Your hypothetical statement above is accurate from physics perspective and I agree with your assessment, however my counter argument against BMW’s stance to blame spacers would be that there are many OEM wheel options with high enough offset which push out the wheels similarly. From physics perspective both scenarios should have same effect on TC. No?

Hey All...long time Bimmer guy back to 2006 and DONE with the brand after my 7th and final Bimmer, my 2020 X5 because of transfer case handling by dealer in Warwick, RI and bmwusa. Although discovered while still under warranty and needed replacement they charged me $700 for fluid change which lasted just long enough to put me out of warranty for the real repair. Then after much unnecessary hassle they agreed to charge me 50% of $9400 to replace TC, which is what likely covers their cost! Sad that my love of the brand ended this way. Bmwusa, playing games with your customers isn't smart. BTW, loving my new Tesla! So, thanks.

Those that have had transfer case issues what size tires did your vehicle come with?

I’m wondering if the non-square setups are a bit more prone to this than those with square setup. (Square meaning Identical tires sizes front and back)"

OEM 275/35 22" and 315/30 22"

Maybe. BMW claims it's when the tire diameter difference between front and rear exceeds a certain threshold for a period of time. One would have to replace tires every 6 months to maintain that.

Mine had 21 inch square with continental tires that came with the vehicle.

Does anyone have experience to know if BMW will do the TC change out of warranty if you did the fluid change as "step one"?

Did that about a year ago, about 3 months before warranty lapsed. Now a year (and only about 2K miles) later, warranty is lapsed and shudder is back. (My older mother drives the car, so took a while with her low milage driving for it to return)

I had the identical shudder issue at 44K miles. The dealer required me to replace ALL 4 tires at $2200 before they would even test the vehicle. It seems that if the wheels are out of tolerance the system has a difficult time calibrating causing it to shudder.... After the transfer case, i still have a small shudder on some right hand turns and slow speeds. It is difficult to replicate. I am going to take it back to the dealer one more time in hope they can resolve. Chat GPT recomended a VTG adaption reset and CDC calibration. any thoughts?

Does it say anywhere in the owners manual that tread wear differences between tires must be less than 2/32" to avoid mechanical damage to their crap designed transfer case (must include "crap designed" to be legally binding - lol)? Even if it did, this would be something not reasonably known to a consumer prior to purchasing the vehicle. Since it's not "normal" practice to require such minute differences between tires (not even for safety reasons), BMW is treading into dangerous territory should a lawyer be engaged to enforce the warranty. I suspect the lawyer would include claims of fraud in addition to the breach of warranty agreement.

I suggest you go back to the stealership and ask them to show you where you were presented with documentation and where you consented to maintain tires with less than 2/32" of tread difference during the life of the vehicle and/or it's manufacturers new car warranty.

In other words, dumbest crap I ever heard. BMW is asking for a class action which will likely result in a settlement that will cost them way more in the long run. Honestly what they should be doing now (or should have done years ago) is to add a scheduled fluid change to the maintenance schedule for xdrive models. This preventative fluid change would likely save them $ and reputation damage. But seems they prefer to learn the hard way. Tough to fix corporate stupidity.

Hello ALL, Just wanted to share my experience on this TC shuttering on my 2022 X5M50i with 41,000 miles. I think my shuttering started around 40k? Not too sure at first i thought one of my front suspension bushings were giving out. SO glad I did some research and found most have this similar issue! I took it in for service and the dealer recognized this was a known issue. They preformed the SIB 270220 (REV4) 2025 ! I guess they’re using a NEW fluid 83-22-5-A4F-016. I will attach the updated SIB if not already posted on this thread. The one I read from this thread was a 2020. Dealer advised the fluid needs a break in period of 125miles. I haven’t gotten there yet but will update once I get there.

Just hit 20k and got my service done for my 25 G05 m60. Thought it was interesting that the transfer case fluid change was included. I asked my SA about the transfer case issues and he acted like he didn’t know about them.

Howdy everyone, new BMW owner here

CPO 2023 X5 45e with approx. 18.5k miles and, maybe I’m being paranoid here but I could swear that I feel a shudder sometimes during low speed turns. It’s not all the time, only occasionally… Literally JUST bought the car this month and haven’t even put 100mi on it yet… I think the next time I feel it I’ll try and take note of the conditions (speed, steering angle, slope, etc.) and then see if I can replicate it at will…

If anyone is in central NC area, which BMW dealer seems to be best at dealing with the transfer case issue?

I may need to be added to the long list of unfortunate X5 -owners with transfer case failures. I have a 2021 X5 M50 with 39k miles which is out of warranty. After a 250 mile drive the other day, I was backing out of a parking garage spot and heard a thud when turning the wheel. Does this sound familiar to anyone? The vehicle drive fine for the return trip and parked it in my driveway and will likley not use it again.

I also had a front diff failure a few months ago at 36k miles and it was replaced by the dealer for $11k. After that happened and reading about all of the other costly issues with my model, I made the decision to part ways with BMW since it became clear it would become a money pit when I could potentially be looking at another $30k+ in major component failures like the plastic oil pump etc.. I have not replaced the fluid and prefer not to throw good money after bad so I passed on another bill since the vehicle is going away.

I ordered a 2026 Cayenne GTS in December which is at the port in Germany and is delayed for a few weeks. Luckily I have another car to use so I can get this one sold or traded in.

Well the depreciation you'll lose on your Cayenne within the first year will be far greater than what it would cost to maintain the X5. 30k is an exaggeration though

Some of us get lucky some of us don't unfortunately.
