2022 BMW X5

Description of the Complaint: I own a 2022 BMW X5 (VIN: [XXX], current mileage: approximately 39,500 miles as of 08/24/2026) equipped with the B58TU engine, which uses a plastic oil pump (part number 11418646454) rather than a metal one. I have not yet experienced an actual failure, but I am reporting this as a precautionary safety concern based on the following: 1. On BMW's official parts reference site (RealOEM.com), the oil pump for my specific vehicle is flagged with an "Attention! Observe PuMA measure 65494813" notice, indicating BMW's own internal system has identified a known issue requiring special observation for this part. 2. I have learned that BMW Korea has acknowledged this plastic oil pump issue following a government investigation, and has committed to a full free repair program for affected vehicles in Korea. 3. I am aware of multiple reports and complaints from other B58TU engine owners in the United States regarding this same plastic oil pump issue. 4. Given that the oil pump is a critical component for engine lubrication, a failure of this part while driving — particularly during highway or long-distance travel — could pose a serious safety risk, including sudden loss of engine oil pressure and potential engine seizure at speed. I am filing this report to bring this issue to NHTSA's attention before an actual failure occurs, and to request that this be considered as part of any pattern analysis regarding B58TU engine oil pump defects in the United States. - **Year:** 2022 - **Make:** BMW - **Model:** X5 - **VIN:** [XXX] - **Mileage:** 39,500 - **Component:** Engine and Engine Cooling (or "Engine Oil System" if listed separately) - **Attachments:** RealOEM.com 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

The contact owns a 2022 BMW X5. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the rear of the vehicle. There was no warning light illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the transfer case fluid needed to be replaced three separate times. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer where it was diagnosed again and determined that the transfer case fluid needed to be replaced. The transfer case fluid was replaced; however, the failure persisted. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 38,000.

The high-voltage battery system (this is a plug-in hybrid) began intermittently displaying a "battery not properly charging" warning approximately 6 months ago; the issue would resolve after plugging in and charging. On July 14, 2026, while driving, the vehicle displayed a "critical battery failure - pull over immediately and drive slowly" warning. The driver pulled over and shut off the vehicle; the warning cleared and the car appeared to drive normally afterward. This warning recurred several times over the following weeks under the same pattern. On August 6, 2026, the same critical battery failure warning appeared while driving; this time steering feel and drivetrain response were abnormal, and the air conditioning and several electronic features stopped working. Our safety, and the safety of other drivers on the road, was put at risk by the sudden loss of full vehicle control while in motion. The vehicle has been at an authorized BMW dealership for inspection since August 7, 2026; a full diagnosis is pending. Dealer service staff independently remarked that two other BMW X-series plug-in hybrids came in that same morning with the identical warning and symptoms, suggesting this may be a widespread component defect rather than an isolated issue.

Over the last approximately 20,000 miles or so I've noticed a studder/shaking of the vehicle when turning and/or accelerating at slow speeds, in particular, while the car is cold (not warmed up). I change the transfer case fluid about 5,000 miles ago and the problem did not resolve. I now see that there is a class action lawsuit against BMW for known failure of the transfer case. I would like my problem noted for the record and hopefully action by BMW.

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 NHTSA 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.

On July 8, 2026, the vehicle unexpectedly stalled while I was driving in the middle lane on the I-95 highway, creating a safety concern. There was complete loss of engine power and low power to steering. The vehicle had to be towed to BMW of Peabody, Massachusetts. The vehicle had 30850 miles during the incident. During the inspection at service centre, I was informed that the safety fuse box and 12V auxiliary battery had failed which stalled the vehicle.
