Mazda will be contacting owners of certain 2019-2020 Mazda 3 cars because of a programming error affecting the forward collision avoidance system.
According to the defect report, incorrect programming of the smart braking system (SBS) control software may cause the vehicle to falsely detect an obstacle and apply the brakes to avoid a collision. If the SBS is unexpectedly activated while driving, the risk of a rear end collision from the following vehicle is possible. Drivers will be warned when the defect is occurring through an audible alarm and a warning message displayed on the dash board.
Dealers will correct the problem by updating the SBS software. Vehicles with certain production dates will receive an instrument cluster software update or replacement and a replacement owner’s manual. The recall is expected to begin February 17, 2020. Mazda’s number for this recall is 4219L and the NHTSA campaign number is 19V-907.
Nissan will be asking the owners of certain 2015-2019 Infiniti and Nissan vehicles, equipped with ADVICS ABS actuators, to return to their dealerships for a problem affecting the braking system. These vehicles were previously recalled under NHTSA campaign number 18V-601, but were not repaired. This new recall (19V-807) also expands the previous population. The affected models include:
- 2017-2019 Infiniti QX60
- 2016-2018 Nissan Maxima
- 2015-2018 Nissan Murano
- 2017-2019 Nissan Pathfinder
Due to manufacturing variation, the ABS actuators may contain an oil seal with inadequate sealing performance. The seal could prematurely wear and leak brake fluid. If this occurs, the ABS warning lamp will illuminate to warn the driver, but if the warning is ignored, the brake fluid leak could create an electrical short in the actuator circuit. In rare instances, this could lead to a fire.
Note: When brake fluid leaks onto the circuit board, the ABS warning lamp will remain illuminated for more than 10 seconds after engine is started. If this occurs, owners should park their vehicle outdoors away from other vehicles or structures and to not drive the vehicle.
Toyota will be contacting the owners of certain 2019-2010 Toyota and Lexus vehicles regarding a problem affecting the braking and stability control systems. The vehicles involved include:
- 2019 Lexus ES300H
- 2019 Lexus LC500
- 2019 Lexus LS500
- 2019 Lexus LS500 H
- 2019 Lexus U250 Hybrid
- 2020 Toyota Corolla Hybrid
- 2019 Toyota Prius
- 2019-2020 Toyota Prius Prime
- 2019 Toyota Rav4 Hybrid
The affected vehicles have a brake booster pump with an accumulator and a pump motor which contains a plastic brush holder to hold the motor brushes. It is possible that the plastic brush holder may have been manufactured improperly, causing one of the brushes to become stuck in the brush holder. If this happens, the brush would be unable to maintain an electrical connection inside the motor and may cause the pump motor to stop operating.
If the pump motor stops operating, multiple warning lights and messages will illuminate, and/or audible chimes will sound. Depending on brake fluid pressure in the accumulator and brake pedal stroke amount, braking assist could be lost completely and the Vehicle Stability Control system will become deactivated. A sudden and complete loss of braking assist while driving could increase the vehicle stopping distance and may increase the risk of a crash. Further, deactivating the Vehicle Stability Control system may cause the subject vehicles to not meet the requirements of FMVSS No. 126, paragraph S5.1.2.
Owners receiving notices will be asked to return to their dealers to have the brake booster pump inspected and replaced as necessary. Toyota’s numbers for this recall are K1L/K0L. Lexus’ numbers for this recall are K2F/KLF. The NHTSA Campaign Number is 19V544000.
Ford is asking the owners of certain 2018 Ford Escape and 2018 Lincoln MKC vehicles to return to their dealership for a problem affecting the brakes. According to the defect report, incorrect front brake jounce hoses may have been installed and could contact adjacent components during normal driving conditions. This could result in premature wear of the hoses and a potential brake fluid leak. Loss of brake fluid will increase the distance needed to stop the vehicle. Drivers will be alerted of a problem through an illuminated brake fluid warning light.
Dealers will inspect the brake hoses, replacing incorrect ones as necessary. Owners wanting more information about the problem can contact Ford customer service at 1-866-436-7332. Ford’s number for this recall is 18S04 and the NHTSA campaign number is 18V-104.
Chrysler will be contacting the owners of certain 2017 Dodge Caravan and 2017 Jeep Wrangler vehicles because of a problem that could increase the chance of a crash. According to the NHTSA defect report, the brake switches in these automobiles are more likely to malfunction, causing the rear brake lamps to continuously illuminate and allowing the transmission to be shifted out of “Park” without the brake pedal being depressed.
Drivers will be alerted of a problem through a illuminated malfunction indicator lamp, an audible warning chime and brake lights that continuously illuminate.
Chrysler will be asking owners to return to their dealers to have the brake switches replaced. Owners who would like more information about the problem can contact Chrysler customer service at 1-800-853-1403. Chrysler’s number for this recall is U09 and the NHTSA campaign number is 18V-098.
