This was not an accident but a manufacturer fault. The engine is burning excessive amounts of oil to the tune of 1 qt per 200 miles.

- faulty intake valve timing control solenoid valve - intake valve timing control solenoid valve harness is open or shorted - intake valve timing control solenoid valve circuit poor electrical connection - faulty camshaft position sensor - camshaft position sensor harness is open or shorted - camshaft position sensor circuit poor electrical connection - faulty crankshaft position sensor (pos) since the intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code. When there is a gap between angle of target and phase-control angle degree, the valve will stop working and the ECM will trigger the P0021 code. Possible symptoms - engine light on (or service engine soon warning light)- lack/loss of power- engine rough idle P0021 Nissan description this mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve. The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends on/off pulse duty signals to the intake valve timing control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range. The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When on and off pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position.

If you google 2002 Nissan Altima problems you will see hundreds if not thousands of people complaining from about 60K to 100K about a design flaw of having the pre catalytic converter too close to the exhaust valves. The pre-cat was found to be a problem of breaking down the metals inside and causing them to be sucked into the engine and ruining the piston rings and ultimately blowing the engine. Nissan had said my car was not part of that recall but low and behold I experience the same symptoms. 2 quarts a week oil consumption, smoke coming out of the tail pipe, no heat until about 4K RPM. Many calls and complaints went upon deaf ears. Why is it so hard for them to see that they missed some on this recall. Many with this engine like Sentra's with the 2.5 engine have the same problem. Some have replaced the pre-cat just to have it fail again and ruin the engine after repairs.

- Staten Island, NY, USA

This car almost killed me. While I was driving in the traffic, the engine suddenly died, there are no power, no steering, no brake, and will not start again this time. The engine has been eating oil and coolant like crazy.

- Winchester, KY, USA

Engine light continues to come on after replacement of spark plugs and wires. Car shakes and stalls. Idles roughly and will not "go" upon acceleration. Have been given the run around and recently viewed recalls online for faulty engine and cooling system. I have never received notification that a recall was issued. Problem has persisted and only gotten worse for over 6 months.

- Louisville, KY, USA

Problems: Service engine soon light, no start condition, reduced engine power, stopped running during vehicle operation. Car was parked and when started would not go over 15000 RPM - would not back out of the parking space. After several attempts at restarting it I was able to drive it to my local mechanic for him to check why the service engine soon light was on. Code he received did not give him any information so he turned the light off and I continued driving the car. On June 26, 2014 the engine stalled as I pulled up to a stop light. After putting the car in park and turning on my emergency blinkers it began running again. No service engine soon light came on. The next day the car failed to start. After several attempts it started and this has happened multiple times since then. A recall notice for all of these specific problems had been issued in December of 2003.for 2002 Altima manufactured between June 2001 and June 2002. My Altima was manufactured in October 2001 and I purchased it in November 2001. I was told by Nissan when I called on June 27,2014 that my vehicle was not included in that recall even though all of the consequences of the recall were documented on my car. I did receive a recall notice in February of 2009 at which time the local dealer reprogrammed the ECM (R0712). Not sure that worked because in July 2010 the service engine soon light came on - took it to repair shop which replaced the crank position sensor (which could have been defective also since all of these problems are occurring). I paid out of pocket for the same thing others are getting repaired by Nissan for free. Recall no. R3022 and 03V-455 describe these problems.

The catalytic converter below threshold light came on then afterwards it got sucked up into engine and caused the engine to burn oil ridiculously fast causing me to buy hundreds of dollars in oil and oil changes. Now the engine doesn't run right it seems and needs to replaced among with catalytic converter.

- Pocatello, ID, USA

Nissan Altima 2.5 auto transmission. Nearly killed me. Car suddenly went to 20 mph on the interstate in heavy traffic with 18-wheel 30 ton vehicle behind me. Burns oil like crazy. Put in better synthetic oil, burns faster. Had the car die on the interstate at 75mph right in front of an 18-wheeler. Could have died. Could have been killed by the Nissan corporation. Know any good lawyers? this is really dangerous, Nissan should recall and replace this engine. Replaced catalytic converter, O2 sensor, pre-catalytic converter, spark plugs, some other related stuff. Burns oil even faster than before. Completely ran out of oil in 300 miles. I am trying 10-40 oil to see if the oil burning problem will slow down. Car only has 125000 miles on it. Complete pos. Never buy a Nissan, I never will again. This was my first, only 125K on it. I am used to selling perfectly good Ford and vws at 250K miles. On the internet most people fail the pre-cat and catalytic converter by 95000 miles, then overheat and blow the entire engine. Cars stopping suddenly at 75 miles an hour are going to kill people. Since Nissan is well aware, this is pre-meditated murder. Other symptoms: No power, no acceleration, no response by Nissan dealer. Nissan "service" is a joke. Never take a car to Nissan for repairs. Unrelated sign of really really bad engineering: Paint is falling off car. Never had that happen to a car before, I have a 14 year old Ford with 240K and the original paint job, even though it is not garaged.

- Pasadena, CA, USA

I bought my car brand new in 2002 and there was a series of recalls for different items. I noticed that the engine was not keeping a clean idle after about 69,000 miles in 2010 so I had to have it computer tested due to maintain lights etc. I got P0420 code for catalytic converter not working properly. I took the car to the star Nissan dealer where I bought it, and the service writer told me there was no issues with the cat or pre cat which was a lie! since that time I have been losing about 2 1/2 quarts of oil every couple of weeks and then the engine quit on me and now I am told it is a extremely common problem with no answer and that I need a new engine!!! Nissan just told me oh well!~ is there anything I can do about this I have seen thousands of exactly the same problem from other consumers? thank you for your reply.

- Oceanside , CA, USA

My car keeps consuming oil 2qts every couple hundred miles. This is outrageous. I've been told that I need to replace my engine and that this is a common problem with the year and the vehicle I have. Not only this but also my catalytic converter needs to be replaced!!! please help!!
