Subaru Solterra common problems and how to fix them (2023)
4 min read·Last updated: 2023-01-01·By ev.care editorial team
TL;DR
The Subaru Solterra has 5 commonly reported issues — none catastrophic, all well-understood. Most are software or wear-item related and resolve on a single workshop visit. Subaru's service network handles them under warranty; out of warranty, repair costs are predictable.
No car is perfect, and the Subaru Solterra's honest weak spots become obvious once you talk to enough owners. Across Subaru's service network and ev.care's own technicians, 5 issues come up repeatedly on Subaru Solterra units built since 2022. Reading through them is the cheapest insurance against a bad used-car deal.
What Subaru Solterra owners report first
Subaru Solterra owners report this most often during the first 18 months of ownership. Issue 1 — Same wheel hub bolt recall as bZ4X twin (MY2022-23). On the Subaru Solterra, owners typically notice this within the first 12–24 months. The diagnosis path is well-mapped: a connected scan tool reveals it quickly, and the fix is usually a documented service-bulletin procedure rather than experimental work. Issue 2 — Slow DC charging in cold conditions. On the Subaru Solterra, owners typically notice this within the first 12–24 months. The diagnosis path is well-mapped: a connected scan tool reveals it quickly, and the fix is usually a documented service-bulletin procedure rather than experimental work. For a 71.4 kWh, 365 km mid-size electric suv like the Subaru Solterra, these patterns are well within what the platform is designed to handle once the right service-bulletin steps are followed.
More Subaru Solterra fault patterns to know
Forum threads and service data both agree — this is a real issue on the Subaru Solterra, not a one-off. Issue 1 — Real-world range 18-25% below rated on highways at AC + 100 kmph. On the Subaru Solterra, owners typically notice this within the first 12–24 months. The diagnosis path is well-mapped: a connected scan tool reveals it quickly, and the fix is usually a documented service-bulletin procedure rather than experimental work. Issue 2 — DC fast charger compatibility varies by operator firmware. On the Subaru Solterra, owners typically notice this within the first 12–24 months. The diagnosis path is well-mapped: a connected scan tool reveals it quickly, and the fix is usually a documented service-bulletin procedure rather than experimental work. For a 71.4 kWh, 365 km mid-size electric suv like the Subaru Solterra, these patterns are well within what the platform is designed to handle once the right service-bulletin steps are followed.
Quieter Subaru Solterra issues that still matter
Multiple Subaru Solterra owners have flagged this, and the diagnosis is usually quick. One of the most discussed issues is "Touchscreen ergonomic lag in first 6 months — OTA-fixable" — and on the Subaru Solterra this typically shows up as inconsistent behaviour that an experienced technician can replicate on the lift. For a 71.4 kWh, 365 km mid-size electric suv like the Subaru Solterra, these patterns are well within what the platform is designed to handle once the right service-bulletin steps are followed.
Practical next steps
On a test drive, push the Subaru Solterra through stop-and-go traffic and a 15-minute highway stretch. Watch the infotainment for lag, listen for any new noises under braking, and check that regen feel is consistent. On a used Subaru Solterra, ask for the full service history and confirm any OTA updates are installed.
Related Subaru EVs

Frequently asked questions
- Are there any open recalls on the Subaru Solterra?
- Recall status changes — check the brand's service portal with the VIN before purchase. Any open recall is fixed for free, so it is actually a slight positive on a used buy: free brand-paid service on the way in.
- Should I avoid early production years of the Subaru Solterra?
- Not necessarily — but you should ask more questions. Early Subaru Solterra units more often need a software refresh and one or two warranty fixes; later batches are smoother. If you are getting a meaningful discount on an early-build Subaru Solterra, the math usually still works.
- Is the Subaru Solterra reliable overall?
- Yes — the Subaru Solterra is a mainstream EV with a well-mapped set of known issues. None of the recurring faults are catastrophic, and the brand network is set up to handle them. The reliability profile is closer to "predictable maintenance" than "lottery".
- Can ev.care diagnose Subaru Solterra faults remotely?
- Partially. For software-related issues a virtual inspection over video is enough; for suspension, bushings, or battery cooling, we send a certified Subaru Solterra technician on-site. Most diagnoses are done in a single visit.
Knowing this list is the easy part. Acting on it — booking a test drive that specifically stresses the suspect systems, asking the seller for service records, getting a pre-purchase inspection on a used Subaru Solterra — is what actually protects you. Subaru pricing is competitive, so the leverage of an informed buyer is real.
