Within last oil change the engine had oil consumption and has a loud engine knocking sound. The upcoming oil change date had not been exceeded and/or miles had not been exceeded. The engine knock caused me to pull over immediately at a location on a highly traveled road and no shoulder or safe spot which was dangerous. Safety was a concern because I had to wait for a tow truck in cold winter weather. The local Hyundai dealership maintenance person said it was a known issue with that make and model and the repair wait time is 5 months because they don’t have enough staff and cannot get parts. My tuscan just had an inspection at the last oil change on 10/22/2024. no report from Hyundai that the oil level was an issue or engine having problems. There not any warning lights or low level lights and/or noises until it suddenly happened.
