I had just started driving down the road 2 miles and going around 25-30 mph and the car shut off and the steering wheel locked. There was cars behind me and I was able to put my hazards on. Thankfully cars were coming up to stop sign so I was able to steer off road. Started car up and drove a little further and car shut down again and locked steering repeated 4 more times til was able to get home. I was getting ready to get on freeway with my young kids in the car could have been so dangerous.

I was driving home from work and my transmission began to not shift out of third gear going up a hill.. I took it to the dealer after this happened another 10 times and they said is a intake flap not closing properly and that they couldn't do anything about it. Now its happening so often im afraid to put my children in the car on account that every time it stops shifting when I'm in the middle of traffic and lose all power.
