2020 BMW X3 Complaints

The heated seat element had a runway incident that caused the seat to smoke and burn a hole through multiple layers and ultimately damaging the airbag sensor mat disabling the passenger airbag system

It has come to my attention that liquid from the Positive Crankcase Ventilation (PCV) system may leak onto the water pump electrical connector. This condition can lead to an electrical short circuit and, in rare cases, may increase the risk of a vehicle fire. This issue presents a serious safety concern for vehicle owners and others on the road. A failure of this nature, especially one that carries a fire risk, warrants immediate review and corrective action. I respectfully request that NHTSA investigate this matter and determine whether a safety recall is necessary to address this defect. The dealership noticed the leak beginning at the weep hole of the waterpump. No incident occurred this is for preventive measures and review for recall and reimbursement

Due to a TSB (SIB 65 12 22) wherein the roof antennae leaks water and causes a short in the telemetry module, the car does not have pedestrian warning, navigation or backup camera / cross traffic warning. The car is drivable, but compromised from a safety perspective.

The contact owns a 2020 BMW X3. The contact received notification of NHTSA Campaign Number: 25V636000 (Electrical System); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was contacted and confirmed that the part to do the recall repair was not available. The manufacturer was not made aware of the issue. The contact had not experienced a failure.

The contact owns a 2020 BMW X3. The contact stated that upon starting the vehicle, there was an abnormal thumping sound coming from the vehicle. There was no warning light illuminated. The contact later received notification of NHTSA Campaign Number: 25V636000 (Electrical System); however, the part to do the recall repair was not yet available. The vehicle was taken to a local dealer, and the contact was informed to leave the vehicle at the dealer overnight. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The vehicle was not repaired. The failure mileage was approximately 60,000.

I am submitting a formal safety complaint regarding a defect in my 2020 BMW X3 that has resulted in the failure of a critical emergency safety system. The vehicle displayed an error message indicating an “Emergency Call System Malfunction.” I brought the vehicle to BMW of Murrieta on March 30, 2026, for diagnosis and repair. Upon inspection, the service center determined that the Telematic Control Unit (TCU) had sustained water damage. This damage was attributed to water intrusion originating from the vehicle’s shark fin antenna. This is a known issue documented by BMW in internal Service Information Bulletin SIB 65 12 22 (dated October 5, 2022). Despite acknowledgment of this known defect, BMW declined to cover the repair costs for both the antenna-related water intrusion and the resulting damage to the TCU. This failure presents a significant safety hazard. The emergency call system is designed to automatically notify emergency services in the event of a collision. With this system inoperable, occupants may be unable to receive timely emergency assistance, increasing the risk of serious injury or death. Given that BMW is aware of this defect and its potential to disable a critical safety feature, I believe this issue warrants further investigation and should be considered for a mandatory safety recall.

This recall was in September 2025, and for a starter issue that could cause a fire. Despite the urgency of this recall, it's now six months later, and I am still getting a response from BMW "Remedy Not available". So, in the meantime BMW advises to keep the car outside in the hot Florida sun so it doesn't burn the house down. This is a totally unacceptable situation, and I would appreciate the NHTSA following up with BMW regarding why the delay. It appears to me that BMW is dragging their feet on correcting this serious issue.

I am reporting a safety concern involving BMW vehicles equipped with the B58 Technical Update (B58TU) engine, commonly found in model years 2019–2021. These vehicles utilize a variable-displacement engine oil pump containing an internal thermoplastic adjusting component responsible for regulating oil pressure. Field failures are increasingly being reported in which this internal component fractures, resulting in sudden loss or instability of engine oil pressure. The failure frequently occurs during cold-start operation in low ambient temperatures. When the component fails, oil pressure regulation becomes erratic or is lost entirely. In many cases, drivers receive little or no actionable warning prior to engine damage or vehicle disablement. Reported precursor symptoms include inability to electronically measure engine oil level, abnormal oil pressure behavior, or sudden drivetrain malfunction warnings. Failures may rapidly progress to engine shutdown or severe mechanical damage caused by oil starvation. Loss of lubrication can cause the vehicle to become disabled without warning while driving or shortly after startup. This creates a safety hazard, particularly when vehicles become immobilized in active traffic or during winter conditions the cold is when they fail the most, where occupants may be exposed to freezing temperatures while awaiting assistance. Replacement of the oil pump requires extensive disassembly of the vehicle and repairs commonly exceed $6,000–$8,000 for just the pump, assuming the motor is unharmed. Owners are currently unable to determine whether their vehicles contain the original thermoplastic oil pump design or a later revised version utilizing metal internal components, as VIN-based parts information now identifies updated components in the car even when no replacement has occurred and the old components are actually in the car. Also, BMW has actively removed the plastic part number out of all dealer networks as well. They are aware.

The contact owns a 2020 BMW X3. The contact stated that while her son was using the rear passenger's side seat belt, the contact became aware that the seat belt was fraying. The vehicle was taken to the dealer and was provided an estimate for the seat belt replacement. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 49,000.

Component Failed: Engine starter relay and starter motor assembly. The vehicle stalled in traffic and ignited upon a restart attempt. The vehicle is a total loss, currently held by [Insurance Co] at [Location/Lot #], and is available for inspection. Safety Risk: The driver’s life was at immediate risk. The vehicle stalled in active traffic, creating a collision hazard, followed by a rapid, uncontrollable engine fire. The driver suffered smoke inhalation and severe trauma while escaping. A delayed exit would have been fatal. Confirmed by Dealer: The failure mirrors the defect pattern in Recall 25V-636 (Starter Relay Corrosion). While the fire prevents reproduction, the vehicle had a consistent service history with no prior electrical issues. Inspected By: The vehicle was inspected by [Insurance Co] and declared a total loss. [Optional: The Fire Dept. responded under Report #[Number]]. BMW was formally notified via demand letter on [Date]. Warning Lamps/Symptoms: No prior warnings. The failure was acute. A "Drivetrain Malfunction" message appeared seconds before the stall. Smoke and flames appeared immediately upon the attempted restart.
