hi all, is it now the trend of battery will suddenly die (cannot start) within warranty period then when seller take back and recharge they will say the battery is good and install back for you.

twice for astra brand diff car, and heard once from bosch also.

yes, borrow you a spare one, rm30 charge if found out the battery is ok after recharge. no charge if go to their shop. but how can i go to their shop when the car already cannot start. really zzzz

thanks for your interest in this. above is what i can gather up for viva.
paid rm30 and loss of time and exposed in unnecessary dangers with an battery under warranty period.

as for another car brv the engine actually still can start but dashboard is blinking all kinds of lights ( even after twice off engine and start back ) but immediately ok after change to spare battery.

even happen once during using the spare battery but after few time off on engine those lights keep disappearing until ok.

after go obd check and clear all those alarms and decided to remove the additional installed obd device for auto lock door since 2017 and ok until today.

paid rm30 and still need using back the same old battery that fail once within warranty period.



as for bosch actually happen at x50 same dashboard lights craziness then change spare battery provided by workshop. workshop charge and said ok then install back.

for viva case would like to know why suddenly the cca dropped and health 75% since the alternator is ok. TIA
