Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“A few weeks after purchasing this vehicle in Dallas, TX we drove to Florida. About 4 hours into the trip we stopped for lunch and noticed both of our cells phones had not charged and in fact had discharged quite a bit. Further testing shows none of the front or rear USB Type-C ports would charge any cell phone we plugged into them. I purchased a USB volt meter and verified that the car would only send a small fraction of an amp to any cell phone plugged into these four ports. …”

NHTSA complaint #11703053, filed 2025-12

“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.”
