2013 Hyundai Elantra power train problems

“2013 Hyundai Sonata has a loud knocking noise from engine. Purchases 8/5/25 at 43K miles, currently at 44K miles. There is a Technical Service Bulletin, # 22-EM-009H dated June 2022 about an extended warranty but its time limit is questionable. Unknown and undocumented when purchased. Not listed as an official recall so not covered under warranty repair and the only course of action I have been given is install a new motor quoted at $15K from local Hyundai dealer. Further research shows that driving should be limited to avoid further engine issues/fires. Occurrence since January 2026. Progressively worsening. Cause for concern. Is there an official recall on for the piston flap pending? Unsure if accident noted below is due to the issue.”

“A significant engine failure occurred while driving, presenting as loud knocking from the engine. The issue developed without prior warning lights or messages. The vehicle was inspected by a dealership and the problem was confirmed as internal engine failure (piston slap/engine knock). The dealership recommended full engine replacement. The engine is available for inspection upon request. There was no evidence of sludge or lack of maintenance noted during inspection. The most recent oil change had been performed less than 1,000 miles prior to the failure, indicating the issue was not caused by lack of maintenance. This condition creates a safety concern due to the potential for sudden engine failure, loss of power, or engine seizure while driving, which could increase the risk of an accident, especially at highway speeds. The issue has been confirmed by a dealership and has not been repaired due to cost.”

“My engine is ticking. The auto shop told me that my motor is shot and the same thing happened to my sons car. We both have the same car same year. There has been a law suit for this issue.”

“I was driving under 10 miles an hr because the roads were still wet from the night before as i am on the ramp to get on the highway barely turning the wheel it locks all the lights come on the dashboard such as abs and i crash into a railing because i couldn't move anything. Again only last week after this has been supposedly resolved driving barely going 2 miles my bf was actually driving and again roads were wet same thing all the abs sensor lights come on the dash the wheel locks and the car doesn't move, it's scary and ridiculous the amount of others I have found experiencing the same issue and from that accident I can barely drive now my anxiety and ptsd from the event has even affected my work so now I am losing money I didn't think I would ever fear being in a car and I hope you guys fix this so no one experiences what I am currently experiencing.”

“The car failed to go into the park. The vehicle was in park and continued to roll, and we placed the emergency brake on. The vehicle was towed to the dealership. The dealership replaced it with a new shift cable clip, and now the car operates. We noticed the vehicle had a previous recall that was repaired in 2019. The shift clip repair is for the same clip that failed, resulting in being unable to shift in gear. When asked why we were charged for a recall repair that didn't last, we were told we could only fix a repair once and that we needed to pay. The concern is if this vehicle was Parked on an incline I could roll forward running into something and someone. From the record there was roughly 40k miles between recall repair and the failure of the clip that was supposed to fix this problem.”

“The contact owns a 2013 Hyundai Elantra. The contact stated while driving at various speeds, the vehicle hesitated upon the depression of the accelerator pedal. The contact also stated that the vehicle would shut off while idling with the check engine warning light illuminated. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 200,000.”
