It is my expectation that nothing goes wrong at all until there are at least substantial miles on it (50K+).

no kidding. infuriating that some ugly little toyota s***-box can be abused for 200k miles with nothing wrong, but something expensive and nice is a ticking timebomb.

if nice cars were as reliable as many of these little turd cars, I'd probably buy something in the $150k price range and keep it for 20 years or more.

I drive a 2015 335i and also had the drivetrain malfunction pop up today. The car only has 890 miles and was on the highway when it happened.
I immediately stop at the nearest gas station and turned off the car and turn it back on and the drivetrain malfunction went away.
Im not sure if it was me or was it a one time thing because i haven't had it pop up again.

Should I be worried?

I would take it in. It might just be sensor related, but my understanding is when you get that message it's best not to mess around and hope it's not a problem. Hopefully it's nothing major.

Had the same issue at 1400 miles, Car was undriveable, ended up being a bad camshaft position sensor.

You have long way to go~

I had this issue. It happened and went away in a few seconds. Turned out to be Fuel Rail Pressure Sensor.

I'm really hoping Bentley releases the factory service manual for this car before the factory or extended warranty expire.

[Billfitz]

I bet the proliferation of sensors is more than a small part of the problem. I was poking around under mine the other day and noticed wires attached to a sensor that was on the exhaust pipe just in front of the muffler. I've never seen a sensor on an exhaust pipe, and can't imagine what the heck it's doing there. Obviously it serves a purpose, but I doubt it's a purpose that really is necessary. I bet a lot of these warnings are for minor concerns that other cars suffer all the time with no major ill effect, but since other cars don't have a zillion sensors you just never know about them. Sometimes being blissfully ignorant isn't such a bad thing.

[geddylee]

So I just got the car back. Here are my concerns -

1. The new turbo spool is much louder particularly under WOT off the line until you get to about 3rd or 4th gear. When I bought the car I never really could here the turbo spool up or maybe you guys have noticed this?

2. It appears to be putting down significantly less power off the line. Before the drivetrain malfunction I could barely get a smooth launch without traction control intervening. My buddy with a new 435 says his is the same way, now my car is smooth off the line and even in Sport I can seem to stomp on the car without ever feeling like traction is an issue.

What would you guys do? Are these issues significant or should I give the new turbo some time to break in?

I had same issue with drive train malfunction warning. I only have 1700 miles on the car. The car was idling in my driveway at the time and it disappeared once i turned car off and back on. I didn't feel any loss in power when i drove but i did bring it to the deal to get checked out. They ended up telling me there was a software update that my car never received but BMW was very aware of the problem and the update should fix the problem. I haven't driven it much since the update but i also haven't seen the problem resurface yet.

This shit started to happen to my car about a year in, right at the beginning of summer. Of course i took it to the dealer who after 3 days "figured out" i had a broken sensor. Few more days and got the car back. Three weeks later, same problem again. Took it back, they said it was something to do with the insulation !?!?!?! They said they fixed it. Of course not, happened again after few weeks...

Then i realised that all it takes is for me to stop, turn the car off and back on, then it was working again. Funnily, the problem seems to occur in the summer when it's very hot outside, never had it in winter. After a while, i got used to it as there was no point in taking it to the dealer that often. I didn't know that many people had the same problem, it's obviously a serious issue that BMW should pay more attention to - if they cared that is...

if you've had the drivetrain malfunction issue with your F3x and want to explore filing a lemon law claim in California, feel free to message me

I've made it 12K miles without this error. Did get a low coolant warning at 8K and brought it in. No limp mode and error went away after I shut it down and started it up the next day, but they said it did have low coolant so they added some but didn't find any leaks.

Did you ever resolve this? Wondering if you timed the 0-60 or dynoed it. Or used the sports display on the idrive to see if you were getting the same power.

This actually happened to me when I was racing a Audi s7 on the freeway. The owner was shocked at what my 335 could do

After a quarter mile or so in my engine made a loud revv noise for longer then usual. Then up came the malfunction reading.

Took it in and it was fixed with a simple recoding to remove errors. No engine damage

[dannytea]

got mine at 18,000 miles. luckily i was coming off the highway ramp when it suddenly went into limp mode

These are good suggestions. Ultimately I just decided to live with it, though the whistle noise did get better with break in. Mine is a 3 year lease so it will be going back early next year and now I have to figure out what the hell I'm going to get next.

You've gotta pay to play. Old econoboxes run forever, yes, but they also don't do anything fancy. The more toys, the more problems. A good way of getting a reliable luxo car with luxo features is get a lexus. For now anyway... they're moving to a TT V6 soon but I'm sure they have tons of resources going into making in bulletproof.

[MarkM5___15]

This shouldn't happen at 1,100.. Were you doing any launching or burnouts? I'd bring it back to the dealer asap.

[Billfitz]

He brought it back to the dealer two years ago.

Yes, and thankfully 24k miles later I have not had a single issue with the car. The F30 maybe a step back in several areas, namely interior quality and driving dynamics, but it's the most reliable BMW i've ever owned and I have had 8 BMW's over the past 15 years. It's a good car.

[SteveinArizona]

CR gives the F30 and its ilk good reliability reviews. So these are probably not representative

[Billfitz]

No car is any more perfect than the people who design and build them. Google 'Lexus complaints'.
Note to self: pass on the RX350.
