Camden, NJ – Feb 18, 2022 – Subaru has remedied issues with 359,708 vehicles including the 2018 Subaru Impreza and the 2018 Subaru Crosstrek dealing with a programming failure on the engine control module or ECM. Additionally, none of these models have been categorized as unreachable and 4,424 have been removed from the recall. All these Subaru models with ECM software issues were remedied between the second and fourth quarter of 2021.

Camden, NJ – May 11,  2021 – Subaru (OTCMKTS: FUJHY) has recalled 466,205 vehicles with an incorrectly programmed Engine Control Module (ECM), which is a component that controls over 100 elements in these cars. The issue may cause the car to stall, potentially leading to an accident.

The Subaru ECM Recall includes the following vehicles:

• 2017 Subaru Impreza
• 2018 Subaru Impreza
• 2019 Subaru Impreza
• 2018 Subaru Crosstrek
• 2019 Subaru Crosstrek

The defective part of the vehicle is the ignition coil,  part number 22433AA741.

Recall summary  

Ignition coils are part of the car ignition system and convert the voltage of the car battery into energy needed to start the car. Due to faulty programming, the ECM is going to continue “instructing” the coils to do their job even after the engine is off. This may result in the coils short-circuiting. If this occurs when the car is in motion, the vehicle may stall, increasing the risk of a crash.

This recall follows on the heels of a 2019 recall of the same cars for the same exact issue. It is being conducted again as Subaru discovered that the ECM reprogramming that was done last time was not sufficient to fully remedy the issue.

Safety risks

Stalling while driving may lead to potentially dangerous situations, especially if it happens in high-speed or dense traffic. Stalled cars are very dangerous and kill over 300 people a year on average, as reported. For tips on what to do if your car stalls while you’re driving it, please see this recent Kia article. 

Warning signsSubaru recall

During the motion of the vehicle, when the occupants feel “irregular vibration.” This may mean that the vehicle is about to lose power.

Other similar recalls

In October of 2019, nearly half a million Subarus were recalled due to a stalling risk.  Subaru of America recalled Impreza and Crosstrek vehicles – whose model years stretch from 2017 to 2019 – that may have faulty engine control modules. Specifically, despite the engine being turned off, the ECM may continue to run, a circumstance that has the potential to cause a short circuit or a blown fuse. This could lead to an accident if either of these outcomes takes place while motorists are traveling.

The repair

Dealers will rectify the flaws in the programming of the ECM and will replace ignition coils and – in some cases – the front exhaust pipes as well. This will be carried out free of charge. The recall began on April 16.
