I noticed my car leaking oil by the right wheel area. The dealership told me this problem was my oil cooler at a price of $271.00. This is the second time this problem has happen to me within a 2 years.

Noticed oil leaking on driveway close to passenger-side wheel, had leak diagnosed/inspected by local repair shop. Was told it was the oil cooler gasket that needed to be replaced. Was quoted high price to replace a $5 part. Will be fixing it myself after ordering part and doing research on the problem.

My car would leak alot of oil so I had a mechanic look into it and according to him the oil cooler was cracked and leaking oil. He said usually these parts dont ever have to be replaced unless its defective. =(

I recently bought a 2007 maxima, after a couple months I noticed an oil leak. I'm having a tech at my job work on it, now that I see this is a common problem I'll have to be more prepared.

I noticed a puddle of oil. I took it to the dealership. They had diagnosed the problem as a Oil cooler seal leak.
The car is leaking oil when started by oil filter, The dealership says they believe it to be the o ring at filter housing, How do you replace the o ring.

DC OFF light would randomly come on while drivingand there would be a sound similar to that of a bazooka @ the same time the light came on . then the car would seem to get stuck in some low gear with minimal power/ no git up n go & usually stall out or die. I took it to the dealership. They found an oil leak that caused damage to my car . but the cause of the light,stall issue was cam shaft sensor bank 1. They fixed it. That cost over a grand . a couple months later I was having the same issues this time it was bank 2, and another $500 to replace bank 2 and repair more damage from oil leak. So is this part of a recall since many maximas have the same issue? Wouldn't the Nissan dealership recognize if it is part of a recall. I feel like the mechanics portrayed this whole thing like it wasn't a typical problem with maximas. So I'd end up back in the shop with my car spending more $.
