The wiring harness is now on back order, leaving me without a car for weeks or longer. The vehicle has plenty of oil, and the dealership confirmed there are no engine problems, yet the warning light keeps coming back because of the faulty harness. This happened 1 day after buying this car new from the dealership lot.
