Had my engine light flashing yesterday on highway at 70 mph. Had code read today and it came up P0300, a misfire.
I'm filing a complaint about my model year 2010 GMC Acadia. My check engine light has come on at 96,000. The code is P0008. This code points to the timing chain. This is a known issue with GMC Acadia's and is the same issue that caused GMC to extend their powertrain warranty on 2009 model Acadia's to 120,000 mile or 10 years.
