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.
