2010 Hyundai Sonata: jerking or lurching

Filed Aug 24, 2023 · Engine · NY

I purchased a 2010 Hyundai Sonata in February 2022 from the original owner. In July of this year, my engine failed due to the oil consumption defect found in many of Hyundai's engines produced at the Alabama factory. My oil and check engine light came on before it was time for my following oil change, despite making on-time synthetic oil changes during ownership. The vehicle hesitated and jerked on my commute to work, potentially causing harm to myself and other motorists. I went to take my vehicle to the mechanic on my lunch break. The car failed to turn over and has been inoperable ever since. I need my engine replaced at no charge. It's unconscionable that corporate would turn me away because the engine has 146k miles, which is nowhere near the industry standard 200k. Hyundai has inspected the vehicle and confirmed that an engine replacement is needed.

When the transmission is cold, while driving and slowing down to 20 mhp the card jerks, hard downshift from 3rd to 2nd, and RPM increase by several hundred rps. Once the transmission warms up, issue mostly goes away. Issue started this year. Second issue is the white paint easily comes off all over the car, even just from hosing the car with water. Issue has been going on for several years. Its happening all over the car payment. Dealership said they have not seen the issue before, however I see alot of owners with white color have this issue. Suspension seems to be very hard while going over any bumps. Feels like there are no suspensions mechanisms at all.

While driving the car died. I restarted and the check engine light and ESC light came on. The car jerked a bit and the check engine light went off but the ESC light off stayed on. After shutting off I started it the next day and the lights were off then after a while came back on. It is expensive to take to dealer to try something to see if it will fix the problem. Brakes jerky when applied.

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.
