BMW X5 shudder problems

Filed Oct 26, 2026 · Transmission · CA

The vehicle experiences repeated jerking and shuddering from the driveline during low-speed cornering, acceleration from a stop, and under light-to-medium loads. No warning lights or Check Control messages appear. This matches the symptoms described in BMW Service Information Bulletin 27 02 20 regarding the xDrive transfer case on my vehicle. In November 2025, the authorized BMW dealer confirmed the concern, performed a transfer case oil change as the first diagnostic step required by the bulletin, and advised that if the problem returned the transfer case would need replacement. The oil change did not resolve the issue. The same symptoms have persisted. After being driven for about 8,000 miles, vehicle is currently back at the same dealer - BMW of Escondido - in order to address the issue. The manufacturer has directed the dealer to repeat the oil change yet again, although this oil is a lifetime fill and not subject to scheduled maintenance, and conduct an evaluation drive of approximately 200 miles before deciding whether to replace the transfer case.

Description of Safety Concern: I am writing to formally submit a vehicle safety complaint regarding the xDrive transfer case on my 2021 BMW X5. While driving, the vehicle exhibits noticeable hesitation, shuddering, and jerking during acceleration at lower speeds and when executing tight turns. This erratic power delivery creates a potential safety hazard, particularly when accelerating into traffic, merging onto highways, or pulling out from intersections, as the momentary loss of predictable drivetrain response increases the risk of a collision. Despite internal technical bulletins from the manufacturer (SI B27 02 20) acknowledging shuddering caused by transfer case clutch breakdown, no official safety recall has been issued. I request that the federal safety agency open an investigation into these xDrive transfer case failures to evaluate the safety risks posed by drivetrain hesitation and potential sudden power loss. Thank you for your attention to this safety issue.

The X5 transfer case has a defect that causes the vehicle to shudder when in reverse and at lower speeds. It can be felt sometimes at highway speeds, but is worse at low speeds. Our X5 has only 54,000 miles.

On [XXX] as I was driving on [XXX] in Fl and got in to some traffic I noticed the car was shuddering a bit when I braked and I could here metal against metal coming from the brakes. I called SIXT 800 number and spoke to a Gentleman at their call center in Asia. He asked me why I needed brakes . I was shocked at his response , needless to say. He told me he reported it and I needed to return the car in Miami at the airport . I spent the night in Jupiter as it was around 5 pm. The next day [XXX] I drove the car to the MIA Airport where it was exchanged for a new car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2022 BMW X5 is having the transfer case star to fail. Where the symptoms currently are at is the car has a shudder in certain situations. I can feel it when maneuvering at slow speeds and I can feel it at times at speed or when on a steep hill. I bought the extended warranty for the car and the maintenance package for the vehicle. I'm at 68k miles and the shudder started before that but I am still covered under extended warranty. I have had all maintenance done on the vehicle at the local BMW dealership including all tire needs and have always replaced tires as necessary and number of tires at a time they suggest. When I took it in as the vehicle is reporting needing brakes 2 weeks ago, I mentioned the shudder and asked about tire tread on the 2 front tires. They came back with that the tires were fine in spec with the back 2 but that shudder is the transfer case. The dealer also then mentioned a couple things: - They now recommend changing the fluid in the transfer case by 60k miles due to amount of failures they are seeing (my X5 was in the dealership multiple times before an after 60k and it was never recommended). - that since it is not in the recommended maintenance for the xdrive4.0i that the car would not alert to have it changed and therefore BMW would not cover changing the fluid under the UltimateCare (service maintenance plan they sold me). That the transfer case was meant to be a for life fluid. - I asked what happens next if the fluid is not changed, that it will continue to degrade and once it fully gives out the vehicle will become inoperable - I asked does the fluid change save the transfercase and they said it seems to help many vehicles and the shudder disappears but for some it does not. - I then asked would the BMW Extended Warranty purchased cover it if it fully failed or the fluid change did not solve the shudder and I was told maybe fully, partially or not at all. Ext Warranty brochure says it is covered at platinum level I hav

I own a 2022 BMW X5 xDrive45e that has developed a drivetrain shudder during slow-speed, tight turns while lightly accelerating, such as when maneuvering in parking lots or making U-turns. The vibration is consistently reproducible under these conditions and is felt through the vehicle during the turn. The vehicle otherwise drives normally at higher speeds. After researching the issue, I found that many other owners have reported substantially similar symptoms involving the transfer case on BMW xDrive vehicles. My independent BMW repair shop has recommended a transfer case fluid service as the first corrective action based on the known nature of this problem. I am having that service performed and will retain all repair documentation. I am submitting this complaint because this appears to be a recurring issue affecting multiple vehicles. If the condition worsens, it could lead to drivetrain binding during low-speed maneuvers and may affect safe vehicle operation. I request that the federal safety agency investigate whether this is a broader defect requiring manufacturer action. I will update this complaint if the repair does not resolve the condition or if additional diagnosis identifies an internal transfer case failure.

I took my 2022 BMW X5 xDrive 45e for concerns of shuddering at low speeds and tight turns under warranty. No warning messages on dashboard. I asked specifically what was causing the shuddering. BMW of Raleigh would not respond. But they found that the Transfer Case was affected so they flushed the oil and put an oil mixture replacement in. According to the most recent BMW service bulletin, the technician is only to put in DTF oil. The technician not only put in DTF oil but also an over-the-counter non-approved chemical additive. Reading the service bulletin, the Transfer Case is supposed to have a lifetime warranty. We were charged over $500 for this "oil change", but it was under warranty. Transfer Case failures can result in accidents on highways and other roadways and complete mechanical failure of vehicle.. The oil change did not fix the Transfer Case issue but extended out the vehicle so that it now falls out of warranty. A TC replacement will cost $10,000 or more out of pocket. TC issues is a known BMW issue since 2018. Lawsuit has begun w/thousands of plaintiffs all over USA w/ 2019-2025 BMWs because they refuse to acknowledge that they are at fault even though they continue to put out bulletins for this exact issue. BMW has made sure that Transfer Case is not on any warranty they offer.

I am writing regarding my BMW X5 xDrive40i, model year 2019. For this G05 model coded cars, repeated transfer case failures have been reported due to a known issue: on the factory they put a wrong oil in it and then published a Technical Bulletin about it as if they are not the ones responsible for that. The problem is, due to that mistake, transfer cases of cars manufactured between 2018-2020 becomes dead in time. Cars shudders, jerking at low speeds, cannot deliver the power to the ground effectively due to intermittent and very disturbing, powerful shudders. This creates a huge safety concern cause: 1) if you are on an intersection the car might not join safely to the traffic in a perceived timing due to the shudders, intermittent power delivery. 2) If you are on a driveway and moving to the street the car might not move to the street for the perceived timing or once moved cannot move safely to join the traffic. 3) If there is a failure on the transfer case and if there is a sudden stop is needed. On the road with no shoulder access or if this is a bridge where there is no shoulder, it creates a huge risk to safely move the vehicle. An unavoidable sudden stop can create a huge accident risk for everybody. This is a very known and very common problem for BMW cars equipped with B58TU engine especially years 2018-2020. BMW is also definitely aware of that and this safety concern but instead of fixing it they moved away their responsibility as if they are not the ones made the mistake. But, when contacted with BMW NA, they refused to help.
