Aiks! How old are your cars? Why the SA never inform?
When I deliver cars, I repeat so many times like a broken record because I also experienced this warranty problem with my old Myvi. 6 years warranty gone because the service advisor told me "come next month also nvm one".
Hyundai got kasi chance. Not more than 500km or 15 days late. I repeat this many many times also. Sometimes I panic and start chasing my customers to come for 1k service, not knowing they already did it somewhere else. Haha.
Must follow schedule if got extended warranty, I.e. any car maker that offers 4 or 5 years warranty today. Please be wary if they say late also "nvm one".
Please remember to service
1. First 1000km done or within 1st month.
2. At 5000km done or in 3rd month.
3. At 10000km done or in 6th month.
Subsequently,
4. Semi syn - every 5000km or 3 months, whichever comes first.
5. Fully syn - every 10000km or 6 months, whichever comes first.
My SA told me follow the mileage and my first mileage done after 3 months and service advisor also didn't not told me on the service interval.
However, i need to admited it is my fault for not read the manual carefully.
