Consumer Description

I am filing this complaint regarding a catastrophic engine failure in my 2011 Hyundai Sonata. According to Hyundai’s own documentation, Service Campaign 953, issued in 2018, was never performed on this vehicle. This campaign addresses the risk of connecting rod bearing failure caused by residual metal debris in the crankshaft oil passages.
