Takata inflators? receive voluntary emission recall notice from Kia 1/16/18 took car in to be service for the recall 2/3/18 to Kia of East hartford, ct- drove car off the lot onto the highway. Loud sound and black smoke from rear end of the car, all lights came on and car stalled. Call service department immediately and was told to turn car on and off, that the computer had to reset. Car came back on but the airbag, low tire pressure and engine light remained on. Brought car back to Kia of East hartford several times was told nothing was wrong, instead that the sensor were off. Then eventually took the car to columbia Kia and was told the air bag clock spring was defective but not cover under warranty, the fuel canister was also cracked but not covered under warranty and the tps module was also damage (which was repaired by columbia Kia that actually took my claim serious). Made a complaint ticket with Kia manufacturer ref#12976894 but has gotten no where. In addition complaint was made 07/07/18 that when trying to make a stop and the ground surface is uneven the car would jerk and propel forward. Was told by the service department that that is how the anti-lock brake system work. Complained to Kia regarding the multiple times of near missed accidents due to mechanical braking system and car stalls. After purchasing the car with all of the warranty offered, was only able to get Kia to agree to fix the tps module. All of the other issues with the car was noted by Kia service department that they were defective, not wear and tear, but are not covered under warranty. Having problem with finding anyone that would even attempt to fix the airbag issue due to possible liability concerns and ongoing recall.

When the car accelerates from a stop, there is severe valve pinging sound. Kia motors America is aware of the issue, but are not taking any steps to address the issue "as it does not do anything to the car". the noise is very severe on the 2015 Forte and it is a defect in the design of the car. The wind noise and the valve ping make the car very loud. The dealer says that since Kia motors America is not addressing the issue, nothing can be done. Kia motors America has been aware of this issue for years but have failed to do anything about as they are do not care about their customers. Recommendations include upgrading to better gas, but the noise still persists. Kia recommends and advertises regular unleaded for the Forte, but a more expensive plus or premium grade is needed to decrease the sound of the ping. There is an additional added expense to the car that Kia fails to address.
