NHTSA complaint #11372396, filed 2020-10, 2,800 miles

“Driver's side window remained stuck open about 1 inch when driver rolled down window with slight tap on window switch driving motion at highway speeds. Window would not go up or down while in motion when using switch to open or close window even after coming to complete stop (on shoulder of road) and shutting down vehicle. Was able to fix when putting vehicle in accessory mode (not running or in motion) and place hands gently on both sides of window to gently move up to highest allowed position then close window with switch. This fixed the problem and window switch operated as usual. …”

“My main screen on my 2021 Telluride goes out suddenly, turning off the backup camera and collision warnings. Sometimes when I start the car it never turns on, sometimes it starts to boot and then goes out and sometimes it works for a few seconds/minutes and then turns off. Once and a while it turns on and stays on for days before going on randomly again.”

“I have 2 issues going on with my vehicle. The trim on the outside of my doors is coming off which I know was a recall for some telluride vehicles about this old. Also ive been having some electrical issues/hot smell like something is burning if the heated seats get turned on.”

NHTSA complaint #11729468, filed 2026-04

“Bought car on a Saturday (6-20-26)and that night noticed the drive mode was broke and the forward Collison is broke and will go on and off. Dealership said they did the whole inspection on the car before they put it on the lot to sell. Also, oil was extremely low when I left the lot and had to go back for an oil change. Took it to them on 6-22 to repair and have had to call to ask about my cars status when they said they would call me. Never would get an answer as to what was going on.”
