2003 Nissan Sentra, first notice the service engine soon light come on. Then, the car would feel like it was losing power while driving. Took it to the dealership, they couldn't find anything wrong with it but they said it might be the battery or alternator. So, they gave me a new alternator and a new battery. Then, short time after the car started losing power and just stalling completely. Power steering goes as well. As time goes on the occurrences are becoming more frequent. Several times that this has happened I have almost crashed into someone whether I was trying to make a turn or my car shut down and someone almost hits me. So, I looked up the recalls done on my mode, make, and year car and found that there were recall on parts that are causing the same problem for me. So, I called up Nissan and told them my VIN and problem and they said there aren't any recalls on my VIN and my VIN shouldn't be doing what the recall describes. Everytime I drive this car I fear that I'm going to hit someone or someone is going to hit me because this unknown reason as to why this car does this. I don't feel safe getting from point a to point b in my vehicle.
