2015 BMW 3 Series problems

“The engine intake tract, PCV infrastructure, and the main lower engine wiring harness loom failed due to improper reassembly during Federal Safety Recall 24V-608. The technician left the main intake coupler completely loose and spinning freely by hand, and left the MAF sensor crooked. This introduced a massive unmetered air leak and severe vacuum leaks. Simultaneously, the technician over-tensioned, pinched, or damaged the Cylinder 2 wiring loom components. The vehicle is currently parked dead and untouched at my residence, and it is 100% available for immediate federal or corporate inspection.The unsealed intake tract and damaged wiring harness caused the engine to run dangerously lean at highway speeds. This resulted in sudden, violent engine shuttering, rapid deceleration, severe mechanical engine knocking, and a terminal Cylinder 2 misfire. This component failure caused an immediate loss of vehicle propulsion on a high-speed public highway, creating an extreme risk of a high-speed collision and leaving the vehicle completely disabled. The issue has not yet been physically inspected by a third party because the vehicle is unsafe to drive. I went to the…”

“The contact owns a 2015 BMW 328I. The contact stated that while driving at 40 MPH, the vehicle caught on fire. The fire originated in the engine compartment. There were no warning lights illuminated. The driver was able to extinguish the fire. The vehicle was towed to the residence and was then towed to an independent mechanic, but the vehicle was not diagnosed or repaired. The vehicle was towed to the local dealer, where it was diagnosed with an electrical short circuit in the front water pump connector. The vehicle was not repaired. The contact associated the failure with NHTSA Campaign Number: 24V608000 (Engine and Engine Cooling, Electrical System). The manufacturer was notified of the failure, and a claim was opened. The failure mileage was approximately 110,000.”

“On [XXX], my 2015 BMW 328i xDrive (VIN: [XXX] , N20 engine, 124,250 miles) suffered a catastrophic engine failure while in operation. Component/System Failed: The timing chain guides and oil pump drive chain module failed. The plastic timing chain guide broke apart inside the engine. The vehicle was salvaged and is no longer available for inspection. Safety Risk: The oil pressure warning illuminated suddenly while driving at highway speed with no prior warning. Sudden loss of oil pressure and engine power while operating a vehicle at speed creates a significant risk of accident, loss of vehicle control, and injury to the driver and others on the road. Confirmed by Service Center: BMW of Springfield, New Jersey performed a formal diagnostic confirming timing chain guide failure and oil pump drive chain failure. A BMW mechanic performed a scope inspection on April 3, 2026 visually confirming the broken plastic timing chain guide. Repair estimate: 7,191.42. Inspected by Others: The vehicle was inspected solely by BMW of Springfield. No police, insurance, or manufacturer representatives conducted a separate inspection. The failure mode is consistent with the defect…”

“On XXX, while driving on Interstate XXX with my family near [XXX], the engine shut off and the vehicle lost all power. The event was preceded by a "Reduced Power" error displayed on the dashboard. Traffic was moderate and I was able to pull over to the right shoulder. The engine shutting off while on an interstate highway is obviously quite dangerous. After waiting for a few minutes I was able to restart the car and continue travel. I took my vehicle to a mechanic and several potentially relevant codes were found: 110001: Cylinder injection shutdown: pressure too low in high pressure system 11A002: Fuel high pressure, plausibility: pressure too low 481B03: EKPS control current too low Review of the issue and codes with the mechanic and internet forums indicates the fuel pump control module (EKPS) is failing. This can be exacerbated by hot weather. A failing EKPS can cause sudden stalling at any time, including at highway speeds, making the vehicle unsafe to drive until repaired.”

“My 2015 BMW 328i xDrive (VIN [XXX] ) experienced an engine-compartment fire that began shortly after coolant sprayed from the front of the vehicle. This incident occurred before BMW’s official recall announcement for NHTSA Campaign 24V-608 / BMW 24V-608:474 (Safety: Engine Coolant Pump Electrical Connector). The fire originated near the coolant pump area, consistent with the recall’s described defect involving electrical shorting and overheating at the pump connector. The vehicle was declared a total loss by my insurance company. I believe this event was caused by the same defect identified in the recall and request that this incident be investigated and documented under campaign 24V-608. Supporting photos and insurance documentation are available upon request.”

“i went online because i was having troubles with my vehicle battery alternator and other electronics , i found out other bmws with the same symptoms as my car led to having a bad footwell module , currently interior lights work when they want to if any constant battery dying from lights not turning off none of the parking sesnors work no back up camera the rear windows do not work some times the power mirrors work , i have had the vehicle tested with a new alternator and battery each window motor works its the footwell module but i noticed that the extended warranty is for 2014 and older models sadly it also effects the 2015 models as well”
