2013 Hyundai Sonata Complaints

This is a well-known and widely reported issue: 2013 Hyundai Sonata Hybrid car, which has recently experienced the following dashboard alert: "Hybrid system warning! Safely stop and do not drive." When the car is pulled over and shut down and sits for roughly 10 minutes, it starts up just fine and runs again for an undetermined amount of time, and then the alert will go off unexpectedly. This has happened twice, once the car was driven about 4 miles, and the alert came on, and the second time the alert came on as the car was started for the first time of the day. The car repair shop indicates that there are no codes saved when this happens. This is apparently a documented issue, where the codes are not saved, and difficult to diagnose by repair shops and dealers. It could lead to the vehicle completely shutting down while driving at highway speeds within traffic, which could cause a serious accident involving multiple vehicles and people. Why is this not recalled by the dealer a...

The contact owns a 2013 Hyundai Sonata. The contact stated that while driving at 65 MPH, the vehicle suddenly locked up. The engine was previously replaced in March at an undisclosed location. The engine light was illuminated. While using the code reader, he received the P0711 code related to the temperature sensor in the transmission. The contact indicated the failure was due to the temperature wiring harness. The vehicle was shifting hard. The contact stated that the failure was related to TSB 19-AT-015H. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was approximately 82,000.

Engine was replaced in 2023. In March 2026 there was a fuel line leak to include fuel misting near heat components. The vehicle was in a fender bender but Hyundai determined this did not cause the leak which eludes to this being a faulty installation of the engine replacement associated with the recall. I’ve reviewed my 2023 engine replacement invoice. I see the Service Kits were used to transfer parts from my old engine, but the High-Pressure Fuel Pipe (35340-2G710) is not listed. Per Hyundai's GDI service protocols and Recall 180, that pipe is a one-time-use safety component that should not be reused during an engine swap due to fire risk. Since it is leaking now, it’s clear the old pipe was reused and has failed. I'm asked for a goodwill replacement because this was a procedural error during the 2023 warranty work and was denied. This is a safety issue.

I am the original owner of a 2013 Hyundai Sonata (under 90K miles). In April 2026 the engine suddenly locked up without warning. The vehicle was towed to Massey Hyundai (Hagerstown, MD) and a claim was submitted to Hyundai Motor America for an engine replacement under Hyundai’s lifetime engine warranty program for affected 2.4L and 2.0L Theta II engines. I provided records I could obtain. Some oil changes were performed at home by my stepfather & several were performed by a local independent garage that has since gone out of business those records are unobtainable. I explained this & submitted all existing documentation. They denied my claim twice and closed both cases. I requested the official written denial, the date it was issued, the specific reasons for the denial, and the name and department of the individual who made the decision. Hyundai refused to provide any of that information, stating they “cannot disclose the information or documentation” and that the denial is “final.” Hy...
