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.
High pressure fuel pump replaced after the original recall and fail again 45k miles later during driving.
Fuel injectors, transfer case prop shaft.
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. ".
The engine light came on while I was 250 miles from home and on a Saturday. Was able to contact my dealer's service department who said to drive home and just monitor for any issues and hopefully it will be ok. I brought the vehicle in for diagnostic check following week. Faults were for the diesel particulate filter sensor and recommended $1300. Replacement. They couldn't tell me if this part would impair the driving ability of the vehicle, but the cost seemed excessive for a sensor so I haven't made the repair yet (nor driven far) pending checking more into this. They said the vehicle may go into limp mode at any time which would be a safety issue. This sensor has been on a limited warranty extension-10 years/120,000 miles for the same model/engine as mine for 2014-2015 models (mine is 2016). Sib010418 with 2016 x3 added in 2019. I have to ask why the 2016 yr with a faulty sensor like mine is not part of this extended warranty?? my vehicle has 80k miles and 8 yrs old. . And the dealer says the part is faulty.
According to the manufacturer sticker BMW X5 5. 0 gets 15/21mpg. I wish I get anywhere near that. I get about 11 average mpg. I took the car to the dealer twice and I called BMW north America and they said that is the way it is. You will never get what you see on the sticker. So when you buy a car never trust what they say on the sticker price.
