general problems of the 2010 Kia Motor Optima

The car lurches or jerks when slowing down or stopping at about 20 mph . Lurch or jerking is enough to jerk to the driver . Has anyone got answer to why the kia Optima 2010 does this.

Car has very hard downshift at low speed going from 2nd gear to 1st. Seems to be alot of these complaints and would be nice to know of a fix for this problem!.

Vehicle jerks when downshifting at about 20 mph.

Takata recall - hard downshift from 2nd to 1st, usually around the 20mph mark! it's a sudden jerk as if it has been slammed into a a lower gear.

The car has a lurching issue when it slows down to 20mph when the car lurches with a hard down shift to 1st gear. This phenomena is especially acute when the car is cold or when you first start driving it.

While decelerating, either braking or coasting, the car will lurch violently when reaching approximately 22 mph. The severity of the lurch varies but in most instances it is hard enough to snap my neck forward.

Hard jerk when downshift into first gear at 20-22 mph. I am concerned that this could cause an accident on wet, icy or snow covered roads. When I asked the dealer about this problem, he said he had not heard of it.

When braking at lower speeds of less then 20mph the car lurches or jerks like the anti-lock brakes are engaging or the transmission is downshifting hard.

When braking or not around 20 miles an hour car jerks forward.

The car buckles when reducing your speed to around 20 mph. Also the rear seat door lock stopped working and my car is no longer under warranty and kia wants to charge me around 700 dollars to fix it.

The car lurches when down shifting from 18 to 20 miles an hour. Hard down shift at every stop.

When slowing down, either with or without braking assistance, car jerks as the transmission does a hard downshift from 2nd to 1st gear when reaching 20 mph. The force of the downshift is enough to jolt the driver.

When slowing down without the assistance of using the brakes, the car jerks as the transmission does a hard downshift causing enough jerk to the driver. This happens all the time.
