What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2019 BMW 330I, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
Vehicle shudders under acceleration no warning lights or errors . Changed transfer case oil and same problem continues. No recall from manufacturer for issu
I am reporting a premature failure of two critical engine components: the Heat Management Module (Coolant Pump/Thermostat assembly) and the Oil Filter Housing. Despite the vehicle's low mileage (40,000 miles), the Heat Management Module began leaking coolant, posing a significant risk of engine overheating and sudden loss of power while driving. Simultaneously, the Oil Filter Housing has developed a leak, allowing oil to seep onto the engine block and potentially onto the serpentine belt. Both failures represent a safety hazard: Coolant Leak: Risk of thermal engine damage and being stranded in traffic due to overheating. Oil Leak: Risk of oil contacting hot exhaust components (fire hazard) or causing the serpentine belt to slip/fail, resulting in a sudden loss of power steering and charging systems. These components appear to have failed due to manufacturing or material defects rather than standard wear and tear for a vehicle of this age and mileage

Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
The contact owns a 2019 BMW 330i. The contact stated that while driving at 60 MPH on a three-lane highway, traveling in the exit lane, and using the hands-free calling system to speak with his wife, the vehicle crashed into an unknown metal object in the roadway, which tore the undercarriage. The driver-side air bag exploded without warning, resulting in him sustaining a concussion, and the vehicle came to a stop. The emergency call system failed to activate. His wife was able to contact 911, who was delayed in locating the incident site. The fire department, ambulance, and police department were on the scene. The contact was treated at the scene by the ambulance. The contact went to a walk-in clinic the next day, where medical attention was provided. There was no reported fire or police report filed due to the lack of identification of any damage. The vehicle was towed to the local dealer, who determined there was damage to the undercarriage. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had written a letter to send to the manufacturer. The failure mileage was approximately 51,443.
Seat restraint malfunction that prevents the air bag from working properly. Dealer is aware of this problem but has not been able to correct it.

BMW ADVERTISES AS A SAFETY FEATURE AN EMERGENCY BRAKE ASSIST SYSTEM THAT "WARNS ABOUT THE RISK OF COLLISION AND, WHERE APPROPRIATE, BRINGS THE VEHICLE TO A COMPLETE STOP BEFORE IT RESULTS IN A CRASH WITH AN OBSTRUCTION, A PERSON OR ANOTHER VEHICLE" (HTTPS://WWW.BMW.COM/EN/INNOVATION/THE-MAIN-DRIVER-ASSISTANCE-SYSTEMS.HTML#PWJT-EMERGENCY-BRAKE-ASSIST) MY WIFE WAS DRIVING AT ABOUT 10-15 MPH AND THERE WAS ANOTHER CAR IN FRONT. SHE WAS DISTRACTED BY A CRYING BABY AND TOOK HER EYES OFF THE ROAD AND COLLIDED WITH THE FRONT CAR. THE BMW SYSTEM FAILED TO TAKE ACTION TO BRAKE TO MINIMIZE OR AVOID THE COLLISION. THIS WAS CONFIRMED WHEN BMW QUERIED THE SYSTEM, THAT NO BRAKING ASSIST WAS APPLIED IN THE INCIDENT. THIS "SAFETY" FEATURE WAS ADVERTISED BY BMW AND WE PAID A PREMIUM FOR THIS FEATURE AND IN FACT DECIDED TO LEASE THIS CAR BASED ON THIS FALSE PREMISE/ ADVERTISEMENT. IN THIS INSTANCE, THE ACCIDENT OCCURRED DURING DAYLIGHT ON A CITY STREET, WITH SUNNY WEATHER, WITH AN OBJECT AT A STANDSTILL IN FRONT OF MY CAR. *TR

Other / unspecified
Reports whose component NHTSA recorded as unknown, or that do not map to one of the categories above.
From owner reports, verbatim
ONE OF THE FOUR ORIGINAL TIRES, PIRELLI CINTURATO P7 ALL SEASON 225 /45 R18 95H XL BSW BM RF, HAD BLOWOUT ON THE INTERNAL WALL WITHIN ONLY 15,000 MILES. THE TIRE BLEW OUT AT REST. NO NOTIFICATION OF FAILURE ON THE MONITORING SYSTEM. NO DAMAGE TO THE TIRE RIM. UNLESS IT STRUCK A POTHOLE NOT FELT WELL DRIVING. THE IS THE SECOND TIRE TO DO THIS ON THE VEHICLE IN THE FIRST YEAR OF OWNERSHIP. SEEMS LIKE THE TIRES FAIL ON THEIR OWN.
THE THREE OF THE FOUR ORIGINAL TIRES, PIRELLI CINTURATO P7 ALL SEASON 225 /45 R18 95H XL BSW BM RF, HAVE HAD BLOWOUTS ON THE INTERNAL WALL WITHIN ONE MONTH AND ONLY 13,000 MILES. I NOTICED THERE IS A RECALL ON THE PIRELLI 19" TIRES. I BELIEVE THIS HAS TO BE A MANUFACTURER DEFECT. THERE WAS NO TRAUMA THAT CAUSED THE BLOWOUTS AND THEY ALL OCCURRED SPONTANEOUSLY.

My 2019 BMW 330i has a recurring cooling system defect, including coolant leaks, heater inoperative, and risk of engine overheating. The defect began while the vehicle was under warranty and was repaired by BMW, but it recurred. BMW later instructed me not to drive the vehicle due to safety concerns, yet declined responsibility and transportation. The vehicle remains unsafe to operate.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
