2013 Hyundai Sonata Complaints

  • Engine 06/13/2026

    Engine developed a loud rod-bearing knock at approx. 107,771 miles, consistent with the Theta II GDI connecting-rod bearing defect addressed by NHTSA Recall 17V-226 (Hyundai Recall 162). The vehicle was taken out of service and delivered to Webb Hyundai, Highland, IN, on 06/13/2026, where it remains. Hyundai's own campaign records confirm Recall 162 (GDI engine inspection/replacement) was completed on this VIN on 10/02/2017 and the KSDS engine-monitoring software (Service Campaign 953) was installed 08/09/2019 - yet the engine has now failed in exactly the manner the recall was meant to remedy, indicating the recall remedy was ineffective for this vehicle.

Although the dealership identified connecting rod bearing failure, Hyundai Motor America declined to replace...

    I am writing about my 2013 Hyundai Sonata VIN: [XXX]. On [XXX] my vehicle experienced a knocking noise from the engine and the Illumination of the check engine light. The car lost power and I was unable to drive it home. I had to call a tow service to have the car towed to Alan Turner Hyundai, 6501 Pensacola Blvd, Pensacola, FL 32505. I spoke to a service writer at Alan Turner Hyundai. He told us that they could not help us and to contact Hyundai corporate office for help. We purchased this car brand new from Alan Turner Hyundai. We visited your web site and put in our VIN and the system stated that our vehicle was affected by the Sonata and Santa Fe Sport Engine Recall Campaign. We are an [XXX] with one car, and that car has stopped working. We need help in getting this car repaired under warranty via the Sonata and Santa Fe Sport Engine Recall Campaign. Thank you.
