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.

My mother's vehicle caught fire while in park and it’s listed under a fire-risk recall. Another car got damage with the fire. I want to open a claim.

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 vehicle has a piston slap ticking issue and Hyundai will not help me fix this because it’s a common issue by Hyundai.

While driving on an interstate on March 12, 2026, the engine stopped working requiring that the car be pulled over to the side of the road. There were no indications of issues as oil had been regularly changed, and the battery and tires were replaced in fall of 2025. The check engine and oil lights all flashed at the time of the incident, not before. Fortunately, we were able to pull over to the side of the highway, and a tow truck brought the car to a service center. The initial diagnosis was that the seal on the crankcase failed. The service center, and now the Hyundai dealer, do not know the cause of this catastrophic damage that may result in the need for a full engine replacement.
