Sorry, I can't agree. I cannot find any reputable references to support your position. Show me data. And use the 2011 thru 2016 model years as a comparison (the 1.8l engine)
Unbiased major car sites consider the Elantra as a very reliable vehicle, on par with the Civic in reliability.
Really......My dealers had 8 bad motors in when mine was done. I called another dealer and they had a bunch too, but would not say how many. The sb11 guy here (I think) said their sister dealership of another brand is doing Hyundai motors because they have too many to get done.
I have a relative who is a mechanic at a large Lexus dealership in Minneapolis and they get ONE new motor warranty every 3 months or more. And a Honda Fit motor is so reliable of a motor it is approved to be used in aircraft by the FAA.
I don't need to even lift a finger to find more evidence to bolster my opinion. You don't have to like my opinion, but from my research on all my other forums Honda and Toyota I see 1to 3 bad motor posts a year. You come here ......well enough said, dropping like flys. You keep reading your J.D. Powers website info if it makes you feel better.
