FYI, my car has been doing this for more than 1 month. This past weekend, my wife turned on the car and got an "Engine malfunction, Increased Emissions" alert and the car was shaking very badly. We took it in and they said they had to submit a PUMA case.
"As per puma address mis fire fault with line 2 first"
"Misfire fault with cylinder 2. Swapped out coil pack two with one. and Spark plug two with three" They did a test drive and found another misfire on cylinder one. Replaced defective coil pack in cylinder one.
so cost was $450. ???? It drive fine now but it's only been the 1st day. We'll see if it has fixed the problem.
