It's not hot or anything. Not sure what's going on with this car and dint want go spend hundreds of dollars just for someone to look at it.

I was driving down the street and my 2012 Hyundai Sonata 2.0T limited the instrument cluster illuminated and the power steering was no longer working. I immediately pulled over because the car started to slow down while pressing on the accelerator and before I stopped all the lights on the panel were out. I put the car in park and tried to cut it off with the push stop button and it would not cut off. Then I called road side assistance and before I ended the call the engine cut off without pressing the engine stop button. If I was on the highway or in a busy area the could have ended in a fatality. Why are there no recalls for this?

On June 22th, 2019 I was driving on the highway in my 2012 Hyundai Sonata gls and I heard a knocking sound under my hood and my engine light came on, so I pulled over to be safe. I called roadside assistance but the time of arrival was two plus hours. Since I was within a half mile of my home I continued on. Made an appointment with bentley Hyundai in huntsville, al for June 24th, 2019. My car sat for 2 days because it was the weekend and bentley Hyundai service was closed. The morning of June 24th, 2019 my vehicle would not start so I had it towed to bentley Hyundai. I ask chris erickson service advisor was there any service campaigns or recalls for my vehicle since I had many others for my Hyundai Sonata gls recently. After about thirty minutes he came back and said no which was not true. Here is the proof: Hyundai assurance car care website it states; service campaign T3G dealer best practice launch February 15th, 2019 for Sonata/sante fe sport/ tucson engine dtc P1326 wiring inspection/installation and engine replacement (tsb # 19-01-006H supercedes tsb # 18-01-032-2). It specifically states affected vehicles affected 2011-2014 my Sonata (yf) vehicles with 2.0L turbo and 2.4 engines that may experience the check light engine warning lamp illuminated with dtc P1326. According to bentley Hyundai service department it was a switch issues which caused the problem. I paid $572.36 for repairs. On 11/10/2019 I experienced the exact same issue knocking under the hood and engine light came on continous blinking. I was almost hit by an 18 wheeler because my vehicle decreased in speed drastically, pull to the shoulder drove very slow to advance auto two minutes away. They did a diagnostic code was P1326. I waited five hours for a tow from nashville, tn to bentley Hyundai in huntsville, al which cost me $475. Now Hyundai is asking me for $6785.82 for an entire new engine.

Car stop in the middle of the road when I tried to accelerate the was making a loud grinding noise. Prior to being on this road I was on the highway for about 35-40 miles before it stopped and wouldn't move. When I would put the car in reverse it would make a loud clicking noise. I called Hyundai they said that there was no open recall related to this issue

Under normal driving conditions, the car jolted and something didn't feel right on the right front side of the car. I was able to pull the car off of a 4 lane highway and into a parking lot. I discovered motor oil all over the inside of the engine bay and in the right wheel well. Upon inspection by two different mechanical shops and my insurance company, a hole was found in the engine. The vehicle has 90,017 miles on it. It has been indicated this is a manufacturing defect that would lead to engine failure and a hole in the engine. Hyundai is claiming that this is not covered under the theta II engine recall and have been extremely slow to assist. I am the second owner of this vehicle. I purchased the vehicle in June of 2017 with approximately 39,500 miles on it. I have changed oil with synthetic oil every 7500 miles which is the manufacturer's recommendation. There was no warning, no warning lights illuminated, etc. Prior to the engine failure.

- Greene, IA, USA

During normal driving on the highway (65 to 70 mph), the check engine light started flashing and the car lost power. I was very startled and I immediately exited and headed to my Hyundai dealership. The car had almost no power and was bucking hard. The engine had a loud knocking sound that grew in intensity as the engine speed increased. I drove gently to the dealership. This could have easily been a dangerous accident involving other vehicles as I was startled and lost power at the same time in moderate to heavy traffic and had to make a sudden exit from the roadway to avoid many more miles of travel to get to help.

My college age daughter was driving the car when it started knocking. Then a warning came up that said to park the car immediately, hybrid system failure. After having her car towed, it turns out the engine seized and needs to be replaced. It's a 2.4 liter engine very similar to the recall currently going on with the theta II engines.

- Siler City, NC, USA

I was driving down the highway going about 60 mph and all the sudden it's like the car shuts off, slowing to about 45. As I push on gas it does nothing then about 3 seconds later jerks back up and then repeats. It does this now everytime I am traveling. Besides giving me whiplash, it is dangerous because it could definitely cause a crash. My brake lights have been replaced 5 times in two years. Also there is always a loud clicking noise when driving. It sounds awful.

- Defuniak Springs, FL, USA

Was changing lanes and tried to pick up speed. At which point my engine locked up and no longer turn over. This caused my power steering to fail, brakes to be applied despite me not pressing them. Then my car began to smell like it was burning. I was going 50 on a highway when this accrued during rush hour.

My car does not accelerate properly. If the gas pedal is pressed after stopping it jerks very hard before going into gear. Also, my mileage for gas is broken. The electric meter will go up and down on its own and does not read properly. No matter if the car is in motion or stationary, the gas meter will jump up or down.

I was driving on a highway and my car simply stopped accelerating and began to shut off. How does a car just die in the middle of driving?! this is a serious safety hazard that needs to be addressed. I barely made it over to the side of the road to get out of the way of traffic. Nearly got hit by a car!! I was absolutely terrified that I was going to get hit because I was unable to move my car. Unknown reasoning for failure, but I believe this to be an engine malfunction or issue with the alternator. I am now aware of a recall on that indicates engine failure would result in vehicle stall, increasing the risk of crash!!!! unbelievable. Please address this problem so that no one else has to experience something as terrifying as this! recall number: 15V568000.
