Problem overview

Some Lincoln MKX owners report experiencing issues with exhaust fumes entering the cabin, posing potential health risks to occupants. This concern has been particularly noted in the 2016 model, which has an average failure mileage of 44,500 miles. While exhaust system problems account for about 1% of all complaints from Lincoln owners, the majority of these reports come from MKX owners, with a total of 7 documented issues related to the engine exhaust system.
