I know it's been mentioned here before but what is the current firmware/ software for the 2008 hybrid? How do I know if my truck has the most up to date ?

 

the dealer will tell you. make sure it is a hybrid capable dealer.

 

If you have any questions about working with a dealership, John Buttino, please let us know! We're available via private message and ask that you include the last 8 digits of your VIN with your inquiry (helps us check out a few things right away).

Hi,
How to make sure that my Tahoe Hybrid 2008 firmware is up to date.
the Vin number is 1GNFK13558R250740 kindly note that i Live in Jordan.

Thank you

 

My guess is there is no way for a customer to know. There are a number of modules in the vehicle and each one can have it's own firmware. I think only the dealer can tell you if it is up to date when they plug the vehicle into their systems.

 

Thank you
