What's wrong, in plain English

The brake booster pump on these vehicles may fail. When it does, the Vehicle Stability Control system deactivates and the vehicle loses its power assist for braking. Because of this, these vehicles do not meet a federal safety standard covering electronic stability control systems.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your vehicle is included.
2. Contact a Toyota dealer for an inspection and, if needed, a brake booster pump replacement; call Toyota customer service at 1-888-270-9371.
3. The repair is free.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 19V544000.
