I was driving my 2012 Hyundai Elantra and it suddenly stopped. I took it to be checked out and it has an excessive oil consumption issue which can cause engine failure or a fire. Hyundai refuses to acknowledge the issue or fix it. After doing some research I see that this is a common problem with this car. I have to check my oil every 1000 miles and many times less than that and refill it. They should be held responsible and fix the issue. There should also have been a recall considering not only how dangerous this is, but also how many people are experiencing this.

Since day 1. Brakes have failed. First recall took years. They -??updated my software -?? brakes still failed. They failed to believe me -??Couldn-??t find a problem -?? there-??s no warning lights no nothing. Out of nowhere. The Brake goes to the floor. Makes a grinding sound and your either going towards on coming traffic or a ditch. Brakes failed at numerous intersections. How I-??m alive is beyond me. The best part, either the seat belt is too baggy or strangles you there-??s no in between. My entire steering system is junk. wasted money on tires alignments brake pads brake censors. Dealership has another recall on these brakes with no remedy. I-??ve sadly driven this car over 10 years with failing brakes. I drive with my right hand on the e brake ready to yank it at any given times. I-??m honestly traumatized by this car. Engine and transmission are junk. Nightmare

On [XXX], I was driving on the left lane of [XXX], between [XXX], traveling [XXX], in Oakland, California. I had only driven for a few minutes after leaving work. After braking at a stoplight, my 2012 Hyundai Elantra stopped functioning and stopped on the road while driving. The "check engine" light went on, the "check battery" light went on and a "check fluid" light all went on at the same time for over 10 minutes. During those 10 minutes, I was unable to start the car. I put my hazard lights on and desperately called 911 and AAA. I continued to try and re-start the car. After 10-15 minutes, I was able to get the car started and pulled off the road. I was later able to drive home. I later had the car evaluated by a mechanic and he could not find a reason for my experience. The battery was replaced within the last 6 months, oil was changed recently and an engine coil was recently replaced. We get the car repaired/serviced regularly. I strongly suspect that my experience is related to Hyundai Recall 251 / NHTSA Recall 23V651000. This is a very serious safety issue (e.g. "engine could catch on fire while driving or parked...") and Hyundai has so far not been appropriately responsive about my safety concerns. The Recall was issued in September of 2023 and no remedy has been issued to date (as of 2/16/24). Hyundai owners should not be expected to just keep driving cars that are at risk of randomly catching fire while driving or ceasing to function while driving on a busy road. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) The contact wants to follow up on this complaint.

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 [XXX] 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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 [XXX]. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

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] -??
