The car drives normally until you press on the brakes after going high speeds it jerks. At stops if the car isn't in neutral the engine stutters we've replaced the cam shaft sensor 3 times now and that's the code that comes up everytime the check engine light comes on after the jerking. We also replaced the spark plugs and coils hoping it would help the shaking at stops and it didn't.

I bought the used car in the spring, it currently has 44,000 miles on it. When the weather got cold, it began to jerk violently at 20 MPH when I decelerate. When I slow the vehicle it feels as if someone has hit me from behind. When making right hand turns I am concerned that the car will switch gears and lurch me into oncoming traffic. Items on my seat that are not secure are propelled to the floor. I will not let anyone else operate the vehicle because I feel that it would be very easy to lose control of the vehicle during the deceleration. I contacted hyundai corporation- mistakenly told me it was under warranty and then recanted when they realized I was a second owner which only covers 5 years or 60,000. Hyundai representative states that this is not a safety issue, that there are no technical bulletins applying to my automobile. Refuses to fix it free of charge despite there being countless other complaints of the same nature on the federal safety agency site.

While driving down the street, the car started slowing down with jerking and shaking like motions which was very distracting and caused me to become afraid in the moving traffic. It was obvious that something was going wrong. Then I glanced at temperature gauge and noticed it was heating up in the red and ran hot. Now it won't run.

The ESC light comes on intermittently while driving. The car jerks as this happens. Once in this condition, the car runs extremely rough and will even stall when starting from a full stop (stalls in the middle of an intersection). During one occurrence, the car wouldn't go faster than 25 MPH when going up a slight incline. I can't turn off ESC; pressing the switch is ignored. If I turn off/on the car, the problem seems to go away for a while.

The ESC off light comes on and pushing the on/off switch does not put it out. If I shut the car off and re start, the dash light goes out. It seems like this usually happens going 30-40mph and I feel a slight jerk in the car then it comes on. It has also happened while driving on the highway around 60mph. The last time this happened was 07/12/17 driving around 30mph.

While driving the car at a rate of 30 to 40 MPH, I felt a jerk in the engine or transmission speed of my vehicle, and afterwords noticed my ESC off light and engine lights had been illuminated and unable to be shut off with my ESC switch. I also noticed that I was unable to rev my engine past 3000rpm's, consequently affecting my vehicle's usable power band and rendering me(the driver) unable to control the car's overall speed. After turning my vehicle off and then back on, the problem would go away, but only temporarily until I was again driving. I then went to a mechanic to have my car's computer scanned and found that there was a problem with my crankshaft or crankshaft sensor. My computer was then reset, but the problems persisted again shortly after.

When driving my car will jerk like it is shifting rough. At first I thought it was the brakes grabbing but when I googled it I read that it could be ECM and TCM software problem. It jerks sometimes so badly that it feels like I have bumped into something. Called dealer but was told there is no recall for this problem. Was also informed that it is probably an update needed to the ECM and TCM software and it could cost $200. If that is the case it should be something that hyundai covers.
