NHTSA Complaint #11546513 — 2018 KIA OPTIMA

vehicle stated was consuming a large amount of oil by burning it. this was able to be determined by the lack of oil or residue anywhere on the engine or engine compartment. It was then taken to the dealership were it was determined an engine oil consumption test needed to be done. the test was done and was determined that it needed an upper engine combustion cleaning to correct issue. The vehicle was then scheduled to have this procedure done. upon completion of this procedure the vehicle continued to burn oil as it could be seen out of the tailpipe upon acceleration. a second oil consumption test was performed and was found to be within dealer specs of acceptable oil consumption at 1qt per 1000 miles. When the next oil change was done by an independent garage, it was noted that the vehicle was now leaking oil from what appeared to be the oil drain plug. The dealer was then informed with pictures of the oil leak. The vehicle began leaking more and more oil now at a rate of 1/2 qt a day as of writing this the independent garage inspected again and found that there was a crack in the oil pan just to the side of the oil drain plug. After doing some research it appears to be a very common problem. The vehicle in question is supposed to be taken into dealership to have the issue checked out on the 4th of October 2023. todays date is 9/26/2023.
