AGM battery is sh*t. Need to just go back to flooded or Lithium. So high in price and if they get hot they don't last. Well I live in California desert!!! Average summer day is 110 degrees. GM needs to stop making cars in Mexico and come back to America. This isn't even an American car company anymore. Fu!! GMC

I have had 4 batteries in my 2018 Terrain, including the original. Failed in December 2020, February 2021, and now August 2021. Each time they tell me it is a “faulty battery”. If that is the case, then these glass mat batteries are junk. GM needs to address this problem.
