I purchased this vehicle thinking that it would be a safe car for my family and friends. The transmission seems to be slipping and an excessively harsh 2-1 downshift occurs when decelerating to a stop. Also, transmission "bangs" into gear when accelerating from a full or a "rolling" stop. This occurred several times on a daily basis. One time in specific I was driving with my 4 year old niece and it caused her to become alarmed as well as injure her neck.

Vehicle slips in an out of 5th and 6th gear when traveling at constant 35 to 40 MPH in auto mode and around 60 MPH in ds mode. Noticeable oil leaks as well as occasional smoke from tailpipe and vehicle bangs into gear ( while downshifting on occasion) also noticed that the electrical system seems to cut out for a split second while driving. Heads up display and radio illustrates this finding as they shut off for a second. The clock is also behind a few minutes / week because of this.

Not too long ago I had my car parked on a street on a sunny day. I got in the vehicle and started it and received a message on my idrive saying that there is a passenger restraint system malfunction and a airbag light along with the seatbelt light lit up on the dash. Dealer says that there is no recall for this issue yet online I've read that my model does in fact have a recall for this issue.
