This experience began about six months ago when my windows began to stop working intermittently. When pressure was applied to the door, the windows would work, but this trick soon began to lose its effect and the windows stopped working completely. When I had called up Nissan Marlborough initially, I had spoken to a receptionist in Service who said that my part was not covered, and to find out I would have to commit to some payment. As a purchaser of an extended warranty, I ignored her and drove around angrier than heck that my new-ish car was having old car problems.
Upon receipt of a recall notice from Nissan, I had brought the car in and fought my way to a technician on the phone. Once they were on the line, I was able to find out a trove of information about my policy, including the fact that my window malfunctions were covered. When that problem was solved, it was as easy as bringing the car in and having the work done, and picking it up at the end of the day. Oil changes are about $5 more, but they can run diagnostics on your Nissan like a small shop can't.
Main take away - make sure to talk to the technicians about any car problems and how it relates to your policy. Once that hurdle is overcome, they are a very knowledgeable and skillful service shop that costs a little more than Johnny Mechanic, but is usually worth the cost
