What 123 owners told NHTSA about the 2015 BMW 328i

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 originating dealer (BMW of Henderson) in person on July 16, 2026, to coordinate a safety re-inspection under an active BMW North America Corporate Case. Dealership management actively obstructed the safety process, gave technically impossible justifications regarding the recall execution, and flatly refused to dispatch a complimentary flatbed tow. They attempted to hold the safety re-inspection hostage behind out-of-pocket customer towing costs and upfront retail diagnostic fees. There were 0 mechanical warnings or symptoms prior to the recall. The vehicle was meticulously maintained with 5,000-mile oil changes and a perfectly tight timing chain. The severe drivetrain malfunction warnings, violent front-end shaking, and terminal engine knocking appeared after picking up my car.

On November 17, 2025, my 2015 BMW 328i (VIN: [XXX] ) caught fire while parked, locked, and turned off inside my enclosed residential garage in Irvine, California. The vehicle had been parked for approximately 90 minutes prior to the incident. No flammable materials were stored in or around the vehicle. Responding police and fire personnel identified the vehicle itself as the source of the fire, with ignition originating in the engine bay. The building’s fire sprinkler system activated, and residents were evacuated due to smoke and fire conditions. No injuries occurred, but the incident posed a serious risk to life and property due to the residential setting. The vehicle was a total loss. While the exact technical cause of ignition could not be determined at the scene, first responders confirmed that the fire originated within the vehicle’s engine compartment. BMW of North America was notified of the incident and represented that an inspection would be coordinated. I remained in contact with all involved parties and relied on BMW’s stated intent to contact the tow facility directly to arrange inspection. Despite this, BMW did not make contact with the tow company prior to the vehicle’s disposal. After the vehicle had already been sold by the tow yard, BMW indicated that coordination had not occurred and that inspection was no longer possible, resulting in loss of physical evidence. This complaint is submitted due to concern regarding a vehicle fire occurring while the vehicle was not in operation, inside a residential structure, and due to the manufacturer’s handling of the matter in a way that prevented timely inspection and meaningful safety review despite early notification and cooperation.

Tire Pressure Monitor failure intermittently reported while driving. The error lights up on the dashboard. Sometimes the TMP resets without my resetting the system. I took the car to the dealer and was told nothing is wrong with the system. The dealer told me to drive the car more frequently. This has happened over the last several years. Driver's door intermittently fails to lock and/or will not open (intermittently) using the interior door latch handle mechanism. The door will unlock using the electronic locking and unlocking switch/button located on the center of the dashboard. The problem would be exiting the vehicle in an emergency without electrical systems functioning. This has happened starting in the first year of purchase - 2017 continuing through 2025.

NHTSA ODI 11696839

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
