When researching a used 2017 Subaru Impreza, it is essential to move beyond the standard praise of standard all-wheel drive and examine the specific mechanical nuances of that model year. While generally regarded as a reliable compact car, the 2017 model introduced specific changes and inherited certain quirks from its predecessors. Understanding these common 2017 Subaru Impreza issues allows potential buyers to make informed decisions and avoid unexpected repair costs down the line.
Common Mechanical and Electrical Glitches
The 2017 model year sits in a transitional period for Subaru's infotainment and sensor systems, leading to a few recurring complaints documented by consumer reports and owner forums. These issues, while not universal, appear with a frequency that warrants investigation during a pre-purchase inspection. Addressing these early can save owners significant frustration and repair bills later in the vehicle's lifespan.
Infotainment System Headaches
One of the most frequently cited 2017 Subaru Impreza issues involves the touch-screen display and the associated Starlink multimedia system. Owners often report that the interface is slow to respond, menus are confusing, and the system can occasionally freeze entirely, requiring a manual reset. Furthermore, the integration of Apple CarPlay and Android Auto, while available, can be finicky and disconnected, limiting the usability of modern smartphone connectivity for navigation and music streaming.
Sensor and Warning Light Problems
Another prevalent category of issues stems from the vehicle's various sensors. The EyeSight driver-assistance package, a key feature of the 2017 model, relies on cameras and radar that can malfunction or provide inaccurate readings. This often triggers warning lights on the dashboard, such as the Adaptive Cruise Control or Pre-Collision System indicators, even when the systems are functioning correctly. Resetting these systems or cleaning the cameras usually resolves the issue, but the frequency of these alerts can be a source of constant anxiety for owners.
Mechanical Underbody Concerns
Shifting focus from the dashboard to the undercarriage, the 2017 Impreza shares a common weakness with many of its Subaru siblings regarding the chassis and suspension components. These mechanical issues are critical to address because they directly impact handling, safety, and the longevity of the vehicle.
CVT Transmission Hesitation
The Subaru Impreza utilizes a Continuously Variable Transmission (CVT), which provides smooth power delivery but is not without its drawbacks. A specific complaint regarding the 2017 model is a hesitation or "rubber band" feeling during acceleration. Drivers may notice the engine revving without a corresponding increase in speed, particularly when climbing a hill or merging onto a highway. This issue can indicate excessive wear on the CVT belt or low fluid levels, which require immediate attention to prevent complete transmission failure.
Rear Differential and Axle Wear
Over time, the rear differential and half-shaft axles on the 2017 Impreza can wear out, leading to distinct clicking or popping noises when turning corners. This is often attributed to the constant torque vectoring managed by the rear differential. If left unaddressed, the wear can progress to a point where the axle boots tear, leading to grease leakage and eventual joint failure, which would necessitate a very expensive repair involving the axle assembly or differential.
Exterior and Interior Maintenance Quirks
Beyond the powertrain and electronics, owners of the 2017 model year report specific maintenance quirks related to the vehicle's design and materials. These issues affect the daily ownership experience and the long-term value of the car.
