Simple engine heat appears to disintegrate the pre-catalytic converter part on a 2002 Nissan Altima 2.5L engine. The engine sucks in the broken parts, which then damage the engine, requiring that the engine be replaced.

My car was serviced for a recall issue in 3/09 by the manufacturer. In August of 09, my car began to hesitate when starting, there was loss of power and hesitation during operation, soon afterwards the check engine light came on and finally the car failed to start. I brought it in to a local service center and they diagnosed that the crank position sensor and the camshaft sensors needed to be replaced. I was advised to bring the car into the dealer for additional servicing when I called Nissan Consumer Affairs. I opened a claim for reimbursement for the cost of the parts that were replaced that were supposed to be part of the recall work, but Nissan is saying that the parts that I had installed had nothing to do with the recall campaign.

Internal oil leak in 2002 Nissan Altima.

2002 Nissan Altima - engine defect. The engine nearly caught on fire because the oil was burning so much that there was no oil in the engine after a few miles! first there was a problem with the heating/cooling, check engine light came on, white smoke from the engine. Had each problem addressed at mechanic but problem was never fixed because the source was in the engine itself - a Nissan defect. Now I "need a new engine" because the source of the problem is the head gasket. My mechanic has seen 2 other 2002 Nissan Altima with the same problem. It was a defect in the original engine and it is dangerous if you do not catch it and replace the engine, due to such fast oil loss and an overheated engine! scary! the car only has 100K miles!! the car is not drivable now and I am seeing hundreds of other complaints of the exact same nature online with some fires already started. Yikes!

I bought my 2002 2.5 Nissan 72K four days ago. A day after I bought it, the service engine light came on. There is excessive oil consumption. I put oil in, and a few miles later I need to add more. I haven't changed anything yet, simply because I can't afford it. Nissan needs to take responsibility. I will tell everyone I know to never buy a Nissan. I am never buying a Nissan again. I've read numerous posts by people who have the same exact problems.

I own a 2002 Nissan Altima, I have to put a quart of oil in this car every 50 miles, from wha T I have found on the internet this is a very common problem, that Nissan knows about and refuses to admit to the public this is a defect in the motor, that the recall will cost the company to much in repairs. We are a family on a fixed income and can't afford the $6000 for repairs on this car. Nissan asks so much for these cars they should stand behind their products and repair this defect!!!!
