Got an engine light at 37K miles. Took the car to dealership initially told was vcm motor, replaced, left dealer and light came back on, told they forgot to update software after replacing vcm motor, left dealer and light came back on. Went back to dealer for third time and after they called Hyundai engineering the discovered that the entire manifold needed to be replaced as it was somehow wedged into the engine. Was covered by warranty as should be. This somewhat helped my acceleration issues but was told it was a safety issues because if anything from the plastic manifold broke off in engine it would cause the rods to bend and could cause engine to seize and catch on fire.

After a stop at a traffic light I attempted to accelerate and the engine stalled out. Attempted to restart and on the second attempt it started and as I accelerated it stated to buck as the transmission made sounds while the gears were struggled to change. As I gave it more gas they slowly recovered over the next mile. Took it in for a check to Hyundai on 8/29/18. Checked out ok with no reason.

It initially started around a couple of months ago. I was driving and my oil light came on. I took it to the dealership thinking it was not topped off correctly since the last oil change 2,700 miles prior to the light turning on. The dealership says "there was no oil on the dipstick." Performed an oil consumption test. The most recent report showed that my "oil was 3 quarts low". the dealer advised me to trade the car in since I do not have the warranty on my car anymore to fix it. I just bought the car last April. I have maintained the car with it's recommended services and use full synthetic oil. I drive a lot of highway miles, but I take care of my car since it is an investment. I cannot afford to finance another car. Thank you.

On my drive home from work, the car started smoking. I was initially driving on a highway, but had just turned onto a side street. The smoke began to get worse and was coming into the cabin. I was able to pull over and as soon as I could get out of the car, the car completely engulfed into flames. Hyundai was unable to determine a cause of the fire.

This car cut off at a stop light with no warning at all, there is always hesitation and does not want to pick up speed. May car has been to the dealership many times and they can't tell me whats wrong and has had an fuel injection replace, gas treatment cleaning, and a senor replace. I fear for my life and family every time I have to drive my defected car the dealership doesn't care about my safety. I have drove the car with the service manager and technician and they felt what I was feeling and the problem continue.the hesitation occur on the city street and highway.

My cars engine has completely shut down while driving several times. If I turn the car off and restart it fixed the issue for the time being. The second issue is my steering wheel has locked while I've been driving making it impossible to control the car.

When depressing the brake my car is making a clicking noise. Went to the dealer and he said it is normal. Previously it was little but now days it is making loud noise while driving. When we depress the brake and try to change the gear from P to D the gear rod is making same clicking noise. When read forums I heard that it is the problem with the solenoid but the dealer does not want to do because he has to do it for free. When asked the dealer he said that it does not come under warranty. Now the noise is really loud and no one is helping me out.

While driving, my engine light came on and I got an alert that there was an issue with the engine control module. I made an appointment asap but continued to drive the car until my appointment in 4 days. Later on that day, I was I fully stopped iat a flashing yellow light, then attempted to cross over a lane of traffic. The car moved but would not accelerate past 12 mph - almost causing me to be hit by oncoming traffic. I had to turn my hazard lights on and coast until I could pull over. I called Hyundai and they expedited my appointment but claimed there are no active recalls. However the technician said that there is a "campaign" and that he replaced the part. Their website says this: Sonata 2.4L ECM update & vcm (16-01-064) I almost got hit by oncoming traffic because of this ECM issue and I think that Hyundai is putting people in danger by downplaying the seriousness of this issue. It should be a recall - not a "campaign" and they should be required to notify car owners to get this issue resolved asap. It could be a matter of life and death.

We were driving along at 70 mph and suddenly the engine stalled and electrical gauges all turned off for 15 seconds, meaning all gauges went to the left like when you turn your car off. Dealer said that they found nothing wrong. They said to let them know if it happens again"???????????". I told them that how could we let them know if we are both dead.

I was driving the car and the car started spitting and did not want to go. Then white smoke came out of the tail pipe. I cut the car of and waited in traffic with my baby in the car, then turned the car back on. The engine light came on and the car drove like it had no energy. I was on my way to my new job for the first day.

Every time I release the brake pedal after sitting at a long red light the car shakes and shudders, sometimes really hard, and sounds like it's choking for a few moments before I am able to accelerate. It sounds and feels and acts as though it is going to stall but it has not yet. The effect does* happen when the air conditioner or the vent are being used; only when those are off. It varies from mild to really strong. It took multiple trips to the dealer for them to determine that it is normal not just for my car but for all 2016 Sonatas. It is a feature where the transmission shifts into neutral at long stops then re-engages in drive when the foot is lifted from the brake pedal. The purpose is said to reduce engine load. I think this is a safety concern is because when a driver removes their foot from the brake and the car's brake lights go off, it is a signal to the car behind them that they are about to go. But the wait time required for the shaking and sputtering to stop before the gas pedal will work results in 'mixed messages' to the driver behind, thinking that you are ready to move forward but you're not really ready yet, and may result in a rear-end collision. *detailed time line attached *official communication from corporate attached.

ECM issues. Car had ECM problem and lost power. Went into the dealer, and they said they repaired it. Didn't even make it home from the dealer and it happened again. Back to dealer and they said again it was repaired. Car had 10,000 miles on it at the time. Less than 3,000 miles later, it happened again - car completely shut off on the highway. Complete loss of power. Dealer claimed it was the same problem and "fixed" it with a software update. Now scared to drive it - considering lemon law? three problems in 6 months on a brand new car, and same problem every single time.

While driving 65mph at 10pm on a the interstate, I heard a pound "thunk" and thought I had a tire issue, so began to steer toward the emergency lane. I quickly realized I had no power to accelerate, no power steering and the dash was blacked out...car was dead. Only ever thing working was radio, emergency flashers and dome light. Door locks did not even work. Called for roadside assistance and car was towed. I have no further information about the car's disposition as it was a rental. It was terrifying and could have ended catastrophically in serious injury or death. The reason I am filing this report is to insure it will be investigated thoroughly. I did report it to Hyundai.
