Radiator problems of the 2008 Mazda Tribute

Took the vehicle to the local firestone store for service to have the transmission fluid changed and flushed and they told me that the transmission cooler was leaking and this was a common problem with the 2008 Mazda Tribute and Ford escort and the only way to fix it was to replace the entire radiator because they were built into the same part. They told me $550 min. To replace. I then did some online research and went to the local Mazda dealer. They said it was a common problem and that Mazda had a program to fix this but the date was up and that there was nothing to do but pay to fix it. The Mazda dealer said $1100 to fix it. I went nuts and told them this was a rip-off. They said they would call Mazda to see if they would do anything to help with the cost since this was a known problem and there was a program to fix it for customers. They call back last Thursday to tell me that Mazda was not interested in helping in anyway and rejected the request. I told them this would make the decision for me on buying a fourth Mazda. I'm a repeat customer and they didn't even ask that information prior to making a decision. The is a bad problem with these vehicles and Mazda needs to step up and fix it!!!.
