This Problem Across All Years
The Transmission Control Module failed causing the vehicle to loose power and operate only in "limp mode". General Motors does not have a replacement module available, leaving the vehicle inoperable. GM has no reliable information as to when a module will be available. I had to use a third party service to try and repair the module for a cost of over $1,200. This seems to be a common problem with the 2008-20015 GM Duramax with the Allison transmission.

I HAVE BEEN HAVING MULTIPLE GLOW PLUG FAILURES ON MY VEHICLE. ONE RIGHT AFTER ANOTHER. IT HAS GONE TO THE DEALER EVERY SINGLE TIME FOR THE REPAIRS I EVEN ASKED THE DEALER MECHANIC IF I WAS THE ONLY ONE AND HE STATED THAT THERE ARE MANY OTHERS WITH MY ISSUE WITH FAILING GLOW PLUGS. THE DEALER HAS A FULL RECORD OF ALL THE ISSUES IV HAD AND EVERY TIME MY VEHICLE HAS BEEN IN THEIR SHOP. SOMETHING HAS GOT TO BE DONE! SOON AS I TRY TO USE MY REMOTE START THE TRUCK STARTS THEN DIES THEN I GET A CHECK ENGINE LIGHT SO I CALL ONSTAR THEY GIVE ME THE CODE AND SURE ENOUGH ITS A FAILED GLOW PLUG. THEN IM UNABLE TO EVEN USE REMOTE START FEATURES OF MY VEHICLE AT THIS POINT.

WHEN TEMPERATURES DROP BELOW 30 DEGREES THE TIRE PRESSURE WARNING LIGHT AND THE LOW COOLANT LIGHT COMES ON. TOOK TO DEALERSHIP AND THEY ADVISED THAT BOTH WARNING LIGHTS DO THAT BELOW 28 DEGREES. THIS HAS OCCURRED SINCE 2013 WINTER. GLOW PLUGS GOING OUT ONE AT TIME GM WILL ONLY REPLACE AS THEY GO OUT UP TO 120000 NOT ENOUGH BEING DONE WITH THIS.
