2010 Cadillac Escalade motor needs to be replaced, according to the Cadillac dealer. It only has 140K miles, I am the original owner. Has anyone ever had this happen? Really upset as I paid alot for the Escalade bought it new & thought it would last till 200K miles. Cadillac will not help with cost of motor & dealer (Sewell) will only help with 1500.00 of the 14K cost…Now I need a new automobile. Thoughts…
