2018 Hyundai Elantra Driver assistance Problems

The dealership replaced my engine and spark plugs when the pistons were grinding metal causing a catastrophic failure in November of 2024. In July of 2025 I started experiencing the same issues and the dealership stated that Hyundais ignition coils have a high rate of failure because they changed the design and used my old ones from my engine replacement. It is now I brought my car into the dealership July 18th and they stated that was their best guess but they didn’t now forsure. I was never informed of the high rate of failure until I was experiencing it.

I was driving about 45 mph when the car just turned off the first time. I was able to put it in neutral and start it back up to get to the side of the road and it died on me again. I was about 30 feet from my destination at this point so I got it where I was going and turned it off. When I turned it back on it was making a terrible knocking/grinding noise. It didn’t have a drop of oil in it (about a thousand miles after my last oil change mind you) so I put oil in it and started it again and the sound quit. I went to drive it and it died before I could accelerate to a decent speed, got it cranked and rolling again and it slowly got up to 40 mph, but the second I started to slow down again it would die. So I had it towed to my mechanic who at first thought it was because the timing chain had a lot of slack in it, assuming it jumped time so he changed that, but it was still dying. He ended up finding the cause to be the exhaust cam sprocket? I’ve never heard of this before but I do know that ever since I bought the car 3 years ago it never felt like it would get up and go whenever I hit the gas. Since I picked it up from being fixed, this thing zoom zooms everywhere now! But it is still using an ungodly amount of oil between oil changes.

We own a driving school. My husband was giving a road skills test for a student in our 2018 Hyundai Elantra. For unknown reasons the car rapidly accelerated. He told the driver to get off the accelerator. She said she was not on the accelerator. He looked over and her foot was on the brake. We have an instructor's brake and by pressing it my husband was able to overpower the Elantra accelerator They missed another car by inches, but he was able to stop the car. They continued down the road and the car's rpms where high. He tested the car by putting the transmission in neutral, The car revived but the student's foot was on the brake. They continued to the office using the instructor's brake to control it. After the car was shout off and restarted It never had this same issue. We just brought it to the dealership for inspection of problem. Our mechanic looked at the car but could not find a reason for the problem.

While driving at any speed, vehicle momentarily does not respond to any gas pedal input. Driver presses on gas pedal but no change in speed, no rpm change no warning lights on dash. After a few seconds vehicle responds again randomly. Puts driver at danger due to not being able to same speed as traffic very dangerous!

My headlights on left side (low beam)and right side (high beam) have each burned out three times. My high mounted brake light has been replaced at least five times as well as my left and right brake lights. Now both of my tag lights went out and a right tail light. Also brakes keep grinding even after I replaced pads and rotors and NTB National Tire is telling me it’s in electrical braking system or calipers. My car had 94,000 miles on it and I’ve never had any car have caliper problems with low mileage.
