What 151 owners told NHTSA about the 2014 BMW 328d

1.) The Bosch CP4 High-Pressure Fuel Pump (HPFP), OEM part number 13517824477 / 0445010517, failed catastrophically. This is the factory-installed pump on the 2014 BMW 328d equipped with the N47 diesel engine. Upon failure, the pump's internal cam and roller assembly disintegrated, releasing metal shavings throughout the entire fuel system — contaminating the fuel lines, injectors, fuel rail, and fuel tank. The vehicle will not start. The failed pump and contaminated fuel system components are available for inspection upon request. 2.) The vehicle experienced a sudden, complete loss of motive power with no prior warning, rendering it unable to start or operate. This type of failure — as documented in NHTSA Engineering Analysis EA23-001 — is known to also occur while the vehicle is in motion, causing unexpected engine stall at highway speeds with no ability to restart. This creates an immediate risk of rear-end collision, loss of vehicle control, and danger to other motorists. The failure provides no warning to the driver and cannot be prevented through normal maintenance practices. 3.) Yes. The high-pressure fuel pump failure and presence of metal shavings throughout the fuel system have been confirmed by a BMW authorized dealership. The dealer has documented the failure and provided a repair estimate for full fuel system replacement — including the HPFP, injectors, fuel lines, and tank cleaning — at an estimated cost of $10,000–$15,000. BMW of North America has declined warranty coverage citing that the vehicle has exceeded the 120,000-mile threshold under Recall 21V-586, despite this being the identical defect covered by that recall. 4.) Yes. The vehicle has been inspected by a independent BMW Specialist 5.) Check engine light was present

The fuel system has failed. The car shut off in the Baltimore harbor tunnel twice completely stopping traffic and creating a very hazard situation. One of those two times the semi truck behind me had to slam its brakes. When the car shuts off you must come to a complete stop and turn the car completely off. After restarting the car is in limp mode with reduced power. The incident has happened about 6 other times. Every time it happens I have feared my safety, especially if there is no shoulder to coast the car in to park. Independent service center has replaced three sensors related to fuel pressure system which did not fix. The vehicle and component has not been inspected by manufacture, police, insurance representatives or others. The manufacture claims there are no recalls on the fuel system of the vehicle. The vehicle has a rebuilt title from a small accident because no parts were available during covid so the insurance wrote the car off. The car was inspected by the state of North Carolina and deemed safe for the road. There is no indication that the car is going to shut off. It just cuts power and shuts off. After restarting the car, it will show a check engine light on the cluster and a drivetrain error on the infotainment screen . The error code p0087 Fuel/rail system Pressure - too low bank 1

I am reporting an emissions-related malfunction that occurred a very short time after BMW performed the EGR cooler recall and updated the DDE software on my vehicle. Shortly after the recall work, the vehicle began showing DDE fault code 2BB300 – Particulate Sensor Measuring Electrode, Self-Diagnosis, which triggered the MIL. This issue did not exist at any point before the recall. Although my vehicle is now older than 10 years, the critical concern is that this emissions-related failure appeared soon after the recall intervention, indicating a potential recall-associated defect rather than normal age-related wear. The fault was diagnosed at BMW West Houston, where it was confirmed; however, I was told no warranty or goodwill support could be provided due to vehicle age, despite the timing suggesting a recall-related cause. BMW’s emissions warranty extension bulletin (NHTSA TSB ID: MC-10160282-9999) lists particulate sensor failures (2BB700–2BA200) as known issues. Many BMW diesel owners have reported similar particulate sensor faults shortly after the EGR cooler recall and related software changes, suggesting a broader pattern. If the EGR recall or subsequent software calibration is leading to particulate sensor failures and MIL activation, this may represent a post-recall emissions defect affecting compliance. I request that NHTSA evaluate whether the EGR recall may be contributing to widespread particulate sensor failures. Vehicle Information: – 2014 BMW Diesel – Fault Code: 2BB300 – Failure occurred a short time after the EGR cooler recall & software update – Diagnosed at: BMW West Houston Thank you for your attention.

The primary failure involves the EGR cooler system covered under Recall 21V-907, with consequential damage to the intake system, including intake air leaks, charge pipe failure, displaced turbo-to-DPF V-band clamp, brittle/cracked fuel lines, and intake system integrity loss. Yes — the vehicle and all affected components are available for inspection upon request The EGR cooler internal leak defect and intake system failures create risk of engine overheating, thermal degradation, loss of engine power under boost, exhaust gas leakage, and potential fire hazard, which can cause unsafe driving conditions and sudden loss of vehicle performance The vehicle was presented to a BMW dealership, and the recall defect was acknowledged. The dealer confirmed that any decisions regarding inspection and repair must come from BMW corporate. The dealership refused to inspect or evaluate the recall-related failures pending corporate authorization. No. BMW of North America has not authorized inspection or evaluation. The dealership also refused to inspect the vehicle pending corporate direction. Yes. Symptoms included audible air leaks, intake pressure loss under boost, performance degradation, and component failures occurring both before and after recall repair attempts. These symptoms developed during the period when the vehicle was operating under a known recall-defect condition and continued after recall repair.

I was driving to work when my engine started sputtering acting like it was about to turn off. I quickly pulled off to the side of the road and as soon as I did, the engine stalled and turned off. I'm lucky that I pulled off the road because if it turned off while on the road I could have caused an accident. The car is no longer able to turn on. I had to get it towed to my work where I had a mechanic look at it. They said they believe the high-pressure fuel pump failed. I researched this online and saw that there is an open NHTSA campaign for it (#21V586000). My car is a 2014 BMW 328D with the N47 engine. It seems that my car would fall under this recall but when I put in my VIN it says it does not have a match for it. How is it possible for my vehicle to be accepted into this recall.

Faulty fuel injectors , that are known to prematurely fail. The same injectors are covered by BMW for model years 2015-2018 Under NHTSA SIB 01 09 19. My complaint is my 2014 has the same fuel injectors as the 2015-2018 that are known to be faulty and yet it is deliberately excluded from the same “limited warranty extension “

While driving our 2014 BMW 328d the engine misfired then stalled on the highway. This was a very dangerous and frightening scenario trying to push it off of the roadway while my wife and children were inside the car while highway traffic on the I-15 interstate rushes by. I was not able to restart, so we had it towed to our local BMW shop. Diagnosed as High Pressure Fuel Pump complete failure. Metallic debris throughout the entire fuel system, lines, tank filter, injectors, pumps. No check engine light or any prior warning. Many of the components have already been disassembled to determine the extent of damage, and all the components are currently with the vehicle, and available for inspection. The vehicle has been at the shop since the end of June. Some parts were initially ordered then all repairs put on hold while awaiting direction/ recall approval from BMW of North America. 5 months later we are being told this vin does not qualify for the safety recall. We can not afford the cost of the repairs and they will likely exceed the value of the car. We also need to remove it from storage at the shop it was towed to, and take it somewhere else while this is sorted out.

After a drive from Denver to Breckenridge on snowy roads the car was parked in an unplowed parking space. When the car was moved 1 hr later the car had no ABS--flashing on dash, no traction control--flashing on dash and steering was ineffective. Car was only drivable by backing into a space. 20 hrs later the car was to be moved again...again, everything flashed on dash...no ABS, no traction control, drive train failure and car just slid. Steering was totally ineffective. Car was pushed by people on both sides until dry pavement was reached. Car was restarted and I resumed driving on dry pavement back to Denver. Had car "read" by my mechanic and then again by a BMW certified mechanic. No codes were available! The speculation was that my wheel sensors froze. If my Xdrive can't be driven in snow, what's going on. There were two drivers involved in this and both of us reported a total lack of control of the vehicle.

While driving my 328 XDrive, I went to make a left turn and hear a loud bang like I ran over a boulder or large object. Lost almost all power to the wheels and had to cost the car into a gas station. After which I had the car towed to BMW and was determined to be a failed transfer case at 123k on the OD. This seems to be happening to the older BMWs with the old transfer case. BMW knows this as they have since upgraded the transfer case and no longer sell the old one. This should without question be a recall for any 328d XDrive from this era.

The driver side door lock mechanism failed completely while the driver was in the vehicle, making it impossible to open the driver side door or exit the vehicle normally. Neither the interior door handle, nor the central power lock/unlock control, nor the remote key fob, nor the physical key inserted into the door lock from the outside can unlock the door. The driver was forced to exit the vehicle by moving the driver seat to an extreme aft position, then climbing over the center console into the passenger seat, to exit via the passenger door. If the power seat adjustment had been inoperable, egress would have bee significantly more difficult. If the driver had been involved in a collision, or otherwise needed to exit the vehicle very quickly, they would have been severely hindered from doing so. Inability to operate the driver side door represents a safety hazard to the driver. No warning messages or lamps were present in the vehicle before or after the door lock mechanism failure. The driver side door remains inoperable after completely switching off the vehicle ignition and turning it back on.
