On April 23rd when traveling from Jamestown, NY to to Fredonia, NY my car started and it seemed to be running rough. I shut the car off, and restarted it. It still seem to idle differently. Drove home, stopped I planned to stop to see my youngest daughter who resides at 8450 Fredonia-Stockton Rd. 600 feet away from driveway, car began to chug and the engine light came on. I put on the Hazard lights and pulled to the side of the road. A pick up truck behind me was speeding up on me, he then swerved, and crossed the line into oncoming traffic. Breaks were screeching I was terrified there was going to be an accident. Called AAA, car was towed to Ralph's Penzoil in Dunkirk. Ralph replaced the coils. The car no longer chugged, the engine light was not on, but it sounded extremely loud, like a Diesel Tractor. Ralph said it was a hole in the muffler. I brought the car for a second opinion to Arkwright Towing and Larry said it was engine noise. Either the bearings or camshaft. He said there was no repair, I would either have to replace the engine or sell the vehicle. He cautioned against replacement as this model and make of Hyundai has had many engine recalls and problems. I then stopped driving the vehicle and used my mother's vehicle, as she no longer is driving after being discharged from the hospital. I finally had the chance to take the car to Hyundai Shultz in Lakewood, NY. I had brought the car there a few months prior, because it seemed to be running loud, especially in the morning. The Service department fixed a few recalls, but noted nothing wrong with the way the engine sounded. At this time the Hyundai dealership in Lakewood, Shultz my car continues to sit. Hyundai USA has refused to help replace the engine, as they state I do not have an extended warranty. While there have been hundreds of engine safety recalls on this make and model, just not 2012. Hyundai has closed my case, with no solution or repair.

Engine shuts off sporatically, sometimes 4 times in an hour of driving at low speeds. I could easily be rear ended in light traffic when the engine turns off. The problem has not been confirmed by anyone. I've Google the problem on different forums and many Elantra owners are experiencing the same problem. There are no warnings

This report was submitted PREVIOUSLY on April 5, 2023 with no response received by me: My 2012 Hyundai Elantra Limited engine began making a tapping/ticking noise a few years ago. The noise became louder and then I discovered that my car qualified for the EXTENDED POWERTRAIN WARRANTY which was granted to any 2011-2016 Hyundai Elantra owner with 1.8L Nu Engine that a class action lawsuit brought against Hyundai Motor Corporation. I was never notified by Hyundai but rather a mechanic that I brought my car to that was aware of the campaign. I contacted Hyundai and was told to have the engine diagnosed by my local Hyundai Dealer. The results of the diagnosis were submitted to the Hyundai Motors Corporation Warranty department and my claim was denied as I was told that my mileage and years were past the qualifying criteria. I had brought my 2012 Hyundai Elantra Limited to the Hyundai dealership that I had purchased the car as certified used Hyundai in 2014 for the engine diagnosis to determine if the engine noise was related to the Extended Powertrain Warranty granted to owners of any 2011-2016 Hyundai Elantra with 1.8L Nu Engine. The borescope results and photos were sent to the Hyundai Motors Corporation Warranty department and it was confirmed that my engine did indeed have the "piston slap" problem as outlined in the class action lawsuit and all four cylinders were severely scored. Upon contacting Hyundai to request the borescope video and photos that I had paid $200 to the Hyundai dealership service department for the diagnosis, I was told if i wanted the video and photos I would have to hire an attorney to obtain them from the Hyundai warranty Department! I was never notified of this "secret" campaign! Needless to say I am extremely unhappy about this. I deserve to have this engine fixed under the extended warranty that Hyundai failed to notify me about. This is UNREAL! Please tell me what can be done here. Thank you, Douglas E Stevens

Please find below a description of the malfunction in my Hyundai Elantra, as this is the reason I'm requesting inclusion in a recall. Since the week of Thanksgiving 2022, I've had several instances of my vehicle stalling without warning before engaging the transmission; for example, my car once stopped moving completely on the freeway while entering the onramp at 55 mph. Since then, the problem has only gotten worse, stalling up to seven or nine times per week. Because of the severity of this issue, I-€™ve had it inspected multiple times and would gladly submit it to another one if requested. Obviously, a defect of this magnitude with no obvious cause not only puts me at risk as the driver, as I can-€™t prepare for a sudden stop, but all road travelers around me are also subject to this issue. As you know, a sudden halt could lead to collusion involving numerous people. To date, an independent service provider has not been able to identify the issue or recreate the problem, as it occurs randomly with no warning lights or signals to prepare me for what-€™s about to happen. Should you need further details, I may be reached at susanramsey1@gmail.com.

Car has been properly maintained for years. No accidents or known major issues. Suddenly the car would not start one workday morning. The tow truck driver was unable to start the car; towed car to repair location. Nationally known major service station said the car was low on oil, they filled with 2 quarts. No prior oil problems, no oil or engine idiot light on dashboard was lit, no oil puddles/stains. Car returned to owner, on short drive home, the engine trouble idiot light turned on. Used code reader to find P0014 - cam shaft positioning error code. Brought to local service station, was told car needs a new engine. No outstanding recalls. Recent newspaper article stated there have been problems with 2012 Hyundai Elantra engines. Maybe locked engine is related to other known issues?

All of these issues occur in any weather or if the car is warmed up or not. They don-€™t occur all the time but about half the time. -From a standing stop (like when entering an intersection or turning on to a road) lightly pressing on gas pedal will get car moving then in 2-3 seconds it will stall out for 2 or 3 seconds, almost to the point of the engine stopping. At that point, moderately pressing on the gas again will cause the car to accelerate suddenly & forcefully. It is terrifying when a car is coming at you & you don-€™t know if it-€™s going to start accelerating or just die. -Driving and maneuvering in a parking lot is quite a risky adventure. At these slow speeds the car will randomly stall, lurch, hesitate & accelerate suddenly & forcefully with just a light touch on the gas pedal. Not the best performance when trying to park or maneuver around closely packed cars. -I have taken the car to the dealership at least 5 times to remedy this problem & they either said this behavior was not detectable or it was operating as designed. I have documentation consisting of service invoices. They obviously weren-€™t being truthful, considering the Recall & Class Action Lawsuit that has subsequently been issued dealing with this issue, revealing that HYUNDAI knew about this problem. Can I finally get my car to operate properly & SAFELY? [XXX] -€ƒ THIS IS THE TRANSCIPT FOR THE PHONE CALL FROM HYUNDAI ON OR AROUND 9-14-21 ON ANSWERING MACHINE (It didn-€™t identify which recall it was referring to): This is the HYUNDAI Recall Resolution Team contacting you about a safety recall on your HYUNDAI vehicle. HYUNDAI has decided that a defect which relates to motor vehicle safety exists in in your vehicle. Please do not delay in contacting us. Your HYUNDAI dealer will fix the recall at no cost to you. This free repair should take less than an hour to complete but your HYUNDAI dealer may require your vehicle for a l INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Just bought the car a couple weeks ago for my daughter. The car was parked in a parking lot and would not start. Tried jumping it. Changed battery in key. Gas tank was full. Finally looked on internet and finally looked on line and found a lot of others had the same problem. They said to push the car from the rear. We did and it started. Afraid my daughter will be stuck at night leaving work.

My 2012 Hyundai Elantra would stall at stop signs and lights. It would stop and start again.. I went to Hyundai to check it out and they said it was the fuel pump. The next day I was driving on the highway and turning off the highway my car stalled out and when I tried to pull over on the side of the road the brakes were hard to press. Using all my weight I got it to come to a stop. It would not crank. I tried about three times to crank it while holding down the gas. It eventually allowed me to change gears really quick and take off. I made it 5 minutes down the road to the house but it stalled as I parked. Now it won't crank at all. For the last couple of weeks I've been trying to crank it. I've had the fuel pump, the spark plugs, the camshaft sensor, and the camshaft position sensor changed and it still isn't cranking

A few weeks ago, I was driving my 2012 Hyundai Elantra (114,000 miles on it) and it started to sputter and I could not accelerate above 20 mph and engine light came on. There had been a similar intermittent probelm prior to this. I had it towed to my dealer and ended up with a replaced coil pack on one cylinder. On 11/4/20, I was run off the interstate by a semi because as I entered the highway, I could not accelerate beyond 20, and then 40 mph and the tacometer regisered 0. I took car back to dealer where they said that the "tech reset adapt.values" ("valves" is what they told me verbally). Well I left with the car after the supposed "fix" and 1/2 mile from the dealership, the same de-aclleration occured, and this time when I went back to dealership the manager had the tech run the diagnostics on original problem on his ipad and tech said the coil pack was fine. The manager then had the tech run all system computer checks and the second time around, an error pointed to the crankshaft so they ran all the computer updates, which took a good 20 minutes, and said that likely fixed the issue. I thought the issue was fixed but today, two days later, I was driving the car and the engine just stopped in the middle of the street while I was driving. I restarted the car and drove it a few miles and I noticed again that the tacometer was not working. This is the 4th time I had to take it to the dealership. I asked them why they didn't run updates when the car is in for routine maintenance and he said they only do so when a problem is noted. The initial issue almost got me killed on the highway. And according to the dealership, other drivers of Hyundai vehicles are experiencing the same issue. Someone will be killed if this safety issue isn't resolved. The issue has not been resolved as of today, 11/6/2020 regardless of what prior svc reports upload states.

For the past several months I have had a reoccurring issue with my 2012 Hyundai Elantra. About 1-3 times a week, my car will not start. All lights, radio, etc. Work fine when key is turned to on/start position but car will not start. It makes one click sound and then nothing. Generally, if I keep trying it will eventually start. Sometimes it takes 10 minutes and sometimes it takes a few hours. Along with this, about once a week my car will shift gears hard. It is an automatic and otherwise shifts fine. I have had routine maintenance completed on time since I bought this car in 2016. I have brought my car to my mechanic several times in the last few months and he cannot determine the problem since the car does not do this regularly. I read online that it could be the neutral safety switch (range inhibitor) so I replaced that. The problem still exists. I contacted the Hyundai dealership from which I purchased my car and they have no answers.
