Two problems related to engine and engine cooling have been reported for the 2012 Chevrolet Silverado 2500. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2012 Chevrolet Silverado 2500 based on all problems reported for the 2012 Silverado 2500.
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.
Vehicle would not start when warmed up after shutting off.
