It was smoking from the engine, I immediately stopped the vehicle. My safety was put at risk immediately while being in the vehicle when the air bags deployed hitting me in the face and causing my face to swell. The safety of others was put at risk due to others being right next to me and putting others at risk of engine blowing up. Yes, the vehicle has been inspected by police. There were no warning signs on the vehicle.

While stopping at a major highway intersection on [XXX] for a red light vehicle stalls and will not start back up while everyone else continues at a 55 mph mile an hour passing me on each side! This happened more than 6 times . While you’re stuck in intersection,you have to keep trying to start the car eventually it will start . Apparently it is EGR valve and is a very common problem. IT IS NOTED IN THE common problem for this year making model and the repair cost is in the range of $1600 even the dealership said it is a very common problem. They have been experiencing it.

If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Hyundai Sonata Hybrid verdict →
