The last couples of times I've started my car, there have been a metallic snapping sound when it starts moving. I also need a little power to get it rolling (the car have been parked for two days).
I would have understood this if I parked with the handbrake. But I have an automatic and park my car in a garage, so I only set the gear shifter in P.
I don't believe that this is the brakes sticking to the disc. But what could it be? And most important, do I need to worry?

BTW, I have a 3 series F30 (2012) with automatic transmission.

Uncle had same problem with his Lotus Carlton, after a trip he'd park in the garage & brakes would stick solid, even had to call AA out couple of times. I think it's when the brakes are hot they sort of bind together, try not to use much braking 5 mins before you arrive home & see how you get on.

Mine does this after washing and leaving for a few days so the brakes bind on the rears, don't think its anything to worry about.

I had this happened to me just 2 weekends ago when it rained heavily. I parked my car on Friday and the car stayed stationary on Monday when I put it in Reverse. I thought I put it in neutral by accident. I looked and sure enough I saw a "D" on the dash so I gave it some throttle and the car broke free with a slight jolt. The rust buildup on the rotors acted like glue and caused it to be glued to the brake pads.

So the brakes do get stuck, even if you don't apply parking brake when you park the car?
If that's the case, I don't need to worry.
And btw, I did wash my car just before this happened.

Yeah it's no big deal, just the corrosion on the rotors and pads sticking together. Happens all the time, just apply the brakes in a spirited manner once or twice from regular speeds and it'll clear everything off.

Hi, I've had this issue but if left for a week or so,it take about 50 miles of hard braking with a lot of vibration and judder till things start to get back to normal. Seems to have wrecked the discs too which I'm being advised to replace after 26k miles! Apparently the brakes sticking and the judder is normal and happens on all cars!!! Has anyone else had this issue and got anywhere with the dealer? Don't fancy replacing discs and pads ever 26k miles!
