Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I had buckled my seat belt and was grabbing my work phone, Iphone 13, to check it before leaving. I accidentally dropped it and it landed on the red part of my seat belt buckle. My seat belt automatically unbuckled. I was able to replicate this several more times. There is something going on with the engine where if you accelerate there is a coolant type smell then if you take your foot off the gas it sounds like the rpms are staying high. I've seen no warning lights for the car.”
NHTSA complaint #11627146, filed 2024-11“The car was leased on 12/18/2024. On 01/24/2025, after starting the vehicle, the check engine light came on with the description: a malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected. Contact your Toyota dealer to have your vehicle inspected. I am attempting to get an appointment now to get the car in for service but being a month old - this shouldn't be happening.”
