Jerking
1 - 13 of 13 Posts
If you have the non-hybrid, it could be the transmission hunting for the right gear. I test drove the 8 speed, and I found the automatic gear changing annoying. If there are different transmission modes, try "sport" it might hold the gears longer before changing. Also, try using the paddle shifters and shift up like you would do with a manual. If it is smoother, then it is probably the transmission trying to find the right gear.

You’re right, it’s a non-hybrid. I don’t have the paddle shifters, but I will try driving it in sport more to see if I notice what you’re saying. I normally keep it in smart mode. Thank you for responding!
I found in sport mode (on my short test drive) that it was hunting for gears all the time and really hanging on a down gear for fast acceleration. Like I honestly can't imagine driving in that mode normally. If smart is doing it, try normal mode?

I see what you did there...
Do you know if the dealer bothered to check the level of the transmission fluid? (shouldn't have to ask the question, but you never know). Also, the smart mode tries to learn your driving habits and adjusts the shifting modes accordingly. I think if there is more than one driver using the car it might be better to stay in normal mode, as jwslam said, where the shift points are fixed. I suggested the manual shifting because if it shifts smoothly manually, it would probably not be a defect in the transmission that is causing the jerking.

Not sure what you mean. Elaborate a bit?
Smart mode tracks your driving habits to see if you are an aggressive or conservative driver and balances the shift points between normal and sport to suit your driving style. If multiple drivers are using the car they might have different driving styles and smart mode may change the shift points. That's why I suggested choosing either normal or sport because they are programmed shift points and won't change from one driver to another. I suggested shifting manually because if manual shifts aren't smooth or result in "jerkiness" there might be a problem with the transmission. Low transmission fluid level could cause jerky or delayed shifts or even the sensation of shifting to neutral. There is a complete explanation on how smart mode works in the owner's manual.
Hi, just wanted to chime in. I had driven my car for over 6,400 miles now and yes, the first 500 miles it did the jerkiness/ hard up/down shift. With many visits to service and told that they can't replicate the issue in conjunction with Hyundai customer care case manager then been driven the car for 5,100 miles and one day it just stopped and decided to drive normal. Apparently from many research and many articles of an 8 speed automatic transmission that it is always going to be the case on where the transmission is going to hunt for that gear every shift especially during low speed. You and every new owner will have to dread the first 5,100 miles of the hard slamming, up shift/down shift. The hard up shift down shift is much worse in Smart mode than normal mode because of the low rpm.

Thanks for the info. What trim is yours? Does the jerkiness happen more often while you brake the car? I always thought it's more of a hybrid issue... Did you observe any error messages returned from your car?
No error message at all, my trim level is a non-hybrid SEL Convenience w/ premium package. From what I've been told from the service tech. the transmission is in a learning mode until it learns your driving habit. Yes, the jerkiness will occur during braking especially coming to a red light/stop sign. Also it always occur during going up a hill road as well as driving between 29-33 mph and slowing down between 5-3 mph.
As long as the car doesn't show any error message, not much anyone can do except ride it out, wait and see.
