Car squeaks/squeals when in reverse
Kinda hard to explain the noise, its kinda like a low tone squeal. Happens when I drive slowly in reverse, like when backing out of a parking spot or driveway. It doesnt happen all the time. My dad heard it one time while I was home visiting, he said its caused by the rainy weather, but I've heard it when it was nice and sunny out.
Its very loud and noticeable, definitely a sound you shouldnt be hearing from a car thats only a year old. |

My car does this as well. I think it is caused by the e-brake sticking a little, but because I have MT I always use e-brake so I have never tried without. I mentioned it to the dealer when I brought it in for service and their response was vague and unhelpful. Mostly just told me to live with it.
My brakes were squeaking as well due to an improperly installed sensor that was prematurely rubbing. Now that I think about it, since they replaced my pads/sensors for my brake squealing issue, I have not noticed the reverse squealing issue either. Perhaps that is the cause? |

Mine has also done this since day one. Dealer was able to replicate and sent the symptoms to BMW. They replied that there is no fix and to send me on my way. It's pretty embarrassing.

I wonder if the hill assist is causing it somehow. Like its not fully disengaging.

It's the E brake sticking, mine does this also if I fully engage the E brake to park. I hate it also so now when I park in public I'll leave the car in 1st and only pull the E brake if I'm on an incline and even then only 2-3 clicks. This works for me.

It's been a pretty well documented issue. It's generally not caused by your e-brake, but rather the front pads from when you last applied them when you parked.

I notice something similar to this with my car--I would almost call it a groaning sound. The acoustics of parking decks made it most noticeable. The dealer said it was a wear sensor, replaced the rear pads and the noise went away.

I have that on my E90 on top of the squeaky brakes when you start moving and then stops after passing 20mph.

Same thing happens to me, and I only have like 1000kms on it. I was thinking about going back to the dealer but I see this is a common thing now...these forums rock

I've been getting this squealing noise too in recent months, when backing out of my driveway. It only happens after the e-brake has been used. Earlier in the summer I heard it every morning, but now just once in a while.
I'll mention it to the dealer again on my next scheduled visit, but all in all, considering the more serious problems I've been able to avoid thus far, I'm 99% satisfied with how reliable this car has been, and this is not something I'd lose sleep over... |

So I didn't engage the e-brake last night and this morning I had zero squeal.
Pretty silly that I can't use my e-brake in order to avoid my car sounding like a hoop-die, but it's worth it. |

I brought my 135 cab in yesterday. Had them adjusted the e-brake and will update if the noise returns. Interesting thing is adjustments aren't covered under warranty, but now that I paid once it has it's own warranty.

Its the ebrake, and it happens on reversed, changing pads does not help, i just had my pads replaced about 30 days ago.
the fix for me is to disengage the ebrake, engage and disengage again... works every time. |

I was told to rinse the brakes when I wash the car. I put the hose right up to the brake calipers/pads and rinse it for several seconds. I was suprised to find that this works. I had the squeal in reverse but rinsing the brakes will stop the squeal for a week or so. It is not a permanent fix but it does stop it for a bit...usually till the next wash. The more water pressure the better!
The BMW dealer recommended giving my brakes some repeated hard use to stop the squeal. I have had mixed results with this. I tried it a few times with no luck. After some serious braking one evening I stopped the squeal for a while. However, we are talking some repeated serious threshold heavy braking (and some serious brake dust build up!). I would say this is not a good route to try. |

Twice in the last 2 days I've heard my main brakes (Brembos up front) faintly squeak during normal driving. Its rarely and not all the time. Its probably nothing, but its definitely coming from my car.

Sounds like a brake issue to me... I have heard and seen it diagnosed three times properly and several times with solutions that didn't solve the noise issue. I am not sure about BMWs but all past experience tells me that it is a brake issue...
Best of luck, -NurEinser Quote:
