Engine light came on. Took to auto zone & vide 0713 & P0711. I also took my vehicle to aamco which verify the sensor in the vehicle needs to be replaced however they have to take the transmission apart to fix. I only have 31,000 on my vehicle. Has there been a recall already or do you expect this should be covered under 1000,000 even though I am 2nd owner. They did give me a card for roadside assistance

I am the second owner of the 2012 Elantra with 85200 miles. I have had it for 1 1/2 years and now my son owns it (as of Aug 2017, making him the third owner. He lives with me). The oil has been changed as required. The ticking sound the engine made since we got the car has been steadily increasing in sound, and of recent, it is the worst it has been. I sell cars full time (our dealership owns 2 Hyundai stores), and I also own another 2013 Elantra that I drive presently. Our service dept took apart the engine (on the 2012) to find metal shavings which led to the diagnosis that I need a new engine. My son is 2000 miles out of his extended warranty, and Hyundai, nor the warranty company is eager to fix it. I was told by our service dept that in the last month and a half, 5 Elantras came in with the same problem needing new engines and Hyundai wouldn't replace. Hyundai states they are not going to do a recall, even though this is becoming a bigger and bigger universal problem with Elantra owners. The ticking is loudest when running cold, and/or in cold weather. (car is in Ohio). Metal shavings from the engine found in the oil is not a 'normal' issue. I am seeking recourse with Hyundai to fix/replace my engine. The date stated on this form as to "when did this happen" is when I took it to my dealership at work to have it looked at. The ticking has been ongoing since I purchased the vehicle, but never as loud as it has become. My son has had the car at college, but I keep track of it needing oil changes and have documentation.

All oil changes for this car has been done at a dealership since my stepfather bought this car. Upon his death, the car had 111,000 miles when the title was transferred to me. Cold weather was approaching and I wanted to get an oil change done. The dealership could not get me in for a week and even cancelled an appointment I had to I went to exhaust pro. When the temperature got to 20 below zero wind chill the engine started ticking. I took the car to dealership and had them change oil but the ticking persisted. I took the car to dealership to inquire about ticking noise and was informed there are metal shavings in oil and engine needs replaced costing $9400. This is a known problem with the 2012 and 2013 Elantra but no recall has been done like the sonata. I feel that Hyundai should replace the engine at no cost to me. It may not be under warranty anymore but Hyundai knows there is a problem and they should be held accountable and not the consumer.

My steering is loose and the wheel clunks and rattles. Sometimes it feels like the steering wheel will come right off. I can hit the slightest bump and it will rattle and shake like I ran over a huge pot hole. Also, when I'm driving the car will suddenly slow down and whine like I hit the brakes even when I didn't. I was almost rear-ended when I hit the gas but the car decided it wanted to suddenly slow down a few seconds later. There is something terribly wrong here. The engine is also making a ticking/knocking noise when warming up. This happens daily.

When the weather got cold the engine started making a knocking noise. Took it to the mechanic and he said the block would need to be replaced and to contact Hyundai since this seems to be a common problem with the 2012 Elantra. Fyi: The check engine light never has come on for this problem.

Periodically (including today) my Elantra will not start. All electronics turn on and the battery, engine, oil indicators appear on the dash. As many others have mentioned I wait 5-10 minutes and try my car again it will work just fine. Had a few diagnostics where the dealer suspected battery or oil change but I've had several batteries since oem and keep up to date on synthetic oil. Searched online and found many other complaints regarding range shift being the culprit. Either way I'll be taking it to be inspected before it gets any worse/will not start at all.

The contact owns a 2012 Hyundai Elantra. While driving at unknown speeds, the vehicle jerked and the air bag indicator illuminated. Also, the brake lights failed to work. The vehicle was taken to a local dealer (henderson Hyundai, 46 N boulder hwy, henderson, nc 89015) where it was diagnosed that the fuel injector was clogged and the vehicle had an oil leak. The vehicle was not repaired. The manufacturer was not notified. The failure mileage was 60,000.

My 2012 Hyundai Elantra began having acceleration problems for the past 6 to 9 months. As I step on the gas at approximately 30 to 40 mph the automobile kicks, bucks and does not accelerate as intended. My Hyundai dealer replaced the fuel pump/assembly ($700) and it seemed to get worse.failure to accelerate as expected is a danger if you are trying to enter a busy highway or trying to get out of the way of another speeding vehicle. This seems to occur at speeds up to 65 mph when stepping on the gas. This happens on a regular basis but not every day.

"takata recall" poor engine performance. Rough idle at cold start. Smell gas as well. Randomly blows huge amounts of smoke out the tail pipe while accelerating. "example" merging on interstate. This has been going on since the vehicle reached 50,000 miles. All maintenance work has been done. Now at 77,986 runs like a grass cutter. Just runs rough.

When attempting to start my vehicle it would not start. All lights came on, but the engine would not turn over. After turning the car off and sitting for 10 minutes it finally started. Two days later my vehicle did the same exact thing. I took my car to the shop and they found nothing wrong with it. While at the car shop another Elantra owner (2011 model year) was there with the same issue. I am unsure exactly what the problem can be but I did look online and many owners for the Hyundai Elantra model years 2011-2013 complained of the same issue.

  • 84,000 miles
I have an issue with a 2012 Hyundai Elantra. It currently has 84,585 miles and I purchased it used from a dealership at 48,484 miles. It was inspected by a Hyundai service department in August of this year after making a knocking noise and stalling continually. It was diagnosed by the Hyundai service department with the same exact issue the sonata has which is covered in the class action suit, but our dealers request for a new short block was denied by Hyundai. There are metal shavings in the oil valve, and also in the oil pan caused by shearing from the crankshaft. There appear to be others with the same crankshaft issue that own Elantra models as well. Please see above attachments. My concern is that the same faulty deburring process that was used on the sonata's crank shaft may have also been used on certain Elantra's during the same timeframe. I also have receipts of all of my oil changes. If there is any information that is public knowledge about this deburring process that might have been used on other engine models or if you have any suggestions on how to proceed, I would appreciate it.

The first trouble started when I was driving on the highway at 60 miles/hour, my car started slowing down and would not accelerate. I had to drive at the speed the car would choose to run and in a few minutes it would work fine again. But this kept happening when I would accelerate the car on highways and I took it in to the dealer who said it was sensor problems. Engine light comes on when I use air conditioning, or use the head lights. Car will randomly not turn on although battery is new and makes a humming noise as I turn the key.

Engine ticking. Brought it in and they informed me I need an engine replacement. They also informed me if I do not get the engine fixed and continue to drive it, it could stall and or potentially blow up. Vehicle is under 100K miles, however I am second owner, so it is not covered under warranty. I do have all of my service records, I definitely maintained the vehicle so there is no reason to have to replace the engine on my behalf. Have not gotten it fixed yet as I do not have 8K laying around to do so. Hyundai needs to recall their 2012 Elantra engines as it is a manufacturer problem.

Elantra with 1.8L engine developed an engine "ticking" noise at 60K miles that developed into a "knocking" noise shortly there after. Main rod bearing failure. Had to have engine short block replaced. Vehicle had scheduled maintenance that included oil changes more frequently than required. Engine would have destroyed itself and stalled if continued without repair. Limited search on internet showed many other similar complaints. Sounds very similar to NHTSA recall NHTSA reference #15V568000 on Hyundai sonata with 2.0L and 2.4L engines.
