pads now doesn’t work I’m going to talk to the dealer and see what’s going on since I know the service manager very well and I was also one of the first buyers in early 2018. Bust my balls (other posters who are better than me somehow) if you like but it is what it is I didn’t but a civic EX I bought a Stinger GT. KIA stand by your flagship car that has a great top speed but can’t stop!!! (without almost killing me) I have to downshift most of the time to save my brakes ...... brembo????? that’s all I’ll say

 

[Toddasaurus]

Does anyone know if the G70 is having this issue as well?

Yes. Although there was a Dynamic trim that included the Euro spec brake pads which do not have this problem.

I'd recommend just machining your stock rotors, then getting some aftermarket pads. Hawk makes pads for our cars, front AND rear. It's what I did.

 

[WRXtoStingerGT]

1 - So even if I go with aftermarket pads that are superior than the OEM pads AND do the proper "bedding" procedure there is still a chance of this problem returning with my car shaking and the brakes thudding/shuddering on the vehicle? That is insane. What a joke! lmfao!!!

2 - I am seriously considering running winter tires year round. How bad of an idea is this? Mind you... I am an extremely cautious and safe driver. I never speed or race on sharp turns, steep hills, or whenever there is inclement weather. I have experience driving in snow/rain when I used to live up north before but had an AWD car with all season tires. The only reason I am considering winter tires year round is that it will be much easier for me storage wise (since space is extremely limited where I am right now) and since I do not really speed I should not risk a blow out in the warmer weather. Thoughts?

Don't run winter tires year round they are not made for warm climates. They'll be incredibly sloppy in spring and summer as the rubber compound is made to be more compliant at very low temperatures and they get way too soft in 60+ temps.

From what i hear there are dealers and tire shops that offer tire storage for tire swap outs, you might want to look into that option if space is at a premium for you.

as an aside, I always ran 2 dedicated sets of tires even on my old WRX. AWD is no substitute for proper tires and, IMHO, most all season tires really should be called "no season tires"
