While driving with the lane departure system on and cruise control on, the vehicle would unexpectedly brake for no reason. this happened several times. with lane departure system on and cruise control off, the vehicle would occasionally give a "brake now" warning for no reason. dealer claims that the issue has been corrected but it is unknown if this is correct.
Severe pulsation of braking system after only 6000 miles. dealer resurfaced warped rear rotors. at 10080 miles the same problem has come back and car is being repaired again.
I was driving on a highway and i wanted to slow my car down because i was approaching a construction area. when i applied the brakes the break pedal went right down to the floor. this total break failure did not allow me to stop my car.
Brakes locking car would not stop
Vehicle shakes at high speed when the break is applied. cause by rotor warping. the deal had re-surface the rotor and replaced break pad one already. but it still does same thing.
Brake noise: brakes make a loud thumping/knocking noise when i step off the brake to start crawling from a complete stop in 'drive' mode (i.e. at a red light or stop sign). here are videos which demonstrate this. this happens very frequently and is loud. and in rare occasions, the brakes make a squealing noise. overall, the brakes are working (e.g. i can use them to stop fine) but these issues are frequent enough that it's concerning, irritating and really, just completely embarrassing to drive with such a high-end brand. please see the videos below which highlight these noises. i noticed it also happens when i'm shifting around from park/reverse/drive when i'm the parking lot (sounds like the car is regurgitating). again, this is very concerning (i.e. is the brake going to give out some time without me knowing), annoying to hear/feel, and quite embarrassing as my passengers as well as folks outside my car can hear it. i feel it's unacceptable for such a new car. any suggestions​ on what i should do? has anything come back from service bulletins or the engineers in california? i noticed some tsb's related to the brakes.
