NHTSA Complaint #11421524 — 2012 KIA OPTIMA

I was driving normal and started to hear a hissing noise in the front of vehicle. A vehicle cut in front of me I hit the brakes and another vehicle didn't slow fast enough and I went to hit the accelerator and had no power as usual and swerved to avoid the collision. I called dealership they said possibly my wastegate is out of normal voltage or need new turbo. I had a second opinion and they noticed the bolts and nut to service wastegate are rounded showing an attempt to maybe service or repair but unsuccessful. The turbo shows full function just inadequate boost.. The manufacturer has a bulletin and testing procedure Released on WASTEGATE test and adjusting procedure if needed as possible remedy. But I saw no recalls for my vehicle so reporting what I almost experienced and glad I have good driving experience to avoid an accident or life threatening situation behind the wheel of this vehicle now I don't feel safe until its proven resolved not just temporary fix.
