We purchased a 2003 Nissan Altima, after making a stop on the way home, 3 hours away, the car would not restart. We were stationary in a residential parking lot. Had it towed to a certified Nissan dealership in northern Virginia and it was determined it was the crankshaft/camshaft positioning sensors. Nissan would not honor the recall because our Altima has the 3.5 V6. Apparently the recall is only for the 4cyl. Well guys, the sensors in the V6S don't work either. So after paying the $1,068.17 repair cost and multiple trips back and forth to northern Virginia (if you have ever been there you know traffic is horrible) we finally brought the car home. Bad business!!

Takata recall my car seems like it won't crank up or like it is not getting gas

- Huntsville, AL, USA

"takata recall". my complaint is that while driving my 2003 Nissan Altima, the engine stalls intermittently. I only have about 50K miles on the car and it has been well cared for. This is very dangerous as you can imagine. The code comes up P0335, but the mechanic believes it is a faulty crankshaft position sensor as well as circuitry issues involving the same part. Apparently, there has been a recall on the crankshaft position sensor for the 2003 Nissan Altima, however dealers are not willing to acknowledge this. I would like this investigated further, as I'm discovering upon further research this is a pandemic among 2003 Nissan Altima owners and an extreme safety hazard while driving. I was nearly rear ended at a stoplight a few weeks ago and while driving at a 45mph speed on a busy street where there were many cars around me.

Everything I have had to replace/repair on this car is linked to recalls, but Nissan is denying this & refusing to help. They said my vehicle was not part of any recalls but everything that's failing is related. It has died on me in the middle of highway traffic w/ my child in the car several times. This car is defective & no one from Nissan is concerned!!!! butterfly screw/valve issues, cam/crank shaft issues--related to engine cooling, high oil consumption; alternator failing; oil leaking

The floor boards rotted out, just found out about it, give it a few more months. I can become fred flintstone and start pushing my car around when the camshaft/crankshaft sensor goes out again. Both sensors have been replaced and still had not corrected the problem. Brought the car in today and was told there are no recalls for your car. That's interesting when you can't go anywhere and you are sitting at a light with traffic behind you. That's were meet the flintstones comes in, using foot power to move the car.

I have had my car shut off on me while driving down the road causing it hard to steer almost causing other cars to rear end me. Then the car wouldn't start. Every year I have had to buy a new cam shaft sensor since the install of the new engine that was put in by Nissan. There is a recall on the cam sensor but my car is not under that recall.

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.

Loss of all power while driving

My wife was driving our Nissan Altima with our kid when all of a sudden the car started to stutter and then it just stopped in the middle of the road. Luckily the car behind her did not hit her. She was able to start the car again after a few minutes and then was able to drive it home. After she reached home, I then took the car to a nearby auto shop when the car just stopped again in the middle of crossing an intersection. The steering wheel was stiff and it could not be turned. I tried to start the car but it wouldn't start. I waited for a few minutes and then I was able to start and drive the car. I turned on the hazard lights and then drove the car to the auto shop. The mechanic mentioned the cam shaft sensor was bad and upon searching online I found similar drivers mentioned the same issue and that there has been a recall on this. I have all the paper work from the mechanic as proof that this was the same problem as mentioned in this link. repairpal.com/nissian-crankshaft-and-camshaft-sensor-recall-492 I contacted Nissan Consumer Affairs and they claimed that there weren't any recalls. They weren't willing to admit this issue. It seems like they will act only when there is a serious injury or loss of life.

Loose power valve screws - while driving my 2003 Nissan Altima 2.5 S both on city streets and on the freeway, the vehicle arbitrarily ran super rough to the point of almost completely cutting off in middle of traffic lanes. One instance was particularly dangerous because I was making a left turn across traffic lanes, and the engine stalled in the middle of opposing traffic lanes and I was almost T-boned by oncoming cars. Finally the engine wouldn't start at all one day, so I had the car towed to the dealer, and they identified a problem with intake power valve screws that needed to be replaced at a significant price. I had to get the car towed once before, and the dealer diagnosed the problem as a defective camshaft position sensor, not covered by any recalls, but obviously a significant problem for 2003 Nissan Altima owners. After doing my own research, there seems to be a large number of owners of this same car experiencing the same power valve screw problem also. I also believe there is a recall on 2004 and 2005 Nissan Altima for this problem, which have the same engine as my car.

My Nissan Altima 2003 2.5 sl has been experiencing lot of vibrations and power lost while traveling on city streets and highways, the problem seems get worse once your exit the highway sitting at the light the car want idle. It seems like it wants to shut off. Now my engine check light comes on so I took the car to tire plus car care, they told me the ECM program is out dated and the code they read indicate new program update and possible catalytic converter problem, I took my car to have catalytic converter changed $400 dollars they cleared the engine check light and said this should take care of the vibration and engine idle problem, one week later engine check light came back on, problems of vibration has gotten worse. I decided to take the car to courtesy Nissan dealer had them to perform diagnoses service person told me the ECM was out dated so I paid $120 dollars to update ECM program, the service person told me the vibration is because maybe the throttle body (power valve screw) may be going bad and if power loss happen again I will need to replace the throttle body at my expense. Note: I have done some research and found Nissan North America (in their voluntary service campaign papers) refers to it as the power valve. There are small screws on the valve that come loose and get sucked into the engine. Even though the 2002 through the 2005 Altima 2.5S' all have the qr25de 2.5S engine (which is the exact same engine with the exact same problems), the manufacturer, in this case nna is able to loophole the laws concerning a recall. Like in my case and other people's cases, we have the 2002 and 2003 Altima that is experiencing this problem, but nna won't take care of it even though they are aware of it and currently have a vsc on the 2004 and 2005 models.

Car suddenly stops while your fmdriving at a low speed. Check engine comes on andturns vehicle off. This is very dangerous and I font understand why it hasnt been recalled. Most of the comments are said to be either the camshaft or crankshaft. They replaced the part and it was fine for 3 months and it ccontinues to do it. Im going to end up causing an accident and Nissan doesnt even care....
