On October 11, 2013 I was driving vehicle at about 30 mph. The traction, brake, and check engine light started flashing. The engine started to accelerate & decelerate at random and vehicle jerked (intermittently) all mentioned lights then stayed on constantly. Vehicle was driven to dealership. Dealership scan tested & found steering angle sensor code in history, then recalibrated steering angle sensor. Vehicle was also serviced for recall regarding lower control arm (replaced). 2nd incident occurred on 10/22/13. I started car in the morning, and all the lights came on. Vehicle was shut off and then towed to same dealer. Service technician could not "duplicate" code. I was told by service that car was fine/operable. 3rd incident occurred on 10/23/13. I was driving and vehicle brake light, & trac light came on. Car was again jerking/surging and accelerating and decelerating at random. Vehicle scanned by technician and multiple "can" codes and steering angle sensor communication code found in history. Technician called technical assistance and was advised to replace motor driven power steering unit, replaced steering column with power steering unit, all ok after repairs (per dealer). Rental car charge incurred totaling $26.28. 4th incident occurred on 1/2/14. I was driving vehicle and traction control lights, brake light, and ABS brake started flashing. Trac light then stayed on constantly. Car began jerking (again) and accelerated/decelerating. Vehicle taken to different dealership. Service writer test drove car while I was in vehicle, and stated there was something definitely wrong w/vehicle and that it wasn't safe to drive. Rental car obtained. Technician looked at car, called support, and was told to charge hybrid battery. Service writer called back and stated that car was ready to be picked up. I refused to pick car...

While coming to a stop at a traffic light, my brakes malfunctioned. The brake warning light came on and the peddle became slack. The peddle fell to the floor. I was able to stop the car before entering the intersection. After a moment the brake warning stopped and the brakes worked again. This happened again as I was parking my car in the driveway. I have video of both incidents. Dealer has been notified, but is not able to schedule a repair for 5 days. It will have to remain parked as I am concerned about safety.

As I was gently applying my brakes in heavy freeway traffic, going about 50mph, the brake pedal became soft and dropped to the floor. The brake failure warning light also started to flash and chime. I swerved off to the side of the road to avoid hitting the car in front of me and plowed through some plants on the shoulder prior to coming to a stop with my parking brake.
