Team,

I own a bullent 500 standard kl-52k-3684- (Make 2016), regular service the vehile at authorized showroom where i purchased the vehicle which is concept bikes - kazhakuttom - trivandrum-kerala.
The last paid service i made was on feb 28th 2019.
Recently i hear a tap sound coming out of the engine and when i took the vehicle to th showroom, was informed that the crank has gone faulty and needs to be replaced.

I asked why this occurred as the vehicle do undergo periodic regular service, the bike has only run 17250 kms and is single owned. I have not received any reply instead they asked to replace it where it costs 15000 for new one.

I need this to be covered under my bike warranty for the following reasons.

Newly purchased vehicle and do undergo periodic service - why this was not checked initially by the technician team as the periodic paid service do accrue bills wherein parts are replaced, but it ended up vehicle having major engine failure which was ignore by the technician at workshop and led to this major problem.
Vehicle has only run 17250 kms.
