Takata recall - car is blowing out smoke - in 700 miles it has lost 2 quarts of oil, it has under 50k miles, it is covered under 2 different recalls thru Hyundai but they refuse to replace the engine, when you try to accelerate - the car will hesitate and then all of sudden blow smoke out the back - so much that you think the car is going to catch on fire, we have had it in the dealership 3 times already - contacted them other times in between. Now when trying to accelerate at just 1 rpm smoke comes out the back car starts shaking like its going to stall out check enginge light comes on - a few seconds later big cloud of smoke comes out back and car will then move leaving trails of smoke behind. Check engine light went off. Hyundai said unless the check engine light is on - it wont matter. They just want us to do a oil consumption test - the engine is making a knocking noise. Hyundai has heard it too. We leave so much smoke that we cant see a car behind us. It can barely make it to accelerate on the highway. 6/21/17 - massey Hyundai hagerstown 7/18/17 - massey Hyundai hagerstown 8/28/17 - massey Hyundai hagerstown Hyundai case #10553414 - they know about it! we have had it towed to the shop 2 times now.
