2011 Hyundai Elantra: engine knocking or ticking

Filed Feb 10, 2026 · Engine · OH

I have a Piston/Engine Defect according to the mechanic at the car shop. Any time any acceleration is applied you can hear the knocking. I believe it should be covered through the class action alleged that 2011-2016 Elantras engines (including the Limited trim) have a piston defect leading to engine failure. A settlement offered extended warranties, engine repairs, and reimbursement. I was unaware and have already spent tons of money towards repairs to the engine over the years. Now I am aware of this lawsuit and would like some kind replacement.

When I start the engine, I hear pronounced knocking sounds in the engine for approximately 1-2 seconds, and they are quite loud. As the engine warms up, the knocking persists, albeit at a lower volume. The ongoing knocks are not as loud, resembling a consistent noise similar to that of a diesel engine, although it is not a diesel-powered vehicle

Had oil changed at Take 5 recently as always do. 2 weeks later car cut off 3 times in traffic. Engine light came on. Car started to lose power/acceleration and engine began to make a ticking/knocking sound. I checked the oil and none was in it. I added 4 quarts to see would that help. It did not.

My daily driver began to make a knocking noise and my dashboard break light indicator came on. I immediately scheduled service with my hyundai dealer. But it did not make the (2) days wait. While driving at highway speed the front end began to intermittently pull to the right as if the right front brake was being tapped independently. Within minutes all of the electrical shut off and the engine stalled. I drifted to the side of the road. After several attempts the electrical did come back on but the engine would not turn over. I had the vehicle towed to closest hyundai dealer, who said the engine needed to be replaced and all that was available was a used engine with 60,000 miles on it at an approximate cost of 5,000.00 dollars with no guarantee that it may require additional repairs.

The vehicle experience rod knock with 57,000 and vehicle has erratic transmission shifting. The dealer explained they would cover 60 percent but my cost is still 4,000.00 for which the vehicle is only worth 6,000 on trade. Plus $600 to fix transmission problem. Requested picture from dealer but only sent pictures of metal shavings in oil pan and valve cover.

My 2011 hyundai elantra has this ticking sound coming from the engine for over 12months. I has constantly called even had the car towed 4 to 5 times to the same dealership for the same thing that the hyundai motor want and wouldn't declared the car a lemon. The car constantly would not start or when it did start while driving it would slow down and then shut completely off where I would have to restart the vehicle back up. The car is always keeped in a close garage and regardless to the weather it continue to make this loud razzing noise in the engine. Service manager chad repeatedly told me that there was nothing wrong and that it was because of the weather. Now the dealership wants me to pay 7000 dollars for a new engine
