Model Years Affected: 1998, 2005, 2006, 2007, 2008, 2009, 2010

Exhaust & Emissions Affected: 2.7L V6

Average Mileage: 87,273 mi (27,000 mi - 181,700 mi)


Check Engine Light illumination—combined with a lack of power or a stumble on acceleration—may be caused by the throttle position switch (TPS). Kia released an improved part which should correct this concern.

    My 98 kia sportage hesitates while sitting or about to take off. When I give it acceleration it will proceed but at times stumbles when proceeding to go please help!

    Starts up but if I hit a bump it acts like its going to stall, then after a couple of miles my kia shuts off. If I jiggle the TPS pigtail it will start back up and then if I use the air you hear a lot of ticking sound then it stalls. You hear the clicking sound coming from the TPS.

    My 2006 Kia Sportage started stalling when I would come to a stop light/sign. It would start right back up but I was afraid that it might not. I took to the Kia dealer to troubleshoot. Of course it didn't happen for them. It continued to happen so I took it back and told them to figure it out. 2 days later, they replaced the throttle position switch and the problem seems to be fixed (4 days now without the problem). Cost for part was minimal - $41.00 but labor was $160. Total bill was $213.00 but I'm glad to pay it if the problem is fixed. My car only has 31,100 miles on it and otherwise, its been a great car.

    Hard downshift when brake is applied. Changed TPS and had dealer clear the codes and it runs fine again with no issues.

    Hit 30K miles exactly today. Noticed that the gas pedal was "sticking" slightly. Would step on the gas from a stopped position and have to press harder to accelerate and then the car jerks forward.
