My engine started making a knocking noise that eventually cut the engine off while in motion. As told the recall was about but Hyundai claim since my car salvaged, they won't pay for another engine when my is the recall problem. Now when everytime I cut the car on it makes a knocking sound then eventually cut off.

With a odometer reading of just under 135000 miles a warning light came on with a message that the hybrid battery was not being charged and then the engine developed a serious knocking sound. We pulled over to the shoulder of the highway. After having the car towed to the Hyundai dealership we found out that metal shavings in the oil meant that we needed to replace the engine.

I just had an oil change no more than 1500 miles ago and I have no oil in my engine. It just disappears. And it constantly makes a knocking noise that Hyundai is unable to fix. Also I had my brakes changed and when I come to a sudden stop, the brakes lock up and make a loud thud noise.

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.
