| Description of the problem | I have an automatic transmission 2011 hyundai sonata gls, and the car seems to have trouble shifting gears. It does not happen all the time - maybe about once or twice a week, usually on my way to work or coming home from work. I reverse out of my driveway at home and reverse out of my parking spot at work. I turn my car on and shift my car into reverse, i hear a thump and a very slight lunge without ever taking my foot off of the brake. When i shift it to forward drive, it shifts as it should. Then, as i press on the gas pedal from 0-20 mph, the vehicle seems to lurch into the next gear. It lurches again when i speed up to 30-40 mph. As i travel on the interstate between 40-80 mph, i can feel the car lurch into a lower and higher gears as i let my foot off the gas pedal and accelerate. It is usually temporarily fixed by turning the engine off and then back on again. When i say "lurch", it feels like the car decreases speed for a split second and then resumes proper speed quickly. It's been going on for about three or four months, but since the weird gear shifting happens so rarely, i didn't think to look it up and do some internet research until now. It appears like a good amount of people are having this same problem. |
