Brought my car in for routine oil change. Informed dealership of loud exhaust sound. Asked if they could check fo an exhaust leak. Upon picking up my vehicle I was informed the loud exhaust was due to a crack in the catalytic converter. I asked what would cause this to happen. They were unsure of cause it is not a normal issue for the mileage and age of vehicle. They did provide me with a quote to repair. I took my car to a different repair shop and they were concerned that this part was faulty from the manufacturer. They informed me that a recall could be possible and advised me to contact gm.
Starting in March 2019 the 2017 chevy Impala engine would stop and wouldn't start back up for at least 30 minutes. It would happen when I stop at a stop sign or light or whenever I stop the vehicle. Then in July of 2019 the vehicle stopped in the middle of the street. It wouldn't reverse or go forward. It was identified as a transmission leak. All the transmission oil had leaked out. Took the vehicle to several repair shops which they couldn't identify the problem. My transmission is damaged by now. A 2017 chevy Impala should not have transmission problems unless there is some type of defect.
