Audio Out of Sync - Why and How to Correct

Question

I nested two 90 minute clips from 2 separate cameras which were both shot in AVCHD. I am using Premiere CS 5.5 . As a former FCP editor, whenever audio went out of sync, a message in FCP came up immediately and told you the audio was out of sync and it was an easy fix. How come Premiere is minus such an important feature?
I shoot stage productions where there may be music but no dialogue so chercking sync becomes rather difficult. After finishing a 2 hour video, I found the audio was out of sync in the nested sequences. Is there any way to auto resync the audio automatically?
Seems to me that Premiere Pro is a sub Pro App if simple audio sync is so hard to maintain in nested sequences. Makes nesting a sequence a waste of time if you have to redo the edit as a reslut of audio out of sync.

Hello Everyone,
Has anyone found a solution to this BUG?
This happens to me all the time with Adobe Premier CS6.
It is an obvious Software BUG that needs to be corrected. I am a TV show editor.
I have had this happen to me 4 different times. You don't have to do anything special. The video with sound runs perfectly with any other product on your computer..but goes out of sync in Premier. I have tried cleaning up the Media Cache .cfa and .pek waveforms. No joy. I have tried relinking the media. No joy. I have tried moving the project and renaming and relinking. No joy. Rendering No joy. Setting the media cache to local area. No joy.
If this had happened to me just once, I would say, I have done something wrong. It has happened now in 4 different projects on four different shows. I have produced and released over 100 shows to TV.
I have checked everything, I have reloaded footage off camera. I have checked and bought new cables. I have checked codecs, frame rates, loaded into other products. All fine. I just wish Adobe engineers would do this same type of debugging of their software.
I use to work for Hewlett Packard Software division.  We were taught to alfa test, beta test and not release until bug rates
were at certain levels. Some bugs just have get through or you never get to release. But this bug really hits your productivity in a major way. You have to resync BY HAND each cut... all your sound after hours and days and weeks of getting it perfect. Then in a split second. FFFFDDDDDDDDD
I have been editing with Premier for 6 years.... It only seems to be since I have upgraded to CS6.  And I have to re-link by hand to correct the problem.  I sync on electronic clapper board number and sound - almost impossibe not to sync. I will be working away happily, cut out some footage go to my next grab..BANG out of sync. That simple.
All I know is that it happens and for ADOBE to really be a true professional editing suite in the the TV/Movie world.... This is just not on. By any chance have they released a patch or bug fix to repair this. I have spent over 3 weeks edting a television show again .......needing to go to air in less than three weeks and all of a sudden between one cut and delete.. the sound is out of sync across the whole interview. JUST NOT ON. I have spent 4 hours now..none productive hours trying to resync the sound, find solutions on the website via forums. Some ideas have been really good and I have tried them. None have worked. Still unsynced. Almost completed show I now have to re-sync by hand. At this point, I am thinking FCP is looking good. I cannot stand this loss of productivity and time. 
This is not the only forum complaining about this..that should tell you something.
