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.

Altima 6-cyl

  • 160,000 miles


Car began to idle roughly and was hard to start. Replaced oxygen sensors which did not cure symptoms. Was told that the 2 pre-cats (catalytic converters) needed replaced. Motor mounts also recommended. Replaced and problem persisted. Hard to start, runs rough now shutting down while driving. Ran codes myself with obd-II tool and found crankshaft and camshaft position sensors to be faulty. I heard of a recall for this very issue; even described my symptoms exactly. Even though my year model and car was recalled the Nissan of fort worth service desk told me my VIN # was not covered. My car has the exact same engine as all of the other Nissan made in this year range and the same faulty crankshaft and camshaft sensors but for some unknown reason mine are not covered by this. How is this even possible. I have replaced a lot of pricey parts all which may have been avoided by replacing the sensors. Even if I had to pay for the crank and camshaft sensors it would not have been bad if I had not paid over $3000 in repairs to other stuff that may not have needed replacing.

In the past 2.5 years I've had to replace 2 coils on 2 different cylinders, and 2 different crankshaft position sensors as well. Each time it's cost me upwards of $300 each incident. A review of the internet website for complaints from Nissan drivers of the same vehicle make/model/year indicates that others have also run into these issues without any recompense. Some even had their cars stalling out while driving, which is obviously a safety concern. "luckily" (and note that I use the term in quotes), my experience has been that the engine starts running rough, feeling like on just 3 of its 4 cylinders, then the "service engine soon" light comes on. It was then always obvious something was really wrong. Q: why wasn't this a recall item for the Nissan engine? P.S. I have less than 60K miles on my car and it's in pristine condition and always garaged.

Altima 4-cyl

  • 105,000 miles
2.5L engine S model Nissan Altima. 2002-2003 has well documented blogs and complaints of excessive oil use. Causes are any thing to poor design valve seals to dust kick back from overheated catalytic convertor into piston/cylinder area causeing ring failures as well. This current vehicle has to been diagnoisised by a Nissan dealer. It burns 2 quarts of oil per 160miles. The dealer recommends a new engine and new catalytic convertor. The regional Nissan manager chris states Nissan will not assist in any way to replace/repair these items because we have not owned the vehicle long enough. The car is worth $3800. The engine +convertor+ labor is over the value of the car. Some one high up somewhere dropped the royal ball on recalling this engine.

Altima 6-cyl

  • 159,000 miles


Car stalled two times within 20 minutes when slowing car down to make a turn. Meineke and paul miller Nissan of fairfield, ct identified that parts 23731-al61A (crankshaft/camshaft sensor) and 23731-6J90B (camshaft position sensor) need to be replaced. These sensors were part a recall for the same make, year and model of car that I own. Nissan N.a. claims that my VIN was not a part of the recall. 630,000+ vehicles were affected by this recall but my vehicle does not apply. On line complaints suggests that the exact same complaint keeps recurring but Nissan has not expanded there VIN registry to include all cars that are affected. Spoke with Nissan N.a. case expediter who stated my vehicle VIN was not on the affected list although my complaint was the same as those vehicles on the list. Nissan representative would not tell me where my part was made and where the defective parts were in fact made. Claimed that this was internal Nissan information that they had no obligation to give me.

Altima 4-cyl

  • 105,000 miles
We purchased the vehicle from a private individual. It had 105000 miles on the odometer, it is a 2003 Nissan Altima with a 2.5L (4 cylinder engine) shortly after purchase.. we noticed a very foul smell coming from the exhaust and into the passenger cabin. Also the engine consumed 1 quart of oil per 50 to 60 miles. No exaggeration ! I discovered a recall on the Altima concerning it's precat/catalytic converter could over heat, break into pieces and some of the pieces could be sucked back into the engine, scoring the cyclinder walls and causing excessive oil consumption. I emailed Nissan with my concerns. They assigned a case # to my concern. They asked for a Nissan dealer to evaluate the problems and give them a formal diagnostic of the issues. The Altima had a new catalytic converter installed in 2007. A oil consumption test was done on the car and the oil topped off and we were told to come back in 250miles so they could check the oil. In 160miles we returned and there was no oil on the dip stick! also the check engine light was on and a code for "catalyst" problems was in the computer. This was all sent to Nissan via email. Now instead of a rep. Handling the issues.. they have sent it to a regional rep. And we are awaiting their "goodwill" decision. That year Altima and engine has repeat issues even after recall repair. Tpart of the recall states that if the owner does not check the oil often and ignores engine noises that it could result in a fire! supposedly a exhaust hanger catchs debris and causes the fire"?? lol who are they kidding"

Malfunction indicator light is on. Drove to a repair shop to get a diagnostic analysis on the engine. I was told the reason for the indicator light was because I had a bad crank sensor. There is a recall for that so, I called the dealership and they ran my VIN number and told me there was no recall for my car and I explained the situation to him they still wasn't going to fix it. Then I called the Nissan recall place and she said the same thing. So now what do I suppose to do now.

Altima 4-cyl

  • 151,000 miles
I had just bought my vehicle in March 2010 for $4200. A few weeks after I started to notice that the vehicle was burning through oil every few days. I took it to my mechanic and he stated it needed a tune up. A few days after the tune up I noticed it started to run rough on the highway on my way to work. While on the highway the car stopped running everything shut down, no power steering. I had to glide to the breakdown lane hoping and praying I would make it and not get hit. So I had the car towed to the mechanic who then told me that the motor was blown. I didn't have the money to fix it seeing as I had just bought the vehicle 6 months earlier. So I then parked the car in my driveway until I had the money to replace it($2000). Once I was able to replace the engine 2 months later the check engine light come on again. I take it back into the mechanic and he tells me its the radiator. I replace the radiator ($200). A few weeks later the check engine light comes on again. The mechanic tells me its the catalytic converter and that he's done atleast three Nissan in the past month with the same problem and that there is a recall and to contact Nissan. He also told me that if I to drive the vehicle like that it would blow the motor again because that is what caused it to blow initially. After taking it to a Nissan dealer they told me that there is not "open" recall on the catalytic converter just an ECM reset and the halogen light recall. They did tell me the catalytic gone due to a cylinder 2 misfire but that was not covered by them. I then called Nissan directly and they told me that there was a recall previous for the engine and catalytic converter but it was not an open recall and they were not allowed to send me that information. If I wanted that information I would have to go through car fax. This was from their upper management.

Driving legal speed on interstate highway 59 South from meridian ms to slidell Louisiana. Car started using oil every 20 miles. I have taken vehicle to Nissan dealer on 3 different occasions. It ws determined that the engine and catalytic converter is bad. I have contacted Nissan North America to ask for them to repair under recall #03V084000.

Altima 4WD 6-cyl

  • 168,365 miles
Was driving 45mph when the engine shut off, steering wheel got stiff, and I had to maneuver to safety. Tried repeatedly to turn on the car, but it didn't work. I came to a complete stop, waited a few minutes, and then the car turned on normally. I have a family of Nissan owners and this was the first incident of this ever happening. I just want Nissan to help fix this, or risk loosing a valued customer to another car brand. Considering infinity just lost 2 CEO's to other brands makes me (as a consumer) uncertain about this brands future.

Altima 4-cyl

  • 116,000 miles
On Jun 29, 2014 our family of four (along with my wife and 2 kids) were in this 2003 Nissan Altima driving on the expressway at around 55mph. All of a sudden, without any warning, the engine stopped. Pressing on the accelerator did not do anything. Cars were all over the expressway, zipping through at a high speeds. A very scary situation. Somehow, we were able to pull over to the side of the expressway without any incident, but it could have been very fatal to my entire family. Once pulled over to the side, I called my insurance co. To send us a tow truck. While I was placed on hold, after a few mins we were able to restart the car and were able to drive home. Next day, I called Nissan company and told them about my incident and they said there are no recalls on my car and they suggested that I take it to a mechanic. I took it to a mechanic and they ran diagnostic test and found out that cam shaft sensor was bad and they replaced it at my cost. I'm very disappointed with Nissan as to how my car is not part of recall even though the engine just cut out with out any warning putting my family at great danger (possibility of severe injuries or even death) and Nissan does not want to take responsibility.

Altima 4-cyl

  • 121,044 miles
In Nov 2013 the car would stall (engine dies) while driving. The car would not start sometimes and the check engine light came on. Vehicle was taken to a Nissan dealership where the oem was reprogrammed. I was also told the cam position sensor had an internal failure. The oem reprogramming was covered by a recall but not the sensor which was VIN specific, as told by Nissan. I replaced the sensor. This year the car has been jerking and would not start several times (seems the problem re-appears every summer). I again took the car for repairs and was told it is the crank and cam position sensor. I have again replaced the sensor and called Nissan. I was told my car is not covered by the recall as it is VIN specific.
