Reading your journey makes me want to cry because I feel like this is what I'm in for. I'm regretting my decision of purchasing my T&C. It's crazy that they don't issue a recall and fix it.

Hi - my final observation and efforts in the matter. Believing the motor warm up throttle up/down behavior is intentional and directed by the system for whatever reason - I went ahead and replaced the Throttle Body in hopes that the new electronic butterfly would cure the lost calibration. Although car ran better, it did not fix the issue.

About 4 weeks ago the drivers side window regulator broke, and required replacement. Because if this, and unknown future risk due to further electronic failure, I traded in the car.

Here is my final summary: the car was PERFECT until the fuel pump relay went Bad and vehicle entered “crank no start condition.”

1. Mistake by me was to take to a trusted local repair man - I should have taken it to the dealership.

Here is is what I believed happened as I was in close touch with the shop during all initial efforts to resolve. The original mechanic repinned variius cinnectors, and the shop brought in an “expert” to overwrite the cars softwares. After no avail, I still had to take the car to the dealership to have the connectors repinned to work with the new TIPM.

After this all other noted bizarre behavior emanated. Then, the brake tail lights stayed “on”, and this requires a third TIPM to be installed by dealership, but they never fixed throttle issues at warm up.

Lesson: these cars need to go to the dealership when issues arise, unless you are very certain how to fix it. If any doubt at all - dealership it.

The reason is that you need all the leverage you can get when investing in the repair, and cost of these parts can over power your local shop persons best intentions. At least the dealership has more test equipment and purchasing power to correct.
