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

When I was driving down the road my car would just stop working in the middle of the highway. The engine would just stop. We nearly got on a accident because of it. I have no picture die to it sitting at the shop now for 3 weeks. My husband risks losing his job cause of the engine going out on our 2012 Hyundai Sonata. And it could possibly get repossessed. Then we couldnt drive it anymore. It wont crank or turn over at all. It would it up alot of oil just in one month and we had trouble with the windows wouldnt go down and the locks wouldnt lock. Had alot of electrical problems. Thats our only car to get to and from work, now we have nothing cause we cant afford to get it fixed. No one will help us with this recall on this viechle. We will lose our car if the recall on this car/engine and etc that is recalled on this viechle. Can you please help.

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.

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.

Metal in the oil and making a noise. It stalled not once but twice while driving on a highway. Had to pull over then put in park and restart. Just had oil changed and it was 1000 under needing it done again. Have no idea why metal shavings would be in the oil. Pretty sure something happened with the rods now.

- Weatherford, TX, USA

Vehicle stalls/dies while driving. It stalled 2 times but when I pulled over, it would start right away. While trying to make it home, it stalled for a third time and while pulling over it started smoking so bad I thought the vehicle was going to catch on fire. Vehicle had to be towed. There is an engine recall for this vehicle but dealer is giving me the runaround. Very disappointed with how Hyundai has handled the incident that almost caused an accident that could off been deadly.

When driving in huntsville, al on city streets and the highway when I'm turning my steering wheel it makes a clicking noise and the column appears loose. The brakes are sticking and requires me to push down hard to stop my vehicle. I have replaced the front lights and back ends lights numerous times and they continue to go out frequently. I purchased new tires in June 2019 from bentley Hyundai in huntsville, al and while driving the tire tube popped and deflated. There were no nails in the tire. There was a hole in the tube. I almost crashed.

Our 2012 Sonata is now on its 3rd engine (1 original and 2 add'L). These were subject to recall. Went for my routine oil change and my mechanic pointed out that there were metal shavings in old oil and on drain plug. Are we looking at another new engine to be installed. Bought it new as a commuter car because of the warranty, but it has spent more time in shop than me driving it.

My 2012 hybrid Sonata, 104,000 miles, suddenly started jerking and nearly stalling one recent morning on a drive from home on a divided road. It barely moved forward, badly jerking, message on the screen was : hybrid battery low. Pull up safely an place the car in park". so after 1/2 mile, I returned home. Because of low speed on a divided road, there was a serious concern of being hit by another car. I had the car towed next morning to the Hyundai dealer. They reported 'nothing wrong found' and returned the car which is running fine, though jerking transmission at low speed. I am wondering if this happened away from home, what shall I do. I need assurance that that will not happen again. How do we get that assurance ?

I'm not sure if this is an engine problem. When I would take off in my car, I accelerate and after I started going, I could push the pedal all the way to the floor and it had no power, it would almost completely stall in the road. I let off gas and push again and it would regain power and drive. No check engine light came on, no low oil, no service lights at all. All of the gauges in the dash red great and everything was normal. I started my car one day and it started making this chirping noise, almost like a bird chirping when I accelerate, but once I got up in speed the chirping stopped. I then started my car and there was a clicking, ticking type noise that got worse after 2 days. I took the car to a shop and was told it needed a new engine. Again, all gauges are completely normal, no check engine light at all to warn me there might be a problem with my car and now it cant be driven. I purchased this vehicle new. Why doesnt the check engine light or gauges work to warn of possible issues, this has to he a defect and what is the chirping, stalling, loss of power" if my engine was going bad, why did the system fail to alert me"
