2019 Turbo S4 Brake Problems

Hello all,

I am posting this ad to see if there are others, and or save others from major headaches / wasted time / waisted money.

Since new my turbo S4 has had a weird brake pedal feel. Basically when you apply the break the brake pedal itself modulates/pulsates up-and-down. It would almost make one think that you have warped rotors and you are feeling that in the foot pedal...

I have had my razor in at Ride Now on and off for the last 4-5 months trying to resolve. The dealer has been great trying to resolve the issue however they have been unsuccessful and Polaris has a problem they are not acknowledging or have not let on that they are trying to figure out. At this point and nearly 5 months later enough is enough.

The pulsation in the brake pedal is a major safety hazard. It creates a very unpredictable brake feel. When the brakes are pulsating the weight of the vehicle lifts and drops, lifts and drops. Not good when you can’t keep the weight of the vehicle planted down on the tires.

At first the dealer thought they had it resolved by determining there were a couple missing parts (hub related) that were causing the problem but soon found out once those were installed had nothing to do with it.

Next they changed rotors and caliper brackets. That two did not resolve the issue.

On another visit they actually swapped all four hub/brake assemblies from another turbo S to see if that would resolve the issue. That did not.

I asked if any of the other turbo S4’s had this brake pulsation issue and as expected was told they did not.

Fast forward to a couple months into all of this troubleshooting and as I walk through the show room I noticed that there were ZERO turbo S (2 or 4 seat) RZR’s on the sales floor. Kind of weird for the largest ride now dealer in the valley to not have one ??? Of course it is.
Now fast forward to my most recent visit back to drop off the vehicle for the same issue after being told it was resolved, I took another stroll through the largest show room only to find it packed full of every type ATV you can think of with the exception of the RZR turbo S.

This time I actually asked a couple of the salesman if I could see one because I have not spotted one on the showroom floor for over a month and they let me know that they have been in such big demand that they cannot keep them in on the show room however, they did have some at the warehouse ????
Once the two salesman told me that BS I then let them know that I was currently an owner of a 2019 turbo S and inform them of the brake issue I was having,,, and that was continually being unresolved only to see their eyes widen and their body squirm as they obviously were prepped in sales meetings of this issue and what to say should somebody come in and request their most Beast like RZR by Polaris lol!

Anyway I would like to close by saying that the dealer has been reasonable in their attempts and communication however enough is enough and I still have a very expensive ATV that I have been unable to use for nearly 5 months. Monthly payments, insurance, and multiple missed recreational trips. I have just recently received verbal acknowledgment from Polaris representative that they would like to help offset some downtime but have yet to receive anything. TBD...

I encourage you to take your turbo S (2 seater or four seater) out for a test drive and see if you feel the same pulsation on the footpedal when applying the brake. If you do, please contact me as I would like to start connecting all of us and see how Polaris plans on making good buy this flawed brake system on the Turbo S.

Re: 2019 Turbo S4 Brake Problems

Frank, a friend of mine received a recall notice. Is there truly not a fix yet?

Spending money I don't have on things I don't need to impress people I don't know.

Thank you for reaching out. This has been frustrating to say the least. With that said the recall notice you are referencing was for small clips for the brake caliper pads and was performed on my vehicle first thing.

Totally unrelated. Actually just got off the phone with my case representative at Polaris and they are currently scratching their head and working with my local Polaris dealer trying to figure this out. I will keep this thread updated as we go but at this point Polaris is well aware of my problem yet you wouldn’t know it by speaking with them.
I think the issue is just now starting to sink in with them by the sounds of my recent conversation.
Like previously mentioned they have replaced all four corners of my turbo S with another and the same problem occurs,, which means the turbo S they remove the components from has the same issue and again is most likely why there are no turbo S fours in the show room.

Again if anyone else reads this and has a turbo S4 and perhaps even the two seater which I’m not sure if has the same exact brake system on it as the four seater’s are fairly large. But please test drive your vehicle paying close attention to your brake pedal feel as you apply pressure and if the pedal pushes back at you on and off you have the same problem.

Re: 2019 Turbo S4 Brake Problems

I have 1400 miles on my S4 now and haven't noticed this. I'm pretty sensitive to this with my vehicles' brakes and bought a brake bleed kit last weekend because I didn't like the feel of my Acura's brakes and redid the fluid so it would feel like it was back to OEM specs. I will take it for a spin when I'm back home to confirm.

I do recall seeing a notice on the break-in process not to use heavy brake pressure for the first 50 stops or so if I remember. The S4 has larger brakes than the 2 seater I believe as well.

Yes I followed the recommended break in. Basically a bedding in process for pads/rotors. But even assuming I messed that up, the dealer had checked all rotors/pads upon 1st trip in for reported pulsation. They found no issue with rotors/pads but still replaced just to see if it would make a difference. It did not.

I hope yours does not have the issue. Mine can be felt pretty much from braking at any speed but the problem becomes more noticeable from 35mph and up.

Will look forward to hearing your feedback.

Re: 2019 Turbo S4 Brake Problems

I took my S for a spin. I did notice some slight modulation braking from high speed on the street. I didn't notice it on the dirt. One challenge I had was separating the aggressive engine braking from the actual braking. I don't have a steep enough hill to try this in neutral.

The braking felt almost like the tires were slightly oval. I will keep monitoring it to see if it gets worse.

I have the exact same thing on my turbo s4. I bought at Abernathy's in TN. I Drove it in a uhaul back to Utah, and the second I took it out of the uhaul and drove up and down the street, I noticed the pulsing feeling. You are exactly right, it feels like warped rotors. I was hoping the brake recall would fix it... To no avail!
I did however notice it is much more pronounced stopping on the road (its street legal here) than stopping on the dirt. It was super frustrating to have "the best machine out there" feel so wrong when you stop... My xp4 1k had a much more powerful and better brake feel than my much more expensive "upgrade."
This was all under 150 miles on the machine. Yes there is an upside to this! As much as I wanted to take it in to a dealer I couldn't stand the downtime that always entails.
I was curious if the pads/rotors were just not broken in or something yet, and like I said frustrated, and so a couple months ago I went about 50 or 60 mph and aggressively stopped numerous times. I wanted to get the brakes good and hot. I did this quite a few times. To my surprise it helped... I now have 520 miles on the machine, and the brakes feel very nice and powerful. To be honest I haven't thought about the pulsation again for quite a while until I read this post!!!
I'm curious now though if it has truly gone away, or I just stopped worrying about it.
I'm going to take it for a spin in the morning and report back!

Ganks - thank you for taking the time to check and report back. At least now I know I do not have the only one that is experiencing this. I can duplicate on the street but is the same off-road, and maybe does not seem as bad because of all the bumps etc making the push back on the brake pedal compute in our brains as rough roads?
I live in AZ and is street legal and with off-roading right out my door I have done pretty extensive test runs and is consistent on or off-road. Funny you mention engine braking because in my yesterdays conversation with the service mngr at my “Chandler Ride Now” dealer he brought up engine braking since they are now doing a complete 180 and claiming they do not feel the pulsation after their multiple attempts to fix. Funny thing is they are still going to swap out the Master Cylinder since it is the last braking system component they have not replaced. Not sure why they are swapping out “IF” the pulsating is no longer present LOL,,, but ok wink wink.
I then said I am all about checking all avenues however engine braking doesn’t seem to be a cause of the brake pedal pushing back at you. Aggressive engine braking should just set you steadily up in your seat belt harness and not cause the car to “hop” and push back and forth against your braking foot,,,, but who knows??? So let’s say it is now pulsating engine braking 🙂 then I wonder what Polaris will so about that? No matter how your day set up it’s not safe because as so-and-so said it creates a hopping feel almost like your tires are out of round in between the pulsating feel on your breaking pedal and the car hopping it is not safe. I do a lot of trail riding in the back hills of Arizona and a lot of these are of DG (dirt/gravel) and the last thing you want is you are ripping around these dirt fire roads is your car hopping as you are on a downhill breaking hard at hopping feel remove the weight of the car from your tires,,, and when the weight of your car comes off of your tires you’re breaking grip that your tire relies on to stop is greatly compromised. This is my biggest complaint and what I am trying to get a dress at the dealer because this is not ideal in the least bit...
On a different note I spend some of my time at the Glamis Sandune‘s where this issue almost has no effect because between engine braking, and the soft sand I almost never touch my brake pedal.
It is the hard packed dirt and/or street where this is completely unacceptable, noticeable, and a complete safety issue.

Sorry for rambling but there’s just so much to my story and the failed attempts for repair and now seems like even my dealer is trying to minimize the problem.

Dannyphunt- thank you as well for taking the time. I think a lot of us purchase these vehicles assuming that the condition we receive them in is what would be considered normal and so our brain just kind of blocks out or minimizes these issues. The first few months and outings in my razor I felt it but I just kind of filed it in the back of my head and it wasn’t until the third or fourth trip I had it out I stopped and said this is it right. I then drove my friends 2018 XP turbo four seater and was then I knew my brake system had issues.
Again my thoughts on the engine braking are there it should not be causing a pull station in the brake pedal if I am applying steady pressure on the brakes and the engine braking is challenging the forward movement of the car I should simply be experiencing the car speeding and slowing as the engine challenges the psi I have applied through the brake pedal and into the master cylinder but should never push back in a pulsating motion.
I mean if we think about it the only thing that can cause the brake pedal to push back in a revolving motion on your foot would be the pistons in the brake calipers being pushed back into their borders ultimately pushing back the brake fluid through the line and up back to the master cylinder and ultimately ending up as a pulsating feel in the pedal.

I just don’t see how engine braking can cause the brake pedal to push back-and-forth on the brake pedal if I am applying steady pressure. In the hot rodding/pro tour/autocross world for which I frequent and have designed parts to combat piston “knock back”, I am all too familiar with braking systems in these type issues. Although I am open to any cause this particular feel would normally be contributed to work rotors or a misaligned brake caliper over the rotor... Since I have been told the Roeder’s have been replaced and checked in or not warped as well as I was told the caliper is correctly aligned over the Roeder one would have to think that is not the problem but I have yet to check this for myself and when I get it back in my hands I will be performing extensive tests and setting up dial indicators trying to figure out if we have something out of alignment causing the roto since I have been told the rotors have been replaced and checked and are not warped as well as I was told the caliper is correctly aligned over the rotor one would have to think that is not the problem but I have yet to check this for myself and when I get it back in my hands I will be performing extensive tests and setting up dial indicators trying to figure out if we have something out of alignment.
The braking systems on our razors or anything but of NASA design, quite simple so there is certainly going to be a cause for this if it is break related and I will find it if the dealer and/or Polaris cannot. That will be pretty pathetic though if neither of the two are capable.

I know there are lots of opinions on many different subjects on any given forum and referencing any given topic but this is one that hits close to home and because of the parts I have designed and experience I have with solving similar issues.

Just a quick update. I have received three more inquiries from other turbo S4 owners from a local Craigslist ad I placed informing others of their potential issues.
If you have text, emailed or spoke with me please jump on this thread and state your claim so we can compile a list of sort. It will be harder for local dealerships and/or Polaris to deny the issue as they are trying with me.

Please do post on this thread because it is threads like this that Polaris will eventually reference and may push them over the edge to handle the issue we supporters are experiencing.

I am thinking this thread could’ve done without these type sarcastic comments. I have been in similar situations and usually yield results. Comments such as these are usually viewed as counter productive and maybe why you have not had better luck in the past with your own issues. Just sayin’

I know I cannot control the feedback in this thread but I asked that unless you have firsthand knowledge and/or experience with the issue at hand please refrain from comment and or start your own thread. Thanks.

Ok I just went for a ride around town. The pulsing is still there. It is not as pronounced as it was 300 miles ago. And I did notice it went away to almost not there when I got the brakes good and hot. Don't know why that is, but with my machine it does seem to be the case that it gets better the hotter the brakes get!
Still....the pulsing isn't present at all in my buddies 18 turbo xp4. So something is amiss
