NHTSA Complaint #11560800 — 2017 HYUNDAI SONATA

On February 27, 2023 we went to the Hyundai Dealer because our engine was leaking oil and we were told by Pep Boys that the Rear Main Seal was leaking. The Dealership scheduled us a service appointment three wks later, on March 23, 2023, when they replaced the valve cover gasket and the high pressure fuel pump gasket. On Jul 15, 2023, 2.5 months later, we return to dealership because our engine was leaking oil again and had leaked into the spark plugs tubes. They replaced the valve cover gasket again. Two weeks later on July 28, 2023, we went to the Dealership because the engine light turned on and the engine was misfiring while driving. They did nothing but added 3 quarts of oil because our oil was low despite us changing our oil 1 month prior (June 28, 2023). On September 25th, we returned to the dealership because our engine light turned on and our engine was violently shaking while making noise. At this point, we were frustrated and did not feel safe driving the car. We pleaded with the Service Manager to replace the engine from all the issues we have been experiencing including having to constantly add oil or change oil every 2.5 months. They held on to our car for 1 wk and gave us a rental. After inspecting our vehicle they replied that there was no engine issue detected so the Manufacturer will not replace the engine under the warranty. They only replaced the spark plugs and charged us with the service, parts & rental costs. It is now Monday, Dec 18, 2023, 1 wk before Christmas, and our engine light turned on once again while driving with our toddler in the vehicle. The engine not only misfired but did not allow us to accelerate beyond 30mph during high traffic hours on a road with a 50mph limit. The next service appointment available is 10 dys away, Dec 28, 2023, and they are asking us ~$400 to service the car. We feel helpless with the dealership/manufacturer, they are refusing to replace the engine. We fear that they are waiting for the warranty to expire.
