Toyota — Injector issue in innova crysta

Good morning sir/madam:
Myself Rajaram bought new vehicle innova crysta in trichy Aanamalais toyota .six days back there was injector power down problem in innova crysta NO: TN 55 BJ 2425 .so it was sent for service in trichy aanamalais toyota . Regarding this issue there is no clear response and updates from people in showroom even after 6days .since this problem was not faced by us in anyother innova cars .we need a solution and reason for this problem and an assurance that it won’t happen in future.
Thank you.
