2016 BMW X5 Complaints

The High-Pressure Fuel Pump (HPFP) on my vehicle has experienced a catastrophic premature failure for the second time, presenting a severe and immediate safety hazard. This vehicle was previously serviced under NHTSA Recall 21V-586 in 2022 at 66,165 miles, during which the original defective fuel pump was replaced by an authorized BMW dealership. At approximately 123,000 miles, the replacement pump failed while the vehicle was in operation. When these high-pressure fuel pumps fail, they cause sudden engine stalling, a complete loss of propulsion while driving, and a loss of power-assist for steering and braking. This creates an immediate risk of a high-speed collision on public roadways, especially during highway transit. Furthermore, failure of this component can lead to internal mechanical destruction, creating a potential fuel leak or fire hazard. Because a replacement part mandated by a federal safety recall has failed in the exact same manner after limited mileage, the remedy provided under Recall 21V-586 is demonstrably inadequate to permanently resolve this safety hazard. BMW is currently refusing to cover the repair because the vehicle is just past the 120,000-mile extended warranty limit, leaving a known, recurring safety defect unaddressed. I am filing this complaint to urge NHTSA to investigate the failure rates of BMW's replacement recall pumps, as the current remedy does not guarantee long-term vehicle safety.

2016 BMW X5 xDrive40e. Experiencing intermittent/sudden drivetrain malfunction warnings. Vehicle loses power or enters limp mode while driving. Max eDrive / electric drive becomes disabled even with battery charged. Multiple warning lights appear. Issue appears related to the hybrid system (possible EME, SME, Safety Box, or high-voltage battery faults). This creates a safety risk because power can be lost unexpectedly while moving. Mileage at time of most recent occurrence: 126,500. Problem first noticed 118,000.

The contact owns a 2016 BMW X5 PHEV. The vehicle was serviced under NHTSA Campaign Number: 24V608000 (ENGINE AND ENGINE COOLING, ELECTRICAL SYSTEM), but the failure persisted. The contact stated that a month after the repairs were completed, the coolant connector would stay on and drain the battery. The contact stated that after the vehicle was turned off at night, the coolant connector overheated and the battery drained. The contact needs to jump-start the battery every day. The vehicle was taken to the dealer, and the dealer refused to repair the vehicle, stating that it was already repaired. The contact stated that the coolant connector damaged the EME (Electrical Machine Electronics). The dealer confirmed that the problem may be EME. The vehicle remained at the dealer unrepaired. The contact stated that the failure is worsening. The manufacturer was not made aware of the failure. The failure mileage was 114,865. 

I am having a high voltage system box fault. I am within warranty but the dealership is denying me. My in service date is 6-2016.

The component that failed appears to be the hybrid propulsion and charging system, including the high-voltage battery management system and/or integrated charging electronics. The vehicle will not accept a charge from any home or public charging source. The high-voltage battery was replaced approximately one year ago; however, the charging failure persists. The vehicle is available for inspection upon request. In addition to the charging failure, the vehicle displayed drivetrain malfunction and start/stop malfunction warnings. While driving on the highway at normal speed, the vehicle lost power and stopped, creating a hazardous situation in active traffic. This sudden loss of propulsion placed my safety and the safety of other drivers at risk, as surrounding vehicles were traveling at highway speeds. Prior to the failure, warning messages appeared intermittently, including charging system faults and start/stop malfunction alerts. These warnings began approximately one year ago around the time the charging issue started. The vehicle was previously serviced and the high-voltage battery was replaced; however, the underlying issue was not corrected. The root cause is UNKNOWN, but the symptoms suggest a failure within the hybrid control system, charging module, DC-DC converter, or related electrical components. The failure has been persistent and unresolved. I am concerned that defects within the hybrid propulsion system may lead to additional sudden loss of power events.

Subject: Consequential Damage and Failure of Remedy regarding Recall 24V-608 Incident Description: "I am reporting a failure of the manufacturer to provide an effective remedy for Safety Recall 24V-608 (Electric Water Pump) and subsequent consequential damage to the High-Voltage battery system. In September 2023, at approximately 78,000 miles, this vehicle exhibited 'Drivetrain Malfunctions' including Fault Code 0x222626 (EME: internal fault - active short circuit requested) and 0x22271C (Overvoltage in intermediate circuit). The BMW dealer (Fields BMW) failed to diagnose the root cause and instructed me to 'keep driving'. Since the release of Recall 24V-608, it is clear these 2023 faults were early indicators of the coolant pump short-circuiting. This persistent electrical instability has now resulted in a permanent failure of Cell Supervision Circuit #3, causing the high-voltage contactors to open and leaving the vehicle disabled. The dealer is currently attempting to charge for diagnostics and battery removal. I am asserting that the lack of a timely remedy for the coolant pump (which was only recently shielded per the recall) caused a power surge that 'fried' the internal battery circuitry. This is a safety issue as the vehicle experienced a sudden loss of propulsion while in motion. I request that NHTSA investigate BMW’s refusal to cover battery failures caused by the electrical interference of the recalled coolant pump."

During a recent auto collision my airbags did not deploy. I swerved to avoid another vehicle entering the intersection from my left, he hit my rear left driver's side quarter panel and I subsequently hit a tree. This was noted by the paramedics first on scene as well as by the firemen and police when they arrived. I have notified BMW of North America, USAA insurance (my insurance company), and now you. The vehicle is a total loss and was towed to Leesburg Virginia by roadrunner wrecker service.com

Because of this water intrusion, the following safety systems have malfunctioned or failed: • ABS and DSC (stability control) warnings • Chassis stabilization warning • Frontal collision and pedestrian warning malfunction • Airbag system warning • Loss of audible warning tones • MOST bus communication failure • Electrical modules intermittently shutting down or throwing codes These failures affect braking, stability control, crash avoidance, and driver alerts, creating a significant safety risk while driving. This is not normal wear or maintenance. Many BMW owners have reported the same issue: clogged or poorly designed sunroof drains that route water directly into areas containing critical electronics. Once water reaches these modules, it causes electrical shorts and safety system failures that require expensive repairs. BMW dealerships typically diagnose this as “water damage,” but the location of the drains and the placement of the electronics indicate a design flaw that allows a simple drain issue to disable major safety systems. I am filing this complaint because the water intrusion should not be able to cause total failure of ABS, DSC, collision warning, and airbag-related systems. This is a safety-related design defect, not wear and tear. I request NHTSA review and investigate BMW sunroof drain failures and their impact on essential vehicle safety functions.

I am reporting a safety issue related to the BMW recall 18V-755 affecting the EGR cooler on my 2016 BMW X5 diesel. My vehicle experienced symptoms consistent with a failing EGR cooler, including coolant loss and engine warning lights. Despite this recall being active for my model and VIN, BMW has denied coverage, stating either that the cooler was already replaced twice or that my vehicle is not eligible—without providing sufficient documentation or explanation. I am concerned that the recall remedy was not properly applied or that faulty replacement parts were used. I am requesting that NHTSA investigate whether BMW is properly honoring recall 18V-755 and ensuring safe, effective remedies are provided to affected customers like myself. I also request investigation into the lack of transparency and failure to document completed recall work. My VIN is [XXX] , and I can provide dealer records, service history, and diagnostic reports upon request. * What component or system failed or malfunctioned, and is it available for inspection upon request? EGR Cooler, it is available for inspection. * How was your safety or the safety of others put at risk? The vehicle is now showing dangerous symptoms consistent with a thermal event risk, which this recall specifically warned about. The EGR cooler is leaking coolant into the intake system, which can mix with soot and lead to engine fires, according to BMW’s own technical documentation. * Has the problem been reproduced or confirmed by a dealer or independent service center? Yes and the cooler has been replaced twice. * Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It has been inspected at Fremont BMW once, Valley BMW twice. * Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, low coolant warning, loss of coolant with no leaks. Problem first occurred April 2024 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION AC

1) Crankshaft Sensor MIL Light 2) Drive train malfunction, 3) Start and Stop malfunction, 3) MIL for Catalytic convertor 4) MIL light for Catalytic Convertor & O2 sensor failure. The Vehicle has (97,000 K), and the BMW dealer would not cover the costs. However there's TSB published for this vehicle, yet its not being honored by the dealer who claims that the Emissions warranty expired after 8 years or 80,000 miles.
