I am considering getting either used Hyundai Elantra 2012 (RM32k+-) or Kia Cerato 2014 (RM40k+-) .

Can sifu here give me more insight about the model above
1) Fuel consumption
2) Regular maintenance prices
3) Common big/small issue or failure
4) should I consider sonata as 2012 model cost about 35k only or accord 2011 about 40k

According to my decent knowledge friend , the Elantra is quite problematic , but the internet says otherwise , so if there's any reason I should not consider the Hyundai or Kia let me know mainly annoying issues here and there (reliability) .
