general problems of the 2005 Nissan Sentra

My check engine light comes on and the car keeps running hot after I just got the coolant flushed.

The car suddenly died about 7/27/2015. It just shut off while my husband was driving and luckily he was at a light and no one rear ended him. Then on about 8/27/2015 the vehicle died while I was operating it. It restarted after a few minutes and drove about a quarter mile and died again then I managed to pull into a driveway but was blocking people from enterering or exiting. My husband came and pushed me out of the way. Then while I was calling for a tow, the car started again and I was close to home so I hoped I could make it. My husband was in his vehicle and followed me and the vehicle died again in about another 100 feet but I pulled into a business center. My son and husband pushed my car for a little momentum as my tail end was in the street and I parked the car there for a few hours and when it seemed to cool down a bit it started. Then today, I was close to making it home and the car died on the same busy street and would not restart. A good samaritan came along and pushed me to the same business center. Again, we went back later and the vehicle started. This is dangerous because especially yesterday, many people nearly rear ended me because you could not see me because I was just over a hill. I see Nissan has recalled some vehicles for this issue but mine is not one of them and it should be. This is very dangerous and someone could be seriously injured or killed if it were to die at a bad time or if someone who is trying to help gets hurt. Please help.

Comments: my daughter, cassie breen, owned a 2005 Nissan Sentra which had to have the cam position sensor and crank position sensor replaced on 4/9/14 after the car quick running while driving home from work. She was idling at a light, and the vehicle stopped accelerating when she tried to proceed. Since then, she traded the car in. In researching 2005 Nissan Sentra recalls, there is a recall NHTSA reference #07v527000, which is for the crankshaft position sensor on 2005 Nissan Sentra vehicles with a 2. 5l engine. Apparently, her vehicle does not have this engine but, amazingly, had the same problem. I spoke with a Nissan rep, melody, who just repeated some standard text she was reading, which did not make any sense to me. It seems my daughter's Nissan had the same issue as that in the recall.

1) I heard that airbags on my car may not function as they are designed to do. There may be a recall. Please advise. 2) for the past 3-4 months, I have noticed a thumping sound/vibration when I press my brakes. It doesn't do it everyday. Some days, after the car is driven a few miles, every single time I use my brakes the first time I noticed it, I was driving and had to put on brakes suddenly and I heard it. Now it still happens, but I hear and feel a thumping underneath the floor on the left back-when there is a passanger sitting behind the driver and this sound occurs, they report to me that they can actually feel the thump under their feet. Other days I don't hear it all. If I have a full load of four people, I hear it and feel it frequently. Sometime it sounds like its under the trunk or in that back seat area. We had the car examined by a local reputable repair shop, they did not hear the thump and stated they would have to hear it or feel it in order to make any repairs. . They did examine the car and found nothing that should be making this noise, in their opinion. Do you have any suggestions on what is going on. Curret mileage: 172,000. Cell phone: 334) 549-7797.
