Just bought my 2012 Nismo and I have to use the "double click" method to make it open... wth?

I called the dealer and as my car is out of warranty now, they wont fix it for free. Parts are about $42/pc and I would need two of them plus they charge half hour labor....This aint cool as Nissan should take care of this just like any other recalls....

I gotta look around for a DIY on the penny trick if it works out...

Did you try my solution? The post is 2 above yours

The "penny trick" is very easy to do. Just give the units a quarter turn and they fall out. Peel the rubber boot off of the mount and stick the penny in the bottom of the boot (I used a nickel). Slip the boot + coin back on the mount and re-install. Voila! You may need to add coins in different combos (eg, two pennies or a penny plus a nickel) to get just the right push from the spring.

For me, it made things better but it still didn't open every time so I had the dealer replace them with the stronger ones (I was still under warranty).

It's not quite as easy to do but DE.50's hatch weight removal trick will probably help (see link in his post above).

That TSB looks like it only applies to '09 models but I definitely have this issue on my '11. Won't open at all without pressing the button and lifting at the same time. It's still got a bit of warranty left, will they cover the fix?

this happens often in cold weather to me, but not in warm weather. not too bothersome imo.

If you can't get them upgraded under warranty, you can buy your own and DIY the swap. Very easy job; no tools required.

Or use the "nickel in the boot" trick (several threads about that on this site). I did that while waiting for the dealer to get parts and it worked quite well.

I used DE's DIY which fixed the problem but I also put in couple of pennies just in case. Pain in the *** when you have **** in one hand and hatch doesn't open

I used two penny's (two on each side) on my 2010 Z; just bought a 2014 Touring model and have not experienced any issues yet but it is still early. One would think after four years they would have fixed this issue already.

wow - found out this was a known issue just yesterday while sitting at the dealership killing time during an oil change (past warranty at 107K miles). I used 4 nickels (2 on each side) and now my trunk pops on one click. I owe someone here $60... thank you!!!

same issue here back to not opening for like 4 "clicks"

e-mailed nissan we shall see what they reply :P i really dont like the idea of the penny trick... not sure the hatch will seal as well years down the road

Shouldn't be a problem. The upgraded buttons are a little longer and a little stronger than the originals. About as strong as the penny/nickle trick makes the originals.
