While I was driving my car, my engine completely died. No check engine light had come on at all prior to the engine dying. There was a clicking sound the motor had been making for about a month but car was running completely fine and normal all the way up until the engine dying. Upon googling 2013 Hyundai Elantra engine issues, I found that many 2013 Hyundai Elantra owners had experienced the exact same problem that I had. I even found out that this model had been recalled in canada for this exact same problem but for some reason, there was never a recall in the us. There was also a lawsuit in the us in 2021 addressing these issues with this faulty engine. This is a clear safety hazard as my car could have died on a highway or at a busy intersection (which I was very close to). A mechanic diagnosed the issue with a worn out timing chain (which is exactly what I had found online in the complaints made by other owners). Here are the notes from the mechanic: verified concern. Found timing chain very worn out and has large amount of slop in chai. Also found alot of lifters not filling with oil and caused damage to cams. Tech recommends timing chain kit cam phazers also both cams all lifters and rockers. Also valve cover due to pcv valve system failure. My car was sent to the dealership by recommendation of the mechanics to see if they would replace the engine since this is a well known issue but Hyundai refused to replace the engine.
