Have YOU gotten "Special Assistance Beyond Warranty Period"?! Please tell me your experiences with this!

My '99 Maxima SE V6, suddenly started to misfire this Autumn. I checked the code at AutoZone, and it came up with code: 1320. When I took it to the Nissan Dealership they said it was the sparkplugs. I was surprised, as I have only 36,000 miles on the car, and my warranty book says that the Platinum sparkplugs should last 60,000 miles.

This did NOT solve the problem, so I took it to another Dealership. They said it was the Ignition Coils. This was a costly procedure!

My question is: should this be covered under Nissan's "Special Assistance Beyond Warranty Period"? Please let me know if you have also encountered this problem.

Nissan has a service bulletin for this problem with '99 Maxima's--so I assume that others have had this same problem.

PLEASE share your insight, experience and advice! Thank you VERY much!

 

After the warranty period, I basically had to pay for every little thing...including the TSBs. So I really don't know what this "special assistance beyong warranty period" covers.
