Owners/service Manual problems of the 2009 Jeep Patriot

My Jeep came with a lifetime powertrain warranty at the time I purchased the Jeep in April 2009. I was verbally told at the time of purchase to have the transmission checked before 50,000 miles. I have taken my Jeep into a local dealership a few times over the last few years to have minor things repaired and for normal maintenance. At those times I asked the dealership to check the transmission so I could comply with the warranty. I took my Jeep to the dealership again on 11/12/14 to get a minor problem fixed and I was told that my lifetime powertrain warranty had expired. I was told that since I did not bring my Jeep into the dealership on the 5 year anniversary of purchase (April 2009 - April 2014) to have the transmission inspected, that I failed to comply with the terms of my warranty. I was not aware that I was required to bring my Jeep into the dealership in April 2014 for the inspection. I was told that I could have it inspected anytime before 50,000 miles, which I did multiple times. I called Chrysler and was told that they should have sent me a notice by mail. I never got such a notice. Chrysler failed to properly notify me ahead of time to have my transmission inspected before April 2014. Chrysler told me that it was all my fault for not thoroughly reading my owners manual. They denied having any responsibility in this. According to Chrysler, it is not their responsibility to notify their customers about such things. It is the responsibility of the customer to read through the owners manual and remember to schedule service 5 years in the future. I am upset with Chrysler over this. Now my Jeep does not have any warranty on the powertrain. Chrysler has no concern for customer service. Only about making and saving money at the cost of the consumer. By cancelling my warranty, they avoided having to pay for any powertrain services I may have in the future.
