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.

I purchased a 2003 Nissan Altima with 106,000. As is no warranty. Within the first month it blew the head and needed a new engine which I paid for out of pocket. They supposedly replaced the enigine with a new crate engine once again the car lasted about 3 weeks before it was smoking so bad and will only drive at idle speed.. I dont think the place I bought it has a very good mechanic and I really would rather take it to a Nissan dealer.. but I dont want to pay for another engine I feel like ive already bought the car twice.

While at a red light, the car unknowingly stopped! I didn't even know until the light turned green and I attempted to pull off. I put the car in park and resterted the car with no issue. A couple days later the engine started a slight shake and each day the shake became more intense and the engine would shut off when driven for a while & while my feet is on the break the meter would jump from 0 to 2 and shut off wen it hit 0. also while attempting to pull off the car feels like it's stuck then it'll shoot off.

Multiple times while driving between 30-45 mph the vehicle has stalled and not produced full engine power when pushing on the accelerator. This has caused serious concern for the safety of my family and myself. Check engine light came on and I took the vehicle to Nissan service repair (August 2011, ~94K miles). Nissan ran diagnostics and stated that the circuit board for crank/cam sensors had failed. Paid $430 to replace crankshaft and cam/crank sensors. Fast forward to December 2012 (~110K miles) where I experienced the same exact issues along with reduced engine power when pressing on the accelerator. Another local mechanic detected that the cam/crank sensors needed to be replaced again. I did some research and found out about recall #03V455000, which describes the exact symptoms that I have been having. I called the Nissan service department that replaced the sensors in 2011 who said that my VIN wasn't included in the recall so I didn't qualify. After reading the complaints on this site for this specific year/make/model, it is beyond me how nothing hasn't been flagged about this being an issue. All these people are having the same problems (multiple times) yet they are told their VIN's don't qualify under the recall?? something is fishy there. Other complaints with the same exact issue include the following numbers: ODI id numbers: 10416743, 10384742,10370526,10342438,10332467, 10318898, 10318045, 10314479, 10283487, 10278805. Thank you for any assistance or light that can be shed on this issue.

Like many other complaints, my car stalled on highway at 70 mph speed and stalls at intersections and low speeds or will not start. I can't believe Nissan or NHTSA has not got serious about this issue. I checked your database and found following compliant numbers with same issue of Altima stalling due to crank or cam sensor failure. (ODI id numbers: 10416743, 10384742,10370526,10342438,10332467, 10318898, 10318045, 10314479, 10283487, 10278805, ..... and many more). I am lucky to be alive. I am sure there are my accidents and deaths that did not get reported due to this manufacturers defect. This is a very unsafe and dangerous problem that could lead to many deaths. I hope NHTSA looks into this and get it fixed.

My daughter was driving home from work in my 2003 Nissan Altima when the car suddenly stopped running, the steering wheel froze and she nearly ran off the road. Thank goodness there were no other cars coming and she was able to pull off the road with no incident. I pulled the codes and found it to be the P0335 (crankshaft position sensor) and P0725 (engine speed sensor). After searching the web, it appears there are many people with the same issue. I looked on the NHTSA website and found NHTSA campaign id number: 03V455000, Nissan recall no. R3022 that states exactly what did happen - the check engine light came on and the engine stopped without warning. The remedy is that a dealer replace the crankshaft position sensor. So, I called Nissan, found the other recall that is related to the sensor, took the car to the dealer (barely - I drove and the car stopped twice - again, lucky there was no crash). The dealer called and said he could not fix this recall because the sensor was bad. Now I have to go back and pickup the car and pray again that I don't have a crash coming home. Seems totally unreasonable that Nissan would have a recall for this exact problem - the crankshaft position sensor - for, among many others, 2002-2003 Altima and yet there are many people out there with these cars that Nissan won't fix. I was laid off and certainly cannot afford a $300 fix for a $40 part so we will have to drive this death car until I can figure out how to get it fixed. And pray every time I get in it that we don't end crashing the car, hurting myself, my young twins, my older daughter or anyone else on the road. This is a severely dangerous issue and Nissan should replace all cars - not just a select few.

Recently while driving my ses light came on. I took my vehicle to the nearest service center and had them read the codes which were 0725 engine speed sensor and 0335 crank shaft position sensor. Upon looking into the problem I found that this is a common problem with many Nissan owners, particularly the Altima models. Nissan has issued a recall to reprogram the ECM free however this does not solve the problem. The problem is the crankshaft sensor, and Nissan should be responsible for replacing the defective part (the part has been modified from plastic to metal because of other complaints however they will not cover the replacement, ridiculous!) this is particularly dangerous due to the fact that I can cause the car to stall randomly while driving, which has happened to me on two occasions (luckily not in heavy traffic of on the highway! but it has happened in more serious situations to others).

The contact owns a 2003 Nissan Altima. The contact experienced unintended acceleration in the vehicle. While traveling less than 2 mph, the contact attempted to stop the vehicle. When the vehicle came to a complete stop, it suddenly lunged forward at high speeds. The vehicle crashed into a tree. The contact was uninjured. The vehicle was towed to the nearest Nissan dealer for repair, which was covered under his insurance. The current and failure mileages were less than 33,094.

2003 Nissan Altima. Idle fluctuation from 1000 to 2000 RPM. Also, automobile surges from 1500 to 2000 while driving. While in automatic mode 1 it will buck forward. The auto in my opinion isn't safe I feel there should be a recall. The check engine light indicates high idle. We are in the process of having the car repaired.

On several instances the engine cuts off while driving. Major safety concern. Eventually, the check engine light came on. Took vehicle to dealer, and dealer informed me of recall campaign to reprogram the ECM. Also, they found error codes P0725 and P0335. They told me that I had to replace my crank shaft position sensor (at my cost -- this was not part of the recall). After the dealer completed the recall work, the car still stalled that very day on the way home. Took the car to my neighborhood mechanic who replaced the crankshaft position sensor. Check engine light was cleared by mechanic and has not lit up again, however, the vehicle has stalled while driving again. This sounds very similar to the symptoms which led to the recall of the 2002 Nissan Altima's. my car was manufactured in December 2002, but was not included in the 2002 recall. The 2003 recall only consisted of reprogramming the ECM -- which did not solve the problem. This is a serious safety concern as the vehicle still cuts out at random times in moving traffic. Please investigate -- this is similar to hundreds of other complaints under 2003 Nissan Altima's that I found reading through the complaints on this website -- please connect the dots and make Nissan own up to the problem.

Recalls on 2003 Nissan Altima concerning crank angle sensors and ECM, engine computer, received. Took it to a Nissan dealer, and they reprogrammed the ECM. They said this would fix my problem. 2 days later light was back on, and car continued to cut-off just as the recall letter stated it would do. Took car back to Nissan, and they refused to honor they recall, and have asked me to pay for it, and then they will investigate and will send me a refund for repairs. Over $200 for repairs. Advised them of their recall letter that I received only to say they were sorry. Check engine light is still on, car cuts off while driving are, and while just sitting still. It continued to jerk or drive like it was skipping, and they claimed it was the crank angle sensor that needed to be replaced, same as recall.

Courtesy copy re defective 2003 Nissan Altima. She is seeking reimbursement from Nissan. The vehicle stalled weather the vehicle was acceleration from a stop or while driving at various speeds. The check engine light illuminated the vehicle was taken to a dealer who indicated that the vehicle needed the crank case replaced, throttle sensor adjusted, fuel injection flushed, power steering flushed, and brake fluid flushed. The consumer did some research and found recall 06V242000 in reference to faulty engine crank angle sensor. The consumer vehicle fell within the range of the recall but the consumer was told by the dealer that the vehicle was not included in the recall. Therefore the consumer had to pay for the replacement of the sensor. Several months later the check engine light illuminated again. The vehicle was taken to another dealer who checked the recalls. The dealer replaced a faulty chamber. The faulty chamber resulted in a throttle chamber replacement.

1. car stalled and once I held the gas pedal down and was able to hold the key over and crank the engine a huge puff of black smoke came out of the car and it seemed to run fine, although the service engine light came on. It eventually went away after a week or so. 2) a week or so later I started the car, it turned over fine but had no power, it simply would not go. It did not even realize I was pushing on the accelerator. 3) I removed the key from the ignition in frustration and then tried again. The second time the car worked fine. It revved when I put my foot on the gas pedal and then took off just fine. 4) this began to be a more common occurrence and if I took the key out or waited a few minutes it would straighten up. 5) not now! the car won't move forward. And now it is even starting to stall out and flood. 6) now the battery even seems to be running down. This has all taken place in the matter of about the past 5 weeks and now it won't move forward or run at all.

The throttle body control operated poorly. The vehicle started but it did not accelerate. The vehicle is currently at the dealership, they did not know why this was happening. The problem started in may, they were able to jiggle the throttle, and it would start working, but it progressively got worse. Currently, it needs to be replaced. Consumer stated there were four on back order at the dealership.
