Owner report 11654872 · 2025-04-15 (April 15, 2025)
As I was driving down a suburban road at about 30mph the brakes suddenly came on by themselves for few seconds as I approached a parked car on my right side. As I started to pass this car my vehicle continued moving forewarned and I did not come to a complete stop. There were no cars in front or behind me except for the one car parked to my right. There were two electric beeps when the car braked.

Owner report 11638192 · 2025-01-24 (January 24, 2025)
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.
