Tried to open sunroof and it would not open. Seems to be a common issue on 20-22 tellurides. Please make this a recall so people don’t have to pay out of pocket for a repair, like the dealership is telling me.

Driving and trying to brake and brake pushed to floor and still not stop.I pulled over and called AAA.While waiting for AAA to arrive low brake fluid light came on.AAA driver arrived and stated bolts protecting driver side rear tire were gone and caliper on that side were left hanging.Towed to Kia Dealer and stated bolts were clearly removed.Last visit to Kia dealer was 30 days ago only for oil change not brake work.Dealer repaired caliper bolts and pistons for over 2000.Dealer had no idea why bolts came off by themselves and why it happened. There was no warning or lights going off until after brakes failed.Luckily when it happened i was only on back roads so could slow down eventually without incident but if I had been on highway not know how I would have come to a stop before crashing.Can anyone tell me why this happened and how to prevent it from ever happening to me or anyone else owning a Kia Telluride

I was driving at approximately 65-70 mph on the freeway at around 7:40 AM when the sunroof glass spontaneously exploded above me. The sound was terrifying...literally like an explosion or gunshot going off. Thankfully, I did not jerk the wheel at this high speed from the scare and the sunroof shade was closed, preventing glass shards from falling on top of me. The sunroof was not hit by any debris and was not near any large trucks, so it was a huge surprise when it happened.

Vehicle transmission has been slipping and Sutter since around 30k miles. Dealer has test vehicle and agrees but will not repair due to no codes in PCM or ECM. Vehicle stalled almost causing another vehicle to clip rear of vehicle. Issue is getting worst.

The sunroof button is defective. It allows both the “vent” and “slide open” functions to activate at the same time, which should not be mechanically possible. This causes the sunroof to jam and break the track system. It’s a design flaw that leads to physical damage and could easily become a safety issue if the sunroof fails while driving or during a storm. This needs to be addressed before more owners end up with broken hardware from a faulty control system.

Child Safety Lock Failure. At random times something within the rear doors will make a constant clicking noise for roughly 20 seconds. When clicking stops the dash will display child safety lock failure. The clicking noise sounds as though it is coming from an electrical component such as an actuator or solenoid.

I am reporting a serious and ongoing electrical and transmission issue with my 2021 Kia Telluride (VIN: [XXX] ). The problem began under 20,000 miles and has continued intermittently for years, progressively worsening. My vehicle is currently at ~99,600 miles and under extended warranty. The key safety concerns include: Transmission Lockout: The vehicle intermittently becomes stuck in Park and will not shift, even with the brake depressed. No-Start Condition: The vehicle will randomly become completely unresponsive—no dash lights, no infotainment, and no engine start. Electrical System Failure While Driving: Multiple safety systems fail mid-drive, including: Loss of power steering and air conditioning Random activation of ESC, TPMS, Collision Assist, Blind Spot, and Parking Brake warnings Infotainment screen turns off while in motion Component Failures Due to Electrical Shorts: Both the radio and the backup camera were diagnosed with shorts and had to be replaced under warranty. Brake Lockout Post-Shutdown: The brake pedal becomes very firm and the vehicle will not restart until hours later. Most concerning, my wife and children have been left stranded in the disabled vehicle on multiple occasions due to these issues. The car has been in the shop several times — around 50,000 and 80,000 miles — but no permanent resolution has been found. This is a clear and escalating safety hazard. The failures affect critical systems while driving and leave the vehicle unpredictably disabled. Kia has been made aware and an escalation is underway, but I am filing this report to ensure the NHTSA is aware of the pattern and potential danger these failures pose to others.
