I was driving to work when a warning showed up on my vehicle. The warning message said: check hybrid system, turn off engine. The check engine light came on right away and another like shaped in a triangle form with hev written inside of it came on as well. I pulled aside and turn off the engine and call Hyundai. I was told they do not have a remedy for the engine recall yet, and they asked me for $9444 to fix the problem it's not their problem even though they have the recall on the engine.
2016 Hyundai Sonata hybrid ignition issue the engine is rattling while idling and under acceleration and the check engine light is coming on. Believe it is an issue with either spark plugs or ignition coil. Service dept said both components looked free of damage upon inspection.
During long distance driving once the vehicle is stopped for gas the hev warning light comes on. The car will not re-start for 15 -30 minutes. Once restarted the check engine light comes on. This has happend 3 times. The first two the thought was a long distance drive in the heat of summer. This last time it was fall/winter so the hypothsis of summer heat was thrown out the window. The most recent time the gas mileage went down drastically and the voltage for the electric system was acting erratically. The check engine light was on for 2 days but the car was only driven to the dealer. The dealer quickly found the problem and repaired under warranty "open recall". The car has not been driven any long distances since. The diagnosis was "main relay/power relay/cable (20-01-003h) caused by t4m. Power relay module melted at relay" installed 37583-a8000-qqh: relay-high voltage main, 37514-g0000-qqh: relay assy-power, replaced power relay assy module per campaign "warranty" hope this information helps others. . . . Hope this is truly the fix as it is an "open recall" that should be a recall". Glad this did not cause a fire.
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.

While driving the car at highway speeds, the car and engine start to shake. The shaking impacts the steering wheel and drivability of the car. The car loses any acceleration power and the check engine light comes on. The issue usually lasts 1-2 minutes. Afterwards, the shaking slows down and stops, then the check engine light turns off. When I took the car back to the dealership, they said the engine needed to be replaced. 5 months later we are the same issue is happening.
I stopped for gas and when I attempted to start car an alert came across my screen saying car has a hev issue and check engine light. I would have to wait for 15 to 20 minutes for my car to start again. I was assuming it was bad gas but mechanic confirmed that it wasn't a bad gas issue. I went to the dealership and they said it's a potential electric issue that my warranty does not cover. I had yet even exceed mileage above 70000 miles. I believe this is an issue that is an inconvenience to me and other drivers because it is starting to happen more frequently. This could be a father for anyone in a urgent situation and need to be able to activate the car to leave immediately. Thank you for your consideration.
