Hyundai Sonata owners have reported 5 problems related to transmission solenoid (under the power train category).
When vehicle is cold and I decelerate down thru 20 mph, the transmission down shifts abruptly causing a jerking motion. I have been told by an auto mechanic who researched it that there was an actual recall by Hyundai for this issue. He said the problem was that Hyundai installed computer control equipment from an older model in their 2010 Sonatas and this resulted in a failure in proper communication between the computer and the automatic transmission's solenoid, causing the abrupt down shifting at 20 mph when car is cold. One last note: when this first started occurring, it would cause the "fix engine" light to come on, but this has not happened for about the last three weeks. The abrupt down shifting when cold still occurs consistently, always right around 20 mph.

Hyundai Sonata se 2011, 630 miles. While traveling on an open stretch of highway at a steady speed of 70mph, there was a sudden loud â€œthumpâ€� sound. The entire vehicle jerked violently with sudden deceleration as if it hit a solid object. Driver did not see any obstruction or imperfections on the road prior to the noise. Driver realized that the speed was almost instantly reduced from 70mph to ~63mph. Rpms were racing unusually high, around 3000 when typical operating range is 2000. Driver shifted from automatic â€œdriveâ€� gear to shiftronic and realized that the transmission was stuck in 4. Neither the manual or automatic transmission could change the gear. Driver immediately took vehicle to dealer. Dealerâ€™s service department acknowledged that the transmission was stuck in gear 4, but technician was able to reset the transmission by turning off the engine and restarting. Based on the computerized error codes, dealer replaced the body valve harness and solenoid.
While driving the vehicle at 50 mph, it suddenly slams into third gear causing a violent jerking and sudden deceleration. The engine light comes on and the car remains in 3rd gear for a period of time and then returns to normal. This occurred two days in a row. The second time I was almost rear ended when my vehicle slammed into third gear. It was determined that the transmission wiring harness and overdrive solenoid were defective. Error code was p0765.
