Ignition Coils Failure problems of the 2012 Kia Motor Soul

After work on 4/30/19, I was speaking with the parking deck attendant. The car was in drive, but I had my foot on the brake. It started shaking and sounding rough, as if it were struggling to stay on. I drove it for a few miles, but was afraid to drive more than 35 or so mph. It was shaking and making noise the entire way. I only drove on the interstate to the next exit, so that I could find an open parking lot just in case it cut off on me. I called aaa and got a tow home due to the lateness of the hour. The next morning, aaa towed me to a aaa car care facility and I let them do repairs. I was told that ignition coil # 4 was bad and had to be replaced, and that it would be better to replace all 4 coils. I only had enough money to replace the bad one, plus the spark plugs and air & cabin filters that the mechanic recommended. He said that the other 3 coils should be replaced as soon as possible.
