My Sentra XE had relatively few problems during the time I owned it. Here are the ones I can remember:
The brakes, front and rear, all had to be replaced at 100,000 miles. At 120,000 miles, the brakes began to vibrate and make noise.
At 90,000 miles, the weather stripping on the driver's side door came off.
At 158,000 miles, the entire exhaust system had to be replaced due to rust.
Around 130,000 miles, the air conditioner started to smell really bad. We never were able to figure out why.
The Sentra was an amazingly reliable car. It always started up, even in sub-zero temperatures. It handled quite well in snow. The engine was not powerful, but it got good fuel economy. The interior was not very spacious -- in fact, it was quite cramped -- but that is to be expected from a small car.
I wish I had kept it for a while longer instead of trading it in toward a newer American car.
I will definitely consider a Nissan when it comes time to buy a car again.
Very good car indeed!!! But don't judge to quickly, I had to drive my American car a lot of times when my Sentra was broke down!!!
I've had fewer problems from my Chevy Silverado. My Sentra has all the same problems as yours does, plus a few more. Fortunately the previous owner replaced the exhaust. The weather stripping on the doors hangs off and the roof material has dry rotted. I hope it will start doing better, but it does have high miles already. I've put 1500 dollars into it in the last month. I could have just bought gas for the chevy.
AC smell issue can be tended by spraying a bleach and water mixture (5 to 1) into the intake grate located at the rear of the windshield while the AC is on, through a hand pumped spray bottle.
