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.

While driving on the street and about to turn the car suddenly stopped running while driving. Since I was in the middle of a busy intersection, another driver came to help, he asked what happened, I said "I don't know". he got into my car, shifted to park and started it. Weird I said, and forgot about the incident until months later happened again, then months later again, the "service engine soon" light never came on so even I took the car for service and asked about the issues, it was never detected, but I kept complaining to my mechanic every month, replaced batteries each year thinking I had a power problem. I learned about the real problem because this last time it happened on 07/03/12, the help came from someone who knows about cars and he told me about the recall on the crank & cam sensors. I took the car to the nearest Nissan and, yes, that is exactly the problem with my car!. but they said because I didn't service and didn't buy the car from an authorized dealer and my car isn't on the "list" they won't fix it. The cost isn't the problem I told them, the fact the car came out of your factory defective should be your responsibility to correct it, never the less your responsibility to recall all units with the problem not just a few. I am taking the car to them to fix the problem right now and pay for the repair because I have a 4 months old baby and I don't want to be hit by another car when my car stops running in the middle of the street but I do want help and have them be responsible for reimbursing me on the cost of the repair and recall all and every single unit involved with this issue. Nissan corporate (yes, I called them too) will not take any responsibility on the case either.

My car began to shake uncontrollably and my check engine light started to flash. I've brought it into a shop 3X now and they can't seem to find the problem so my car has been sitting in my driveway since the incident. My oil is burning at an extreme rate. I only drive max. Maybe 20 miles in 2 days and keep having to put 2qts. Of oil in my car. It's smoking really bad too. I keep paying for labor when the problem hasn't been solved. I found the following on Ntb03-070C safety recall campaign -revised- 2002-2003 Nissan Altima, 2002-2004 Sentra; voluntary recall campaign engine exhaust pipe hanger pin and pre-catalyst for 2002-2003 model year Altima and 2002-2004 model year Sentra, there is a possibility that certain engine operating conditions may cause damage to the pre-catalyst. Material from inside a damaged pre-catalyst could enter the engine and result in increased oil consumption. If the engine oil level is not checked on a periodic basis and drops below the low level, and the driver continues to operate the vehicle ignoring noticeable engine noise, engine damage may occur which could result in a fire. I don't know what to do. I keep paying money, but no one seems to fix the problem and I need a car.

My camshaft position sensor, bank 1, was diagnosed by sears as needing be replaced. My service engine light went off is what first made me aware of this issue. I read online that it's a faulty part, which has been recalled for certain years/VIN numbers by Nissan. I contacted Nissan directly, and they told me that my particular VIN is not covered under the recall. It is a cheap plastic part, and the new/replacement ones are made of metal is what I'm reading in the numerous cases discussed online from fellow Altima owners who have experienced the same issue with these years of production.

Altima 4-cyl

  • 166,963 miles
I was driving on the highway, 60 mph, coming back from a friend's house when the car started shaking violently I felt like I was in a lot of danger so I got off the highway and came home through the streets, even though it was shaking a lot. While I was going home the engine felt so weak and sounded like a diesel truck. After research online I found out that many 02 and 03 Altima owners are experiencing the same problem because of the butterfly valve in the throttle body went into the engine, Nissan North America refuses to address the problems in the 2002 and 2003 models even though they have recalled the 04 and 05 models with the exact same engine in the 02 and 03 models!!!! please help the 02 and 03 Nissan Altima owners because Nissan North America is refusing to help even though they know the engine has major problems!

Altima 4-cyl

  • miles
Due to faulty cat converter which Nissan failed to replace the engine is burning oil excessively due to debris from cat converter going inside the engine. Roughly at around 100K miles car needs new cat converters and new engine block. This issue is very famous among 2002-2006 Altima and Nissan is well aware of this. The oil indicator fails to inform the driver of pretty much zero oil in engine and this creates a catastrophic damage to engine which can result in fire.
