   When driving at low speeds(20mph and under) vehicle stalls. It appears to happen at random. It makes driving pretty dangerous for other vehicles that would not be able to tell the vehicle has stalled and hit me at low speeds. All electrics stay on, there is no check engine light. The problem first appeared after ignition lock was broken, even before replaced it started stalls at low speeds, seems to possibly happen more after engine is warmed up.

   My 2017 Elantra with 107,000 miles (it has a 100,000 mile powertrain warranty) on it has just experienced the same issue as all of the other Hyundais that have been recalled. I was driving on Xmas evening 2024 and started hearing my engine making noises I had not heard before when excellerating but then they would go away. On my way home the check engine light went on for a couple of minutes but then went off and I was able to get home although the car did not seem to be…

   Since January 2024 I have had issues with my car starting due to low oil. I just had an oil change so I knew something was wrong. The repair shop stated there were no leaks and put more oil in and said that sometimes the car will not start if there is not enough oil. February 2024 and the car wont start again. Filled it with oil and took it to the shop again. They stated that the engine is eating the oil and to take it to the dealer for a test. Since then the car has turned…

   The car randomly dies on de-acceleration. It gives no warning and I have seen online this is a known issue with this year/model. I have 55,000 miles on it, it's been regularly serviced. When I got to slow down then start to accelerate it shuts off. I've nearly been hit multiple times going to merge from a stop. It's very dangerous. I've replaced all 4 spark plugs, all 4 ignition coils, air filter, cabin filter, oil filter, PCV valve and I've only owned it 6 months. No engine…

   Car will lose power and quit suddenly on the highway with no warning lights. It has happened twice in the last month on a trip both times. Light’s low beam randomly won’t turn on either but high beams work. Had it into the Hyundai dealership and another mechanic shop but cannot find the problem.

   For the past two weeks, the car has intermittently stalled out and the engine, oil, and battery lights come on. The dashboard electronics and radio stay on. When this happens, I have to put the car in park and turn it off, then turn it back on. It has restarted immediately each time and drives normally. It has stalled out multiple times in a day, but not everyday. I took it to my mechanic twice to pull an error code from the warning lights, but he could not. My safety and…

   It has happened multiple times over the years that when I press the gas pedal to go, the car does not go or does not accelerate. Several times it has happened when attempting to make a left turn. So the car goes enough to get me in the way of the intersection but not very fast so I have been nervous that I might get hit. Generally stomping the pedal a second time gets it to move, but it is unnerving. I'm including the most recent date this has happened in the next part.

    My 2017 Hyundai Elantra has problems with the ignition coil packs, sensors and engine. The car stalls at lights. It idles very rough and shakes when driving. Acts as if it will stall on the highway and extremely slow acceleration. Dealer told me there was metal parts in my oil, oil was thick sludge and that I never changed the oil. False and I have the oil change receipts to prove my oil changes. I have taken the car to the dealer numerous times for the stalling and no…

    Since buying my vehicle new, it has had three ignition coils fail at different times. The car begins to shudder, rough idle, not accelerate and all of a sudden just will not respond to giving it gas. This happens at any speed therefore it is a danger especially entering or exiting highways or switching lanes. It has been unpredictable. The check engine light does come on some of the time as this problem is occurring, not before. The dealer replaced the first two coils (51,…

    I’ve been having problems with my timing chain and power train for over a year. Got the timing chain fixed and now all i’m seeing is new problems with bad ignition coils and spark plugs and transmission problems. I’ve only had this car for 4 years and keep the maintenance up to date.
