2016 Hyundai Sonata Hybrid Problems

EGR needs to be replaced as this is a major engine issue

The car will randomly lose acceleration and jerk forward. It will make a beeping noise while the hev system warning flashes on the dash. It also says to turn off engine. While the warning is flashing and engine light is on it goes into a limp mode and you have limited acceleration. It has almost caused multiple wrecks when I go to acceleration from turning or at lights in traffic because I cant go over 20-30 mph. I have turned the car on and off and the hev system and engine light turns off and the car continues to work normal. It eventually comes back on and does the same loss of power/hev warning. It will be random and does not matter on how fast you are going to trigger the warning lights and loss of power.

While on the highway vehicle started shaking violently, flashing engine light then service hybrid system along with every light on the dash! Car still running poorly, stiff steering very hard to slow down to get to safety! By the time I was able to pull over the engine was knocking and a burning smell was coming from the engine compartment. I popped the hood shut the car off , the exhaust manifold and converter(in one together) was so hot it was glowing! I’m thankful I was able to get to safety without it catching fire because it was on its way there! I called for a tow and sent it to the dealer where Hyundai is replacing the engine.

Hybrid system shut down while driving on I5 freeway at 60mph speed. Lost power completly finding myself in a very dangerous situation barely making it to the shoulder without being hit by other cars. This happened twice after 2 recalls performed on the car. Knock sensor replacement and software update. First recall was attempted by Hyundai of Kirkland WA. HEV system failure and multiple lights turned on while driving on the freeway the following day. Car was towed to Lee Johnson in Everett WA and I was told the recall was not performed correctly. After repair, same thing happened the following day. HEV failure and multiple lights turned on finding myself once again in very dangerous situation on the same busy freeway. Manufacturer is not taking this seriously. I see they have lots of vehicles with the same problem. Please investigate this failure before somebody dies. Next will file a police report. Car still at the dealership with no news on what might cause this. Has been at the dealer for over a week.
