According to the Hyundai Dealership, located in Corona, CA, the Hyundai Elantra's are known for the ignition coil to go out. This is also not covered under warranty and list below of why it should be: This can cause Engine misfiring in a vehicle whose ignition coils have failed. Trying to start the engine of such a vehicle will result in engine misfiring that sounds like a coughing, sputtering noise. When driving at high speeds, jerking and spitting will be seen in the behavior of the vehicle. A vehicle with a failed ignition coil will also result in vibration when it is idling at a stop sign or light. Driving with a faulty coil pack can damage other components of the engine. Also most cars will register a faulty coil and immediately stop gas feed to that cylinder. However, damage may be caused if the fault isn't registered by the PCM and the dead cylinder continues to receive gas. …
This is just to inform the issue that I faced with my car, Hyundai Elantra 2017. The incident happened twice. I was driving once on an interstate, luckily was driving very slow (due to traffic), when I accelerated a from a halt position the car started to jerk and the engine light came up and the car stopped. I then took the car on the shoulder and turned on the car after 5minutes, luckily the light went away and was able to drive back home slowly and safely without any problem then. Thought it's just a one off situation. This again happened when I was driving in the city; Stopped at a signal and was starting from stop position on a signal when the engine light shows up again and car started to jerk again, with that on I slowly drove 1 mile back to home. The next working day I took it to the dealership to get the car checked. …
My car stalled twice while driving on my way to work and had a weird knocking sound. I brought this to my local mechanic and they believed it was Rod Knock cause by premature rod bearing failure. They said this is a common issue with Hyundai 2.0L 4 cylinder engines and told me to reach out to a Hyundai dealership. The first dealer I called said if it was the rod bearing it would be covered under an extended warranty. That dealership couldn't get me in for 3-4 weeks so I called the dealership I purchased the car new at. They said the same thing that it was a common issue with the 2.0 4 cylinder engines and said they could get me in in less than a week. I paid to have my car towed to them on Friday and they called me this morning confirming that it is a worn rod bearing and informed me I would need a new engine. …
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 the safety of others were put at risk when it stalled out while I was deaccelerating on an exit ramp that merges with three other lanes. I could have been hit from behind by others exiting the interstate highway or hit on either side of my car from drivers switching lanes at that junction. It stalled out the same day in the middle of a roundabout, where drivers yield and merge at 30 mph. …
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 riding well. The next day, the check engine light went on again and so I brought it in to my mechanic. He said that there were metal fragments/shavings in my oil that were clogging my engine, etc. He said that I need a new engine and said he had several other Elantras with the same issue and that I should take it to a Hyundai dealer because of all of their recalls/Class Action Lawsuits which extend warrantees, etc. …
The vehicle has experienced ongoing powertrain and electrical malfunctions over several months. The most common symptoms include being stuck in 4th gear (limp mode), complete loss of RPM and speedometer readings, and illumination of the check engine and ESC lights. Most recently, while traveling at approximately 10 mph, the vehicle experienced a sudden loss of both acceleration and braking. The brake pedal became stiff and unresponsive, and the car had to coast to a stop without driver control. This posed a serious safety risk to myself and nearby traffic. These issues have persisted across multiple service visits to Ricart Hyundai in Groveport, Ohio. That dealership has replaced the crankshaft position sensor three times, the powertrain control module (PCM), and the battery, but the underlying problems remain unresolved. …
