Vehicle purchased from dealer 3/5/25 (brand new). Noticed struggle to start/shaking vehicle/weak power, within first week. Malfunction indicator light came on 4/15/25, brought into dealership for testing. Data showed fail/pass misfires upwards of 30 times. Diagnosed as fuel injector pump misfire. Part was replaced and picked up the vehicle 5/8/25. Vehicle misfired again on 5/9/25. Brought into dealership for further testing; service advisor stated that the misfire was "likely due to air in the new pump." Noticeable misfire again on 5/27/25, no malfunction indicator light came on, notified service advisor. 5/30/25 vehicle misfired significantly, malfunction indicator light came on again, brought in for service. 6/11/25 service advisor stated they are doing a "pin fit repair" to refit all the connector pins for the ignition coils. I don't feel safe in this car. It's brand new, and should perform as such. When it misfires, I can barely drive past 30mph. It shakes violently, and I don't know whether it is safe to be driving it. Dealership doesn't seem to understand what the actual problem is.
