2018 Subaru Outback · 5th Gen (2015-2019)

2018 Subaru Outback Problems: Owner-Reported Issues, Recalls & Common Fixes

The 2018 Outback is mid-5th-gen with the 2.5L FB25 boxer (or optional 3.6R H6) and Subaru's TR690 Lineartronic CVT. The infamous EJ25 head gasket issue is GONE - that's an EJ-series problem, not FB-series. However, oil consumption on the FB25 was a class-action settlement (Yaeger v. Subaru), and battery drain complaints persist.

Reliability: 3.9/5 5th Gen (2015-2019)
⚠ Generally Reliable, Watch Oil

No more EJ25 head gasket. FB25 is more reliable but had its own oil-consumption class action (Yaeger v. Subaru). Confirm any oil-consumption test or short-block work.

#1 · Class Action
FB25 Oil Consumption
40K-80K mi · Est. $0 (covered) or $3,500+

Subject to Yaeger v. Subaru class-action settlement (covers 2013-2014 originally; some 2018 units affected via piston ring updates). Subaru will test consumption at warranty mileage. >1qt/1200mi qualifies for short block.

TR690 CVT Shudder
60K-110K mi · Est. $200-400 fluid / $4K replace

Subaru extended CVT warranty to 10yr/100K on certain MYs. The TR690 is more reliable than the smaller TR580 but still requires fluid service every 60K. Shudder = first warning.

Windshield Cracks (EyeSight)
Any mileage · Est. $800-1,400

Subaru windshields crack easily, often spontaneously. EyeSight requires recalibration ($150+) on replacement, so total cost is high. Class action Powell v. Subaru settled with limited reimbursement.

💬 Frequently Asked Questions About the 2018 Subaru Outback

Does the 2018 Outback have head gasket problems?

No. Head gaskets are an EJ25 (older) issue. The 2018 uses the FB25 with timing chain and revised head design, which doesn't share the EJ25's head gasket weakness.

Is the 2018 Outback CVT reliable?

The TR690 CVT is more reliable than the smaller TR580. Subaru extended the CVT warranty to 10yr/100K on certain model years. Fluid service every 60K is essential.

Does the FB25 burn oil?

Some do. The Yaeger class action covered earlier MYs but Subaru continued updating piston rings. If your unit consumes more than 1 qt per 1,200 miles, ask for a consumption test under powertrain warranty.

Why do Subaru windshields crack?

Thinner laminated glass paired with EyeSight camera bracket creates stress points. Replacement windshields with EyeSight recalibration run $800-1,400. A class action settlement provided limited reimbursement.

Should I buy a 2018 Outback?

Yes if oil consumption history is clean and CVT fluid has been serviced. The 3.6R H6 avoids FB25 oil consumption entirely but is harder to find.

How long will a 2018 Outback last?

With maintenance, 200,000-250,000 miles is realistic. The FB25 outlasts the older EJ25 in real-world service.
