2020 Kia Telluride: adaptive cruise control problems

Filed Mar 7, 2024 · Brakes · VT

There have been several times over the last couple of months when my car brakes on its own. I have not had any "extra" features on such as cruise control or lane assist. I have been driving 70 mph on the highway, my car suddenly brakes, and then I am unable to accelerate. It is absolutely terrifying. We called our nearest Kia dealership after the second time and they told us to get a car wash and since it hasn't been consistently happening, they wouldn't be able to re-create it or fix it. We have been going out of our way to keep the front sensor, and it still happens. I worry that I will be driving on the highway (again) when this happens, and the semi truck behind me won't have time to adjust to my sudden, and unwanted, deceleration.

Had my seven year old Granddaughter in my vehicle and was momentarily distracted and the traffic in front of me stopped for geese crossing. I was in cruise control and my forward collision warning system failed to work! No accident as I took the ditch. KIA America Inc. had a voluntary recall for this problem and I took it in to my dealer and they reprogrammed the system. Did not work so I called KIA to see when there would be a recall? They told me to take my vehicle to a different dealer? As this is a safety issue I am concerned and even though they acknowledged it is a problem they seem to not want to do anything!

While operating the vehicle and braking, the dashboard warnings lights began flashing. The brake pedal went to the floor and did not brake the vehicle. No amount of pumping of the brakes helped. At about 3-5 MPH I struck the stopped vehicle in front of me at an intersection. Later that day the same thing happened, and this time I pulled the emergency brake lever and held it. The warning alarm sounded but the brakes never slowed or stopped the vehicle. I drove the vehicle safely to a repair shop and it was then towed to a Kia dealership. Where it is available for inspection. The error codes on the ECM indicate that the right rear ABS Speed Sensor has lost communication. I do not know if the component has been inspected by KIA. When the failure occurs the BCW light goes on, the ABS light goes on, the Master warning light goes on, the Electronic Stability Light goes on, and the AUTO HOLD lights amber. The dealership has reviewed the codes on the ECM which follows: ABS/ESC(+EPB) 2 Codes 1.C121102: Wheel Speed Sensor Rear-RH Invalid/no Signal 2.C121002: Wheel Speed Sensor Rear-RH Range / Performance / Intermittent Integrated Body Control Unit- BCM 1 Code 1.B121200: Front Center Right Sensor Fault Integrated Body Control Unit- SMK 1 Code 1.B121200: Front Center Right Sensor Fault Integrated Body Control Unit- TPMS 1 Code 1.B121200: Front Center Right Sensor Fault PSM (Power Seat Module) 1 Code 1.B163700: System Not Initialized BCW (Blind-Spot Collision Warning) 2 Codes 1.C169381: ESC Signal Error 2.C167581: Signal WHEEL FL or WHEEL FR or WHEEL RL or WHEEL RR not Valid MFC (Multi Function Camera) 1 Code 1.C186286: Invalid Signal of SCC SCC (Smart Cruise Control) 3 Codes 1.C121181: Wheel Speed Sensor Rear-RH Invalid/no Signal 2.C136081: ESP Irreversible Error 3.C174181: ESC-not available VSM (Check ESC) 4WD Control 1 Code 1.P183000: Clutch Torque Tolerance Lower Limit.

Dash gage cluster (tach, speedometer, fuel, and engine temp) all go to zero while driving. The digital speedometer readout is also zero. Basically the entire dash is dead minus the entertainment system which functions perfectly.This also shuts down all adaptive cruise and collision avoidance systems. Restarting the vehical will not bring dash instruments back. Ocassionally cycling to door locks and or disconnecting negative battery lead will bring dash instruments or they will begin randomly begin functioning again on their own. They always malfunction and come back as an entire cluster. I also have video of the vehical in motion with the instruments dead.

After driving about 10 or 15 minutes both the adaptive cruise control and the forward collision warning system stop operating. Even after you clean off the sensor it does not help. It randomly clears itself, but will also stop again after some time. This happens both on local roads and the highway.

Inside temp was set at 72 degrees with the fan setting on the third setting. I am unsure of the outside temperature but it was above freezing. My local kia dealer, roper kia of joplin, mo inspected the vehicle thursday morning at 8am, after their inspection they contacted the district service manager who authorized the sunroof to be replaced under goodwill warranty at no cost to myself.

The kia has a system that controls cruise control in a special way. This system allows you to place the car it this mode and what it does beyond cruise control lane change control. It detects the highway speed limit signs example: I drive from prescott az to phoenix periodically. The speed limit on I -17 is 75 MPH for most the trip heading south on i17 it is 75 MPH at sunset point the speed changes from 75 MPH to 65 MPH. The car changes speed to 65 MPH. It changes back to 75 MPH later exciting times passing through rock springs. I am doing at 75 MPH ( no one is in front of me they are in back and one to the left side. ). The car speed drops to 45 MPH. The freeway speed is 75 MPH. However, the side road in rock springs is 45 MPH. So now I have 4 cars trying to avoid me because I suddenly going 45 MPH in a 75 MPH zone. Approaching anthem - the car suddenly drops to 35 MPH in a 75 MPH zone. No one was in front of me. But the speed limit on the side road next to the freeway is 35 MPH. No one in front of me. I have cars around me honking and avoiding me - because I am driving 35 MPH in a 75 MPH freeway speed zone. This is dangerous. The dealer just says it is an option.
