2017 Subaru Impreza Complaints

ELECTRICAL SYSTEM — Filed 02/07/2026

I am filing a safety complaint regarding an Engine Control Module (ECM) failure in my 2017 Subaru Impreza and the handling of a prior recall repair. Dealership records show that a recall repair (WRE21 – ignition coil recall) was completed in June 2021. At that time, the dealership documented that the ECM calibration was up to date and functioning properly. However, I later experienced a check engine light and drivability concerns. Diagnostic records from February 2026 indicate: •Camshaft slow response codes •Persistent sensor issues •A technician recommendation to replace multiple components, including the ECM, stating that codes were “burned into the ECM” The dealership has since attempted to attribute the ECM failure to “engine sludge” and lack of maintenance. Concern with Dealership Explanation: This explanation is inconsistent and raises serious concerns: •Engine sludge is a mechanical lubrication issue and does not directly cause an ECM (electronic control module) to fail or become “burned.” •The ECM is an electronic unit, and failure typically results from electrical defects, internal faults, or manufacturing issues—not oil sludge. •The dealership has not provided technical evidence showing how sludge could damage or “burn” the ECM. •This appears to be an attempt to shift responsibility away from a potential defect or improperly completed recall repair. Safety Concern: The ECM is critical to safe vehicle operation. A failure can result in: •Engine malfunction or reduced power •Unpredictable vehicle behavior •Increased risk while driving If ECM failures are being misdiagnosed or incorrectly attributed to maintenance issues, this could allow serious safety defects to go unaddressed. Requested Action: I request that NHTSA: 1.Investigate whether ECM failures are being improperly attributed to maintenance issues such as engine sludge. 2.Review whether the recall repair (WRE21) was properly completed and whether it is related to thi

I noticed that visibility at night was poor. I was pulled over by the police and give a warning that my headlight was out and told to get it fixed. I thought it may be as simple as a bulb but was told the entire left headlamp assembly had to be replaced at a cost of more than $2,000. Just days later my Dealership send me a service notice which also stated that the left headlamp should be inspected. This was after I had already had it replaced at a local garage. The dealership confirmed that their was a recall but when I tried to get reimbursed by Subaru thru the safety recall WRG-22/NHTSA 22V624000 they said my vin# was excluded from the recall!(?)

[XXX] 2017 Subaru Impreza VIN [XXX] Cruze control error. Will it make brake lights fail if not repaired? go look in your database and see if Impreza has more than normal rear end collisions? What else is on bus that might be damaged by spike? Braking? Antilock? Lights? Why is this NOT a recall? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

AIR BAGS,FORWARD COLLISION AVOIDANCE — Filed 08/02/2025

1. Any and all airbags failed to deploy. The car is currently parked in my garage and is available for inspection. The insurance company has declared the car a "total loss," and would like to tow it away as soon as possible. 2. The driver had a concussion and whiplash after their forehead hit the steering wheel. 3. No safety inspector has inspected the car yet. The insurance appraiser has inspected the car for the insurance company. 4. There were no warnings or dashboard lights indicating that the airbag had a problem and would fail to fully deploy.

POWER TRAIN — Filed 03/20/2023

Premature failure of wheel bearings. Both rear wheel bearings had to be replaced after only 54,192 miles. Technician indicated that replacements were upgraded "sealed" systems. At 73,712 miles the front driver's side wheel bearing was also replaced by the dealer after the same symptoms of excessive noise and poor mileage occurred. Concern is that high resistance in the failing bearings creates a lot of heat and could eventually cause catastrophic failure. In 40+ years of driving and owning cars with mileage accruals up to 229,000, this is the only one that ever required a wheel bearing replacement. This, and the technician's reference to upgraded bearings makes me believe that this is a manufacturing defect that should have been covered by a recall.

UNKNOWN OR OTHER — Filed 08/05/2025

After reading forums online and my own experience I’m convinced the Subaru sun visors are improperly installed or fitted and pose a danger to drivers and those on the road. The sun visors on the driver and passenger side are incredibly loose and prone to falling off while I’m driving. I cannot use it to deflect sun because it will fall off while I’m driving - creating incredibly dangerous driving conditions. It has fallen in my lap but I’m afraid it might fall down to where the pedals are and cause further issues. This has been an issue since I purchased the vehicle in 2019 and happens almost weekly It doesn’t appear that Subaru sells the parts separately so replacing it would be costly.

I hit the guard rail going 35 mph on an exit ramp because of the low visibility because of the safety recall. I went to get the recall fixed when I found out and they refused to fix the recall because my bumper is messed up.
