At just 600 miles, the 2023 GMC Sierra 3.0 Duramax gave out a check engine light. The code reader displayed a P0402. The truck had a very strong fume odor. The truck was taken to service two times. GM engineering made tests on the truck and concluded that the truck needs to be reprogrammed. I have a case number established with GM (case number 9-9217617941). If the program is bad, why release the product to the public? See attached invoice for details. This issue is present on almost all LZ0 GMC trucks based on people I've met in forums. Please help us.
