BMW issued an extended warranty of 15 years/150k for a pressure control valve (PCV) failure for certain years/models that included my vehicle. While driving, the PCV failed causing a loud high pitch noise and white smoke billowing from my exhaust. Such an immediate failure while driving of this PCV valve should have been subject to a recall given the sudden and unexpected failure. I travel a lot for work and if this would have happened while travelling and out of town, it would have been a more serious incident in addition to the inconvenience. After have the PCV replaced, my vehicle's RPM's would drop at startup when put in reverse and/or back in drive, causing the vehicle to stall and jerk forward. This problem was never an issue prior to the PCV failure. Since the replacement my car has stalled numerous times placing myself in danger of having to hurriedly restart my car and "gun" the accelerator to prevent another stall. Because of this issue which I correlate directly to the PCV replacement, I am now being told the software needed to be updated. However, instead of being considered part of the PCV issue, they are charging 200 dollars to remedy. I'm sure others have reported issues similar to mine. Bottom line is that this whole issue should be subject to a recall and covered by BMW before someone's car stalls resulting in serious damages and injuries to vehicles and persons.

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.

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.

Car stalled because of coolant vent line in cylinder head Faulty coolant line like other models. I was lucky enough to get out of traffic without an accident. This car had to be flatbeded to dealership to repair their “service advisory” which I was never notified of. My papers from dealership says BMW recall and they are now refusing payment for tow!! This faulty part could cause someone to be killed!!! They need to be held accountable for tow because of a faulty part that could be deadly

"Passenger restraint system: Malfunction" alert came up on the display screen and then quickly disappeared several times. BMW dealer said the seat belt/airbags would not operate correctly in the event of a crash. BMW dealer said it was not related to the 2 recalls issued in 2021 and 2022 on this car for coolant or telematics (which BMW had not notified us about yet or fixed during service appts in 2021 or 2022). From a quick search online, this specific passenger restraint warning alert is unfortunately a very common problem with this year/make/model and should be reviewed to see if it qualifies as a recall. BMW dealer charged $1840 to replace the seat, mat and clear the warning alert.
