2017-2019 Nissan Rogue Hybrid Loss Of Brake Assist

On 2022-08-16 09:03:24

Nissan will be contacting the owners of certain 2017-2019 Nissan Rogue Hybrid vehicles because of a problem affecting brakes. These vehicle fail to comply to the requirements of the Federal Motor Vehicle Safety Standards for light vehicle brake systems.


In May 2022, Nissan opened an investigation after receiving reports of loss of hydraulic brake assist in certain Nissan Rogue vehicles in Japan. Nissan expanded this investigation to include vehicles outside of the Japanese market and analyzed the conditions that could increase the chance of the problem occurring. Because a non-compliance could not be ruled out, Nissan decided to conduct a safety recall campaign in the U.S. market to fix the affected vehicles.


According to the description of the noncompliance, certain driving conditions such as repeated braking combined with high ambient temperatures in the engine compartment can cause the brush temperature inside the motor pump housing to increase. If the temperature exceeds an acceptable range, a lack of lubrication can cause sparking from brush and commutator chatter that can result in abnormal commutator wear. This abnormal wear may lead to brush vibration, causing the pigtail to bend repeatedly and disconnect. The problem will eventually lead to a decrease in brake assist output.


If brake assist output drops below an acceptable level, the red brake system warning indicator will illuminate and the driver will receive an audible warning buzzer. If the vehicle continues to be operated in this condition, the driver may begin to experience a change in brake pedal travel and feel; an increased pedal effort, and increased stopping distances. Although the vehicle braking system will continue to function, the brake assist output may not meet certain performance requirements specified in S7.5 and S7.6 of FMVSS 135; Light vehicle brake systems.


A repair for this non-compliance is still under development. Nissan will mail interim notification letters to all owners of affected vehicles, beginning September 22, 2022. When the final fix is available, Nissan will mail notification letters to owners with affected vehicles. Nissan's number for this recall is R22A6 and the NHTSA campaign number is 22V-549.
