Hi. My sentra is 2008 with 50.000Km. Last couple of week I notice a noise may be from engine or transmission related. I want to know if any one has already experience with this kind of problem

Depends on the noise... 50,000km.. it may be heat shields or it may be engine related... but we'd need more info...

Here are some of my issues including gaps in the trunk that were not sealed and leaked, and a fuel pump that was bad in the first couple years...

crank pos sensor goes bad and screws with the car.. stalls happen or general freaky occurrences, sometimes the car still runs other times not...

You are SOL if you are in Canada and the warranty expired.. this is a recall and they will replace the sensor if you are still under warranty.

I had my car die because of the CPS, luckily I was still under warranty.

The Pre-Catalytic converter on the exhaust manifold fails and particles get sucked into the engine... this eventually will toast your engine too... again if under warranty... you're ok.. otherwise SOL.

Nissan Canada is only required to notify of recalls, they don't actually have to fix them if you are past warranty even if you have next to no miles.

Butterfly valve screws on the intake come loose and fall into the engine... sometimes both screws come out and the valve plate falls into the top of the engine...

My 2002 SE-R Spec-V with only 80,000 or so kilometers on the 2.5 engine had the pre-cat problem.. so it began burning a little more oil...
but not excessively yet at that point...

Then the butterfly valve screw fell in to the engine and took it out..

I don't race my car nor do I red-line it and I change the oil every 5000km (sometimes sooner) with nissan oil filters and mobil-1 synth oil.

The engine should not die this soon even if someone beat the living crap out of the car....

I now have to come up with $6,000 or more dollars to get the engine replaced on a car that is only worth about 7 or 8 thousand...

Nissan Canada refuses to even help a little with this... their attitude is... "too bad.. you bought a Nissan... who cares if no miles are on the car it is just past the emissions control warranty... so... suck on that!"

Needless to say with all the recalls and engine issues and worst of all... Nissan Canada's hatred of their customers, I will never be buying nissan again.
