Subaru Uncharted 1 — Problems & Common Faults
Weaknesses, engine ratings and buying advice
The Uncharted is Subaru's first genuine mass-market compact EV and is technically closely related to the Toyota C-HR+ — both share the e-TNGA platform along with motor and battery architecture also found in the Solterra. Buyers comfortable with that shared lineage get a comparatively affordable electric SUV with three cleanly staggered drivetrain options: a lean base version with a 57.7 kWh battery and around 455 km WLTP range, a longer-range front-drive version with a larger pack (roughly 72 kWh net, marketed as a 77 kWh pack gross) and nearly 600 km rated range, and an all-wheel-drive version with two motors, 343 hp, and a roughly five-second sprint to 100 km/h. Charging tops out at 150 kW DC and 22 kW AC, with the 10-80% top-up taking 28 to 30 minutes depending on the source — solid but not a class leader in the current market. Subaru covers the high-voltage battery for eight years or 160,000 km at a minimum 70% remaining capacity; buyers who keep to the prescribed service intervals at an authorized partner can extend coverage to up to ten years or 200,000 km via the SubaruSafe10 package. Neither the manufacturer nor the trade press has disclosed the actual cell chemistry so far, and solid information on the cell supplier and chemistry for this specific model is still missing. Early test drives praise the balanced chassis, the unusually serious off-road ability of the all-wheel-drive version with Grip Control and an under-body camera, and the tidy interior with a large central display and classic rotary dials for climate control. Criticism, on the other hand, clusters around practicality and polish: there's neither a frunk nor a glovebox, rear legroom is tight for taller passengers, the touchscreen glares heavily in sunlight, the steering feels heavy with a flattened wheel rim that takes getting used to, and driver-assist systems like adaptive cruise control and lane-centring aren't yet running smoothly according to early reviews. On the all-wheel-drive version, traction control also intervenes early and noticeably. Naturally, there is no meaningful long-term or workshop track record yet on the drivetrain, battery aging, or electronics at this stage of the launch — the Uncharted has only been orderable since early summer 2026, and any real-world high-mileage experience simply doesn't exist yet. Early buyers get a technically largely unused but also unproven car, cushioned by a solid warranty as a safety net. Anyone wanting more certainty should wait for the first one to two years of ownership experience to accumulate.
Engine Overview
The Subaru Uncharted 1 is available with 3 engine variants — from 167 to 343 hp.
Permanently excited AC synchronous motors from the shared e-TNGA component family also used in the Toyota bZ4X and Subaru's own Solterra — here in a revised version with a larger battery lineup and higher charging power. Front-drive versions use a single motor, while the all-wheel-drive variant runs two separate motors on the front and rear axle with no mechanical link, coordinated purely through software (electronic torque vectoring instead of a classic transfer case). Being brand new to the market, there is no meaningful long-term data yet on bearings, power electronics, or cell aging. The predecessor platform in the first-generation Solterra/bZ4X mainly showed teething problems with charging software and the 12-volt electrical system, not structural drivetrain failures. Whether those software issues have been resolved in this revised version cannot yet be judged at this stage of the market launch. Early adopters are buying into technically unproven territory — warranty coverage and dealer network cushion the risk, but the track record of an established combustion engine simply is not there yet.
No known weaknesses documented.

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Driver-assist systems (ACC/lane-centring) still immature Early test drives found the adaptive cruise control and lane-centring functions don't always work together smoothly, showing up as jerky regulation and occasional unwanted intervention. A software update could still address this in the field. Symptoms: Cruise control regulates jerkily, lane-centring corrects imprecisely or intervenes unexpectedly. | Low | |
| Traction control too restrictive on the AWD model Under hard acceleration, the AWD version's traction control intervenes early and firmly, giving the motors little leeway, so power is noticeably cut back instead of allowing some wheel slip. Symptoms: On a full-throttle launch the system noticeably cuts power, and the traction control light flashes even under moderate acceleration from a stop. | Low |
