2010 Subaru ImprezaElectrical systemAcceleration & cruise control

The speedometer and the entire dashboard goes haywire when driving. It's impossible to know what speed I'm going, no inspection yet. The cruise control light is on and won't go off. I'm not sure if it's on or not which is unfastened and could cause other issues. The check engine light goes on and off as well as the brake and ABS lights. There is no telling what could be wrong with those lights. It gets hard to brake when the brake light and the ABS light is on. Also the transmission gets stuck and I can't reverse...

the driver ) had to push the vehicle physically away from the building and cars and got away only one minute before it entirely exploded. Whether or not the problem has been confirmed or reproduced elsewhere is UNKNOWN. The fire was extinguished by firefighters and police did take a report as well. There was absolutely no warning that there was an issue prior - not even a hazard light- the only thing I noticed was my oil temp had begun to increase.

2014 Subaru ImprezaElectrical system

Cabin blower fan stopped working. Faint burned plastic smell. Starting with the blower motor, I worked backwards. The Blower Motor Resistor showed significant wear, which I replaced. After checking or replacing all other components, I realized that it was likely the AC Control Unit. I took it out and the electrical issue is so bad that the plug has melted to the harness. I found plenty of online videos and forums which helped me diagnose the problem in my own car. This is a fire hazard, and considering how many...

2019 Subaru ImprezaElectrical systemDriver assistance

2019 Subaru Impreza has experienced intermittent and now persistent failures involving the factory EyeSight driver assistance system. Prior to complete failure, the EyeSight system would randomly disable and re-enable while driving. Adaptive cruise control and related safety features became unreliable and would intermittently stop functioning. The issue worsened over time and eventually resulted in repeated "EyeSight Off" warnings and multiple system fault messages. Vehicle diagnostic scans showed repeated U1235...

"Lost communication with EyeSight" faults across multiple modules, including ABS, steering, transmission, and instrument cluster systems. Additional communication and airbag indicator-related faults were also present. The windshield was recently replaced due to a crack located near the EyeSight camera area. Subaru service personnel stated that EyeSight systems are extremely sensitive to windshield specifications and calibration requirements, and that aftermarket windshields may prevent proper operation or calibration of the system. Subaru also indicated that EyeSight calibration equipment is highly specialized and expensive, and that repair costs may not be practical relative to the vehicle value. Despite attempts to reset the vehicle systems and inspect the issue, the EyeSight system continues to malfunction and remains disabled. Because EyeSight controls important driver assistance and collision-avoidance features including adaptive cruise control, forward collision warning, lane departure warning, and automatic emergency braking, this issue creates significant safety concerns. The intermittent nature of the failure, repeated communication faults, and inability to reliably restore system operation raise concerns regarding the long-term reliability and serviceability of Subaru EyeSight systems.

2017 Subaru ImprezaElectrical system

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

My entire dash went out. Nothing worked. This car has only 3500 miles on it. I got danger signs and it said to stop driving the car. Danger. I also got messages in my e-mail I think from Starlink to stop driving the car and bring it in to service. It was dangerous. Service had it for two weeks. They didn't know what to do.

I do not feel safe in it.For something so new these emergency problems should not be happening. I want a cash back or give me another car.They had it for two weeks and gave me no explanation what happened. It is not a safe car. I hope Customer Care will help me. Someone has to.

2017 Subaru ImprezaElectrical systemLightsVisibility & wipers

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!(?)

2018 Subaru ImprezaElectrical system

My vehicle has repeatedly displayed a "low tire pressure" warning despite having been serviced twice for this issue. In addition, there is an open case with Subaru of America regarding ongoing performance concerns - fuel tank?! In addition, I have reported both verbally and in writing to the dealership that my car often loses power when driving uphill and, at times, runs unevenly or hesitantly - similar to an engine stutter or sputter. Most recently, multiple problems occurred simultaneously. The low tire pressure...

warning remained on, my cell phone was no longer recognized or paired with the vehicle and would not charge, part of the clock display stopped illuminating, and then the vehicle suddenly began to shake. Within seconds, all dashboard warning lights turned on and the engine shut off entirely. This happened so rapidly that I had no time to react. Fortunately, I had pulled over the car; otherwise, this incident could have resulted in a serious crash with me behind the wheel. Although no prior warning lights had appeared, I was later informed that the vehicle had a cracked ignition coil and a dead battery - despite the car having relatively low mileage and there being two recalls related to this issue. The new manager went above and beyond to assist me during this ordeal and I am beyond grateful for everything - Subaru of America is lucky to have him on staff!! However, as of today, I still have not received a clear explanation of what caused this failure or what risks may remain if I continue driving the vehicle. My understanding is that ignition coils should run for 80K - 100K. I am aware that others have experienced similar problems, and I request that this matter be thoroughly addressed before it results in a potentially preventable, yet serious accident.
