It could be that the battery is not getting charged when the car is running. Could be an alternator issue as patchyboy suggested. The TASS never agree when we mention or explain an issue. They try their own ways to resolve an issue. When My Punto's battery almost died, the technicians were still trying everything possible with the FIAT Examiner. They could not confirm that the battery is dying. The roadside battery shop guy didnt take even 5 mins to confirm that battery is almost dead. Once I replaced battery, the starting problem, hot start problem, and all the error messages on the MID vanished for ever. TASS expects the Examiner to declare that the battery is dead or is dying.
