2023 Kia Telluride

Kia installed voluntary safety recall on my car - SC357 ECM SW UPGRADE (VESC). I drive up and down steep mountain roads. Previous to this installation when I downshifted the transmission it would slow down the car. After the installation, going down two or more gears, the car now speeds up instead of slowing down. It shows on the gas mileage indicator that the mileage is going down instead of up. It would be expected that the gas mileage would increase instead of decrease. The accelerator is not being used when this occurs. It would appear that the car's computer system is causing fuel to be added to the engine to accelerate the car at lower speeds. This is especially dangerous going downhill when a downshift is expected to slow the car. It causes increase use of brakes which can cause the brakes to overheat. I have been able to avoid overheating the brakes but this is not a safe situation. Supporting the theory that the car is using fuel to accelerate in lower gears is the fact that my gas mileage has decreased about 1.5 to 2 miles per gallon on a tank full of gas.

My 2023 Kia Telluride started leaking water to the inside of the vehicle headliner and running out the 2nd row reading lights and all the way tobthe back hatch when it rained. This could cause significant electrical shortage in the lights, airbags and rear hatch or any other component the water makes contact with. It will most likely now cause mold in or on the headliner. When the vehicle was recently at the dealer for yet another set of recalls along with an extended warranty repair of the electronic thermostat, the service rep noticed water coming out of the headliner area on the driver side when driving it around to the shop. The service tech then pulled down part of the head liner on the opposite passenger side and borescoped the sunroof/panaramic drain tube on the passenger side and found that a hole was "chaffed" in the drain tube. They did not borehole any others at this time but with the service rep saying she saw water on the driver side it is believed that the drain tube on that side also has a hole. This is a manufacturer defect.

Within the last two weeks the vehicle has died approximately 8-10 times. Dealership checked the battery and found it to be in good condition. Approximately two weeks ago I walked outside and the cooling fan was on after the vehicle was parked for more than four hours. To this day the dealership can’t figure out why the cars battery is constantly dying. I believe the cars cooling fan turns on by itself and drains the battery. I am also concerned the fan turning on randomly on its own will create a fire risk due to it running for an extended period of time while the vehicle is turned off. I have video to support my claim of the fan turning on by itself.

My car just started making a knocking sound when I turn. Brought it in for diagnoses and was told it's the AWD Coupler, WHICH is a part of the powertrain component, but it's not covered under my 100,000 powertrain warranty, and is only covered up to 60,000 miles. This is a known issue according to Facebook, blogs, and reddit and many Kia users have had the same problem on their cars. It should be a recall and fixed if it's happening so frequently.

There was a low-speed collision with a deer (approximately 10-15 mph). The vehicle continued to run fine after the collision and we were able to drive it home. After the next start, the engine was shaking all over and started smoking from behind the engine. The battery was disconnected but it continued to smoke. After further inspection, we were able to find a fire and extinguished it using a fire extinguisher. We had issues with this car prior to the collision where the engine would misfire after the car would get wet, but would only produce temporary codes. This was checked out by the dealer and we were told there's nothing that they can do. A few weeks prior to the collision it happened again and the check engine light went to a confirmed/permanent code and it was related to cylinder misfires. If we would not have had a fire extinguisher or had been able to roll it away from the house, the occupants, vehicle, and house would have been in danger of the fire. The source of the ignition has been confirmed to be the ignition coils, but the root cause of this has not been determined and it has just been assumed that it is related to the collision, without an actual root cause identification.

The vehicle electrical system could be a fire hazard since the vehicle electrical system is incurring parasitic draw down of the battery. Believe there is a class action lawsuit filed relating to the problem. It is well known issue wit KIA Corp while the dealerships play dumb. Thank you.

I was involved in a rear end collision, with the SUV behind me going 65mph and my vehicle only at approx. 20mph. I was then pushed into the car, which I struck in front of me. My airbags did not deploy and though I was wearing my seat belt I was still propelled upward cutting my eye on the visor and bruising on my chin and lower lip from the steering wheel. I am concerned as to why the air bags did not deploy or the seatbelt lock. The damage was significant and my vehicle including the one that rear ended me are both totaled. Can this be looked into?
