UK DVSAReplace the Engine Starter Motor
Risk: The Safety Recall relates to the engine starter motor. The fault relates to the RSW22 starter RWT (reinforced water tightness). It was found that with RWT starters an increased abrasion of the magnetic contact can cause the growth of deposits at the lowest point of the relay interior. This in turn may increase the relay contact resistance resulting in false starts or even causing short circuits and possibly a thermal reaction. In case of a short circuit the possibility of a thermal event cannot be excluded. This may happen while attempting to start the vehicle or while driving due to vibrations causing a short circuit due to moving deposits.
Fix: On the affected vehicles the starter motor will be replaced with a variant by another supplier with a different design. Until the repair has been completed it is recommended to not leave the vehicle running unattended after starting the engine.

Risk: On certain vehicles the Body Domain Controller (BDC) control unit may have an incorrect setting applied to it.
Fix: Conduct a check of the settings and if necessary perform a reset on the BDC control unit.

These deposits may increase relay contact resistance, leading to starting failures or short circuits. If a short circuit occurs, either when attempting to start the vehicle or while driving due to vibration-related movement of the deposits, it could cause a thermal event and increase the risk of fire.

Both the driver and passenger seatbelts have been replaced due to wear and shredding. Dealership has told us it was caused by the seatbelt extender “becoming delaminated” in both cases. This seems like a design flaw given the age and relatively low mileage (30,800). The more severe damage in the photograph is the driver’s side. The other is the passenger side that we proactively had replaced while the vehicle is still under its new vehicle warranty.
The contact owns a 2023 BMW 430i. The contact received notice of NHTSA Campaign Number: 26V056000 (Electrical System). The contact stated that that on several occasions when starting the vehicle there was a hesitation while starting the vehicle. The contact added that the hesitation while starting the vehicle using the key fob was more prevalent. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 39,000.
I purchased my 2023 BMW 430i, coupe, X-Drive brand new on 04/14/2023 from BMW, Wesley Chapel Florida. On 05/14/2025, I observed my driver's side front seat belt to be extremely frayed and in an unsafe condition (see photo 05142025) and reported it to BMW Wesley Chapel immediately. The service manager advised me this was very unusual and he has never seen this condition before, but explained BMW Warranty will likely call it "normal wear and tear." The vehicle is under factory warranty for 5 years or 50K miles and it should be noted at the time of this incident the vehicle had 34,758 miles. BMW…
We were driving the vehicle on a vacation, and am error came on that the gear was malfunction and parking will disable vehicle. At this fine, we kept trying to clear the message to be able to view navigation, and error message kept coming back making it impossible to drive. We then parked the vehicle and had vehicle towed. Tow could not put car in neutral, and had to physically pull vehicle on to flatbed. Service advisor said water from cup holder area got into the controller.
