general problems of the 2012 Nissan Sentra

I was getting on the freeway all of a sudden my steering wheel gets stiff and my car comes to a complete stop traffic is going at full speed me and my children could of being in a serious accident and then a few minutes later the car is back to normal. I would really appreciate if it's looked into someone can get hurt.

Driving down the freeway then all of a sudden my car lost 90% of power and could only go about 25mph. There was no warning. Car jerks violently steering becomes harder. You try to punch down on the gas and nothing happens. Also was forced to take city streets due to not being able to go a safe speed to stay on freeway/highway.

Cannot move car out of park.

Power steering assist (electric in this vehicle) suddenly failed while driving on city street at 25 mph. The "ps" warning light came on car had been driven about 5 minutes before this incident, and I had just made a right turn. Steering became difficult, but I was able to return home. The next day, I started the car and drove around the block; the power steering worked and the warning light was off. I have not driven this car since then.

Tl the contact owns a 2012 Nissan Sentra. While stationary and while driving various speeds, the steering wheel made a squeaky grinding noise and shook when being turned left or right. The dealer and manufacturer were not made aware of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 86,000.

The vehicle drifts both directions while driving, when braking it seriously pulls right. I have only had the car 6 weeks and haven't hit anything yet but if there are narrow lanes with parked cars I may not be so lucky. There are other problems the heat shields that cover the exhaust come loose and the air sensors in the tires leak so you need to put air in the tires weekly.
