general problems of the 2017 Hyundai Sonata - part 2

Car caught fire while driving on the freeway. Driver had only been driving the car for about 10 to 15 minutes. Got on freeway from downtown houston and was on freeway for less than 10 miles. Witness said car was on fire under vehicle in the rear of the hybrid vehicle. Driver pulled over to feeder of fwy and car would not go into park so he turned vehicle off and exited vehicle. Driver saw car was on fire and ran to safety.

Had open recall ,, an ecm update and wile Hyundai in columbia CT. And after it was done the car worked fine for about a week , now I'm lacking acceleration for miles per gallon has decreased 50% burning gas quickly plus is burning about a quart of oil a week, but there's no check engine light, change the spark plugs and air filter still the power has decreased 30%. I noticed that decrease in power when entering on to a highway and I tried to accelerate into traffic but it did not have any power at first until it started bucking and then it's finally getting some momentum. The spark plugs were changed but the problem still persist! still at this time the problem is unknown to me.

My 2017 Sonata has stalled while idling in drive. The car completely stopped at a red light; rpms dropped and it stopped. Prior to this happening, I had complained to my local dealer that when idling, it has dropped in rpms and felt like it wanted to cut off but did not. . . Until today. At that visit, I had the fuel system serviced, as they thought that maybe this would help. That was approximately 2 weeks ago and now it has completely stopped at a light. I am taking the car back in as I am not certain what else it could be. . . Maybe mass flow sensor? I have seen where the 2018 Sonata had a recall regarding hesitation/stalling issues and now I am wondering if the 2017 has issues as well. I am afraid to drive it in heavy traffic as now it may cut off on me and not start up again.

The engine is stalling and shut off at a traffic light. Using oil on a weekly basis. Gas mileage is not efficient at all. No warning the oil pressure is low. The latch on trunk had to be replaced weeks after I purchased the car but I had to replace it cause it would not shut. And now there is a recall.

My car won't turn on when I turn the ignition key. It stays silent no click or anything indicating its trying to turn on. The vehicle is always stationary when this happens. It randomly does this and rarely it turns on when I turn the ignition.

While driving on the highway, a notice was shown on the dashboard that the hybrid system and cruise control system were no longer functional. The vehicle then started to accelerate, uphill, without the gas pedal being engaged. The vehicle was taken off the highway and when coming to a near complete stop the vehicle stopped working completely. After restarting the vehicle and driving it to a safe place to park a notice indicated the breaks were no longer functional. The car was subsequently towed. The vehicle has had numerous repairs since and is still experiencing the same issue(s) as of 12/05/2019.

For some period of time, now, I have lost engine power, while in motion. It happens sporadically when I cannot press the gas pedal for continuous motion forward. This has been happening on a highway as well as city streets. It pauses when I press the gas pedal and the delay is momentary. Lately when starting the car for the first time in the morning I hear continuous knocking until I drive for several miles, then it dissipates.
