2003 Subaru Forester (2nd-Gen) Common Exterior Problems

The 2003 Subaru Forester launched the 2nd generation (SG-chassis, 2003–2008) on a new Impreza-based platform, and it's now old enough that the front-end plastics and lighting show consistent wear. Here's what to look for, and what changed partway through this generation's run.

Quick answer:

• 2003–2005 is the pre-facelift range — Subaru updated the front end, grille, and taillights for the 2006 model year, so parts don't always cross that line.
• Grille — clip fatigue and UV fading on the plastic surround are common wear points.
• Headlights — yellowing and internal fogging are widely reported on this generation, especially on cars stored outside.
• Side mirrors — housing cracks and, on heated-mirror-equipped cars, wiring connector wear are the typical failure points.

Know Your Generation: 2003 Is Pre-Facelift

The 2nd-generation Forester (chassis code SG) ran from 2003 through 2008, with a facelift for the 2006 model year that updated the front fascia, grille, and taillights. A 2003–2005 Forester and a 2006–2008 Forester look similar at a glance but do not share the same front-end parts.

Before you shop for a part, confirm:

• Model year (2003–2005 pre-facelift vs. 2006–2008 facelift — grille and front bumper design differ)
• Trim level (X, XS, and the turbocharged XT — trim affects some grille and mirror trim details)
• Whether your car has heated mirrors (a common option that affects mirror part numbers)

This part commonly fits vehicles within its listed year and trim range — always confirm against your vehicle's exact trim and the product's fitment data before buying.

Grille Wear on the 2nd-Gen Forester

The pre-facelift (2003–2005) grille is a common replacement on this generation, mostly due to age-related plastic fatigue:

• Broken mounting clips — brittle tabs after two decades of heat cycling
• UV fading on the plastic surround, especially noticeable on cars parked outside long-term
• Cracked or loose emblem insert, often from a minor front-end bump or a car wash brush catching an edge

Grille styling is broadly similar across X, XS, and XT trims on the pre-facelift range, though XT (turbo) models sometimes include a hood scoop that changes the visual proportions up front — this doesn't affect grille fitment itself, but it's worth confirming your trim's hood and grille combination match if you're doing a fuller front-end refresh.

This part commonly fits the 2003–2005 pre-facelift range — always confirm against your vehicle's exact trim and the product's fitment data before buying, since the 2006 facelift introduced a different grille design.

Headlight Yellowing and Fogging

Two distinct issues get lumped together as "bad headlights" on the 2003 Forester:

1. Lens yellowing and hazing — UV damage to the outer clear-coat. Extremely common on cars this age, especially ones parked outside. It's a cosmetic and light-output issue, not a sealed-housing failure, and polishing helps only temporarily.
2. Internal fogging or moisture — condensation inside the sealed housing from a failed gasket. Light haze that clears by midday is normal; standing water or fog that never clears means the seal has failed, and a housing replacement is the correct fix rather than a polish job.

Headlights are safety equipment, and this car is often driven on rural or wooded roads at night given its outdoorsy owner base. If you can't tell surface yellowing from a failed internal seal, it's worth having a shop confirm before spending on a polish kit that won't fix a housing problem.

This part commonly fits the 2003–2005 pre-facelift range — always confirm against your vehicle's exact trim and the product's fitment data before buying, since the 2006 facelift uses a different headlight housing shape.

Side Mirror Wear

Side mirrors on the 2003 Forester fail in a couple of predictable ways:

• Cracked housings from tight parking spaces, garage pillars, or door-edge contact
• Heated mirror wiring wear — on cars equipped with heated mirrors, the connector and internal wiring can degrade with age, leading to a mirror that no longer heats or a connector that's tricky to reseat cleanly

Before ordering a mirror, confirm:

• Manual or power-adjustable
• Heated or non-heated
• Whether your trim includes a mirror-mounted turn signal (less common on this generation, but worth double-checking)

This part commonly fits [your Forester's model year and trim] — always confirm against your vehicle's exact trim and the product's fitment data before buying, since heated vs. non-heated mirrors use different connectors.

OEM vs. CAPA-Certified vs. Aftermarket

On a car approaching its 20s, many owners lean toward CAPA-certified or standard aftermarket parts over OEM, since OEM pricing and availability get harder to justify the older a car gets. Either is reasonable — confirm the listed fitment against your exact trim and pre-/post-facelift range before buying.

Do You Need to Replace It or Can It Wait?

Replace soon:

• Headlight with standing water or fog that never clears
• Grille missing enough clips that it's loose or rattling
• Mirror housing cracked enough that the glass is loose or exposed

Can wait / cosmetic only:

• Minor grille fading with no structural looseness
• Light headlight haze that clears by mid-morning
• Small mirror housing scuffs with the mirror still adjusting normally

If you're not sure which category applies, a quick shop check is a reasonable next step rather than guessing, especially before a long trip or before winter road-salt exposure starts.
