Which has more recalls?
The 2025 Rivian R1S has more active recalls (3 vs 1). Total count is less important than severity, though — a vehicle with one critical recall and zero moderate ones is generally riskier than one with five moderate recalls.
Is an extended warranty worth it on either of these?
Both vehicles are out of factory bumper-to-bumper coverage at this point. Combined repair exposure across the top problem categories runs around $5,250 on the higher-risk vehicle. A quality service contract typically costs $1,800–3,500 over 3 years, so a single major failure usually pays for the contract. The math favors warranty coverage on whichever vehicle you choose, especially if you plan to keep it past 100,000 miles.
