2012 BMW 135 Owner Comments

problem #1

Apr 102012

135 6-cyl

  • 2,000 miles


Have taken the car five times for the same stalling, and lagging of the faulty dual clutch transmission. The car hesitates 3-5seconds no response to throttle input and then lunges violently forward. Car holds gear when pulling away from lights and then surges when parking the car almost causing me to hit cars parked next to me. Software has been updated on the car four times and the issue is still there. Was told that the mass airflow sensor was also faulty in the car and that might be causing the issue of surging and fluctuating idle. Mass airflow sensor was replaced and transmission issues as well as idling issues are still present. Take the car in for squeaky brakes and was told that the sound was normal, week later car is shaking violently when slowing down on the highway. Upon inspection the front brake rotors are warped and all this has occurred on a brand new car with 12K miles and less then a year of ownership. Car is also plagued by electrical gremlins that keep firing off the TPMS sensor warning lights that stay on after a reset and verification the tire pressure is as stipulated by manufacturer in the door jam.
