NHTSA Complaint #10538063 — 2012 DODGE RAM 1500

THE TRANSMISSION UPON START UP WAS LOCKED IN 4TH GEAR. THIS IS THE THIRD EVENT OF THIS TYPE. THE FIRST TIME THIS OCCURRED THE TRANSMISSION RESET AFTER I PUT THE TRUCK IN PARK AND RESTARTED IT. A TRIP TO THE DEALERSHIP UNCOVERED NOTHING. THE SECOND TIME WAS ANOTHER COLD START EVENT WITH THE TRANSMISSION LOCKEDN 4TH GEAR. IT TOOK SEVERAL RESTARTS TO RESET BUT THE CHECK ENGINE LIGHT WAS ACTIVATED. ANOTHER TRIP TO THE DEALERSHIP AND THE CAUSE WAS STATED TO BE THE SOLENOID PACK IN THE TRANSMISSION. THIS WAS REPAIRED AND ALL SEEMED FINE. YESTERDAY ANOTHER COLD START AND THE TRANSMISSION LOCKED IN 4TH. I DROVE THE VEHICLE TO THE DEALERSHIP IN 4TH GEAR. ON THE WAY I MONITORED THE TRANS TEMP. IT STAYED AT 86 DEGREES. THE OUTSIDE TEMP WAS 91 DEGREES. UPON ARRIVAL AT THE DEALERSHIP A MECHANIC WENT WITH ME ON A TEST DRIVE. WE RETURNED TO THE SHOP AND HE BEGAN A DIAGNOSTIC. THE CHECK ENGINE LIGHT WAS NOT ON. I WAS TOLD THAT THEY BELIEVED THERE WAS A WIRING HARNESS ISSUE AND THEY WOULD ORDER ONE AND REPLACE IT. THE MECHANIC TOLD ME THAT HE DID SOMETHING AND THE TRANS TEMP JUMPED FROM 86 DEGREES TO 160+. THERE WERE SEVERAL FAULT CODES FOUND DURING THE DIAGNOSTIC. THE TRUCK IS CURRENTLY AT THE DEALERSHIP BEING REPAIRED. THE TUCK HAS LESS THAN 7,000 MILES ON IT. IT HAS THE 4.7 ENGINE. THE FIRST EVENT WAS IN JUNE 2013, THEN TWICE IN AUGUST 2013.
