2004 Kia Rio Owner Comments

My 2004 Kia Rio started to stall at stop signs and lights @ 24,000 I am also experiencing erratic tachometer readings (up and down) and I have had a continued rough idle. I have brought the car to my dealer on more than 6 occasions and at that point they only returned the computer chip and told me there seems to be nothing wrong with my car. After hiring a lawyer and constant pressure from them to fix the car, they ordered a throttle arm and agreed to try it out. On June 23, 2006 before they put the throttle item in, I stalled @ 30 mph making a turn onto to a street from a intersection. A car coming the other way and stopped inches short of hitting me on my drivers side door. At this point even with the new part placed in my car, I do not feel safe driving this car since they said there is no way to guarantee the problem will be fixed.

The contact stated vehicle jerked and cut out. When this happened the engine light came, on and there was a burning smell. The vehicle was taken to the dealership seven times, and they stated it was an electrical problem. They replaced the electrical throttle module every time, and stated there was a poor connection at the engine bulk. The problem has not been corrected at this time.
