Subaru Cases Under Montana Lemon Law
Subaru cases in Montana — a top-selling brand — Boxer engine oil consumption, CVT failures, EyeSight, and Solterra EV defect patterns, with cold and mountain factors.
Subaru is one of Montana’s top-selling brands — its standard AWD fits Montana winters and mountain roads, with high per-capita ownership. Outback, Crosstrek, Forester, and Ascent are everywhere. Cases are pursued under the Montana Lemon Law, the CPA, and Magnuson-Moss.
Common Subaru defect patterns
- Boxer engine oil consumption (FB20/FB25) — long-standing pattern with class-action history.
- CVT failures — Outback, Forester, Crosstrek, Ascent (worse on mountain grades).
- EyeSight system defects — false braking, calibration drift (snow/de-icer-spray can affect sensors).
- Ascent / Outback transmission issues.
- Solterra EV — wheel-loss recall (early build), cold-weather charging/range.
- Starlink infotainment crashes.
Montana Subaru market
- Outback / Crosstrek / Forester dominate winter-driving and outdoor culture.
- Ascent family segment.
- Among the higher per-capita Subaru ownership in the mountain west.
Cold and mountain factors
- Boxer oil consumption can worsen with cold short trips.
- CVT stress on long mountain grades and with towing.
- EyeSight false-braking is a safety concern — supports a CPA theory; snow and de-icer spray can foul the sensors.
- Mag-chloride de-icer drives electrical and brake corrosion.
Proving the case
- Repair orders across attempts.
- Boxer oil-consumption class-action history, CVT TSBs, EyeSight calibration bulletins.
