The hub bolts on the wheels may loosen, causing a wheel to detach from the vehicle after low-mileage use.
A wheel detaching from a moving vehicle can result in a loss of vehicle control, increasing the risk of a crash.
What to do
Owners are advised not to drive their vehicles until they are repaired. A remedy for the issue is currently under development.
Letters notifying owners of the safety risk were expected to be mailed in June, and a second letter will be sent once the remedy is available.
Owners may contact Toyota's customer service at (800) 331-4331 for more information.
