My car according to carfax was manufactured in july 2003 so its a later 2003 model, still had the problem.
 
just got the engine fully replaced 2 days ago at 61000 miles along with the pre cat
 
car drives beautifully now, still plan to have the pre cat hollowed out, i dont want to take any chances on this thing happening another 61k down the road. a car should not need a 3rd motor at 122k miles, nonetheless even a 2nd one at that many miles
 
me being 19 however and wanting my first car right away i didnt even do the carfax report before i bought my 2003 altima 2.5 s
 
i had actually done the report a few weeks ago and found out my car was once a rental car back when it was brand new
 
mechanically speaking even before the engine was replaced the car seemed fine and drove fine
 
i will need an alignment sometime in the future but it is not a major issue at the moment. i also may need to change the timing belt
 
since ive had my new engine though i hear a weird noise that sounds like water rushing through some kind of pipe when i start the car, and also when i accelerate. does anybody know what that might be all about?

That swooshing noise is dangerous if you don't fix it ASAP. It may cause head gasket failure($1200 repair). It is easy, Park the car uphill (radiator at the higher level). When engine is COOL, Open the radiator cap (check the condition, you may need new radiator cap), Turn the heater and fan at max, Start the car and squeeze the coolant hoses to remove any the air pocket inside the coolant line. Top the coolant level up (both on the radiator and reservoir) and replace the radiator cap.
 
I had that problem but it was fixed after do that steps and install new radiator cap from Autozone or dealer . My previous radiator cap was swelling caused by oil residue from the head gasket replacement.
 
Your car has TIMING CHAIN (no need to be replaced until 300k miles), If the car go straight on the FLAT road and the tires have no unusual worn, you don't need alignment. You may need to replace the front struts, passenger side and rear side engine mounts if you race the car a lot and the brake pads at arround 80k miles city driving.

that noise actually went away i no longer hear it, car pulls to the right ever so slightly on flat roads
 
never race my car, i care about it too much to do something like that, i never go any faster then 70 mph anyways because my car would start to guzzle gas (my average mpg according to the trip comp is about 25.5 mpg)
 
tires are ok, the right front tire is almost bald, the other 3 are very good, havent bought a tire due to serious lack of cash at the moment

Alignment by rondhol

If your front tires are match (same brand and date installed) but only right side is worn, then you need alignment. Change the tires in pairs 2 or 4 at once. The pulls to the right effect caused by lower (worn out) right tire. You can buy good brand (Micheline, Good year, etc, NOT CHINA tires) used tires in pair for less than $35 each. but read this first: http://www.carbibles.com/tire_bible.html
 
By the way, check your radiator cap , coolant level (both on radiator and reservoir), and the hoses after the engine is cold (if it is collapsed).

Hi! I have a 2002 3.5 liter Altima and the problem with the cats is prevalent throughout my ownership of the vehicle. I have had 5 cats replaced, and the last time, Nissan forgot to put oil in my car and I battled with them for a year, and they replaced the engine and cats with all new Nissan factory parts. Well, the new engine has less than 10,000 miles on it, and the cats started coming apart internally just like always. I had a mechanic friend hollow out all the cats and in the process of doing so, we noticed the resonator pipe had a big crack in it, which no doubt was leaking exhaust. He removed the resonator completely, hollowed out that cat, and then welded a new pipe in place of the resonator piece. The other two cats up in the front of the car were also hollowed out. The very front one, the hardest to get to, closest to the heat shield was virtually impossible to hollow out. The core if the catalytic had hardened into a solid mass, and there was absolutely NO AIR able to get through it. The mechanic couldn't hammer it, drill it, use a saws-all on it - NOTHING was going to break it up to remove it. So my friend cut open the cat in the middle, and grinded the catalytic core material out of it, and then welded it closed and put the pipe back on. Now, the SVC engine lite (obviously) has come on, and the exhaust leaks right into the cabin of my car and it's unbearable. I don't know if there is a leak at the weld spot from my friend or what, but I need to know what to do to make this car run right and not asphyxiate me in the process. Replace the left bank cat and leave all others hollow and then tweak the 02 sensor? Please advise if you are able! I really appreciate it very much!!
 
Sincerely,
Sara Keil

first of all, Don't bring your 02 to that Dealer again.
 
3.5L VQ engines rarely have pre-cat problem. Since you have new engine and cat, may be the culprits are MAF sensor, ECU update, or EGR system. If it runs too lean/rich, your engine and cat will be bad faster. Check the sparkplugs to confirm rich/lean mixtures. Buy header instead of breaking your head finding the leak.

Definitely try to find another Nissan dealer, better yet look up reviews on local nissan dealers and see who has the best overall reviews and choose the dealership with the best rep.
 
The 3.5 SE v6 engine is a much better build then the 2.5 S, i actually wish i had spend the extra $1100 for the 04 altima with the v6 engine then the 03 2.5 S.
 
Im suprised that the V6 has this problem as well, considering most V6 altimas are virtually problem free.
 
My advice to anybody buying a Nissan Altima made between 2002 and now, spend the extra money and sacrifice the gas mileage for the v6, you'll have much less issues then with the 2.5 v4.

The 2002 3.5 is FAAAAR from problem free. Almost every single person that I have seen at the dealer, on the street, or in any forum has the same problem as me - the cats go bad, come apart internally, and the particles get sucked out the exhaust, or if not that, then you have NO POWER. The design of the entire exhaust and cats is BAD. Replacing the cats on any car more than once in a 100,000 miles is ridiculous.

Get a lemon law lawyer and sue. If you bought it used - your screwed - but new - the law is that any car that has had the same problems 3 or more times in a row is a LEMON and the dealer can do one of the following based on whatever choice YOU make - 1. Give you a full refund for the car (original prchs price) as well as reimburse you for any and all expenses related to the repairs...including rental car bills. 2. Give you a new vehicle of equal value and reimburse you for the expenses related to repairs. I WISH I HAD DONE IT AT 40,000 miles. But the cats are warrantied for 80,000 miles so I went ahead and kept the car. I battled Nissan North America for a year and they finally gave me a brand new engine and cats plus reimbursed me for ALL my expenses related to only the catalytic problems and ALL the frigging rental cars which was over $8,000 in cash. They wanted me OUT OF THEIR FACE and once I threatened to sue them for about $80,000.00 they straight paid to have me be gone! Good luck to you!

2002 Altima Engine Failure by brossr

I have a 2002 Nissan Altima 2.5 S which I bought new. It has always has all recommended maintenance performed and all maintenance has been performed by the Nissan dealership. The other day the check service engine soon light came on soon after I started the car. A couple of times in the last few days I had noticed that when I first started the car in the mornings it ran i little rough (not much) for about 5 seconds immediately after starting but that was barely noticable and almost immediately stopped after which the engine ran perfectly. I decided to drop it by the dealership and have it serviced. The last maintenance (oil change) had been done about 3000 miles ago, so it was time for scheduled maintenance, so I was also having the oil changed and the tires rotated. After about an hour the service guy came out and told me that the code on the service engine soon was a "cylinder 2 misfire." He said my antifreeze was a little low and they were doing a compression test as it could be a head gasket problem. He said the slight roughness for a few seconds when the car was started in the mornings was probably because antifreeze had leaked into the cylinder and once it burned off (a couple of seconds) the roughness went away. Because it was going to take them a while to do the test I told them to just call me when the car was ready and I left and went on to work. Serveral hours later the service guy called and said it was a
head gasket problem, but he really thought I needed a new engine ($5300). They had found a little coolant in the cylinder and he said my oil was 1/2 quart low and although the catalytic converter didn't show as bad, he was afraid that if I just had the head gasket replaced ($1800), the engine would still probably need to be replaced and the head gasket replacement would be for nothing. This car only has 66,300 miles on it, has always has all recommended maintenance performed by the dealership, and has never been driven "rough" as I am a very conservative driver. I have read about other problems with this engine and the catalytic converter (or pre converter) failing and resulting in engine damage requiring engine
replacement. This has really bummed me out. I bought this car because I was told, and had read, much about Nissan's reputation for solid cars that ran a long time. Now, here I am with a car with only 66,300 miles (it should just be getting broken in good) and I'm being told that I should replace the engine. If a well-maintained, conservatively driven car has engine failure at 66,300 miles, that sure seems like a
manufacturing defect to me. I have read that the catalytic converter is warrantied for 80K miles and if this is true, and it had anything to do with the engine problem, it seems to me that this engine should be replaced by Nissan, especially now that I have read that this is a somewhat common problem with the 2002 Altima engines.
 
I picked the car up and told them I would have to decide what I wanted to do. He said when the light came back on to bring it back so they could see if it gave the same code and he wouldn't charge me for that diagnostic. He also told me to check the oil about every 3 days and if it went down, don't fill it but bring it to them and let them see how much oil was being used (oil comsumption test). It's been five days and no service engine soon light, the oil level is fine and the car runs fine; there is not even any roughness when I initially start the car in the mornings as I had noticed a couple of times previously.
 
Does all of this sound right? I'm not sure what to do and the thought of having to spend over $5K on repairs has me sick.
 
FYI, I went back and read all the posts on this forum and it seems as if some people have been able to get Nissan to cover the repairs and others have not. If I do have to pay for a new engine myself, would I be better off price wise trying to find a good independent mechanic to do it? If I have to pay for all of this myself, my faith in Nissan will be destroyed.
