When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2018 BMW 330E
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants.

Pedestrian alert sounds
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States.

Unknown - I returned from a work related trip out of the country, started my vehicle and coolant was pouring everywhere. BMW stated there's a recall coming out but have not seen one since the repair in April which was over a thousand USD.

STEERING
In May 2021 I purchased a 2018 Certified Pre-owned BMW 330e Plug-in Hybrid with 20K miles from the BMW dealership at Glendale, CA. My car is under original manufacture warranty to this day but I also have paid for an extra warranty and maintenance program. On December 26th, 2021, as I was driving back from Las Vegas on highway 15, about 40 miles into the trip, my car dash displayed an error message "Charging Malfunction" immediately after this error, the entire car systems INCLUDING BREAKS AND STEERING WHEEL! stopped working. I lost control of my car and my car went towards the right side of the road where there's no asphalt and it's all dirt and pebbles. car was finally stopped with the help of manual handbrake but I was terrified and I felt lucky to survive the incident. BMW roadside assistance towed my car to the BMW dealership in Las Vegas since it's the closes dealer. they said they don't have any loaner car and I should get rentals and they will pay for it at the end since it's part of my warranty is to provide "Transportation" while the car is at the shop. they also said once my car is fixed, they will "reunite" my car in Los Angeles. 2 days after, the dealership declined any repair due to a leak on the radiator and I was told my car was "Overheated". Although my car had no indication of overheating ever or at the time of the incident. The picture I took from the error also shows the temperature of my car which is normal. See picture. I can't wrap my head around losing break and steering wheel without any prior error or indication of overheated car. BMW is can't explain why and neither can my insurance after reviewing my car's computer logs, how could I trust driving this car again if break and steering wheel could fail without any prior indication of overheating or low coolant or ANY error? A car that is still under manufacturer warranty with only 31K miles! who will be responsible if I crash and get injured or die if this happens next time?
