NHTSA Complaint #11532397 — 2006 HYUNDAI AZERA

The vehicle has a random, chronic no start issue. Everything appears to be working normally, and you will turn the key with no crank. All the dashboard lights work, everything is as normal except it wont turn over. The dealer will not help. They refuse to even attempt replacing parts with my approval, just to try to rule things out. Due to my own investigation into the problem, we have successfully replaced the transmission inhibitor switch twice with good results. That switch will not allow the engine to crank if the car thinks the transmission is not in park. The first time the repair worked for 1 year, and the second time 6-8 months. I'm having the problem again, not sure where to turn for help. Dealer is useless, local shops have no better ideas than I do.
