I have a 2014 Kia Rio. I have been doing my own oil changes since after the first one by the dealer.
I have not kept the receipts to the oil I have purchased.
If something goes wrong down the road can I be denied warranty service because of holes in my maintenance record?
It all depends on where you live. The major thing is did you keep record of when you did the oil changes and what the mileage was at the time. Also, if the warranty item in question has nothing to do with scheduled maintenance, there is not issue whatsoever. Here in the US, yes they can deny you warranty coverage for your vehicle if you cannot prove the maintenance schedule has been done. They cannot, however, deny you the right to do maintenance on your own vehicle.
Again, this applies to the US only. Other countries have their own laws.
