ELECTRICAL SYSTEM
Exposed junction box in engine bay as well as water leaking through yellow grommet destroying footwell electronics as well as shorting junction box in engine bay. Water ingress also leaking into glove box electrical fuses and components. Also water leaking into trunk shorting out telemetrics battery as well as fuses of passenger side trunk fuse box. My ac compressor also blew simultaneously. There’s an active TSB for other models facing the same issue and should also cover this model as well.

SUSPENSION
I took the car in for a service and mentioned that there is a slight vibration at highway speeds. The dealer performed wheel balancing and found that the issue was still there. Following this, a software update was performed and the issue was still prevalent. The final cause was identified to be the control arm bushings. The problem I see is that a number of bushings/rubber parts are failing in the vehicle and I am being asked to pay out of pocket for what I believe is a defective part/vehicle. In the first instance, the guibo/ flex disk had cracked which was replaced. These are parts that should not fail until about 80k miles while my vehicle only has 28k miles and is barely out of new car warranty.

STRUCTURE:BODY, VISIBILITY/WIPER
The dashboard has pulled away from the windshield and is rippling. If it continues it will obstruct my view. I think it would affect the airbags as well. I've seen another 640 with this same problem at the store. I am available for inspection, I also attached BMWs invoice to show it was diagnosed. No warning lamps. I also use the garage and a window shade if not in garage.

STRUCTURE:BODY
The car is leaking from the third rear brake light (at the rear roof of the car). It appears the seals and possible clips/fasteners have failed and water is entering the car during rain or water immersion from the rear brake light, to the back seat, trunk, and rear floor. There is now visible mold in the car.

POWER TRAIN
I took my vehicle for a regular oil change and vehicle check at 22000 miles. The service advisor performed a routine check and found that the driveshaft flex disc had multiple cracks. If the cracks expand, it could lead to a complete failure of the disc at which point the driveshaft was come loose and can cause an accident along with extensive underbody damage. I do not understand how a certified preowned vehicle with only 22000 miles can have such a major part defect.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
The contact owns a 2019 BMW 640i. The contact stated that after purchasing the vehicle, he noticed that the Back Over Prevention camera was inoperable. The vehicle was taken to the local dealer to be inspected. The dealer informed the contact that the vehicle was not equipped with the reverse camera and that there was an additional cost to install the Back Over Prevention system. The contact stated that the Federal Law stated that vehicles manufactured after May 2018 needed the Back Over Prevention camera to be installed as standard equipment. The contact was concerned that the vehicle was not safe to drive or to be resold without the Back Over Prevention camera installed. The vehicle was not repaired. The manufacturer was made aware of the failure but offered no further assistance. The failure mileage was 36,423.

UNKNOWN OR OTHER
BOTH DOORS FAIL TO UNLOCK WHEN THE POWER IS OUT. LIFTING THE INSIDE DOOR HANDLE DOES NOT UNLOCK THE DOOR. THEY ONLY WAY TO UNLOCK THE DOOR IS TO USE THE ELECTORNIC UNLOCK BUTTON. BMW SAYS AN ELECTRICAL COMPONENT HAS FAILED AND NEEDS REPLACING FOR THE MANUAL OPERATION TO WORK CORRECTLY AND WANTS $1300 TO REPAIR IT. THE DOORS SHOULD ALWAYS HAVE AN MANUAL EGRESS. IF THE CAR IS IN AN ACCIDENT AND LOSES POWER, YOU CAN NOT GET OUT. ANY DESIGN THAT REQUIRES POWER ASSIST TO EXIT THE CAR, CAN NOT BE CORRECT. WHAT WOULD HAPPEN IN THE CASE OF A FIRE?

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
ON 9/27/19 I LEFT THE GAS STATION WITH FULL TANK OF GAS AND STOPPED AT A RED LIGHT ON A BUSY ROAD IN RUSH HOUR TRAFFIC. THE LIGHT CHANGED GREEN MY VEHICLE SHUT OFF AND WOULD NOT RESTART CREATING A SAFETY HAZARD. I PUT THE GEAR IN NEUTRAL AND PUSHED OUT OF THE ROAD. A LIGHT CAME ON "AUTO START/STOP DISENGAGED." EVERYTHING ELSE POWERED (WINDOWS, RADIO, REAR SHADES, SCREEN, PHONE AND NAVIGATION, ETC.) AND WORKED SO THERE WAS NO PROBLEM WITH THE BATTERY. THE TOW TRUCK ARRIVED 1 HOUR LATER, THE CAR WOULDN'T START, LOCKED UP COMPLETELY AND THE GEAR WOULDN'T SHIFT. THE DEALERSHIP HAD MY CAR FROM 9/27-10/10/19. DIAGNOSED CAUSE: BATTERY OLD/WORN, REAR BRAKES AND OIL LEAKING. THE CAR WAS SERVICED. ON 10/13/19 THREE DAYS LATER MY CAR CUT OFF AGAIN IN THE MIDDLE OF THE ROAD AFTER BACKING OUT OF A PARKING SPACE, LOCKED UP IMMEDIATELY AND WOULD NOT START JUST AS BEFORE. THIS TIME THE CAR WOULD NOT SHIFT INTO NEUTRAL AND COULD NOT BE PUSHED OUT OF THE ROAD. I BLOCKED TRAFFIC AND HAD TO WAIT ONE HOUR AGAIN FOR ANOTHER TOW TRUCK TO TOW MY VEHICLE BACK TO THE BMW DEALERSHIP. JUST LIKE BEFORE EVERYTHING ELSE WORKED (A/C, WINDOWS, LIGHTS, RADIO, BLINKERS, POWER SEATS, DISPLAY PANEL, ETC.), SO ONCE AGAIN IT WAS NOT THE BATTERY. AGAIN A SAFETY HAZARD WAS CREATED WITH ONCOMING TRAFFIC TRYING TO AVOID HITTING ME. IT WAS DARK, I WAS ALONE AND STOOD OUTSIDE THE CAR TO WAVE VEHICLES TO GO AROUND PUTTING MY PERSONAL SAFETY IN JEOPARDY. ON 10/22/19 I HAD TO CALL THE DEALERSHIP AND ASK FOR AN UPDATE ON MY CAR BECAUSE I RECEIVED NO COMMUNICATION AT ALL. THE DIAGNOSED CAUSE: FUEL PUMP REPLACEMENT AND THE FUEL PUMP CONTROL UNIT: EKPS FAILED BY EXCESSIVE AMPERAGE DRAW FROM THE FAILED FUEL PUMP. SAME PROBLEM, BUT TO REPAIR THIS TIME THE COST IS OVER $1500.

SERVICE BRAKES, ENGINE, FUEL/PROPULSION SYSTEM
TL* THE CONTACT OWNS A 2013 BMW 640I. WHILE THE VEHICLE WAS STOPPED AT A RED LIGHT, THE ENGINE WOULD NOT AUTO ECONO RESTART AND HAD TO BE PUSHED OFF THE ROAD. THE VEHICLE WAS TOWED TO TOM BUSH BMW JACKSONVILLE (9875 ATLANTIC BLVD, JACKSONVILLE, FL 32225, (904) 371-4790) WHERE THE BATTERY AND BRAKES WERE REPLACED. THE DEALER ALSO STATED THAT THE OIL FILTER GASKET WAS LEAKING. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED THREE DAYS LATER. THE CONTACT RESEARCHED THE FAILURE AND FOUND THAT THERE WAS AN INTAKE FUEL FAILURE CAUSED BY UNDER VOLTAGE AND THE FUEL PUMP CONTROL UNIT FAILED FROM INSUFFICIENT AMP ELECTRICAL POWER. THE CONTACT CALLED THE SAME DEALER AND WAS INFORMED THAT THERE WAS NO RECALL COVERAGE; THEREFORE, THE CONTACT WOULD HAVE TO PAY OVER $3,600 FOR THE REPAIRS. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 71,519.

WHEELS
THE REAR TIRE WAS LEAKING CAUSING AN UNSAFE ROAD CONDITION. WHEN THE TIRE WAS INSPECTED IT WAS FOUND THAT THE WHEEL HAD A CRACK IN THE SUPPORT DUE TO A DEFECT IN DESIGN. THE DEALER STATES THAT MANY OF THE 5 AND 6 SERIES WITH THIS WHEEL HAVE ISSUES AND OFFERED ME A "WARRANTY PACKAGE" FOR THEM FOR $1700. WHEN DOING RESEARCH ONLINE THIS IS A COMMON PROBLEM AND A CLEAR SAFETY ISSUE. WHEN USED WITH RUN-FLATS (WHAT THEY SUGGEST AND REQUIRE) THE WHEEL TAKES TOO MUCH STRESS AND ULTIMATELY CRACKS. MY VEHICLE HAS LESS THAN 25,000 MILES ON IT AND IT HAS A CRACKED WHEEL WITH NO REASON. THIS IS A CLEAR SAFETY CONCERN AS A RAPID LOSS OF AIR IN A WHEEL MAY CAUSE LOSS OF CONTROL. IT HAS CLEAR CONCERNS FOR STOPPING DISTANCE AND AVOIDANCE AS WELL.

STRUCTURE:BODY
DRIVER DOOR OCCASIONALLY DOES NOT UNLOCK WITH THE DOOR HANDLE. STANDARD OPERATION IS TO PULL HANDLE TWICE TO UNLOCK AND OPEN THE DOOR. THIS DOES NOT ALWAYS WORK, AND I CAN'T GET OUT OF THE CAR, WITHOUT FINDING THE KEYFOB, OR USING THE CENTRAL LOCKING BUTTON ON THE DASH. THIS IS A SAFETY ISSUE. IF THE BATTERY WERE TO FAIL, OR IF IN AN ACCIDENT AND THE POWER IS LOST, THE DOOR WON'T OPEN. I HAVE VIDEOS OF THE FAILURE. THIS OCCURS WHEN PARKED, VEHICLE IS TURNED OFF, AND ATTEMPTING TO EXIT THE CAR. IT HAS OCCURRED AT HOME, AND AT SEVERAL OTHER LOCATIONS. HAS OCCURRED TO ME BETWEEN 06-2018 AND 9-2018, AND WEATHER HAS NOT BEEN COLD.
