Formal complaint regarding improper recall repair of a 2021 BMW X3 and request for assistance. Dear Administrator, I am writing to submit a formal complaint regarding my 2021 BMW X3 and the handling of a recall-related starter replacement performed by BMW of Gwinnett. After taking the vehicle in for the recall repair, I later became stranded out of state when the vehicle would not start. I paid 165 dollars to have my vehicle towed to BMW of Greensboro in Greensboro, North Carolina. That dealership has stated the starter was not installed correctly and that approximately 740 dollars is required to correct the problem. I am extremely concerned that a repair performed in connection with a safety recall was allegedly completed improperly. I am requesting assistance and appropriate review regarding the following matters. One, review of the original repair. Two, correction of the repair at no additional cost to me. Three, reimbursement of the 165 dollar towing expense. Four, prompt attention to this matter to resolve the alleged repair issue. Five, review of any potential safety concerns related to this reported installation problem. I relied on an authorized dealer to perform the recall-related repair correctly. Instead, I've experienced a breakdown while traveling, unexpected costs, and significant distress. Thank you for your time and consideration.

Active Grill shutter malfunction. Randomly the check engine light came on the code was for the grill shutter. Upon inspection the grill shutter is not closing. This was an extended warranty on several prior X3/ X5 models. This appears to be the same issue, I wanted to make BMW aware so they can reevaluate the extendeded warranty.

On XXX, while in the parking lot, after placing the car in 'park' I then placed the auto into 'reverse' to straighten out the auto in the parking in the space. However, the car automatically changed back to 'park.' Then tried to place the auto in 'drive' and again the the auto switched back to 'park.' I then turned off the engine and decided to begin the process again but experienced the same problem. After doing this once more and while the the auto was in the 'drive' position, and even though my foot was off the gas pedal, to my surprise the engine revered up with a rapid unintended acceleration. Before I could react, the auto went over the dividing curb and the parking island separating the row of cars. It then proceeded to slam into the auto in the parking space in front of my car before I could react. Extensive damage to both automobiles occurred. Both cars in now in their respective repair shops, which will be coved by my insurance. The accident occurred at the Gym located at [XXX]. The accident was reported toXXX and officer [XXX] badge # XXX responded. Their Accident Report will be available next week at the Englewood Police Department - report #XXX. Please let me know if any clarification is required. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am writing to report a known safety-related defect on my 2021 BMW X3, VIN [XXX]. 1 The vehicle was diagnosed at BMW of Manhasset, an authorized BMW dealer, with a coolant leak originating from the heat management module and oil filter housing. This is not ordinary wear and tear. BMW's own service bulletin SIB 11 10 25 identifies this failure mode as a known issue affecting B46/B48/B58-equipped vehicles, which includes my X3. 3 4 5 The same defect is also the subject of an active U.S. class action, XXX. v. BMW of North America, LLC (D.N.J.), covering the same engine families. This defect presents a genuine safety risk, not merely a cost issue. The oil filter housing's internal wall structures, which separate the oil and coolant passages, are prone to failing or warping, and the gaskets sealing those passages are prone to premature failure. When this occurs, coolant can leak into the oil sump or drain externally, which can cause sudden engine overheating and/or engine failure, sometimes within minutes of the leak developing. If oil escapes and contacts the hot exhaust, it can also create a fire risk. A vehicle experiencing this failure is not safe to continue driving, and the risk of sudden, catastrophic engine damage or fire warrants a recall rather than leaving affected owners to discover and pay for this known defect on their own.

There is an open safety recall for the engine starter on this vehicle. I contacted the local BMW dealer on 7/10/26 to have the recall fixed they advised me that they cannot address the recall because BMW North America has not sent the parts out for them to do so. I would like this on record in case there is any future damage to my vehicle due to the recall.

Lane keep assist performance has been degrading to the point that it very quickly disables itself when overcorrecting or an oscillation of the steering wheel is developed while system is trying to keep the car inside the lane (which eventually also disables the system). System always had a bit of “bounce” between the two sides of the lane and struggled to keep the vehicle exactly in the middle of the lane. But it is much worse now and I am now more often than not disabling it. System feels unsafe now. The KAFAS (camera) module is having random faults now that disable the system but go away and Lane Assist can be re-engaged without any change in the performance I described above. As an engineer I would simply call the Lane Assist control algorithm unstable with an oscillation that gets amplified. I’ve done simple tests where I center the vehicle inside the lane, engage the feature, and take my hands off the steering wheel (vehicle has some limited hands free capability—goal is to eliminate any disturbance from my hands to be the potential trigger for the oscillation). I used to be able to do this and now it rarely works and forces me to quickly take over. Another observation has been that the camera is also used to follow a vehicle ahead of me (in lieu of centering in the lane) and this rarely works now to the point of trusting it. Nothing recent has changed on the vehicle. At first I thought it may be a wheel alignment problem but when the camera module started to have sporadic errors I eliminated that root cause (recall that Lane Assist system always oscillated when engaged, but was definitely usable before). Seems like both problems originate at the camera module. Vehicle did have a windshield replacement and camera was recalibrated many months before this problem developed. Performance was the same immediately before and after replacement.

Filing regarding NHTSA Recalls 25V-636 and 26V-056. My 2021 BMW X3 M40i (VIN: [XXX] , built September 2020) contains the recall-affected starter part number ending in 997 — confirmed by a BMW Level 1 certified technician — not the non-recall part number ending in 505. BMW denied coverage based solely on manufacture date, with no consideration of the actual components installed. My vehicle displays an active fire risk. On April 30, 2026, my dashboard displayed Engine cannot be started, Starter system fault. Call Roadside Assistance, and Repeat start attempt — all photographed and timestamped. Fault codes 216119, 35AE00, and 8040A9 were confirmed by diagnostic scan. BMW of Catonsville (Work Order XXX) attributed the fault to the battery and charged me $280.50. I replaced the battery with a BMW OEM unit on May 13, 2026 at a cost of $590.31. On May 21, 2026, the identical starter fault returned — conclusively disproving the battery diagnosis and confirming the starter as the root cause. BMW denied recall coverage by phone through BMW of Catonsville. No written denial was provided. I am requesting NHTSA investigate whether the recall scope incorrectly excludes vehicles built with the recall-affected starter component, compel BMW to expand coverage to include my VIN, replace my starter at no cost, and reimburse my out-of-pocket costs of $870.81.
