Manifold/header/muffler/tail Pipe problems of the 2007 Jeep Commander

Mid September after dropping kids off at school the Jeep died twice right in a row. The Jeep also started this weird hard down shifting in certain gears. A few days later the Jeep died again after I got on the highway, while I was driving 70 mph. Since then the shifting is getting worse. A check engine light comes on when it dies, the codes were read by an auto parts store. There were multiple codes, electronic position sensor, intake, and manifold. I tried to file a complaint with Chrysler but they will not complete it until I pay their authorized dealerships to read the codes. After resetting computer it has not come back on. The Jeep still shifts erratically, and I discover that the etc warning light does not work. Why???. I don't know we have had this car for 5 years and I have never seen the light. Something is definitely wrong. Please help. Also neither my husband or myself are tall enough for our knee to even think about bumping the ignition switch.

The engine warning light was been on and off for the last 2 years. We have changed-out O2 sensors and other fixes but the problem persisted. The issue was discovered by the local Jeep dealership: four of the bolts attaching the manifold onto the hemi 5. 7l engine of our Commander were broken. The bolts and exhaust manifold gasket are being replaced - $642 cost.

The contact owns a 2007 Jeep Commander. The contact stated that while driving at various speeds, the vehicle stalled several times without warning. The vehicle was able to restart after a few minutes. The vehicle was taken to the dealer to have a diagnostic performed. The technician was able to duplicate the failure and stated that the manifold air pressure needed to be reset in order to repair the failure. The contact believes the failure was not corrected. The failure mileage was 50,448 and current mileage was 50,872.
