After my car gets going and warms up, the engine has a problem. When it is time for the engine to shift to a higher gear, it makes a revving sound like the clutch has been pushed in and the gas pedal is being pushed. This mostly happens around 25 and 45mph. When you hit the as to make it stop it jerks and sometimes skids. If you take you foot off the gas it stops, but also slows down. When you hit the gas again it jerks again. If you try to speed up to get it to stop, it jerks again and this time pretty badly.

Car is overheating. Took it to a mechanic They replaced the thermostat but car is still overheating, jerking and so much more. The mechanic wants to charge more to fix it. I got a second opinion from another mechanic and after he reviewed the paperwork from the first mechanic. He searched my vin number and told me to contact this number because my vehicle is on a recall list. So I need someone to contact me about where and how we can get my vehicle fixed.

Hyundai Theta II engine has known defects with excessive engine oil consumption. Numerous consumers have complained of this issue as it appears widespread to the entire line of Theta II engines. A recent class action has limited the scope of the recall but an easy search can see it impacts (or has the potential to impact) nearly all Theta II (six gen) engines from Hyundai. The issue is that the scope of the recall needs to be widened to cover others who are impacted who currently have no recourse. Many are facing the same situation, which can easily be found with a brief search online. [XXX] At this time the issue is the car stalling at unknown times, fire from oil being displaced in other areas and various other issues due to improper and unusual oil consumption. The best situation would be to force Hyundai to review and expand the scope of their recall immediately. I found that I had excessive oil consumption which was causing my car to grind and shift heavily sometimes jerking on the highway. While I didn't crash, that possibility did exist when my car continually grinded heavy between shifting. I took my car to the dealer where they confirmed this issue. However, Hyundai declined to remediate. There are no warning lights and this could easily result in a crash, or fire. Hyundai has records of my maintenance, as my car is only serviced by the dealership where the car was purchased and I am the original owner.

I was driving my vehicle and a warning light indicating hybrid system charging failure warning. The vehicle had intermittent power problems and would not move appropriately in relation to the pushing the gas pedal. It would not go then would jerk forward. I was finally able to pull over to the side of the road safely. I turned my car off and when turned back on the error message failed. This happened on two other occasions. Later there was a whining noise when shifting into second gear. I took in for service and the hyundai dealership told me the transmission needed to be replaced. My safety and others were at risk due to loss of ability to drive the vehicle appropriately due to loss of power.

I was driving my car regularly one day and out of nowhere my car just shut off. When I started it back up I heard a knocking noise and it got louder as I went faster. So I pulled over and checked to see where the sound was coming from and it came from the engine. So when I started the car back up, on the way home the car was hesitating to move right and kept jerking. I also noticed the engine light and engine oil light came one so I went to go check it out. When I did the shop said the engine is blown and that there are recalls on my type of car. When I searched to see if there was I found out my car had none. But the exact same thing that happens to those cars happened to mine.

There is looseness/excessive play in the steering, causing a jerkiness motion side-to-side with minimal movement of the steering wheel. There is also a clunking noise when turning and when going over bumps in the road, sometimes the bumps cause the steering wheel to jerk to the side resulting in the car veering to the left or right. When this occurs traveling at a higher speed, I'm afraid it could result in either veering into the ditch or into oncoming traffic. I had my mechanic inspect the issue, thinking it was a suspension problem, but was informed it was a faulty "steering column flexible coupler" that is a known issue with this particular vehicle. This steering issue seems to be getting worse and worse by the day.

It jerks time to time we took it to a local hyundai dealership and they said they checked transmission and test came back fine. I have a 3 year old and the intermittent jerking scares us. It happens when it has difficulty shifting sometimes. Don't know when to expect it. It cut off one day in city streets then started back. On highway it doesn't have as many problems , but every now and then I have to manually shift on highway. It is a hybrid sonata 2011
