purchased a 2012 GMC for $12k on a Saturday, the check engine light comes on very next day codes P219A & P219B. personal opinion is codes were cleared before purchase, however we have no way to prove this. this was a problem for us due to we are from NY and in order to pass the emissions inspection the check engine light can not be on. Dealership un-willing to correct the problem at all. Jim Cipolla was our salesman, and he states "I spoke with Brian Vaughan, our general sales manager and he said he would not pay to cover an item that isnt apart of the powertrain. I'm sorry"-who sells a vehicle and doesnt handle issues that come up the very next day after the sale!? Total BS. Do not recommend this dealer.
