Electrical System Problems of BMW X3 - part 2

When starting the vehicle, the message center displays "loss communications brake system control module a. " the vehicle losses power steering, speedometer indication, tire pressure monitoring, and stability control. There are numerous codes displayed for brake system, power steering, parking brake and stability control. This is the third time that this event has happened. Turning the vehicle off and restarting after approximately 1 hour the codes were clear and everything appears to work properly. This event occurs randomly and resets after the vehicle is turned off and restarted after a period of approximately 1 hour. The loss of power steering and speed indication is a safety hazard. I have been driving this vehicle when the power steering and speedometer stopped working. The steering requires a lot more effort to turn and you do not know the current speed of the vehicle. The BMW dealer charged us the customer for a software update to fix this issue. We are not confident that the vehicle is fixed because this is a random event. I believe this should be a safety recall. There is a recall on BMW 2023 and 2024 models for the same issue. The recall does not include the 2022 model at this time. Codes displayed: u0129, u0418, p15c9, p15c8, p15b9, p15b8, p0507, p0610, p152b, p152a.

The contact's daughter owns a 2013 BMW X3. The contact stated that the vehicle was included in NHTSA campaign number: 24v608000 (engine and engine cooling, electrical system). The contact took the vehicle to the dealer for the recall repair; however, the dealer found no signs of contamination and installed a water pump connector cap. The contact stated that a month after the repair, the engine was overheating while idling, and there was while smoke coming from the engine with an unknown warning light on the instrument panel. Due to the failure, the vehicle was towed to an independent mechanic, where the water pump and the battery were replaced. The mechanic informed the contact that the water pump connector cap was faulty and had caused the failure. The contact was reminded by his wife of the water pump recall and that the connector cap was replaced due to the recall. Despite the repair, the vehicle shut off soon after starting the vehicle. Due to the failure, the vehicle was towed to a BMW specialist, who discovered that an antifreeze leak had caused corrosion of several electrical wires inside the engine. The specialist informed the contact that the vehicle needed two engine wiring harnesses, an engine computer, and an ivm (integrated supply module). The manufacturer was notified of the failure, and the contact filed paperwork online to be reimbursed for the repairs made to the vehicle. The manufacturer denied the reimbursement because the vehicle had been serviced by an independent mechanic and not a dealer. The vehicle was not repaired. The failure mileage was approximately 100,000.

I believe there is a flaw in the architecture of start-stop technology in conjunction with the electronic shifting technology installed in cars today. . I have ran into this issue twice in a 18month period and I believe it is something the NHTSA should institute new requirements on car manufacturers. My wifes BMW X3 start stop technology has failed twice in 18months and that is not a big deal. Things break and need to be repaired but given the car can not be put in neutral it left us stranded unable to move the vehicle in the middle of the road until a tow truck could move us out of the road. I could have easily put the car in the neutral (if allowed) and pushed the car off to the side of the road out of traffic. Luckily in both occasions a police officer pulled up very quickly and was able to alert traffic there was a vehicle stopped in the middle of the road. I want you to imagine being in stop and go traffic on highway 95 and this happens. Then the traffic actually dissipates and your vehicl is in the middle lane on hwy 95 unable to be moved until a tow truck arrives and now the traffic is going 65-70 mph. The BMW X3 can not be place in neutral unless you go underneath the car in some sort of service panel. I do not believe given the mandate of auto-stop start on these new cars coupled with the inability to place cars into neutral is a good design point and I would hope the the NHTSA would mandate cars be able to put cars in neutral to avoid potentially catastrophic accidents on the highways across America. .

Beginning in July–August 2025, my 2019 BMW X3 (VIN [xxx] ) began experiencing multiple safety?critical system failures affecting federally regulated components. The rearview camera intermittently failed to activate and later stopped functioning entirely, resulting in loss of rear visibility required under fmvss 111. The emergency call (ecall) system displayed repeated malfunction warnings, indicating loss of automatic crash notification capability. The vehicle also displayed “driver assistance restricted,” “collision warning malfunction,” and pedestrian detection failure messages, showing that forward collision warning and related adas functions were not operating properly. During the same period, the telematics control unit (tcu) lost functionality. This caused loss of connecteddrive services, backend communication, remote diagnostics, remote status reporting, and safety?related over?the?air updates. These failures match known BMW defect patterns involving water intrusion into the antenna/telematics module and backend provisioning issues. I submitted a detailed written escalation to BMW of north America. BMW issued two brief responses on February 11–12, 2026 that did not address any of the safety issues, did not provide the engineering basis for excluding my VIN from the applicable recall, and redirected me to a dealer, which has no authority over recall determinations. BMW closed the case without providing any investigation results, defect determination, or technical explanation, contrary to obligations under 49 cfr § 573. These failures materially impair federally regulated safety functions, including rear visibility, collision avoidance, emergency crash notification, and telematics?based safety communication. The pattern suggests a potential broader defect affecting additional vehicles. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My X3 has 52,000 miles. During a recent road trip, an "emergency call system malfunction" message appeared. When I returned home, I took the vehicle to the dealership. The advisor said the shark fin trim is loose on the roof causing water ingress into the vehicle causing damage to the aerial antenna and the tcb unit. The tcb unit is also known as the telematics control unit that is responsible for vehicle safety and connectivity features, door locking mechanisms, and so on. The technician found faults in the aerial antenna and tcb. I understand from the service advisor that they see this fairly regularly. I have further learned that BMW issued a service information bulletin admitting the problem to dealers and telling them it was a manufacturing defect during the painting process and lists the parts needed to fix it. The quoted cost to replace the damaged components and install/seal a new shark fin was over $4,000 (almost 10% of the car's original price). BMW knows this to be a problem and I think there should be a safety recall for it, regardless of whether the car is out of its original warranty period.

One cell in the hybrid battery failed causing the car to go into safety mode. Battery assistance to the engine stopped and gas engine was the only source of power. Was told the car could be a fire hazard in this condition and required repairing the hybrid system.

Regarding sib 65 12 22, NHTSA id number 10227571, manufacturer communication number b651222. Summary: the seal of the roof-mounted antenna housing is separating from the vehicle. Affected products: (20) vehicle BMW X3 2018-2022 - BMW x4 2019-2022 - BMW x5 2019-2022 - BMW x6 2020-2022 - BMW x7 2019-2022 I would like to mention that, this issue was known by BMW and acknowledge as painting process deffect, BMW havent release a recall. BMW released on oct 2022 a BMW service information bulletin detailing a defect in the paint and sealant of the roof-mounted antenna housing, which can allow water to leak into the vehicle and damage electrical components, including the emergency call system and gps. Vehicles produced before January 10, 2022, are affected. The bulletin provides instructions for dealers to inspect for water ingress, remove the affected antenna housing, inspect the paint for separation on the sealing surface, and replace the housing if the paint is separating. Even when this production deffect main consequence is the damage of the telematics control unit (tcu) due to physical closeness and consequently failure of the vehicle’s emergency call system and other communication systems and gps. The bulletin only focus on replace of antenna and painting of area (approx cost $700) and doesnt mention any alternatives for solution to damaged tcu (approx cost $3000) and on top the solution mentioned is even more restricted to coverage under the terms of the BMW new vehicle limited warranty for passenger cars and light trucks. Please, respectfully request you to consider reviewing this situation due to affects 20 models and a considerable big amount of people.

The low-pressure fuel temperature/pressure sensor failed internally, causing diesel fuel to intrude via capillary action into the engine wiring harness and ultimately contaminate the digital diesel electronics (dde) control unit (ecu). The failed components (sensor, harness, dde) are available for inspection upon request at BMW of loveland, CO. My safety was put at risk in two primary ways: engine stalling risk: the dde is the engine control unit. As the fuel contaminated the electrical connections, the engine's reliability was compromised, creating a significant risk of sudden engine stalling while driving in traffic or at high speeds. Fire hazard: the intrusion of diesel fuel—a combustible fluid—directly into the electrical wiring harness and the dde created a clear fire hazard. Fuel near active electrical components poses a serious safety risk. Inaccurate temperature readings: the egt (exhaust gas temperature) sensor received incorrect readings due to the dde/wiring issue, leading to potential engine damage due to excessively high exhaust temperatures. The problem has been confirmed by BMW of loveland. The service director and their technical team identified the root cause in less than one day and confirmed it requires the replacement of the sensor, harness, and dde. This was also validated by an internal BMW technical support case (tsara). Gebhardt BMW failed to diagnose the issue correctly over three prior attempts starting in June 2023 through Aug 2025. Prior symptoms appeared over a period of months and included: intermittent check engine light/mil. Multiple, confusing diagnostic fault codes (related to air mass, charging pressure, and dpf efficiency). Increased frequency of dpf regeneration intervals.

On may 26, 2025, after I arrived home and parked my 2025 BMW X3, the vehicle caught fire approximately 30 minutes later. The fire started due to a known recall issue (NHTSA recall no. 25v202) related to the electrical/starter-generator connection, which can cause overheating and fire. I contacted BMW multiple times before the incident — on April 19, may 9, and may 25 — requesting help to fix the open recall, but they failed to take action. The fire was sudden and violent, putting my life and property at risk. Firefighters and police responded; case number: 25/200048976. I filed a claim with progressive insurance and have photos and documentation available.

Vehicle: 2025 BMW X3 complaint description: I am reporting a serious safety defect involving sudden unintended acceleration, braking abnormalities, steering looseness, and electronic system failures. Within days of purchase, the vehicle began experiencing infotainment system freezing and electronic malfunctions. Over time, steering looseness and abnormal brake behavior developed. These issues were reported to authorized BMW service centers but were not corrected or properly documented. On may 17, 2025, while the vehicle was stationary and in park, it suddenly accelerated without driver input after a passenger exited the vehicle. I attempted to brake, but the vehicle continued forward and collided with a stone structure, causing injury. BMW later claimed driver error based on post-collision data but ignored extensive pre-collision defect evidence. The vehicle was returned from repairs and continues to exhibit malfunctions. I believe this vehicle presents a serious safety risk to drivers, passengers, and the public.

Backup camera failure , missing rearview image when car gear is shifted to r, increasing the risk of crash and injury. When reversing the backup camera does not display any image/video feed on the screen, only the collision warning system is displayed.
