After a period of driving, which is random at best, the check engine light will appear and the vehicle will start to shudder and lose its ability to accelerate. This happens when the vehicle is in motion and happens both on the freeway at high speeds, as well as on city streets in low speeds. The only way to get this to stop is try and get to a safe space of the road and turn off the vehicle. It is very scary and dangerous especially in southern California freeway traffic and in mountain passes as you lose the ability to maintain speed in the middle of traffic. This could very easily cause an accident. This has happened to me on 7 different occasions over the past 2 months at random times.

The automatic transmission on the 2016 Hyundai Sonata hybrid went out on the car Oct 31, 2019. My wife was driving the car, when she lost drivability of the car. The car would not go, she was able to park it on a side street. She restarted the car but would not go into gear, the engine was running. The car was towed to the closest dealership, when scanned, indicating of a transmission problem. The car has been at the dealership since Oct 31, 2019 with no eta of when a new transmission will be available to repair the car. At this point I can not sale the car because it needs a transmission. Hyundai needs to give a date when the transmission will be available. The dealership has no time frame when they will get a transmission from Hyundai.

Also, there was an abnornal burning odor and a ticking noise was detected. Furthermore, the maintenance warning indicator was illuminated.

I was driving my 2016 Hyundai Sonata on the interstate at approximately 65 mph, with a semi-truck bearing down on me. As I accelerated so I could pass the car in front of me, and get out of the way of the semi-truck, my car lost all acceleration (at about 4000 rpms) and would not go at all, in fact it started slowing down. I let off the gas, because it wasn't doing any good, and as the rpms went down, to about 2000 rpms, my car slowed down to about 55mph before I could give it gas again and get it back up to the speed of all the other traffic on the interstate. There was no other warnings before this happened. It was a very scary and dangerous situation. Luckily, the semi-truck was able to slow down before it hit me. The next day the check engine light came on, so I took it to an auto parts store where it was put on a computer and it came back with the code "P200A", which is the "bank one intake manifold runner controls". the report stated that "this has been seen before on cars like mine, and that the most likely fix was to replace the variable charge motion actuator (vcma)". I googled this issue to see if there was a recall on this part for my car and found quite a few posts and comments of this same thing happening to other people. My car has 93,000 miles on it, but in other reports I saw online, the car only had 11,000 miles on it. This needs to be recalled, it is a safety issue!

Car hesitates on acceleration on an inconsistent basis. The rpms increase quite a bit before the car accelerates. Usually at lower speeds or after stopping at a traffic light. Car has dual-clutch transmission that is part of class action suit.

Yesterday evening 14oct2019 vehicle was unable to power up, hybrid system hev warning light went on as well as the check engine light. Tried several attempts to get the car going. Finally got it going. Brought it to the dealer for diagnosis 15oct2019.

Car shakes erratically when trying to accelerate and has no power after hitting accelerator. It struggles to get any power to get going after being stopped at a red light. Gear changes get stuck and I have literally been stuck in middle of intersection while doing a legal U-turn in a busy busy la intersection with my 10yr old in the back seat and the only way to get out of the situation was to turn car off and turn on again which poses a major safety issue for both my daughter and myself. Took car in to service last week and they supposedly fixed issue but one week later here we are with same problem. Service told me it looks like solenoid is going out. Which seems strange for a 2016 car with only 27,000. So if this was the case why not change it before it was sold to me. Also car had prior issues before it was sold to me according to service. I smell recall"??" I have no documentation but the dealer has all supporting paperwork.

I went into the dealer to get an oil change on 3/14/2019. The dealer chose to do a factory recall 50hyz. Soon as I left the dealer my car started stalling on 495 North towards tyson corner in Virginia, jerking and lost drivetrain power. I could get to 60mph and the car wouldn't respond after that. I took the car back to the dealer. I was told the software updated bricked my Sonata. The dealer told me they will order the part and will come in 3/21/2019 which is today. Only to get a call saying the part is on back order into May. My question is why isn't holding Hyundai accountable for this" my car isn't the first one to get this software update so if Hyundai knows this software is going to brink peoples car how in the hell are they allowed to keep doing this recall when they have no clue when the part will be available"

Engine is making weird rattling sound on acceleration and burning oil too much. Prior to 3000 miles oil change, checked dip stick and indicated no oil. Low oil on dashboard did not came on. Believed that the engine consumption is out of limit. Rough idle and acceleration hesitation was notice.

When I drive my Sonata, sometimes the gears do no switch. I can drive on a flat or inclined surface and it will act up. We've taken our car several times to the dealership for diagnostic testing to see what's going on. But when the car is connected or the serviceman drives the car, the car will switch gears and nothing is found on the diagnostic test. We currently driving a few states over and our car is not switching gears at times, affecting the gas mileage. My husband and I will decelerate until gears switch and then accelerate again.

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.

Loss of acceleration between 3-4 RPM.. hard acceleration..loss of acceleration before shifting between 60-70mp.. then slowly accelerates. Major problem if on highway where you must speed up but car not quickly shifting gears and is running too slow.

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.

Driving at highway speeds once the engine is at full operating temperature there is a harsh surge during down shifting at 35 mph ( almost as if I were down shifting a manual transmission or hitting the brakes) this causes the vehicle to slow much more rapidly than expected causing my head and body to move forward in the car. It is extremely distracting and I am nervous it will cause an accident.
