NHTSA complaint #10949829, filed 2017-02, 10 miles2016: “Putting this car into park will normally automatically set the parking brake. Earlier that day, it did not set the brake. I assumed I must have hit some button or something on my dash to cause that. But then on the freeway, the car (for want of a better term) started wiggling and I found it hard to control it with the steering wheel. It stopped doing that for a few seconds, and then immediately happened again.
