2019-2020 Toyota Corolla Hybrid, Rav4 Hybrid, Prius and Prius Prime Potential Loss of Power Brake Assist

On July 24 2019, Toyota filed a Noncompliance Information Report (NCIR) with the National Highway Traffic Safety Administration (NHTSA) informing the agency of our intent to conduct a voluntary Safety (Noncompliance) Recall on certain 2020 model year Corolla Hybrid, certain 2019 model year Rav4 Hybrid, certain 2019 – 2020 model year Prius Prime and certain 2019 model year Prius vehicles.

Condition:
In the subject vehicles, there is a possibility the brake booster pump may have been manufactured improperly, and in some cases, it may stop operating. If the brake booster pump stops operating, multiple warning lights and messages will illuminate, and/or audible chimes will sound. In this condition, braking assist could be lost completely after several brake pedal applications, resulting in increased stopping distance. In addition, the Vehicle Stability Control will become deactivated, and other vehicle features could be affected. Deactivating the Vehicle Stability Control system may cause the subject vehicles to not meet the certain requirements of FMVSS No. 126. A deactivated Vehicle Stability Control or a sudden and complete loss of braking assist while driving could increase the risk of a crash.

Remedy:
Based on the vehicle identification number or an inspection, the dealer will replace the brake booster pump with a new one, if necessary, FREE OF CHARGE.

Covered Vehicles:
There are approximately 6,500 vehicles covered by this Safety (Noncompliance) Recall. Approximately 8 vehicles involved in this Safety (Noncompliance) Recall were distributed to Puerto Rico.

Owner Letter Mailing Date:
Toyota will begin to notify owners in mid-September 2019.

What is the Brake Booster Pump?
A brake booster pump is a component of the brake system which provides power and controls fluid pressure.

Are there any warnings that this condition exists?
No. However, if the condition occurs, multiple warning lights and messages will illuminate, and audible chimes will sound prior to losing power brake assist.

If the condition occurs, will the brakes remain operational?
If the condition has occurred, the brakes will remain operational. However, the condition may result in loss of the power braking assist feature and, therefore, more force may need to be applied to the brake pedal to stop the vehicle.

What is Toyota going to do?
Based on the vehicle identification number or an inspection, any authorized Toyota dealer will replace the brake booster pump with a new one, if necessary, FREE OF CHARGE.

How long will the repair take?
The inspection will take approximately one hour. If the brake booster pump needs to be replaced, it will take approximately five additional hours. For vehicles that do not require an inspection, brake booster pump replacement will take approximately six hours. However, depending upon the dealer’s work schedule, it may be necessary to make the vehicle available for a longer period of time.
