The fourth-generation Subaru Impreza was available in a variety of trim levels and body styles, and was produced from 2012 to 2016. This generation introduced a new body design as well as an updated engine known as the FB20, improving fuel efficiency and reducing emissions. Despite these improvements for the 4th generation, owners and mechanics have noted a number of common issues on the Subaru Impreza. Below is an overview of some of the most widely reported service, maintenance, and reliability concerns for the 2012–2016 Subaru Impreza.
Engine Issues
- Excessive Oil Consumption: Some engines consume more oil than anticipated, often due to poorly sealed piston rings or improper break-in procedures when the vehicle was new. Regular oil checks is crucial to avoid engine damage.
- Valve Springs: Some Impreza engines were subject to a recall for weak valve springs, which could crack and cause engine stalling or damage.
Transmission Issues
- Shuddering or Hesitation: Subaru’s CVT transmission generally provides smooth operation, but some drivers note occasional shuddering when starting from a stop or under light throttle.
- Fluid Degradation: Like any transmission, both the CVT and manual transmissions rely on clean, properly maintained fluid. Over time, contaminated or degraded fluid can lead to slippage or hesitation.
Electrical Issues
- Brake Light Failure: Some vehicles had issues with the brake light switch sticking or failing, preventing the brake lights from illuminating or causing the ABS lights to illuminate on the dashboard. This can cause a serious road hazard, so the brake lights should be inspected regularly.
- Battery Drain: Owners occasionally report shorter battery life, potentially linked to electronics staying active longer than intended or cold-weather drain. Ensuring all interior lights and accessories are turned off before leaving the car can help mitigate this issue.
Suspension and Steering Issues
- Sway Bar Bushings: Over time, sway bar bushings and end links can wear out, leading to clunking or rattling noises over bumps. Replacing these components or lubricating them (if undamaged) can restore a quieter and smoother ride.
- Steering Wheel Vibration: Some owners report steering vibrations at highway speeds, often traced to tire balance, bent wheels, or alignment issues. Regular tire rotations and proper alignments are key to preventing uneven tire wear and vibrations.
Paint and Rust Issues
- Thin Paint: Many Subaru Impreza owners report that the paint can chip easily, particularly around the hood or wheel arches.
- Rust Prone Areas: In salt-heavy regions, watch for early signs of corrosion on the underbody, around wheel wells, and near exposed metal edges. Regular washes (especially after winter driving) and regular underbody inspections help reduce rust.
Maintenance Tips for 4th-Gen Subaru Impreza Owners
- Oil Checks and Changes: Be proactive about checking oil levels regularly, especially if your vehicle has high miles. Stick to Subaru’s recommended oil change intervals, or at least once per year.
- Regular Fluid Services: Regularly check and replace your transmission fluid, brake fluid, and coolant. Proper fluid maintenance is crucial for your vehicle’s longevity.
- Tire Rotations: Subaru’s all-wheel-drive systems require consistent tire wear for safety and performance. Rotate tires at recommended intervals (often 6,000–8,000 miles) and ensure the alignment is within spec.
- Inspect Suspension Components: If you hear knocking or rattling over bumps, have the sway bar bushings, strut mounts, and other suspension components checked sooner rather than later.
