I’m confused about the Z03 warranty enhancemen program for the 3rd gen IPM. It looks like this only covers the IPM through 2014 models? I recently purchased a 2015 for the wife’s daily. Does the 2015 have an “improved IPM” and is not covered by the warranty enhancement program. If the 2015 IPM is “improved” from the pevious years what was done to it to make it better in 2015 and not subject to the problems associated with earlier years? I checked the VIN in the Toyota owners website before I bought the car and it showed nothing for this car in reference to the Z03 warranty enhancement and of course the stealership is clueless. Sure would like to have a 15 year warranty on the IPM since it’s big $$$ to replace and I plan on driving this car into the ground.
