I had the same problem everyone else is describing. After reviewing your post i decided to tackle the problem on my own. Turns out it paid off. It only costed me $10 for the ring and gasket for the Engine Oil Cooler and an Oil Change. It is not hard to do it yourself so dont spend hundreds of dollars on an easy fix.
i got the same leak, started as a drip now its a quart a wekk, rediculous.. NISSAN stand up and recall this, how do we qualify for recall status, please refer link to make official complaint to NISSAN
begin leaking oil slowly then progressed to severely. Over $700 to fix. This was due to the oil coolant housing and had no gasket. The repair shop got the part from the dealer who told them that this was the 10th one recently. This should be a recall item.

My leak began as a nothing leak. I thought it was just from running the air conditioner and within 2 weeks I had huge puddles under my car. Took it to the Nissan Dealership and they said the extended warranty ran out and I was 11,000 miles over it. They said my front oil cooler is bad and it was going to cost me a little over $1200.00 to fix it. I have only 71,000 miles on the car. They said this is NOT a common problem, but researching it on the internet I found that it is common. Nissan is just sucking money out of peoples pockets and selling crappy cars that will tank on you before you reach 100,000 miles. If this many people are having the same issue recall the stupid things and fix them. Come on Nissan!!! Stop being cheap and start taking pride in your work and products. I'm getting rid of the car and will be getting a honda or something. At this point the bus is better than anything Nissan would make. Oh, and let's not forget...The customer service at the Dealership was TERRIBLE! These people are rude and insulting. I'm done with Nissan

Noticed a small leak after an oil change which has since turned into a quart a week leak. Have yet to fix it because they say the oil cooler needs to be replaced at $700 I just don't have the money right this moment. I have been researching this and find that it is a common problem with this car, should make a recall.

I have had the same massive oil leak in our 3.5L 2004 Nissan Altima. I was able to fix it very easily (just a couple more steps more than an oil change). Please don't pay a dealer $+700 for this repair. That is a rip off. I have put a video together on how to do this repair. It is available on www.YouTube.com at:

My 2008 nissan altima i paid 17thousand plus for brand new has the oil leak where the oil is supposed cool down, The job will cost me around 800 dollars, was told this cooler is behind the motor and the motor has to be moved to fix this oil leak. so dissapointed in nissan, yes this should be recalled. single mother no warranty hard to find a good and honest mechanic!!
I have an engine oil cooler leak where its made togeather. only offer gasket for housing to block, not for 2 halves of assembely. Have seen several in the past. poor design on Nissan's part. $320.00 for parts alone. Every one i've seen so for have been less than 100k miles. Nissan should do a campagne, or prefferably a recall, as this can lead to an engine failure due to major oil leak suddenly.

My 2.5L Altima had an oil cooler leak too. After paying $300 for a replacement and installing it myself I found that on the old oil cooler the 4 bolts on the cooler plate were a little loose. Maybe just tightening them would have fixed the problem leak. I have since also found that you can get the rubber gasket for the 2 halves of the cooler Nissan Part Number is 21304-JA01B. So this problem can really be fixed for less then $15 dollars in parts! Just 2 gaskets!

One week after I had gotten an oil change, I noticed the dip stick was reading oil at the minimum required level.
Took it back to the Nissan dealer and found out it's a bad engine Oil cooler. Luckily they are replacing it through the warranty so no charge to me.
This should be a national recall. The guys at the dealer have seen this issue a number of times already.
