NHTSA Complaint #11592313 — 2017 LEXUS IS

It was regular morning on memorial day and I had not used the car all weekend since I really dont drive unless it to and back from work. I started the engine like would any other day and the car began to shake out of nowhere. The check engine went off, the yield sign went off and the traction control went off. I thought maybe it was time to change my brakes because the dealership had recommended it. I changed my brakes and got new tires but the car still shook. I continued to drive like that to work because I had no choice it shaked mostly on idle and I drove like that for a few days on Friday as I was coming back from work on the freeway the car shook in the freeway as I exit out the freeway the car felt almost if I couldn't pick up an speed and I got extremely scared with the cars flying by. I decided not to drive and take it to a nearby mechanic I thought maybe the spark plugs or coils might be the issue but after 3 days in the shop and replacing spark plugs he confirmed it was the direct fuel pump and possibly the fuel injector....my car is only used to drive to and back from work and only has 58k miles. I believe this is a default manufacturer part and I need help recalling this particular part on my vehicle.
