I stopped by the dealer for my license plates today, and told them about the problem with new part numbers in hand..... the service advisor just wrote them down and agreed to call me in a few days when they come in. He didn't even confirm the problem :)

Which one?

Ancira. that is where I bought mine.

Nice to see someone else from SA here

Every once in awhile I will have to hit the button twice. I thought it was just me not hitting the latch button correctly but I guess there's an actual issue here. Hmm

Update:
 

I went to the Nissan dealer today and spoke with the Service Manager. I explain to him the issue I was having and asked him to take a look at my trunk and try to open it for himself. The first two attempts he made trying to open my hatch resulted in double depressing the hatch release button as well as lifting up on the hatch as well.

I had printed the work ticket that vipor uploaded here and gave it to him while I was there. I explained to him that it was a bigger issue than just my z, and told him about this thread and the 350z stuck hatch thread as well. He said that no one with 350z's ever came to him complaining of the hatch not opening properly, as well as the 370z'ers thus far. I thought that was odd considering the sheer amount of people in both ours and the 350z forum that are having the trunk release issue.

After his first two initial attempts, the hatch opened flawlessly there after. So he retrieved a key fob for a blue 370z on the lot and tested the hatch, and no issues with it at all, the hatch popped open the first time and everytime there after. So he decided to take the spring lifts from that z and swapped them with mine. It seemed to work! I was supprised, but still in disbelief that it would remedy the situation long term.

The service manager gave me his business card and extension, he said give it a few days and call me if it continues to be a problem. I thought to myself sure why not, it seemed to be working fine. I drove straight home, it took about 10 minutes to get to the house. I pulled in the garage, got out and was about to go inside the house and thought what the heck i'm going to give it a go and see what happens.

Guess what happened! thats right it did not open on th first attempt. Not only did it not open on the first attempt, it did not open on the second or third attempt either! However, on the fourth attempt and every attempt there after it opened flawlessly. So I immidiately called the service manager back and explained what had just happened. He then asked me to re verify the part number on the ticket and said he would call me as soon as the new spring lifts came in.

So I shall wait and hope these new spring lifts solve the issue at hand once and for all...

My dealer in Brooklyn, NY says the following:

84415-CD71A belongs to the 350Z
84415-1EA0A belongs to 370z
84415-1EA1E belongs to 370Z Nismo

I guess the 84415-CD71A's are longer than the others, and still fit a 370Z even though they are meant for the 350z?

Vipor do you have a side by side picture of the original lift springs you had and the new CD71a's you got? are they longer?

the 71A looks to be the same as the 715...look in vipors album and youll see the 71A's on his trunklid...

so that makes them a good half inch longer...

Wow! I had forgotten that I also had this problem on the '85 Z I had back in the day (the shocks not holding up the hatch after a year or two of ownership). Not sure what it means that this problem continued through a few generations of the car (at least once!).

I need the dealer to take a look at mine also, same story won't open or release at the first attempt once open it opens everytime!

my hatch springs are like Sex Panther......60% of the time, they work every time.

my new springs should arrive at the dealer next week :)

Have the same problem but thought it was because I had put on the NISMO Spoiler. So maybe I need the NISMO Springs.

Had my springs replaced with the new part number under warranty as well as a new center piece for the steering wheel (new airbag, etc) to replace a very slight flaw in the center cap of the steering wheel. Easy Peasy - no fuss no muss. Surprised actualy....

I'll get a pic or two of a stock spring at the meet today and do a side-by-side chop of it. It's probably 3/4" longer, not sure exactly.
