Subaru of America have decided that a defect could exist in the suspension of certain 2021 Subaru Impreza vehicles. Owners are advised to NOT drive their vehicle until the repair can be completed.

In June 2021 Subaru opened an investigation into the 2021 Impreza, after receiving a field report of a partially separated lower control arm. In August a second field report was issued with a similar condition as the previous report. The vehicle production dates were two (2) days apart and the LOT number stamped on the control arm were the same. As a result of the joint investigation with the supplier, 75 left front lower control arms containing a specific LOT number were identified as potentially containing an improper weld. An improper weld in this location could lead to a partial separation of the lower control arm from the cross member. If this partial separation occurs, the tire could contact the wheel well structure and the driver could lose control of the vehicle.

Description of the Cause: Equipment on the control arm assembly line was damaged, resulting in contact between the part ejector rod and the welding torch. This interference caused the welding torch to be unable to trace the proper welding path and resulted in an incomplete weld at the joint.

For all of the potentially affected vehicles, Subaru dealers will inspect the LOT number stamped on the left front lower control arm. If the control arm contains a specific LOT number, the part will be replaced. Until the inspection/remedy is completed, customers will be instructed not to drive their vehicle and to make arrangements with their Subaru dealer to have the vehicle inspected. Subaru’s number for this recall is WRI-21 and the NHTSA campaign number is 21V-675.

Subaru will be contacting the owners of certain 2019 model cars and SUVs because of a problem affecting the fuel system in their vehicles.

According to the defect report, the fuel pump in these vehicles may have an impeller that was manufactured with a density that does not meet the manufacturer standards. If the impeller is exposed to solvent drying for extended periods of time, it could develop cracks that would lead to excessive fuel absorption. Over time the impeller could deform and interfere with the body of the fuel pump. If the fuel pump stops working, the check engine warning will illuminate, the engine will run roughly and could stall without the ability to restart.

Vehicles Affected
2019 Subaru Ascent
2019 Subaru Impreza
2019 Subaru Legacy
2019 Subaru Outback

Dealers will correct the problem by replacing the low pressure fuel pump. Subaru’s number for this recall is WRD-20 and the NHTSA campaign number is 20V-218.

Subaru will be contacting the owners of certain 2019 Ascent, Crosstrek and Forester SUVs regarding a problem affecting the engine in their vehicle.

According to the defect report, the material used for the PCV valve case was changed from aluminum to steel on the engine production line beginning October 2018. The difference in metal combined with heating and cooling experienced during regular vehicle use could cause a gap to develop between the PCV washer and valve case. In addition, other components surrounding the PCV case could press into the case, potentially contributing to the separation of the valve components over time. If this happens, oil will enter the engine combustion chamber, changing the appearance and/or amount of tailpipe exhaust. If the vehicle continues to be driven under these conditions, drivers may experience a complete loss of engine power.

Dealers will inspect the PCV valve, and if the valve has separated, the short block engine will be replaced. Subaru’s number for this recall is WUW-08 and the NHTSA campaign number is 19V-856.

Subaru will be contacting the owners of certain 2017 Impreza vehicles regarding a problem affecting the fuel system. Due to a software programming issue within the engine control unit, the operating threshold of the radiator fan used to cool the fuel temperature is not set low enough for winter blend fuels. A combination of winter fuel, warm temperatures and low speed or stopped driving conditions may cause the fuel to vaporize prematurely. Premature vaporization causes a decrease in fuel pressure, rough idling, a no start condition or an engine stall. In some cases, if the engine were to stall, the driver may be unable to restart the vehicle for a certain period of time.

Dealers will correct the problem by reprogramming the engine control unit to turn the radiator cooling fan on at a lower temperature. Owners wanting more information about the recall can contact Subaru customer service at 1-800-782-2738. Subaru’s number for this recall is WTP-75 and the NHTSA campaign number is 17V-216.

A small number of 2017 Subaru Legacy and 2017 Subaru Outback owners will be contacted by the manufacturer regarding a problem affecting the safety restraint system. According to the defect report filed with the NHTSA, the knee guard bracket may have been misaligned with the steering beam at the time of welding. If the bracket has not been properly attached, the knee guard may not restrain the occupant under certain conditions.

Subaru will notify owners, and dealers will inspect the knee guard welding, replacing the beam as necessary. Owners wanting more information about the problem are asked to contact Subaru customer service at 1-800-782-2783. Subaru’s number for this recall is WTL-72 and the NHTSA campaign number is 16V-716.

Subaru will be contacting owners of certain 2017 Subaru Outback vehicles regarding a problem affecting brakes and suspension. According to the defect report, the bolts used to attach the front brake calipers, wheel hubs and the right stabilizer clamp may not have been sufficiently tightened. Drivers will be alerted to a problem by a rattling or clunking sound from the front wheel area, especially when brakes are applied. If the attaching bolts loosen or detach, the related components would also become loose and could possibly detach. The vehicle may become unstable and/or no longer provide sufficient braking capability. Continue reading

Certain 2015 Subaru Legacy and Outback vehicles may fail to comply with the Federal Motor Vehicle Safety Standards for electronic stability control (ESC). Due to the inappropriate handling of a brake fluid storage tank at Subaru’s manufacturing plant, the brake fluid used in these vehicles may contain excess moisture that could cause a gelatinous material to form in the brake system. The valve filter in the dynamics control system could become clogged making the ESC ineffective in preventing
loss of vehicle control. Continue reading

Subaru will be repairing approximately fifty thousand 2016-2017 Legacy and 2015-2017 Outback vehicles for a manufacturing error affecting the steering. According to the defect report, the incorrect setting of a tool used in production of the steering column could result in an improper machining condition. As a result, the steering column shaft may not engage leaving the steering wheel to freely rotate and loss of steering ability. Continue reading
