The contact owns a 2019 BMW 540i. The contact stated while driving at various speeds, the vehicle stalled without warning while depressing the accelerator pedal. The contact stated that while attempting to park the vehicle, the failure recurred. The contact continuously depressed the accelerator pedal and the vehicle lunged forward and collided with a barrier and crashed into his neighbor's vehicle. The air bags failed to deploy upon impact. The contact was not treated for any injuries. A police report was not filed. The contact had taken the vehicle to an independent mechanic who discovered that the lower section of the accelerator pedal was fractured. The manufacturer was notified of the failure and agreed to pay for a portion of the repair. The contact received a letter that stated that the manufacturer agreed to pay for the accelerator pedal replacement however, by accepting the payment, the manufacturer would absolve themselves of any responsibility for any damages caused by the defective accelerator pedal. The contact had not agreed to the terms of the agreement of the letter. The vehicle was repaired out of pocket. The failure mileage was 18,000.

MY CHECK ENGINE LIGHT CAME ON FOR CHASSIS STABILIZATION AND DRIVETRAIN MALFUNCTION. I TOOK IT TO THE DEALERSHIP AND THEY TOLD ME THEY REPAIR WOULD NOT BE COVERED UNDER WARRANTY. DEALERSHIP ALLEGES A RODENT GNAWED ON A ENGINE WIRING HARNESS. FROM WHAT I GATHER FROM THE DEALERSHIP THIS OCCURS FREQUENTLY. THE MANUFACTURER IS AWARE OF THIS PROBLEM BUT HAS FAILED TO MAKE NECESSARY DESIGN CHANGES TO MAKE THESE WIRING HARNESSES INACCESSIBLE TO RODENTS. MY CASE IS NOT THE WORSE CASE SCENARIO BUT A FIRE COULD HAVE STARTED, MY VEHICLE COULD HAVE BECOME INOPERABLE AND CAUSE AN ACCIDENT WHILE OPERATING THE VEHICLE. I WOULD LIKE TO REQUEST FMVSS BE UPDATED TO ADDRESS THESE PRODUCT DESIGN DEFECTS. A WIRING HARNESS THAT CAN POTENTIAL DISABLE REGULAR FUNCTIONS OF THE VEHICLE COULD RESULT IN DEATH SHOULD NOT BE EASILY DISABLED BY A RODENT. *TR

I own a 2019 BMW 540 with B58 engine and I have begun noticing abnormal rattling noise from the engine area, which may indicate early stage failure of the oil pump assembly. There are widespread reports from other owners of failure of the oil pump rotor housing/adjusting ring due to heat-related degradation of plastic components. Failure of this component can lead to sudden loss of oil pressure, drivetrain malfunction warnings, and ultimately engine seizure while driving. Sudden engine failure at speed presents a significant safety hazard due to loss of propulsion and potential inability to maneuver out of traffic. BMW has reportedly updated the oil pump design to an all-metal version around mid-2020, suggesting awareness of a design failure. I am submitting this report as a potential early indicator before catastrophic failure occurs.

ON FRIDAY, 11/20/20, DRIVING ON INTERSTATE AT ABOUT 60-65 MILES SPEED, SUDDENLY WITHIN FEW SECONDS, THE SPEED DROPPED DOWN TO 35-40 MILES WITHOUT ANY BRAKING ACTION BY ME. IT SCARED THE HACK OUT OF ME. I BARELY MANAGED TO GET OFF THE DRIVING LANE. WHILE IN MY CAR, BWW SOS ON-CALL ( DON'T KNOW EXACT NAME) CALLED, AND ASKED ME IF I WAS OK. THEN, THE OPERATOR GOT ROADSIDE ASSISTANCE OR THEIR MECHANIC ONLINE; HE TRIED TO DIAGNOSE THE PROBLEM. HE SAID IT WOULD NEED TO BE TOWED IN TO THE DEALERSHIP. THE OPERATOR ARRANGED FOR THE TOWING TRUCK; THE CAR WAS TOWED IN TO 'GLOBAL IMPORTS BMW' DEALERSHIP. THE SERVICE MAN TESTED THE CAR THE NEXT DAY, AND MENTIONED THAT HIS TEST DID NOT REVEAL ANYTHING BUT THOUGHT THAT THIS WAS AN UNIQUE SITUATION THAT REQUIRED BMW'S ENGINEER'S ASSESSMENT. THEN THE DEALERSHIP WANTED/ KEPT THE CAR OVERNIGHT, DROVE, AND TESTED IT THE NEXT DAY. THAT'S WHEN THEY FOUND THAT THE THROTTLE BODY ACTUATOR WAS FAULTY. THEY REPLACED. I HAD A SIMILAR PROBLEM, ON A SMALLER SCALE, EARLY THIS YEAR. I HAD TAKEN THE CAR TO THE SAME DEALERSHIP BACK THEN. THEY DIDN'T FIND ANYTHING UNUSUAL AT THAT TIME. THE SERVICE ADVISOR MENTIONED THAT VERY LIKELY THAT PROBLEM IN EARLY 2020 MAY ALSO BE DUE TO FAULTY THROTTLE BODY ACTUATOR.

The contact owns a 2019 BMW 540I. The contact stated while driving 60 MPH, the contact pressed the button on the gear shifter and the vehicle inadvertently shifted into NEUTRAL. The contact then shifted back into DRIVE. The contact continued driving with no further issues. However, the contact concern was that there should be no reason for the gear shifter to change gear with little to no pressure on the gear shifter from an inadvertent touch of the button on the gear shifter. The contact took the vehicle to the local dealer to be inspected however, the mechanic was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 43,500.
