On the early morning of 03/08/2016 around 5:50am on my way to work, the car lost all power as I was trying to turn left on to a county road. I was able to steer the car out of traffic coming from the opposite direction and almost went down the ditch due to the steering was very hard to turn. I put the car in neutral and restart the car continuing to get to my destination. At the next intersection, this happened again as soon as I used the turn signal (I was turning right this time). I restart the car again after put it in neutral. This problem is now will occur each time I use either turn signal left or right. I consider this is a safety problem because accident can occur if someone didn't know how to react when it happen the 1st time on a busy road.
The vehicle engine shut down and had to be restarted while rolling. Every event usually involved turning and braking at the same time, but occasionally shut down while idling at stop lights. It appeared to be similar to the ignition recalls that have been made on other vehicles, but not on this particular model. It has occurred several times and at least two to three times while turning onto on ramps to freeways. It always requires shifting into neutral to restart and very stiff steering because power steering is disabled. This has occurred in traffic and presented very hazardous conditions. I believe the ignition is at fault, but cannot say positively. Usually occurs when the car has been driven for some time and the engine has been running quite some time and is considerably warm. Under hot conditions it occurs more often.
