I love the part where they told you 3 separate times to come back instead of of just saying “take all this stuff off and get back to stock”. Clowns

Personally I would’ve put the car back to completely stock form … seems like over the years BMW has become way more strict with the work they warranty out. But him not being transparent about what you’d be bringing the car back for is insane and terrible professionalism.

Shop foreman was probably giving you hints to demod everything, before they submit a puma case. Additionally, shop foreman will likely face disciplinary action for giving you such a wide berth on demodding before warranty claims. Everybody knows that the mods are not the cause of the problem. However, once BMW NA gets a hold of any evidence they will find every excuse for voiding warranty claims. It is a bummer.

Hi! I have a tune/race shop, ive seen things like this with porsche amg and M cars with drilled rotors. Usually drilled rotors will cause vibrations, try swapping the rotors over to Girodisc, and lightly sand your brake pads before putting them on. Your oem pads look crystallized though, maybe follow a better bedding in procedure next time!

I’m surprised BMW allowed you to take mods off and then come back in to inspect, usually they tell you “sorry mate you have voided your warranty” and that would be the end of it 😆

BMW knows that they need to do better. If this becomes a larger thing involving more people, like you mentioned, they'll likely be much more compliant in the future. Keep your chin up. I've been watching you make lemonade out of lemons for quite a while now. These are small potatoes. Keep on creating. You are supported.

I did 33k miles on my first G80 and 12k on my current one without a single issue ever. For the most part, these new M's are SOLID.

Wow yeah this does suck. This, as you’ve found out though, is why you don’t go messing with cars still under warranty. My AMG unfortunately needed a couple of things fixed/flat out replaced and I’ve paid zero dollars for over $6k of work in all. I wish you better and that your channel continues to do well and grow.

Sounds like a class action lawsuit until it is recalled

I have 4000 miles (3000 of them are hard miles on back roads with hard breaking) on my M2 and after watching this video ran out to garage to check the rotors. Mine have zero waves and look brand new. I do not have an HEA spec and have a CA car which did not sit at the port. I think your conclusions are probably correct. The most interesting thing you discovered are that the break pads on your car are different then the M3/M4 pads. I wonder if that is the case on all the M2's or just the HEA cars?

Just to be clear, BMW repair videos and video content on common problems on BMWs IS the reason why I bought one. Seems counter productive in a sense, but the reality is channels like this, made me buy one. Maybe BMW should thank you

This just goes to show Cristian that you are the bigger person and know how to troubleshoot better than the "professionals." Kudos brother. 👊😎

You’re a bloody legend, respect to you, they should have at least acknowledged you for giving them solutions to this soon to be issue, these people are evil, acting up instead of owning up!!!

This is not uncommon with the F87 M2 Comp, F10 M5, or other BMWs with 6 pot calipers etc. It's been happening for years. It seems to be caused by pad material transfer to the rotors that becomes semi-permanent. Some people claim to have fixed it by replacing the pads with more aggressive track pads that scrub the rotor of the hardened deposits. Almost no one has this problem if you replace the pads. Not sure if you need new rotors or not honestly. I don't have any proof but my theory is that this pad material is not suitable for high performance cars. If you notice, somewhere a few years ago the brake dust on all Euro cars became brown instead of the old grey/black looking dust. The pad material is now a low copper Euro 6 compliant material which is even dustier. It seems like it just has the tendency to do this under some conditions. I would just replace the OEM pads and not look back.

Damn I was thinking of getting a m2 glad I watched this video. Thanks man! hopefully you don’t have any other issues going forward

You earned a subscribe from me for your authentic honesty with your videos. I am looking to get into a m135i and customize it. Will be using your vids for ideas and support and will be buying from your site! Keep being real with us BMW lovers!

Perhaps you could get those discs skimmed? I don't know if you can do that to drilled rotors?

Sucks bmw isn’t helping but you can’t blame them. As soon as you touch the car and it’s no longer all oem, they wanna shift blame. I wouldn’t be surprised if this becomes a recall however

I got warranty work done last month at first they told me I wasn’t covered even tho it’s listed on the covered parts then they told me half was covered and the bill the 3 times what is was initially . Had to pay for half of the work, after that my car was still experiencing the issues they insisted that it was fixed but I had a video but after it sat in the shop for another few hours they recommended a engine bay clean for 600 and they car didn’t need any work. then they tell me my dif is going bad they tell it’s covered but not until it breaks but they can do it now for 7k 😂. Then they send me a email saying they want to purchase my car for 1/2 it’s value but say sent a report saying it’s in excellent condition makes no sense. I remember when warranty work was done no questions asked. Thanks for the great content.

I wonder if some major heat in the stock brakes would fix the vibration. Track day?

The wear in the rotors is normal, for the kind of spirited driving you do. Unfortunately the pads have been an issue with the new m cars and m sport brakes

It's honestly disheartening to see a brand like BMW not recognize the passion and dedication of car enthusiasts. They should be partnering with people like Cristian, who bring innovation and insight, rather than putting up barriers. Let's remember that it's the enthusiasts who truly keep the brand alive. BMW, listen to your community! 👏🚗💨

Thanks for the heads up! I’ve got 2024 M2 and I’m at 2320 KM. I’m scheduled for first service this coming Monday and so far no issues with my breaks except the squeaking sound every time I break at low speeds. Might be dust or chips stuck between the pads and the rosters but I’m definitely going to ask them to check the breaks! I live in Germany and my car is US spec

We had one at our dealer that was doing the same thing. Warranty admin unloaded the parts shotgun and gave it a new steering rack, brake booster, and other bs. In the end, resurfacing the rotors and flat sanding the pads was the only thing that fixed it. Hope this helps anyone in the future!

Warrantys and mods mix like water and oil. Im sorry about that man, you even proved that it wasn't related but they are being difficult. When I worked as a finance manager and Chrysler and sold extended warrantys I would make it very clear to my customers to keep the car completely stock and do all the factory required services to keep their warranty in good standing. I saved a lot of people from making that mistake. But you are a creator whos business is car modding content so this is just a business expense for you. Keep up the great work, you're helping people out.

I would definitely replace the rotors as well just for a piece of mind

Can you skim the surface of the brake disks/rotors to make the surface smooth again to lower the risk of the issue coming back in the future ?

did you upgrade your motor mounts? every time i upgrade motor mounts then your car vibrates inside massively.

Sometimes it depends on the dealer when it comes to turning the other way on warranty fixes with mods in place. Definitely depends on the mods and the issue. Sorry for ya bud. Good reminder to folks to remove all mods before going in for warranty work if there’s any question.

Call a lawyer.

from a BMW tech, The scoring on the rotors is normal. its due to the metals in the brake pads. some parts of the pads are harder thus causing the grooves. BMW's are notorious for warping rotors. they can warp 2 ways, 1 heat, which since those rotors are drilled should not be an issue and the other is pads hanging up causing uneven wear/high low spots on the rotor which will also give you the feeling of a pulsating brake pedal. you can't resurface those drilled rotors from what I know. find a good replacement like Hawk rotors and pads. you may still have noise but no vibration. also make sure you clean all contact points. only use silicone grease on the edges of the backing plate and not on the back of the pad where it touches the pistons of the caliper. also for reference next time you go to the dealer take off all aftermarket things first so this doesn't happen again. I feel like you learned that(the hard way) if you have any questions feel free to ask. beautiful car you have there.

I wonder if the calipers have anything to do with that? Like sticking or something.

I've stopped modding my F10 with my interest moved to my STI but I always look out for your updates to save myself and my pocket 🙏🏾🙏🏾

I would definitely resurface those rotors prior to installing the new pads. They will work great to begin with but over time your rotors will eat up the pads. Im glad it wasnt an ABS issue honestly. Pads and rotors are easy

That car is one sick ride. Your a BMW badass you’ll get it figured out.

Since those rotors are really thick and new you could get them turned no? Just to smooth them out.

Can’t believe they are being so dirty about such simple mods! There is an entire industry behind these simple mods for making the car better for track days. Plus I thought some of this stuff was addressed with the Magnuson Moss Act in the 70’s. I understand that they want to protect their interest in factory parts replacement but at the same time, what are they saying about all their value added, modification, manufacturer partners out there?

This turns me off buying a bmw. You are spending $75k+ on a bmw it shouldn't have these issues and if they do bmw needs to address and fix it.

I'm sorry for your issues man. My local dealer in the NW has been amazing. Sounds to me like that specific dealer's maintenance department doesn't want to do work and comes up with every excuse to achieve this goal. My local dealer even installed third party carbon fiber air inlets on my G80 M3 that I owned for 6 months!!

I managed to get my hands on a 2020 M2 CS with the the dual clutch automatic and I have no plans to modify it, certainly not while it still has warranty left. When the warranty expires, I might do a few Dinan mods, but it’s already crazy fast. I love driving it and am slowly exploring its capabilities. I had to fly out of state to get it and had already missed out on 3 others that slipped between my fingers before I could get a down payment in place. It had just over 4K miles on it and as far as I could tell, it was the last low miles, stock CS left in the US.

resurface the rotors, you will have plenty of material to stay in specs for the rotor. This is so easy to fix. Resurface the rotors and swap new pads.

You'll see a TSP / recall come out in a few months about it. Id like to know what the dealership was so we can know who to avoid. Also, I would recommend taking this up with BMW NA customer service.

Have you tried measuring the rotor runout on the vehicle with a dial indicator? This should give you much more insight on the issue.

Can you tell me what rims are those? And where you got’em? Thanks

I would bring it to another dealer ,There is a clause in warranty ex , If you change your wipers to another brand and you have a transmission problem they can’t deny a claim because you don’t have stock wiper blades , you can easily prove what the problem is at this point

FIRST problem .. u bought a g m2 instead of a g80 m3 Lol.. perfect wheel combo tho ;)

That front face looks stunning 😍 BMW snaking customers like that is not good customer service they will end up doing a recall

The Magnuson-Moss Warranty Act requires the manufacturer to prove that your modifications have affected the car with respect to what you are seeking warranty for. They are operating against the law if they are throwing out your modifications as affecting the issue if they are clearly not involved. This is a good case to send BMW a letter seeking clarification and requiring their response (serving them).

as much as i liked the g82 m3's i decided not to purchase them anymore because their customer service isnt really there anymore when it comes to their cars. i had the same issue with the f82 m4 and they never wanted to fix the brakes and it still seems to be an issue with their current gen m cars. i just went ahead and got myself a type r. maybe if they bring back their old customer service id reconsider another new M car

Yo , as a dealer tech I’m just say they just didn’t want to do WARRANTY work, service manager figured out a way to not warranty your brakes and you get stuck with the option of pony up the money and replace them or take the car out the shop and I say replace them yourself with a upgrade and move on with life

I was gonna buy an M2 and I’m so glad that I went with the fl5 type r 5k miles 0 problems

Why wouldnt you replace the pads first thing? What else could it be?

in general, all drilled-through rotors are problematic because they tend to shave the pads more quickly, unevenly and after few thousand miles of hard use, they start cracking themselves starting from those holes so it could be also the reason it creates vibrations under soft braking..

Well I’d never buy a BMW after seeing this lol. What a nightmare. This needs class action lawsuit. Keep fighting.

The wavey wear on the rotors is a characteristic of drilled rotors. Drilled rotors wear unevenly due to the holes in the rotor they always wear a wavey effect into the rotor. It happens to most drilled rotors and is not specific to BMW. So you know, the weights on the M3 pads are most likely for vibration control. Another method used to cut vibration is to chamfur the edges of the pad so the edges of the pad are not 90 degrees to the rotor.

Have you had the rotors machined since? If you get it done before they heatspot too badly they should be salvageable.

The M cars are insanely expensive now. They should be fucking perfect! Unreal and disappointing. 😮

Rear and front lip produces too much downforce, causing warping to the rotors. Also that strut brace is a ticking time bomb for the engine 😂

Sounds like possible warped rotors , could be from it sitting , condensation and what not. Had a brand new 2023 expedition do the same thing with 50 miles on it

If your car has the optional M compound pads its probably the pads. Most track / racing pads are very aggressive and vibrate / squeak like that when coming to a stop as they are meant for high speeds and temperatures. Im not sure what pad compound BMW uses but I have experienced this very issue with may cars running racing pads in the past.

Since BMW is not going to do anything, put back all the mods 😉. As you now know you are not the only one with the problem, let’s also see what happens with the other owners and their complaints.

I used to work for bmw I saw this all the time the reason why they don’t want to service it is because warranty will kick back the claim and the technician won’t get payed … warranty what they’ll do is cut the rotors and replace the pads .. those rotors were probably warped due to going fast and then heating up the rotors and running into water getting the rotors wet … that’s how u warp rotors and u can even see also on the rotor a little .. don’t be surprised if it happens again in a couple months

Thats how they are. Even when the car is completely stock they have issue honoring warranty so. On my experience I dont care about warranties anymore. If I can afford the mod and the issues later I go ahead, if not I wait but I know I’m on my own at all times.

a few thoughts. Take the rotors off, clean and anti seize the mating surface on the hubs and rotor. Conduct a brake pad bed-in procedure, and or have the rotors turned? I know that turning drilled rotors is a no no AND why should you have to go through this but just some thoughts. the lack of weight and vent channel on the brake pad could be due to Caliper design but I am unfamiliar with the caliper difference on the M3 vs M2. Love the Videos!

Tbh bro you should have never modified it while it was still in warranty, always gotta be careful with stuff like this, maybe its US market only, I’ve never heard of this issue - another thing is you should have removed all mods before you took it the first time, dealerships do everything they can not to do sh*t for customers lol.

They need to provide evidence that the mod caused your vehicle to vibrate, they can't just cancel your warranty, that guy at the dealer is indeed a snake, he suppose to advise what he was doing with your vehicle, you thought it was for repairs but he was busy documenting the mods.

It’s not rust or rotor problem. It’s the compound of brake pad material. I had the same problem with my Audi RS4. The oem brake pads are junk with you have to run upgraded pads if you do any enthusiastic driving. Thanks for the video.

Curious about any common factors of the cars sharing the symptoms. Same port, calipers, build months, factory, anything?

It's a shame you can't take the car back and tell them to keep it. Some times it doesn't pay to mod a knew car, unless your going to race it and change everything anyways.:((

Dude. If you want your car warranty on a new car, DONT. MODIFY. YOUR. CAR! You clearly knew the consequences of your actions, and you took the risk. The reason they are so strict about warranty work is because people take advantage of them all the time and have ruined it for everyone. I know how mad you must be, because I did the same thing with another car I had and they eventually declined all warranty repairs even though they were unrelated. So yeah, don't blame BMW, but put the blame where it belongs - on the assholes who mod their car, then return it to stock to get warranty work done! THEY are the reason for this nonsense. BMW is a business, and is just doing this to avoid getting taken advantage of.

Its one sweet ride!

Yup this seems about right for the Ultimate BMW Dealer Experience

Mods aside, they tricked you into wasting your time/gas to bring the car in under false pretenses. They had no intention of doing anything but documenting your car and voiding your warranty. Did you risk voiding the warranty modding the car? yes. Should you be pissed that they misled you purposely in order to snitch to BMW? absolutely yes.

Fields BMW staying petty. Trash A.F. dealer. To the Central FL people, take the 1 hour drive and go to Ocala. Fields group is embarrassingly awful.

I had that experience on my f30 and it was the horrible cheap break pads which not only vibrated but swivveled my steering wheel when braking.

Good stuff dude

Would they still make you remove cosmetic mods? like a lip or side skirts?

So, why haven't you turned the rotors? Can they not be turned ?

Can confirm with 2.5k miles no brake problem, still stock while in warranty.

Thanks, man. Hopefully, they will fix this issue before I put a deposit for a M2. I am sorry it happened to you! As a soon to be first-time BMW owner, this does not look good.

Just curious, dont you need to “bed” brembos when you first get them or they’ll have a coating?

I commented on the last vid.. The issues is the pads do not move smoothly in the caliper which causes the abs to kick on.. that's the issue, I have experienced the exact same thing

I just ordered one, I hope this issue is not going to be an issue going forward.

The roters may be too hard? Are they after market?

I would recommend resurfacing the rotors if it becomes a issue again, it would be the cheaper route. But wow that BMW employee did some bs!

Diff platform…but my 2018 Kia stinger GT had the brembo kit from factory too and we found out state side cars got a different type of pads and material. I then ordered the overseas stock spec pads and it fixed problem. Also Kia replaced rotors for free because damaged them. If there are difference parts number for overseas spec pads. If so…May fix problem. Just wanted to share this in case it’s helpful T Williams

I have a 2014 335i that came from factory with the M-performance(not the M-sport) kit with the yellow gold calipers. It’s the highest brake trim from factory you could get. When I replaced the brake pads and rotors at 40,000 miles the rotors were MANGLED! There was a TERRIBLE SCREECHING sound every time I came to a stop, as well as some vibration. It seems this may be a repeat.

Abs could be the cause of the rotors going bad. glad the new pads relieved the issue

this deserves a lot more attention. It's BS they declined you for their F ups...

You would have to test the car with eom pads and modded suspension but also test oem pads and stock suspension

Did this vibration happen when it was BONE stock???

Do you use fuel injector cleaner. Its good to put in the gas tank ever so often use liquid moly. Hope that helps 👍👍👍

I was thinking of buying an x3m, but seeing how BMW treats you and very very very simple and straightforward modifications. Looks like I will not be buying a BMW now.

The entire problem was that your original pads were glazed. You could have fixed this easily by yourself if you just sanded the pads down to remove the glaze from the pads. I've had the same issue and it was an easy fix.

I can see both parties points of view about 50/50 for once. Nice car at the end of the day, at least it's not some E60 type deal.

This sounds like a problem with either suspension or engine mounts. Did you upgrade any of these to stiffer aftermarket components?

It's interesting that a lot of people talk about the importance of "bedding in" new pads, but there's nothing in the manual about it. I bought a 2024 M2 a few weeks a go and did a couple of hard high speed stops on my way home. Now I'm struggling with self control to avoid full throttle and redline. 😉1200 miles seems like overkill for break in....

I would’ve recommended to just flip the pads from the left to right and right to left and see what that does. Was a confirmed fixed on a g80 m3 we encountered the issue with.

Bro I have a 23 M3.. I can feel your frustration. Dealing with BMW dealerships feel like you are going to a hospital always prepared for Bad News. I had the same issue on my 23 M3, at 2k miles. Tech blamed me for using tire spray or rotors damaged by ceramic coating. I took the car to another dealership in the area they kept the car for full week and couldn't diagnose the issue, trying to blame my aftermarket mods. Eventually I got the GM involved and he literally got my pads and rotors changed in 1 day at no cost. He is a great guy! And I have literally no words to thank him. However, after another 1k miles that issue is back and I think it's the brake pads again, can't be rotors. I am just going to break all hell loose on pads first to see if I am able to bed them otherwise I will take it back to dealership.

There's still time to save the rotors if you wanna turn them down clean. I mean if it's an option cause once those pads wear good we all know your gonna experience the vibration again.
