Hi and thanks for using 2CarPros. Com. There was a technical service bulletin sent to dealers indicating various problems with the remote start not working. I have attached it for your review. If the problem is related to this issue, the computer may need re-flashed which can only be done by a dealer.
Take a look at the attached.

Intermittently the vehicle may not perform a Remote Start when the FOB is pressed twice, The head lights will flash once. The vehicle runs only when the "Start" Push Button is pressed or when the FOB is used in the WIN.
NOTE :Two TIPM calibrations may be displayed, one for 2009 Model Year and one for 2010 Model Year. Please ensure you pick the correct CORRESPONDING Model Year flash for the vehicle. Review the flash description to be certain you are selecting the proper file.
If the customer states that the remote start is inoperative. First check for codes if Diagnostic Trouble Codes (DTCs) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If the Remote Start Inhibit DTC "Power Loss" is present in the TIPM then the TIPM must be flash reprogrammed with new software.
NOTE : If this flash process is interrupted/aborted, the flash should be restarted.
1. Using the wiTECH Diagnostic Application for flashing a TIPM is made available through the wiTECH Diagnostic Application. For instructions select the "HELP" tab on upper portion of the wiTECH window, then "HELP CONTENTS. This will open the Welcome to wiTECH Help screen were help topics can now selected.
2. Clear any DTC's that may have been set in other modules due to reprogramming. The wiTECH application will automatically present all DTCs after the flash and allow the tech to clear them.
I hope this helps. Let me know if you have other questions.
