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, 576 miles and 56, 446 miles) under the warranty. The third coil replaced (78, 391 miles), they would not cover under warranty, nor would they replace the 4th coil as a precaution.

This is a very unsafe vehicle. There should be a recall!!!! This is a well known problem, yet Huyndai and NTHSA does nothing. How many people will be involved in an accident or killed before you do something? This vehicle has been having check engine light come on multiple times in past month. When it does the whole car shudders/shakes , and won't accelerate. There is also a knocking. THIS IS AN ACCIDENT wAITING TO HAPPEN! First time I took it in was to a Firestone shop as Huyndai had no opening for weeks. I drive 60 miles 1 way for my job, so couldn't wait for Huyndai. Firestone said it was misfiring, and that it was very low on oil. They couldn't get it to duplicate the incident, so couldn't figure out the problem. An oil change was done. Multiple times in next 2 weeks the light would come on, then sometimes go off with no other issues, but sometimes the same knocking sounds and shaking. I took it back to Firestone and they determined a coil needed to be replaced and a spark plug. And in that short of time the oil was seriously low again. These fixes were done. The next day after picking it up, same issues!!!! Firestone won't work on it now as they don't know what else to do. We have an appointment with Huyndai but not until Sept. 12th. What am I supposed to do???? Take a chance of dying every day to get to work? I can't afford a rental for the next few weeks until Huyndai can look at it. This is so unfair. Why haven't you made Huyndai recall and fix this very well known issue? Please help!

The brakes on this car are HORRIFYING. Sometimes the brakes shudder so hard that your body will physically lurch forward with the braking. (and this is only when braking from 45-50 mph, anymore feels like the car is falling apart) It feels almost as if the right front brake is ‘sticking’ causing the car to brake unevenly and stop later than it should. Sometimes I have to fully push down on the brakes to get it to stop all the way. Sometimes I will let go of the brakes and the car will slow down itself in a strange lurky way…. If I am going over 70 like on the interstate, and push on the brakes, they feel as if they cannot handle braking… The whole car, steering wheel, peddles and all vibrate intensly like the car is about to fall apart. and I’ve had many scary encounters where I have to glide my car out to the right to get the car to stop in time. I have taken into the Hyundai dealership multiple times. They always say nothing is wrong with it. I have owned this car less than a year and it is just now hitting 47,000 miles. The brakes just feel wrong. The car stability is almost nonexistant. I feel every bump or slight dip in the road, and the car follows them roughly. When braking while hitting a bump, I might as well not use them, as they won’t lock in until after the rough road. Scary car.

Hyundai avoids taking care of their cars by sending out general statements for techs to "fix" these issues but they never do they say I didnt hear it when brought in mulitple suspension electrical issues my husbands 2019 hyundai eletrical going out. The engine issue all they did was say didnt do it for me. They need to replace all these known issues it is braking down the whole vehichle for both of us. I believe hyundai is negligent in worrying about the cost of afull recall so they deny anything.I have videos documents, my car went from red gas to green random clicks deterioration. My hubsands car is the only owner engine shudders randomly they do a fake iinvestigation. Hyundai does not care if you die.

My 2017 hyundai elantra began to shake and refused to shift above 40mphs on a road posted 45. The engine light came on and the rmp gauge show that it was stuck at 2rmps. I slowed the vehicle and turn on my flashers and in my traveling to a safe pull off location. The engine light went off, the shaking stopped, and the car resume a normal shifting pattern. The very next day while traveling in the car the same thing occurred. I explained the problem when arrived at hyundai and while idling and waiting to the car person to check me in. The car began to do short shudders; this was directly witnessed by a car service employee. The 2nd cylinder ignition coil was replaced. In my second visit I was sure of what the problem was because I had experienced the same car symptoms several months earlier. Here is the problem this was second cylinder I have had to have replaced in about 3000 miles and several months; my car only has 25,0000 miles. This is a known issue on the repair form it states ecu upgrade.
