2008 Kia Rio Owner Comments

problem #1

Jan 182011

Rio 4-cyl

  • 51,400 miles


During acceleration between 50 and 70 mph the automatic transmission sticks to 3rd gear and the vehicle shudder or shakes real hard, the Kia dealer is saying "no problems found". this happens usually on the freeway when merging onto traffic, accelerating from 40 mph to the speed limit on the freeway and has caused several close calls. The vehicle is equipped with an electronically controlled automatic transaxle that is supposed to downshift during heavy acceleration then shift back to 4th gear however the vehicle stays in 3rd and the tachometer goes to the 6,000 RPM redline. The only way to fix the issue is to let off the gas and allow the transmission to fix it self which is extremely dangerous on the freeway.
