Exclamation 3rd brake replacement on 2019 X5, help!

I have a 2019 G05 X5 40i with M sport package and 22 inch wheels. Bought the vehicle a year ago from the dealer as a demo with 12 000km on. At delivery I noticed a shudder when braking, I immediately returned to the dealer and it was found to be warped rotors and the dealer replaced only the rear rotors which solved the problem. Another 20 000km later, severe shudder returned as winter started setting in, winters aren’t harsh and it is mostly lots of rain and temperatures just below or above freezing. I was told it was the rear rotors again and had to replace them and the pads at $1600. BMW said it is my driving habits. Got the vehicle back, and the shudder was better but still there upon braking. Vehicle went back, another $1800 later for front rotors and pads. I’ve done less than a 1000km on the vehicle and within a week after replacing all the brakes for the 3rd time, the shudder is back. All 4 rotors have heat damage and BMW again tries to blame this on my driving style. I do highway driving, 100km to and from work with minimal to no traffic at around 120km/h. No crazy braking or cornering at all, my winter tires are still brand new. Tires and balancing and all of that has been checked, only shuddering when braking both on summer or winter tires/rims. I feel helpless, BMW Canada refuses to accept something is wrong with my vehicle and hides behind the fact that brakes aren’t covered under warranty and that my driving style is the cause and I should pay for brake replacement every other month it seems. I drive my partner’s 428 every other week on the same route at the same speed, never had issues with the brakes. How can it be reasonable that this type of vehicle with less than 40 000km and with M Sport brakes have warping rotors after less than a week’s driving? What else might be the cause? This vehicle has turned into the worst driving experience and no solution or cause can be found. Someone please help or offer advice

this is very strange. If all 4 Rotors has heat damage than they should look at the brakes. Maybe the brake cylinder doesn't retract as they should. Normally you brake with your right foot but maybe your left foot rest on the brake pedal during driving?

Assuming description is accurate and complete:

- no, this is not even slightly normal at all

- if you believe all civilized avenues have been exhausted, it may be time for lawyers for a breach of warranty claim against BMW Canada; but there may be more "subtle persuasion" to try first, persistently and firmly but politely insisting on escalation; as soon as you mention legal action to BMW, there is no going back, it's going to have to be legal action

- an issue as well is if this car eats rotors at such an alarming rate, it implies a severe defect in the braking system somewhere and that may not be safe; a safety issue on a car under manufacturer warranty being refused may allow appeal to transportation safety departments, but beyond that idea, I have nothing to support it from any personal experience

The biggest reason for rotors warping is failing to properly torque the wheels during installation. Excessive heat could be a problem, but that's harder to generate unless you live on top of a mountain and ride the brakes all the way down or play on the track all of the time.

Your experience is very different from mine. I just replaced my rear pads and rotors at 33,000 miles and will need to replace my front brakes soon. (I always use the Auto Hold function, so no surprise my rears wore out first.). My 2019 has the standard (not M Sport) brakes, but I can’t imagine that would make much of a difference.

He's had, what, 3 rotor changes now? And the mechanics over/mis-torqued every time, including from factory, on every wheel? Doesn't seem likely, although incompetence really knows no bounds.

Is taking it to a different dealership a viable option?

Hello, I have the same problem with my X5 30d 2019 with M sport package. The rotors get warped after about 7-8k km. They were replaced under warranty once, now they are going to do that again without any clue what is causing the problem...
The most interesting is that I'm not an aggressive driver and I never hard brake, because I'm riding with my children onboard.

I have exactly the same issue with my 2020 MSport. The dealership resurfaced the brakes at around 8k miles and now at 14k, the brakes are warped again. I only have my car worked on at the dealership so I’m not sure what’s the solution. It’s driving me crazy every time the car comes to a stop.

Anyone have suggestions? Are there other brake options (different rotors and/or pads that would solve the issue?) I really like the X5 and while it’s a lease, I may end up keeping it at the end.

Help!

Just had rear discs( rotors) replaced under warranty , 34k in, had noticed the 'in cabin judder' probably 6-7 k ago , quite subtle. and only really noticeable on very smooth surface. Won a watch really as the pads had only maybe 2-3 k left on them, Im not a particularly aggressive driver either .

Reviving this thread - what was the damn outcome?

Taking mine in tomorrow as I am noticing some suuuuper mild pulsating - but doesn't make sense as brakes/rotors/sensors, everything - were done less than 5,000kms ago (front and back) - M Sport.

Jfb8407 you kicked this off, and given I am in Canada - what was the cause and solution? Would love to hear from you.

simeon what was the outcome for you? Curious and this is good info to share.

rtadams1 any info you can add?

Doubt you will get a response from Jfb8407. According to the profile stats, that was their only post and hasn't been on the forum since then.

Update - two separate dealerships confirm the mild pulsating right at the end of the brake (shortly before stopping) exists.

One dealership states this is normal for m sport brakes lol

Another says it may be due to the wheels/tires - 20’s with all terrain tires (purchased this way). While that may influence things, it doesn’t explain the noticeable change in brake feel that I picked up on…

Both dealerships state the brakes/pads/rotors look brand new (that’s because they basically are) - no signs of rotors warping or uneven brake pad wear.

Could a pothole have done this?

Wheel/hub bearing?

Other ideas?

It is Pissing me off lol

Yeah, that situation has all the earmarks of legal action immediately after the post (the OP was pretty detailed, which reliably rules out trolling).

For all those that have this issue, based on these reports it seems there is an intermittent factory brakes defect issue and while it seems real, it also seems rare enough to have generated neither more forums discussion nor recalls (or likely even BMW acknowledgement) — difficult situation that can really only be resolved with outstanding dealer relationships or legal actions.

Just for anecdotal data, here is what my 4 year-old G05 X5 40i brakes experience is:
  • I can be an agressive driver, but tend to now leave that to M3s and track, rather than an SUV; so let’s call me mildly spirited with the X5
  • rear brake pads replaced first at 3 years and around 40K km; including rotors
  • front brake pads replaced just now at 4 years and around 52K km; including rotors
  • it is standard experience now with modern BMWs for the rear brake pads to go first; that’s due to the intentional (and effective) anti-nose-dive bias
  • it is also now standard for higher performing modern all-disc brake rotors to wear at about the same rate as the pads, particularly on heavier cars; I am not entirely clear whether that’s due to revenue-boosting planned obsolescence or due to tradeoff for increased braking performance; softer rotor materials that make rotors (more) sacrificial than past rotor designs would help both and I suspect it is actually both; much more expensive maintenance, but the brakes are fantastic (almost track quality on an SUV)

And it is definitely not normal on either M-Sport brakes nor on any configuration of wheel or tire (unless, of course, wheels are damaged or not balanced ... but in that case the shudder would occur at certain speeds, including all speeds, but regardless braking action).

gx5_027, what’s the mileage on your car? The previous discussions were all about almost brand new cars, but if we’re now talking about aging cars, new failure modes are possible.

Outcome: ever so slightly bent wheel (pothole). Sharing so others can benefit.

Last year they did third in a row rotors and pads replacement (at 29k Km) after a full inspection of the brake system with no other problems found…
Replaced brake rotors were like new ones with almost no wear but warped.

I had this issue on our f16 x6 , which was traded in against the current x5 .

Traded in with only 26.500 miles and was on its 3rd front rotor , from factory the first ones went at 12.000ish miles ( fronts ) and were replaced in pairs ( was told this by the dealer ) .

Second time it was near side front that warped again and only that rotor was replaced as had only done less than 5000 miles .

The reason they gave me was one of the 21” diamond cut wheels had been refurbished unknown to me ( bought as a pre register 6 week old vehicle with only 58 miles ) and this was why heat was not dissipating away from the disc causing it to warp .
Fought with them all the way but was out of pocket on both replacement rotors .

So my guess is someone in the dealership has had it repaired before I’ve received it , either transporting damage or test drive
