Subaru Warranty Explained (by a Former Warranty Administrator)
Quick answer
Subaru's new-vehicle warranty is 3 years/36,000 miles bumper-to-bumper and 5 years/60,000 miles on the powertrain, with 5-year/unlimited-mile rust perforation coverage and roadside assistance for 3 years/36,000 miles. Hybrid and Solterra EV batteries carry 8 years/100,000 miles — 10/150 in CARB states.
Subaru sticks to the industry baseline: 3/36 basic, 5/60 powertrain, five years of rust-through coverage with no mileage cap. No long-warranty marketing, no included maintenance. For a brand built on boxer engines and standard all-wheel drive, the booklet is almost aggressively ordinary — which puts the weight on knowing how Subaru handles the claims, not the terms.
Here's the claims-desk reality: Subaru's historical trouble spots — head gaskets on older EJ engines, oil consumption on early FB engines, CVT behavior — mostly surface past 36,000 miles, which makes the 5/60 powertrain warranty and Subaru's extension programs the documents that matter. Subaru extended CVT coverage to 10 years/100,000 miles on many 2010s models and ran an oil-consumption settlement with extended coverage on others. Before paying for any engine or CVT repair on a Subaru under 100,000 miles, have a dealer run the VIN for open extensions — this brand has more quiet coverage programs than most.
The other Subaru-specific habit worth building: oil-level checks between changes, documented. On engines with any consumption history, a claim often requires a dealer-supervised consumption test (measured oil loss over a set mileage). Owners who show up with dated receipts and their own oil-log get through that process much faster than owners reconstructing history from memory. AWD also adds one quiet rule — mismatched tire circumference can damage the center differential/clutch pack, and that damage is chargeable, not warrantable. Replace tires in fours.
Coverage at a glance
Years OR miles — whichever comes first. US-market terms.
Basic (bumper-to-bumper)
3 years / 36,000 mi
Defects in materials or workmanship across the vehicle: EyeSight cameras, Starlink electronics, A/C, sensors, power equipment. The warranty that pays for most everyday claims.
Powertrain
5 years / 60,000 mi
Boxer engine, transmission (including the Lineartronic CVT), and the symmetrical AWD system internals. Internal lubricated parts only — accessories and sensors are basic-warranty items.
Rust perforation
5 years / Unlimited
Body panels rusted through from the inside out. Surface rust from chips, scratches, or road damage is excluded — relevant for a brand whose owners live where roads get salted.
Roadside assistance
3 years / 36,000 mi
24/7 towing, jump starts, flat-tire, lockout, and fuel-delivery service through the basic warranty period.
Hybrid/EV battery
8 years / 100,000 mi
High-voltage battery and hybrid/EV system components on Crosstrek Hybrid, Forester Hybrid, and Solterra. CARB states extend qualifying coverage to 10 years/150,000 miles.
What the claims counter wants you to know
- Run the VIN for extension programs before paying out of pocket: Subaru extended CVT warranties to 10 years/100,000 miles on many 2012–2018 models and provided extended oil-consumption coverage on certain FB-engine cars. These ride on top of the standard 5/60 and follow the car.
- Maintenance records are your armor, and with Subaru add an oil log. Magnuson-Moss protects servicing anywhere, but consumption and engine claims move faster — and goodwill gets approved more readily — when you can document levels between changes, not just the changes themselves.
- Replace tires in matched sets of four. Subaru's symmetrical AWD is sensitive to circumference differences; running one new tire with three worn ones can cook the center coupling, and that failure reads as owner-induced damage at the claims desk, not a defect.
- Powertrain ≠ everything past 36k: EyeSight cameras, sensors, the alternator, A/C, and head-unit electronics are 3/36 basic items. The boxer engine's spark-plug and valve-cover service access is also a labor-cost surprise — but labor on a covered claim is Subaru's problem, not yours.
- All Subaru factory coverage transfers free to subsequent owners for the remaining term, including extension-program coverage tied to the VIN.
Frequently asked questions
- Does the Subaru warranty transfer to a second owner?
- Yes — basic, powertrain, rust-perforation, and hybrid-battery coverage all transfer automatically and free for the remaining term. So do VIN-based extension programs like the CVT and oil-consumption extensions, which is worth verifying with a dealer when buying a used Subaru.
- Is the Subaru CVT covered, and was its warranty extended?
- The Lineartronic CVT is a powertrain component covered 5 years/60,000 miles. On many 2012–2018 models, Subaru extended CVT coverage to 10 years/100,000 miles via service program — coverage that follows the car. A dealer can confirm by VIN in minutes; always check before authorizing a CVT repair.
- Can I service my Subaru outside the dealer without voiding the warranty?
- Yes — independent shops and DIY are protected by federal law; Subaru can only deny a claim by tying it to a maintenance failure or a modification that caused it. Keep dated receipts with mileage and oil spec, and on consumption-prone engines, keep your own oil-level log between changes.
- Does the warranty cover Subaru head gasket or oil consumption problems?
- Within 5/60, internal engine failures including gasket defects are powertrain claims. Beyond that, Subaru's oil-consumption settlement extended coverage on certain 2011–2015 FB-engine models, and dealers handle borderline cases with a documented consumption test. If your engine uses oil, start that paper trail at the dealer now — undocumented consumption is unprovable consumption.
- What voids a Subaru warranty?
- Voiding the whole warranty requires extremes like a salvage title. Practical denials are specific: no maintenance records, mismatched tires that damaged the AWD system, off-road or accident damage, or performance modifications (a tuned WRX is the classic case) shown to have caused the failure. Stock, documented, and four matched tires keeps nearly everything intact.
