M340XI 3000 miles impressions

Hi guys,

As I drove the car for 3000 miles I want to give me impressions so far.
At first when I bought the car I was super impressed, the car was absolute monster.
However yesterday I did 1300 miles trip without rest and ... of course the car decide to break.
First it happened while I was driving with driver assistance on(car handling by it self) my cluster went pitch black and then restarted with error message "Driver assistance restricted..." I tried it again and again after 30-40 minutes same thing happened. SO I guess something with the driving assistance is broken... At the same time I notice that whenever I'm driving between 120 and 133 km/h and I press the trottle I heard some kind of metal noise.... if I release the trottle the noise is gone, I tought this is some kind of exhaust noise because of specific rmp, however if I downshift the sound is still there so it has nothing to do with the RMP ... it's just some sound that drives me crazy.
So basically 2 problems for 1300 miles trip and car has only 8000 miles on the clock.. I'm really disappointed I can't imagine what will be when the car is like 5 years old and has 80+k miles on the clock...

I really expected way more for a car that cost 80 000 Euro in my country. I even consider returning it, but I don't know if that's an option since I already gave 35% initial pay.

Even with the vastly improved mechanicals in today’s cars, the constant addition of electronics and computers grows exponentially the potential for issues. It makes you seriously consider extended warranties just to cover the gizmos in the car.

I did a 3000 mile trip with it over the summer and it blew all of my expectations out of water. Zero complaints.

We just came back from a 1200 mile trip and results were the same.

I now haver over 13K miles on the car and it has been 100% problem free.

Not sure what country you live in but that is what warranties for.

Well, it's under warranty, right? Take it to a dealer if you notice the same issues again. I did 1,800 miles in 24 hours in my 330i and didn't have any such issues. I don't have DAP, though, just used regular cruise control. The only issue I had was the power steering seizing up towards the end of the trip. Turned it off and let it sit for 2 minutes and it's been fine ever since.

That's any modern car one of the most unreliable cars I've ever had was a Honda Accord. No manufacturer is 100% issue free it's the luck of the draw
