“While driving the automatic transmission shutters when going into second gear and stalls before accelerating. Some times the car won't start and it's not related to the battery or the starter. It also had a purge valve replacement three months after purchase. A few months later I had to replace it again this time it wasn't under warranty. I purchased this car brand new in 2018 and it had all these issues in 2018 and october of 2019 is when the transmission began to shutter.”
