If send to ordinary workshop to repair the accident damage, yes warranty can be voided depending on the SC whether they wanna lend you a helping hand.

Tensioner bearing is indeed weak on all kampro, and it's indeed not covered under warranty. I would guess that bearing KO prematurely partly caused by the accident also. Feel sorry to hear that, but I'm sure it has nothing to do with SV.

p/s: Yours is SV rite? SV doesn't have fog lamp, if ayam the officer saw the foglamp, I also will accuse you void warranty due to customize fitted the foglamp, as a result tensioner bearing KO

Errr... tensioner bearing is consumable parts, indeed not covered under warranty. Other than that, accident does not cover under warranty as well. So, unless its mechanical failure on the tensioner bearing PRE-accident, then yes it's covered under warranty. I guessed the small SC is really being lenient on claims, hence they allowed you to claim under warranty, or may be that small SC were not informed that your car was involved in an accident previously. Anyways, you should feel gracious on that small SC.
