when i took mine in, i purposely waited a few days for the springlifts to settle in and didnt access the cargo area for those few days...
so the day i took it in i let the service manager try and sure enough it didnt pop open on the first or second attempt, however the third and fourth attempts were successful by him...i thought he was going to send me on my way lol
then he said hold on a minute and we walked over to another 370z with a sports package on the lot and he popped that hatch and it popped the first time and everytime after that, so he swapped the springlifts from that z to mine and put mine on the new z...i thought well ok ill give it the benefit of the doubt...so he puts them on my z and sure enough they worked 3 times in a row, so i thought what the heck!
i left the dealer drove home parked in the garage and thought let me test it...
nope it didnt open! i was mad at that point, but not at the service manager...
i immidiately called him and told him about it and he said ill take care of it. he opened a wokr order and got the parts manager to order the longer ones and ive not had a problem since! pops first time everytime. and i didnt even buy my z from this nissan dealer!
