2019 BMW X3 Problems

Our 2019 BMW X3 M40i shows "EMERGENCY CALL SYSTEM MALFUNCTION" which means the "SOS" system, which is crucial for post-collision response, fails. Erhardt BMW in Bloomfield Hills, Michigan confirmed water leakage due to defective sealing around the roof-mounted shark fin antenna damaged the Telematics Control Box (TCB) and now requires replacement. The estimated cost is $3,600. Some quick research revealed this to be a repeated problem with my vehicle. BMW has acknowledged it as a defect in 2017-2023 model year BMW M440i, M550i, X1, X3, X4, X5, X6, X7, 330, 340i and 750i vehicles and fix it at no cost, but only for citizens of [XXX] , as reported by [XXX] of [XXX] .

Main dashboard display is partially blocked by a message stating “emergency call system malfunction.” Apparently the roof mounted antenna’s seal fails and allows water into the electronics for the emergency call system. Upon failure, it also stops the Bluetooth microphone for the cell phone to stop working. The dealer quoted the repair at $3,200. Judging from a google search, this is a common problem among this generation of BMW vehicles.

I bought my 2019 BMW X3 late 2025 before Christmas. The Carfax was fine and there were no open recalls on the vehicle. The vehicle had been serviced regularly at BMW facilities. Our family mechanic looked at the vehicle before I bought it and performed some basic diagnostics. The vehicle appeared fine. There were no error codes and all of the fluids were topped off. I don't know if the issues with the coolant were there before I purchased the vehicle or if they happened afterwards. There were no warning lights and everything looked good. This car is garage kept and is used a couple of times a week. I did my research on the internet and took my car in for an oil change at a highly-rated independent auto repair facility that specializes in European vehicles and are famous for providing dealership-level expertise, ASE-certified with factory trained technicians from Germany. On March 5th, 2026, when I went to pick up my car, they told me the bad news that is a well known manufacturer defect within the industry regarding these vehicles. They used plastic components in the engine compartment and in the cooling system, which makes the vehicles malfunction. From their report, with pictures, they state the following repairs need to be made, "During the vehicle inspection noticed active coolant leaks are present from multiple locations. The radiator plastic tank actively leaking coolant. The water pump change over valve leaking coolant. The turbocharger coolant line has a coolant crud build up . Oil filter housing and coolant flange on the cylinder block are discolored. For proper cooling system repair recommend complete update of the cooling system. Both balance shaft end caps leaking oil. Recommend replacement during cooling system update." They quoted me $8,914.86 for this repair. That's over HALF the value of the vehicle. They said the entire system needs to be replaced because ALL of the plastic parts in Florida's hot sun will fail. Sudden coolant failures in FL = DEATH.

I am submitting this complaint regarding a serious mechanical and safety issue involving my 2019 BMW X3. On or around January 21, 2024, while driving from my home, a warning signal suddenly appeared on my dashboard related to the vehicle’s cooling system/engine. Due to safety concerns, I pulled into a nearby Wawa parking lot, which was the safest available place to stop at the time. I turned the vehicle off and waited approximately 15 minutes before carefully driving the vehicle back home. After inspection and diagnosis, I was informed that the vehicle required extensive repairs, including an engine replacement and cooling system repairs. At the time the coolant warning appeared, the replacement engine reportedly had approximately 59 miles on it. I believe a sudden engine or cooling system malfunction while operating a vehicle presents a serious safety concern for drivers, passengers, and others on the roadway. In addition, I experienced issues involving the shark fin antenna on the vehicle, which I understand may be connected to broader complaints involving BMW vehicles. I am requesting that NHTSA review this matter to determine whether these issues may indicate a broader defect or safety-related concern affecting other consumers. I am willing to provide supporting documentation including repair invoices, dealership records, photographs, and any additional information requested. Thank you for your attention to this matter and for your commitment to vehicle safety.

While driving our BMW 2019 X3 on the highway, other drivers honked to get my attention that our vehicle's rear hatch was partially open. When we came to a stop light, I had my son riding in the passenger seat press the hatch button on the key fob to close the hatch. Instead this fully opened the back hatch. We continued pressing the fob button in an attempt to get the hatch to close without having to exit the vehicle. Rather than exit the vechicle in the middle of the roadway, we drove about 50 yards until we could pull over safely. A motorcyclist had been following us, and came up behind and communicated that he wanted to press the button to close the hatch. After I gave my consent, he pressed the close button and the hatch closed and latched. My husband has previously had incidents where after parking the BMW, he finds the back hatch open. He's also researched online this is apparently an issue. Reference: [XXX] NHTSA claim XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2019 BMW X3 with operable sunroof. Significant leakage occurred in front and rear of car risking electrical failure and therefore accident. Dealer denies that this is a problem and Bmw takes no responsibility for what is a hidden defect of the drainage system for the sunroof. Hundreds of individuals have the same exact problem. Hundreds are automatically denied any assistance or responsibility by dealer or manufacture. In a prior claim, it appears that Bmw lost and was found guilty of concealment of a manufacturers defect and was instructed to pay $500 million to plaintiff. Examination of law firms indicate that this significant problem affecting hundreds perhaps thousands of Bmw x-3 has not been registered as a significant complaint, notwithstanding the fact that they have already been in court and been found guilty. Please contact me 804-241-2773 Cell. Or [email protected]. Examination of owner handbook produced by Bmw informs owner that rails and drains for sunroof must be cleaned. But they indicate that problems with this issue are not covered by the warranty. This needs to be verified. Anecdotal Reports indicate that hundreds of complaints have been received. Bmw is denying any responsibility. Conversation with attorneys indicate this is a habitual problem with Bmw. In this case, it’s a manufacturers defect, on disclosed, causes damage, all problems are denied by manufacturer. Consider this a formal submission of a complaint and a violation of variety of rules and laws covering local, state, and federal jurisdiction Richard grossberg 405 Westham Parkway, Richmond, VA 23229

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)

Rear caliper locking up when in reverse. Knocking noise and crunching sound.

PHANTOM BRAKING ISSUE - Twice now while driving 50-55 MPH on clear roads the brakes slammed on without cause - COMPLETE SHUTDOWN - While going thru a restaurant drive thru - the car completely shut down and would not move forward - I had to back up in order to get out of drive thru - thankfully no one was behind me.

My 2019 BMW X3 equipped with a B46 engine developed a significant coolant leak at approximately 80,000 miles. The vehicle displayed a low coolant warning, and coolant was visibly leaking underneath the vehicle. Around the same time, I began noticing excessive white exhaust/steam during cold starts and, for the first time since owning the vehicle, had to add engine oil between scheduled oil changes. The vehicle is currently undergoing inspection by an independent repair facility. Preliminary findings indicate concerns involving premature failure of critical plastic cooling system and/or oil filter housing components. Based on my research, these failures appear consistent with widespread complaints involving BMW B46/B48 engine cooling system and oil filter housing defects. I am concerned this defect could lead to sudden coolant loss, overheating, engine failure, or unsafe driving conditions. Prior to the coolant warning appearing, there were no significant alerts indicating a major or imminent cooling system failure. The apparent failure of critical plastic engine cooling components under normal driving conditions raises serious concerns regarding the durability and safety of these parts. I have photographs documenting the coolant leak, as well as detailed notes and diagnostic information from the repair facility, available upon request. The vehicle is available for inspection.

Reporting a failure of the engine cooling system on my 2019 BMW X3 that developed over time despite repeated repair attempts and ultimately resulted in complete engine failure. Over the past year, the vehicle has experienced ongoing coolant loss and overheating warnings despite multiple coolant-related repairs. When the problem continued, I brought the vehicle to a BMW dealership, where the service department determined that the engine had suffered internal damage consistent with overheating and advised that a full engine replacement was required. These issues occurred during normal driving and created unsafe conditions, including the risk of sudden loss of power or breakdown in traffic. Based on my experience and the repeated nature of the failures despite proper maintenance, it appears that coolant and overheating issues may be persistent in this vehicle model rather than isolated to a single component, and I am concerned that other owners may be experiencing similar safety-related defects. A investigation into this is warranted.

My lights turn on and off while the vehicle is turned off until I lock the car.

Headlights cycle on and off. Does this frequently. Checked on BMW site Bimmerpost and other people have had the same problem. Google 2019 BMW x3 headlights tuning off and on after shut down.

The contact owns a 2019 BMW X3. The contact stated while driving approximately 46 MPH, there was an abnormal sound coming from the roof of the vehicle. The following day the contact discovered that the glass sunroof had exploded and there was a hole in the sunroof glass. The manufacturer and local dealer were notified of the failure. The cause of the failure was not yet determined. The contact stated that during the failure, the temperature was extremely cold and the heater inside the cabin of the vehicle was activated. The vehicle was not repaired. The failure mileage was 30,000.

1- Passenger Restraint System Malfunction error codes- related to wiring or front passenger seat- long timeframe and expense to diagnose 2- Engine mounts broken Oct 2023 and again Aug 2025- known issue by BMW service- high repair cost & repeat failure 3- Front crash assist will brake for shadows caused by trees or adjacent trucks and has nearly caused accidents

The contact owns a 2019 BMW X3. The contact stated that while driving at an undisclosed speed while the front passenger’s side seat was being occupied, the message "Front Passenger’s Restraint System Malfunction" was displayed. The vehicle was taken to the dealer, where it was diagnosed and determined that the front passenger’s side seat mat detection sensor had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 68,500.

I'm reporting a safety issue with BMW vehicles equipped with the B58 engine, primarily 2019-2021 models. These vehicles have an oil pump with an internal plastic component that regulates oil pressure, and this part is fracturing in the field, causing sudden loss of oil pressure. The failure typically occurs during cold starts in low temperatures. When it fails, oil pressure becomes erratic or is lost entirely, often with little to no warning before engine damage or vehicle disablement. Warning signs, when present, include inability to measure oil level electronically, abnormal oil pressure, or sudden drive train malfunction warnings. These can rapidly progress to engine shutdown or severe damage from oil starvation. This creates a dangerous situation because the vehicle can become disabled without warning while driving or after startup. This is especially hazardous when cars become immobilized in traffic or during winter conditions when failures occur most frequently, leaving occupants exposed to freezing temperatures while awaiting assistance. Pump replacement requires extensive disassembly and commonly costs $6,000-$8,000, assuming no engine damage. A critical concern: owners cannot determine if their vehicle has the original plastic pump or the later metal revision. BMW's VIN-based parts lookup now shows updated components even when original plastic parts remain installed, and BMW has removed the original plastic part number from dealer networks entirely. Failures are reported across multiple production years, and the scope of affected vehicles remains unclear. Because this condition causes sudden vehicle disablement without adequate warning, especially in cold weather, I believe this warrants investigation as a potential safety-related defect.

On returning to my locked vehicle that had been in the parking ramp for 3 days, I started the car and the display message indicated that my vehicle was completely out of gas and the oil was very low. The vehicle had nearly a full tank of gas when it was parked. The vehicle was towed to the dealership who assessed the vehicle. The service department indicated that the vehicle likely did not sound like it was running because of the idle feature, and as such, I may have thought I shut off the car, but that eventually the idle feature turned off, and the vehicle ran while it was locked until it was out of gas. The service man who sent me a video of my vehicle and described what happened, also showed me another BMW SUV in the hoist next to my vehicle and indicated that same vehicle had the same thing happen as well. BMW replaced the programing/encoding control units software that was original to the vehicle. They indicated that this would improve overall function of the vehicle. The cost of this replacement was $371. This sounds like a design flaw. How can a locked vehicle start back up after a period of time, by itself with no vehicle fob in the vicinity, and run for hours until it is out of gas and the oil is low?

FIRST PROBLEM IS THAT ONE THREE SEPARATE OCCASSIONS MY REAR HATCH/TAILGATE HAS OPENED ON ITS OWN WHILE PARKED. EACH OF THE THREE TIMES THE CAR WAS PARKED IN THE GARAGE AND HAS HIT MY GARAGE DOOR CAUSING DAMAGE. WHILE IN THE GARAGE, MY KEYS WERE INSIDE THE HOUSE AND NO BUTTONS WERE PUSHED ON THE KEY FOB. I HAVE COMPLAINED TO THE DEALER ABOUT THIS ISSUE TWICE NOW AND HAVE NOT HAD SUCCESS IN SOLVING THE ISSUE. SECOND PROBLEM IS THAT THE SEAT VENTILATION ON THE PASSENGER SEAT HAS FAILED THREE TIMES. EACH TIME THE FANS WITHIN THE SEAT THAT ACTIVATE TO PUSH AIR THROUGH THE VENTS SOUND LIKE THEY ARE TEARING THROUGH THE SEAT. EACH TIME THE DEALER HAS REPAIRED THE ISSUE, ONLY FOR IT TO RETURN AGAIN. THE CAR IS GOING TO THE DEALER ONCE AGAIN AFTER I ASKED FOR THEM TO ESCALATE THIS ISSUE. I HAVE NOT YET HAD THE CAR ONE YEAR. MY PURCHASE DATE WAS IN SEPTEMBER 2018.

THE TAILGATE OPENED BY ITSELF WHILE I WAS DRIVING ON THE HIGHWAY. I HAD A SHORT LOCAL DRIVING BEFORE ENTERING THE HIGHWAY. ABOUT 5 MINS IN THE HIGHWAY AT AROUND 60 MPH, THE TAILGATE OPENED BY ITSELF. THE CAR FELT VERY NOISY AND HARD TO CONTROL (I WAS ON A WINDY HIGHWAY). I HAD TO EXIST THE HIGHWAY, STOP ON A LOCAL STREET, AND CLOSE THE TRUNK. THE SAME RANDOM OPENING ALSO HAPPENED ONCE IN MY GARAGE WHILE THE CAR WAS PARKED AND LOCKED, A WEEK AGO. WITH TWO RANDOM OPENING HAPPENED IN ONE WEEK, I AM AFRAID OF DRIVING IT. YOU NEVER KNOW WHEN THE TAILGATE WILL SUDDENLY OPEN AGAIN.

The contact owns a 2019 BMW X3. The contact stated while driving at an undisclosed speed, the seat belt warning light illuminated. After restarting the vehicle, the vehicle seemed to return to normal functionality however, the failure had become a regular occurrence. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The failure mileage was 36,000.

While driving, an error message appeared on the car screen that said: Passenger restraint system malfunction: Contact BMW Carefully drive to the closest service center. Passenger restraint system is limited. Increased risk of injury in case of a collision. Continue wearing safety belt. 1) What component or system failed or malfunctioned, and is it available for inspection upon request? Passenger restraint system 2) How was your safety or the safety of others put at risk? Increased risk of injury in case of collision 3) Has the problem been reproduced or confirmed by a dealer or independent service center? The dealer ran a diagnostic and no fault was found. They tried to claim that there was water on the seat because an umbrella was on the seat. It was not raining before or during the time the message appeared. The umbrella has not been used for quite some time and was not wet. 4) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Just the dealer. 5) Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None. This appears to be a random deactivation of the passenger restraint system.

I was driving in my bmw x3 going about 35 miles an hour and hit a small pothole next thing I know is I got a flat tire when I pulled over the perch plate on the strut had slipped down and hit the tire causing it to blow out and now I'm stuck having to replace the entire strut assembly

I am reporting a manufacturing defect on BMW vehicles, specifically the 2019 BMW X3 with fewer than 40k miles. According to a vehicle inspection conducted at a BMW dealership on Saturday November 22, 2025, the motor mounts are collapsed. Potential risks are excessive engine vibrations that could cause loss of control while driving, to engine components to fall off the ground while driving. It’s dubious that BMW dealers “discovered “ this issue after the vehicle warranty expired. I request that the matter be investigated and order the manufacturer to extend coverage to a minimum of 120k miles or 6 years from date of service. Please investigate before it’s too late. Thank you.

Subject: Rear Differential Mount Failure and Driveshaft Breakage — Sudden Loss of Vehicle Control at Highway Speed Complaint Summary: While driving at highway speed, I experienced a sudden and extremely loud bang from the rear of the vehicle. Immediately afterward, I lost complete control of the rear end, accompanied by violent clanking and grinding noises from the driveline area. The gearbox then stalled, leaving the vehicle disabled in the middle of the highway. Upon inspection, it was determined that a rear differential mounting bolt had sheared, causing the differential to shift violently out of position. This sudden movement resulted in the driveshaft breaking, which further destabilized the vehicle and led to a severe and immediate loss of control. This failure occurred without warning and created an extremely dangerous situation. The sudden loss of drivetrain integrity at highway speed placed both myself and nearby motorists at serious risk of a crash. A component as critical as a differential mount or driveshaft should not fail under normal operating conditions. This incident strongly indicates a serious design or manufacturing defect affecting the vehicle’s powertrain and structural safety. Requested Action: I urge the NHTSA to investigate rear differential mounting and driveshaft failures on this vehicle model. Such failures can lead to catastrophic loss of control, and immediate attention is necessary to prevent future incidents and ensure driver safety.
