Vehicle was taken to Clovis Kia to address recall NHTSA# 23V218 (SC267). Kia was unable to fix the issue and ordered a battery pack replacement (they replaced the current battery pack 2 years and roughly 20K miles previously). New battery pack was installed and the system still does not function properly.

2 years ago Kia had a recall on the catalytic converter that I found out about after my car displayed the engine light and shut down and would not drive. I had to tow it and they told me it was the catalytic converter but it had a recall.

This is regarding high exhaust gas temperatures that may damage the catalytic converter and potentially other parts, dealers are supposed to upgrade software on all kia souls even if not recalled. The kia dealership in warrenton oregon says my car doesn't need it, I strongly disagree and wanrythis software updated asap!

When accelerating from a complete stop the vehicle will not accelerate. Pressing the accelerator a little or a lot does not matter. The engine does not produce RPM and does not accelerate for around 3-5 seconds.

My car, which is under 5000 miles, had one of its fuel lines decay or chewed by an animal. The location of the damage was on top of the engine. Before I discovered the defective fuel line, my car had been running just fine, with no warning indicators in the dashboard.

I experience intermittent hesitation when pressing on the accelerator. It feels like the car isn't downshifting correctly or isn't getting enough fuel in order to pick up speed. I took the car to the kia dealer service department and they said they didn't find any problems and couldn't duplicate the issue.

Recently, I have been experiencing problems with my pumping gas into my car. Every time I attempt to put gas in, it overflows as if it is full, but it's not. The gas cap no longer clicks when attempting to close.

Gas mileage stated is nowhere even close to what's stated on either city or highway. I would guess 10-15% off
