2014 BMW 335I Xdrive problems

“After the car is shut off, the coolant pump will stop with the car but after a min the car will stay off but the coolant pump will kick on. Runs until battery is drained. I do understand there is a feature to circulate the coolant so help mitigate burn/hot spots but this continues until the battery is disconnected by ECU. Then it won't start because the battery is too low. Ongoing issue for the past 2 years now, happens intermittently. Frequency is random but happens more when it's cold out. But average happens a few times a week when cold out, sometimes it runs well for a few weeks then starts happening again. We had tried to troubleshoot by BMW but no luck. They have replaced battery, alternator, have tried to diagnose about 4 times now but they haven't fixed it since they can't replicate at the BMW Shop. I can hear the coolant pump running as well as feel the water moving. Also tested by Fluke Meter, it drains at about 40 amps (at 12 volts) when this happens, with the car off. Doing anything (opening doors, trunks, locking, unlocking, stops it for a minute but then pump starts again). No errors pop up for it except when the battery is low and then error…”

“EVERY TIME I GO FROM I93 MASS TO I90 HWY ON THE EXIT MY CAR SHUTS OFF FOR 3SEC AND RESTARTS THE ELECTRONICS. NOT SURE WHAT DEFECT OR SENSORS ARE IN THE AREA THAT CAUSES THIS MALFUNCTION. BUT THIS ONLY HAPPENS WHEN I TAKE THE SAME EXACT EXIT EVERY SINGLE TIME.”

“THE SYMPTOM: THE CAR MISSES OR SHUTTERS UNDER LOAD. THE DEALERSHIP INFORMED ME THAT THE CAR NEEDS A NEW TRANSFER CASE. THE VEHICLE HAS 80K MILES. THIS IS A MAJOR DRIVETRAIN FAILURE IN MY OPINION FOR A CAR OF THIS AGE WITH AVERAGE MILES AND CONTINUALLY SERVICED BY THE DEALERSHIP AND DRIVEN BY TWO PEOPLE. TODAY I READ ABOUT A RECALL FOR A 2014 MODEL 328D THAT REQUIRES REPLACE THE CONSTANT-VELOCITY JOINT AND INSPECT THE TRANSFER CASE, REPLACING IT IF NECESSARY. I SUSPECT THE SAME FAULTY PART COULD ALSO BE THE CAUSE OF MY NOW FAULTY TRANSFER CASE.”

“SUBJECT: Catastrophic Steering Failure and Erroneous Safety Recall Notification - 2014 BMW 335i 105,000 milles INCIDENT DESCRIPTION: While driving, the vehicle completely lost steering control. The electronic steering rack disengaged due to a failure in the aluminum mounting bolts. This incident resulted in a near-fatal accident in which the vehicle almost left the road and fell into a ravine. I have 360-degree camera video showing my steering wheel locking up and me struggling to survive. If you contact me, I can provide the video evidence. TECHNICAL BASIS: This failure matches the criteria described in BMW Technical Service Bulletin TSB 01 15 16 (and the previous NHTSA recall 14V-632), regarding corrosion and shearing of the aluminum bolts of the EPS (Electronic Power Steering) system. SAFETY REPORT VIOLATION (CRITICAL): The primary concern of this investigation is a significant discrepancy in the safety reports. When checking the official NHTSA.gov portal for this specific VIN, the system shows "0 open recalls." Similarly, the BMW recall portal also shows 0 open recalls. However, a thorough search of the history through third-party vehicle audit systems…”

“I WAS DRIVING ON THE HIGHWAY AND THE CAR WAS READING THAT IT HAD GAS, THEN SUDDENLY IT CAME TO A STOP, ON THE HIGHWAY, THE CAR WAS TOWED TO THE DEALER, AND IT WAS FOUND THAT THE FUEL LEVEL SENSOR HAD DIED MAKING THE CAR THINK IT HAD GAS WHEN IT IN FACT HAD NONE. THE DEALER WANTS TO REPLACE THE ENTIRE TANK FOR $2700, THIS ISSUE IS INCREDIBLY DANGEROUS AS IT CAN LEAVE ANYONE STRANDED ANYWHERE. THIS CAR IS ONLY 6 YEARS OLD AND THIS ISSUE CAN BE FOUND ON BMWS MUCH OLDER THEN THAT. BMW KNOWS ABOUT THE ISSUE, THEY KNOW IT IS DANGEROUS AND THEY CHOOSE TO CONTINUE MAKING CARS WITH THIS IS ISSUE. AS FAR AS I CAN TELL BMW DOES NOT CARE ABOUT THE DRIVERS OF ITS CARS AND ONLY CARES ABOUT MAKING MONEY BY SELLING DEATH TRAPS TO PEOPLE. IF YOU WANT TO BE LEFT STRANDED AND RISK GETTING KILLED ON THE HIGHWAY OR GETTING STRANDED IN THE MIDDLE OF NO WHERE, BY A BMW. IF NOT, BUY A MERC OR AUDI. THIS ISSUE CAN HAPPEN IF THE CAR IS UNDER WARRANTY AS WELL. ANY BMW THAT USES THE GAS TANK FROM THE F30 3 SERIES IS EFFECTED, AS WELL AS BMWS AS FAR BACK AS THE E46. *TR”

“WAS DRIVING IN RAIN, STOPPED AT A RED LIGHT WITH START/STOP ENABLED AND IN STANDBY MODE. WHEN SIGNAL TURNED GREEN VEHICLE STRUGGLED TO COME TO LIFE AND STALLED WITH MESSAGE ON I-DRIVE SAYING DRIVETRAIN MALFUNCTION AND AFTER A FEW ATTEMPTS TO BRING THE ENGINE BACK TO LIFE WAS ABLE TO DRIVE THROUGH THE INTERSECTION AND PULL OVER TO THE CURB AFTER WHICH THE ENGINE WOULD STILL STRUGGLE TO IDLE AND TRANSMISSION REFUSED TO ENGAGE DRIVE MODE. HAD THE VEHICLE TOWED TO THE BMW SERVICE CENTER AND THEY SAID THE LOW PRESSURE FUEL PUMP FAILED AND REPLACED IT AND CLAIM THE ISSUE IS FIXED. *TR”
