Each component in detail
What the reports in each category say, in the owners' own words
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
The car has a plastic part in the oil housing component that cracks under heat usually between 50000 and 70000 miles causing a major loss of coolant onto highway and disables the engine
The contact owns a 2019 BMW 430I. The contact stated that there was a coolant leak. The contact stated that the engine overheated and the vehicle stalled while driving. The message "Engine Overheating - Stop Vehicle Immediately" was displayed. The vehicle was towed to the local dealer, where it was diagnosed, and it was determined that the coolant housing needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was taken back to the local dealer, where it was determined that the coolant water pump needed to be replaced. The vehicle was repaired, but the failure persisted. The vehicle was taken to the same local dealer, where it was diagnosed, and it was determined that there was coolant leaking from the oil housing. The vehicle was not repaired. The manufacturer was contacted, a complaint was filed, and the contact was referred to the NHTSA Hotline. The failure mileage was approximately 116,758.
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.

I am reporting a potential safety defect involving the seatbelt, airbag, and occupant detection system in my 2019 BMW 430i. At the time of purchase, the vehicle’s software had not been updated since 2018. Because the software was so outdated, multiple safety-related fault codes did not appear during the dealer’s pre-sale inspection or during initial diagnostic checks. During a later service appointment, the dealership informed me that they were unable to perform accurate diagnostics because the software was old and could interfere with sensor readings. After I paid for the software update, several safety-related codes appeared, including faults connected to the seatbelt/occupant classification system. None of these safety defects were disclosed to me prior to the sale. This raises concern that the vehicle had an existing safety defect at the time of sale, but the outdated software prevented the detection and reporting of these faults. If other vehicles are being sold without current software, this may result in safety-critical issues being hidden from consumers and inspectors. A malfunctioning seatbelt or occupant detection system significantly increases injury risk in a crash. If outdated vehicle software suppresses or fails to display safety-critical faults, consumers may unknowingly be operating unsafe vehicles.
The airbags did not deploy upon impact from head on collision into another vehicle. The vehicle was towed and the other vehicle’s airbags did deploy that was involved in the collision. There was a police report filed & the insurance company has picked up the vehicle for them to complete an inspection & evaluation.

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
The car has a plastic part in the oil housing component that cracks under heat usually between 50000 and 70000 miles causing a major loss of coolant onto highway and disables the engine
On Aednesday April 12th, I was driving on a busy road and the car died. There was no safe place for me to pull off which had cars swerving to miss me. There was no indication of coolant level low. The car just died. After extensive research, I found out this car was part of a service action that was never performed because I wasn’t notified of it. This is very dangerous to anyone who owns a 2019 BMW 430i and will cause bodily harm or death if not recalled.

Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
The contact owns a 2019 BMW 430I. The contact stated that while driving approximately 55 MPH and switching lanes, there was a loud explosion. The contact was unable to determine the cause of the sound. The contact pulled over to the side of the road to inspect the tires and discovered that the sunroof had shattered upward. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 131,992.
MY SUNROOF EXPLODED WHILE DRIVING. THERE WERE NO OTHER VEHICLES ON THE ROADWAY. THE EXPLOSION WAS VIOLENT AND LOUD. LUCKILY THE VIOLENT EXPLOSION DIDN'T CAUSE ME TO CRASH. BITS OF GLASS ARE STILL STUCK IN MY SKIN. I CAN FEEL THE GLASS BUT I CAN'T SEE IT.

Rear window does not work. This car collects water from the windows which pools inside the window panel. Eventually, the pooled water damages the window motor and window regulator. Once the window stops working, the convertible top no longer works. This issue is reported all over youtube and google searches. The worse part is that to fix this, mechanics have to manually bring down the convertible top. Examples: [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2019 BMW 430I. The contact stated that while driving at an undisclosed speed, the "Coolant Low" message was displayed, prompting the contact to add coolant to the coolant reservoir. The vehicle returned to normal functionality, but the failure became a regular occurrence. The low coolant warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 24V608000 (Engine and Engine Cooling, Electrical System), but the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was 99,000.

My fiancé was driving my vehicle and hit a tree. The air bag deployed and she has shrapnel cuts on her face. The surgeon stated that she should not have had that injury on the face like she did.

SEAT OCCUPANCY SENSOR IS SENSING A FAULT. IT SAYS IT IS NOT WORKING AND THE AIRBAG IS NOT ON. THE DEALER IS RELUCTANT TO REPAIR IT, BECAUSE IT'S EXPENSIVE. IT'S UCLEAT IF THE AIRBAG WILL WORK.

From owner reports, verbatim
I purchased my vehicle October2023. May 23,2024, at 1:34 pm, my vehicle broke down due to a message on my dashboard stating “Drivetrain malfunction”. I was on the highway with no use of my gas pedal, which resulted in me rolling back all while being 5 months pregnant. June 18,2024, at 3:04pm ,my vehicle broke down again due to the same message that previously popped up “Drivetrain malfunction”. I was also on the highway with no use of my gas pedal all while pregnant. July 18,2024, at 12:25 midnight, my vehicle broke down again due to the previous problem “Drivetrain malfunction” by the airport with no use of my gas pedal all while 6 months pregnant. Each time I my vehicle malfunction I almost got hit by other vehicles because I had no use of my gas pedals to get out of the way. There were no warning signs at all. When the message pops up on my dashboard the gas pedal completely becomes inoperable. This vehicle has put me and my soon to be baby in harms way multiple times. The dealership has had 3 times to fix the problem and still fail to do so. Having their opportunity to fix it three times just to tell me it’s because it doesn’t have gas in it when it did has put my in a situation where I’m constantly worried about it braking down again putting me and my unborn child in danger AGAIN, to where I am financing a car I can not use. Not including the 2 times I had to pay to get it towed from the airport because the police told me I couldn’t leave it there.

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.
