Intermittent "F" & "AIB Fault" on 2024 Tata Altroz Manual - Randomly refuses to crank

Hey everyone,

​I am facing a highly frustrating, intermittent starting issue on my 2024 Tata Altroz XZ Manual (Petrol), clocked at 3,980 km.

​

​

​The Issue (Multiple attempt to crank up engine):

​

​Attempt 1: Turn ignition on -> Dashboard immediately throws a prominent "F" symbol, cycles through "AIB Fault", and refuses to crank the starter motor at all. (Note: The infotainment screen stays completely ON and normal during this).

​

​Attempt 2: Turn it off and try again -> The "F" disappears, and the engine cranks and starts perfectly, idling smoothly around 900 RPM.

​

​Attempt 3: Turn it off and try again -> The "F" and "AIB Fault" are right back, locking me out again.

​

Has anyone faced this exact intermittent "F" fault loop on an Altroz? What did the service center end up replacing to fix it?
