Since my car had about 45000 miles on the odometer, it has been producing a thick white smoke, not only upon starting the car from a cold start, but also after longer distance trips over 30 miles. After having taken it to the dealership multiple times, their response has been that they cannot recreate the problem and most likely it is from engine sludge due to not maintaining the regular oil change schedule. After having shown the dealership the timely maintanence schedule I had performed on the car over the years, they continued to claim that there is no problem with the car. After the standard warranty had run out one year later and upon taking it to the dealership they claim that I need to replace the head gasket and it would cost me $3500. In addition to the avoidance game they played over that year, in my opinion they were simply pushing back the maintenance until the warranty ran out. This is a common problem with this specific car and the low mileage and I know of at least one more family experiencing this problem. There needs to be a thorough investigation on not only the problem with the engine of this car, but the potential of unscrupulous business practices of the dealerships.
