I have a couple of questions about the unlimited powertrain warranty 5 year inspection. First, for those of us who have aftermarket bolt on's (CAI, headers, etc.), these parts "should" not affect the inspection pass/fail assessment right? Does anyone know what exactly is being inspected outside of obvious neglect and abuse? Lastly, I saw that the inspection has to be done 60 days before or after the in-service date, so is the in-service date the same as the date of purchase? Here is some warranty info I found online:

When the car is sold, your information is entered into the Chrysler database. The "In Service" will typically reflect the date of sale. Build date is something totally different and is not relative to the warranty.

A good dealer will typically not bonk you on your powertrain inspection unless there is just something so totally out in left field that it defies logic. Such as...you made a "Bigfoot" out of your truck.

If you have active DTCs in the powertrain system (engine or trans codes) they will usually have to be addressed before you get passed. Things like misfire codes, catalytic converter, coolant temp, EGR, that can cause engine damage when ignored, are the types of things you will (and should) stay on top of and may cause you to not get passed until you fix.

 

OK good to know. I read a comment on another forum stating that dealers are required to look for any modifications that could impact the powertrain. I can see how swapping internal drivetrain components (cam, torque converter, gears) might be frowned upon or showing up with a supercharger. But IMO external bolt on's that do not touch oil should not be an issue.
