There are 6 owner-reported driver assist & adas complaints for the 2021 Kia Telluridein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
This vehicle was purchased back in July 2023. On multiple occasions since then, the Automatic Emergency Braking system has activated and slammed on the brakes when not needed. There have been no other cars, animals or other hazards to cause it to do so. Very dangerous that this keeps happening. Most recent and worse incident was yesterday(5/16/24). It is going to the dealer for service today. It's still under warranty and has approximately 55000 miles on it. Kia customer service help line showed little concern over incidents. We'll see what happens at the dealership today when I take it in.
The front bumper sensor has stopped working. This is preventing proper function of the forward collision warning and the parking collision warning. I took this to be fixed to Executive Kia of Wallinford, CT and they identified corrosion of the component as the cause of the failure. My car has had no accidents or damage to bumper so any corrosion is due to improper sealing of part, or weather proofing of bumper. An online search identified many other Kia owners dealing with this same issue. My extended warranty through Fidelity Inc sent out an inspector to review this and they are refusing to cover the cost of the fix since it is due to "corrosion." Including photos my Kia dealer mechanic sent me of the corrosion.

The contact owns a 2021 Kia Telluride. The contact stated that while engaging the Forward Collision Avoidance system per the manufacturer’s instructions, the Forward Collision Avoidance system failed to engage. The contact stated that the Forward Collision Avoidance system was inoperable. The contact stated that while driving and approaching another vehicle, the Forward Collision Avoidance failed to engage. There was no warning light illuminated. The vehicle was taken to the dealer several times. The dealer test-drove the vehicle and informed the contact that the Forward Collision Avoidance system was operable when the Adaptive Cruise Control (ACC) mode was activated. The dealer diagnosed that no issues were found. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 9,300.
Had a new transmission installed in February 2022. Now, beginning March 13, warning lights come on to check blind spot and forward collision systems. About 10 seconds after the car lurches violently. This has happened at full speed on interstate which is a huge risk for injury/death. I have video of this phenomenon.
The Blind Spot Warning light doesn't work all the time. I have read through the Kia owners manual and couldn't find an explanation for the malfunction. I have tested in local and highway driving both low and high speed during good days and nights. Warning only comes up sometimes, then stops and comes back only after vehicle restart, then repeats the issue.
