Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: Here's a disturbing trend for the 2002 Nissan Altima: the engine starts burning oil like crazy, the catalytic converter goes bad, the head gasket blows and eventually the entire engine needs replacement. Sound familiar? Like a script from a horror film, these Altimas seem doomed to fail around 95k miles.

This car is a piece of junk. Changing the engine out doesn't seem to stop the problems.

Altima 2.5L

  • Automatic transmission
  • 116,000 miles

I thought my mechanic had left the oil out when changing my oil. Put 5 1/2 qts in two weeks later. It's just gotten worse. Took my good reliable car on road trip. Used 10 qts of oilo over 1600 miles. Now I'm putting 2 qts in every four days.

Just paid my car off in November and it's a piece of junk. Do I fix it or not? It doesn't seem like that fixes it either. Thought I would drive it a coupe of years before having to but a new one. That's not going to happen.

Any suggestions will be appreciated.

Same as everyone else. (sigh) I made the rookie mistake of making a quick purchase b/c I had a good impression of Altimas and this one seemed like a decent deal. Wish I'd researched it a little more before diving in.

Thanks to all of the other posts on this subject. My car was great until 100K miles, then starting burning oil. I put it in to keep up, eventually the engine light came on and then the loss of heat. Now it runs rougher than H. I made an appt to have it diagnosed

this coming MON, but after reading all the good posts; I'm S***-canning it.

I too was expecting 200K miles, very disappointing!

I keep having to fill the oil, I went to the shop because of a completely different problem and had them put a sensor on the oil gauge.. The oil light still blinks when I start it. Took it to the dealership yesterday they say they fixed it. Well, then why is it still acting up today?

Altima S 2.5L

  • Automatic transmission
  • 151,000 miles

My Nissan Altima 2003 S 2.5 recently flickered an oil light so I pulled into a gas station and checked the oil. The oil was bone dry. I put in four quarts. 4 days later I checked it again and again bone dry. I took it to a mechanic who said "these Nissan engines are faulty" and described the catalytic converter failure which effects the piston rings. I then brought it to another mechanic who said it's the piston rings. I then brought the car to a third mechanic who said "these Nissans have been known to be faulty for years 2002 to 2006" and he went on to say that "Nissan should stand by their product". I figured I would get at least 200k out of this car. I am really pissed off that I have to either pay 5000 for a new engine or trade the car in to have more money tacked on to my loan. I'LL NEVER BUY A NISSAN AGAIN.

Altima 2.6L V4

Have a 2003 Nissan Altima what went down hill quickly. Went to Nissan before my warranty expired with this burning oil problem. Paid $120.00 for a diagnoses, they claimed nothing was wrong with car. Months later car acted up and brought it to my own mechanic who told me there was an engine recall on this car. Went back again a while later. Again another diagnostic test and $120.00 for them to tell the engine has an internal engine malfunction to wait awhile and come back in a few weeks. Well went back probably 3 months later they did another test $120 down the drain for them to inform me so sorry "YOUR WARRANTY EXPIRED." why didn't they tell me that in the first place. NISSAN DOES NOT STAND BEHIND THEIR PRODUCTS. So now I am stuck with a Nissan Altima 2033 with 92,000 I can't afford to have replaced. Now after reading what others have said about their Nissan's after getting a new engine will not invest any more money into this vehicle. Will find a junk box and put put around.

Altima 2.5L

  • Automatic transmission
  • 110,000 miles

I have a 2003 Altima that I loved when I first bought it in 2007. In around 2009 I noticed that I was using oil in my car when I would have a horrible noise coming from the engine and when I checked it I would have no oil in the car. So I just continued to put oil in the car as I needed to, which seemed to be every other day. Finally the car seemed to be getting worse and worse. The idle was off, it was trying to die on me all the time, was making ticking sounds along with many others from the engine. So I called the Nissan dealer and their solution was a new engine. Well in July of 2011 I finally had to break down and get the engine put in the car. It drove good for maybe three days, then it started idling rough again, and when I randomly checked the oil in it on the third or fourth day, imagine that, it was bone dry... After this my engine light came on, the code flashed for the cat converter. So then both cat converters and O2 sensors were replaced. My car then ran good for two days. It was trying to die on me all the time and idling rough once again but the oil was doing ok. About two weeks after the cat converter was replaced I checked the oil and it was....BONE DRY.... Now once again I am stuck putting oil in my car every other day and it drives like crap. What is a person suppose to do?? Never again will I buy a Nissan.

Altima S 2.5L

Check engine light went on and car running rough. Took it for an oil change but could still smell an odor when starting up the car. Took it in to my reliable mechanic who tells me my oil is down 2 days after oil change. Suggested a new engine. Did my research on line and found many of the same complaints, same symptoms for the 2003. Called nissan Canada and waited 7 weeks for them to investigate. The answer: warranty up, can't do anything for me. So much for standing behind their obviously defective product. This was my 4th and last Nissan and last. Cheaper to drive it to the scrap yard at this point.

I bought this car one year ago used. I loved it.... Until it started burning oil and have been fighting with Nissan ever since all they will do is split the cost to fix it with me or a 1,000.00 credit towards my purchase. I still owe 7800 on the car. Why would I ever buy a car from Nissan EVER AGAIN!!!!!!!!!!!!!!!!!

Our 2003 Nissan Altima was in need of repairs. The oil level was constantly low and I needed to add at least 1 quart per week. The car would shake and at times turn off at a stop light; embarrassing, or not even turn on. We began to notice this a lot... The check engine light was on... One day it began to smoke a lot and I mean a lot, through the tail pipe. We took it in and the mechanic took the engine apart and said that the pistons were twisted; odd. He said the cause was the oil level being low and it was burning a lot, because of engine trouble. But I kept on top of it and never let it get bad... I repaired the car under the extended warranty. But shortly after the check engine light came back. About a year or so later the same problem occurred only not as bad, but it still cost us $1100, not under warranty; out of pocket. During this time the check engine light kept turning on no matter how many times the mechanic reset it. The car burns a lot oil and this last time, I checked the oil and it was fine and the next day the car was burning oil like crazy, I checked the oil level and it was 3 quarts low... I took the car in last Friday and the mechanic said that the car needed a new engine. How is this possible, when just 3 years ago the engine was completely over-hauled...?!!! Our family has owned Nissan's in the past and never had any major problems, but this Altima has been a nightmare... I will never again buy a Nissan because of this issue, I don't want to risk it happening again. P.S.... I trust the mechanic with my life; he's my father, and he has a great reputation in the community.

Altima SL 2.5L

  • Automatic transmission
  • 65,000 miles

I bought this car used in 07 with 65,000 miles on it. Within a couple months, I noticed the oil was always low and I needed to add oil in between oil changes. Being a sales person and driving A LOT every year, I seem to always be in my car driving. As of Dec 2010, I have 185,000+ miles on.. It does still run, but I have to add a quart OR TWO every thousand miles.. That is once a week or more for me! NOT CONVENIENT AT ALL!

The check engine has been on forever, but the car has not ever lost power.. But I'm definitely afraid the day I'm on a sales call in the middle of nowhere when the engine finally goes.. If Nissan is aware of oil consumption issues, it should make things right will all the Nissan customers ready to switch car makers!

2003 Nissan Altima Absolutlyyyyyyy ridiculous.

Took it to the Mechanic he said Catalytic converter... so i had that fixed $900. Then 2 weeks later the shaking and stalling and oil consumption CONTINUED. Brought it to mechanic he told me CRANKSHAFT SENSOR - $200. Didn't change a thing car kept eating oil ,shaking , stalling. NOWWW.. I took it to my mechanic he said engines saturated in oil all seals , spark plugs , coils need to be replace. This one costing me $1100. This is ridiculous how many of the same Stories are on this page i will NEVERRRR in a hundred years buy another Nissan. I just want to know and need your help. After fixing this last issue will there be something else? Am i just throwing my money at this car? Should i just cut my loses ?

  • Automatic transmission

Update from Aug 24, 2011: I am finding out that Nissan Corp was aware of the problem being a pin in the catalytic converter that eventually breaks loose and goes in and scores the cylinder walls-if your Altima revamped the catalytic converter to have a screen like shield to prevent the pin from going into the motor and get this......Nissan will do ABSOLUTELY nothing about it so you can replace your catalytic converter but you will eventually have to replace the motor because the damage is done!!! AND beware of replacement motors because they could have the same defect and you will be like me.....on the third motor and still have to put a quart of oil in it per week!

No more Nissan cars for me.....I am done and I have yet to find an attorney that will take my case and Nissan still denies any wrongdoing!!!!! Good Luck Everyone :(

We bought my teenager a 2003 Nissan Altima with 130,000 miles on it...we have had one problem after the next that have been what i consider minor. Until the other day....She called to say her car would not go over 40mph. When she would push the gas the low oil light would flash on for a sec and go off. We checked the oil and it was bone dry and it was not time for another oil change. We added 3 quarts and it drives fine again. I am really worried about it though after reading all the reports on here. We had to change the cam shaft sensor the day after we bought it and we have had to replace the alternator as well. The car does not smoke and we can not find a leak. I really hope it is not going to start drinking oil...We have only had the car since May and we paid $5700 for it...we bought from an individual who would never return our calls....we called bc the next day the car died while driving due to the cam shaft sensor.
