Replying to: pure_hp (Feb 11, 2008 8:20 pm) The Altimas themselves are lovely cars and are fun to drive. My daughters 2002 is a dream to drive, she really loves it. I think almost everyone who drives them loves them. It's just the people who have problems with them get disgusted with them, but who can blame them? Since I fixed the engine in my daughters 2002 Altima, it is again a dream to drive. It was a really nice test drive after I put the engine together, I spared it no mercy, slammed it through the gears, blasted to over a 100 mph pretty quick for just a little 2.5L engine! It drives great and handles great. They are great cars, its just a shame that some have these problems. I have been researching the problems with the engine, trying to figure out what the problem is or was, and this research has been ongoing, even until now. I started researching and thinking about this since September 2007, when the cat clogged up on the 2002, and I unplugged the cat. Then I went on to therorize how the oil consumption problem was related to the cat converter failure problem, and they definitely are related. Then I had to tear down my daughters 2002 in Dec 2007 due to head gasket leakage, to replace the head gasket and repair the head. I think that the head gasket problem had to do with the engine overheating more than anything else. But in the process of repairing the engine, I made sure the cats were all unplugged, and they have not been a problem since then. It seems that the oil burning is greatly reduced (I will be able to confirm this in a few months). My daughter is driving it every day, and says it's running great. My thoughts at this time is that the real problem was not in the engine, but in the defective cat, which then causes the problems in the engine. In taking the engine apart and putting it together, I was quite impressed with the design of the engine, and it seems to be built to be quite reliable. I have also continued my research looking at other make and models of engines, and found that the other makes also use the same type of layout and design of the exhaust and cats, and are not having these problems, which further leads me to believe the oil consumption problem in the Altimas was due to bad cats, cats deteriorating, and NOT from bad design. So it seems to me that if the cat is good and does not break down, the engine should last a long time, a normal lifetime. So hopefully Nissan took note of the problem and is putting better cats in the newer cars. The only thing is, the problem will not show up until much later, if it shows up at all. Time will tell. In summary, I think if you buy a new Altima and drive it for a few years, and then trade it in, you should be fine. I think the main concern should be for those used car buyers who are in the market buying 5 or 6 year old cars out of warrenty with about 80,000 or more miles on them. They may not be aware of the problem and buy the car, and then have the engine go out shortly thereafter, a very unfortunate disaster for a young hopeful buyer. Good luck and happy driving, E.D. in Sunny Florida

Replying to: pure_hp (Feb 12, 2008 5:15 pm) different people have different opinions and experiences when it comes to reliablitly, but this is my third nissan product. the first one, a sentra, lasted 220k miles with no major repairs, and was traded in still running. My second, a 1998 200sx, has 151k miles, I still own, is still running, and I drive it to and from work (about 50 miles per day) four days a week. in the 10 years I've owned it I've had to put 2 sets of front brakes on it. Thats it. brakes twice in 10yrs and 151,000 miles. those two nissan vehicles are the reason I bought my altima over a camry, accord, or other mid size. |

let me start off by saying i'm new to this forum....i have a 2002 altima 3.5(auto) with 62000 miles...recently i have had problems accelerating when getting on the freeway or just playing around...it seems to be bogging around 3500rpm to about 4700rpm and then open back up to redline..its very annoying and i'm worried..i do have a couple upgrades like a cold air intake, exhaust and no resonators..i have heard that it can be either the mass air flow meter or tranny problems...has anyone had this problem and what do i do??
