2011 Hyundai Elantra: engine failure

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.

There was total engine failure when the car reached about 80k miles. This is known for in the 2011 hyundai elantras but hyundia has yet to recall the elantras just the sonatas. Despite constant and frequent oil changes oil sludge formed and entered the engine compartment completely rendering it unrepairable. A "new" engine had to be placed but I was warned the problem could occur again but a recall still has not been issued. This is dangerous as the engine was sputting out, misfiring and blue smoke was being released from the exhaust due to this

I was told that metal shavings were found in the engine block and they also covered my camshaft position sensor. The metal shavings lead to the pistons not getting enough oil and it threw a rod, as a result of these medal shavings and little oil viscosity. The car was in motion, on the highway.

Car will lose power while driving, on occasion it can be jumped / restarted, but it will suddenly lose power again. Have towed it 6 times in 5 months. Now I'm looking for an entirely new engine. Side note: you can't put the car in neutral to tow it if there is no power, so you have to hope jumper cables will get it enough power to put the car in neutral. No manual steering either, so we had to use a tow truck several times since you couldn't turn corners manually at all the steering wheel just locks, even with the key in the ignition.

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

I noticed a ticking noise coming from my vehicle. I took it to a hyundai dealership and they informed me I would need to replace my engine. The vehicle has 73,000 miles and was maintained (oil always changed on time). I bought the vehicle from my grandfather and had it less than a year. Because I was the second owner, I was not covered under the 10 year/1000,000 mile warranty. The hyundai dealership submitted documentation and photographs of the engine to see if hyundai would cover any of the cost of a new engine. Hyundai declined to cover any of the cost of the engine. I called customer service and was assigned a caseworker to look at the submittal in greater detail. The caseworker informed me they would not cover any of the cost regardless that many people were having the same problems with their engines.

The crankshaft pulley stripped from crankshaft! About 30k miles before we started noticing engine noises - loud ticking noises. After having my spouse park the vechicle because was hard knocks, I took it out with my daughter to take her to guitar lessons and to listen to it as I drove. On the way back to the (less than 3 miles) the engine died as there was a loud screech/knock. I restarted the enigne and drove back home. The coolant and oil was everywhere. That's when I notices the pulley was loose and I was able to pull it off the crankshaft. The oddest thing I've ever seen. The engine (I believe) still starts but ticketing does persist. Not sure what happened but clearly the engine had some issues with it. There was nothing we've done with the vehicle other than normal, highway driving. I've contact corporate hyundai and they have indicated it's not longer covered and no work can be done on it. My concern - outside of 5k lost on the vehicle is this is a major concern for all the vehicles out there - especially at the lower mileage. I freaked out on the road when I heard the noises and felt like my engine completely fell apart. My safety was my concern. Something is wrong with this engine and it's not just mine. If it happened to me...a similar occurrence is happening to others. I sense hyundai is not doing it's part to rectify this issue especially with such a core/critical part of the vehicle. I've lost confidence in their vehicles...especially with lack of ownership of the issues. (vehicle is still at dealership at the time of the writing). I'll be picking it up today. I"m estimating the date this happened...because I didn't mark it down. I tried to tow it myself to the dealership with my truck but I took the bumper off so finally got a real tow in to picker it up and relieved it.
