FORWARD COLLISION AVOIDANCE: WARNINGS

And caused a server accident that left me with serious injuries. And I cause of the defect they found me at fault said I failed to yield at a stop sign. The car never was fixed from the 2 times the motor has to be replaced by Galena Kia in fort Myers fl. They even caused the ac to go power retarded and wouldn't work half the time.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
My complaint is regarding the rear windshield, which came with the vehicle when I purchased it new in 2016 from a Kia dealership (Santa Fe Kia, Santa Fe, New Mexico). The Optima has never been in an accident. Over the last several years, the rear windshield has become increasingly blurry making it difficult to see traffic behind me. This situation is worse particularly at night. The blurriness is both from the outside looking in and inside looking out. I have called several Kia dealers and they claim that they are not aware of the problem, and have told me that the windshield is not warranted.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I purchased a brand new 2016 Kia Optima and have been experiencing a really bad rattling noise that is coming from the motor. I have taken my car back and forth from the Kia dealership and each time they inspect my car, they tell me that they can’t hear any rattling. As a mentioned earlier, the rattling noise is still there. I have been to the Kia in Durham, North Carolina and the Cary, North Carolina Kia dealership and still nothing has been done. I believe that my head gaskets or something like that in the more was defects when I purchased my vehicle. I also feel that the Kia dealership knew that my car had a defective motor and failed to inform me of that information. I would be glad to have my vehicle available for inspection upon request. How my safety and the safety of others are put at risk, is because the car could suddenly catch fire, it may stall in traffic, etc. The problem has not been reproduced or confirmed by a dealer or independent service center but I do know that something is wrong with my car and has been since I purchased it brand new in 2016. Kia Motors did a quick look at my car and stated that they heard not rattling noises coming from the car. Other than that no other component been inspected by the manufacturer, police, insurance representatives or others? There are no warning lamps, messages or other symptoms of the problem prior to the problem and it occurred over 2 months after I purchased the Kia Optima. If you are uncertain, simply state UNKNOWN, I am not sure as to why the vehicle rattles when taking off, but it is and have been loud enough for me to notice and my passengers as well. Therefore, I hope that this is something that you would look into and get some type of remediation. Thank You,

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Suddenly, the warning lights on my dashboard resembled that of a christmas tree. I was seeing warning lights for the passenger airbag, blind spot warning/assist, auto-hold, adaptive cruise control, automatic emergency braking, lane departure warning, etc - were all suddenly offline. After finally getting an appointment scheduled with my local dealership, I was told that the airbag module had gone bad and needed replaced. With that module out, the car could not communicate with the other systems and thus was the cause of the errors/warning lights.

Air bag light came on after I also began having issues with blind spot detection warning lights. ABS lights on as well. Took vehicle to Kia Dealer in Gainesville GA and they told me it was the left rear wheel sensor. Wanted $800 to repair ( no longer under warranty). Took vehicle to my mechanic, who ordered the part and replaced sensor. ABS lights & BSD lights went off for almost 2 weeks, then came back on. Air bag light has not gone off.
