“Two issues happening at the same time. “Key not detected” and “TPMS System Malfunction”. Key not detected: Happens at various times, either at startup or while driving, an error message that says “Key not detected “ comes on the dash and a loud beeping. My concern is that I may become stranded somewhere if the system cannot detect the key when trying to start the truck. The issue has been confirmed by both the dealer and Toyota and has not been fixed to date. …”
NHTSA complaint #11768897, filed 2026-10“My 2025 Toyota Tundra’s air conditioning is not cooling properly. The A/C does not perform as expected, especially in hot weather. I am concerned this may be a defect in the HVAC/climate control system. I am also concerned about driver safety because poor A/C performance in extreme heat can affect the driver and passengers, and HVAC issues may also affect proper window defogging/defrosting. I am requesting that NHTSA review this issue and track similar complaints for possible investigation. …”
NHTSA complaint #11738101, filed 2026-05“There’s a delay in throttle response. Especially when making a turn across traffic. Throttle would not respond for at least 1 to 2 seconds. Even at full throttle the truck did not respond while cars were coming towards me. This has happened to several tundra owners. Check Facebook tundra group and you’ll find others with same issue.”

This had happened multiple times before scheduling service appointments. …”
NHTSA complaint #11703962, filed 2025-12“Radar system and traction control shuts off during normal operation and requires vehicle to be pulled over and turned off then back on to regain control.
