Rivian Adventure Quad
Four Bosch-designed permanent magnet AC motors, one per wheel, 623 kW combined. Each pair — front 309 kW / 560 N·m, rear 310 kW / 671 N·m — runs through separate ZF single-speed gearboxes. True per-wheel torque vectoring with millisecond slip detection: the system reads each wheel independently and redistributes torque before a slide develops, not after. No center diff, no Torsen, no transfer case — the software is the drivetrain. Early 12V auxiliary battery was the chronic failure point: constant system wakefulness drained it overnight, stranding owners. Addressed via OTA deep-sleep mode in 2023 and service campaign RCA-26-24-002-1. Drive unit failure rate (~12% per owner polls) is the unavoidable asterisk — Bosch motors, gearboxes, and inverters come as a sealed assembly, replacement costs $4,000–12,000. Covered under 8-year/175,000-mile powertrain warranty. Gen1 trucks from 2021–2022 carry the most early-production exposure.
The first. No seriously — the actual first.
RJ Scaringe spent 12 years in near-total stealth — from a Florida garage in 2009 to the Normal, Illinois factory floor in 2021 — to deliver the world's first production electric pickup truck. The R1T didn't arrive to compete with the Cybertruck or Lightning; it arrived before either existed. Four Bosch motors, one per wheel, 623 kW, per-wheel torque vectoring that reads slip in milliseconds. Zero to 60 in under 3 seconds in a truck with an 11 cu-ft Gear Tunnel, a compressed air outlet, and Drift Mode. The Hummer EV arrived heavier and slower. The Lightning arrived three seconds behind on a drag strip. Tank Turn got cancelled before production; everything else stayed.
Engine Weaknesses 3
Forum polls document roughly 12% drive unit failure rate among Gen1 Quad Motor owners. Bosch-supplied motors, gearboxes, and inverters come as a complete assembly — Rivian replaces the whole package. Turnaround 1-2 weeks, loaner provided. Covered under 8-year/175,000-mile powertrain warranty. Multiple owners report needing a second replacement of the same unit.
Symptoms: Warning message on display, speed limited to 40-42 mph, loss of power on one axle
Primarily affects 2021-2023 builds. The 12V battery drained overnight due to constant system wakefulness, leaving owners with a dead vehicle in the morning. Rivian addressed this in 2023 via OTA update (deep sleep mode) and service campaign RCA-26-24-002-1 (proactive battery replacement). Aftermarket fix: Ohmmu lithium 12V battery. Replacement cost $150-500.
Symptoms: Vehicle won't start after parking overnight, 12V dead despite full main battery, low voltage warning
Early owner reports show modest single-digit percentage degradation after 60,000-80,000 miles — unremarkable for a young vehicle. Samsung 2170 cells in the Max pack (149 kWh). Full pack replacement is extremely expensive and rarely needed. Routine charging to 80-90% extends longevity. No widespread battery pack failures documented.
Symptoms: Gradually decreasing displayed maximum range, reduced charge rate at high or low state of charge
Vehicle Weaknesses 10
Well-documented issue emerging around 60,000 miles, frequently just after warranty expiry. Rivian service centers have acknowledged it as a 'common issue'. Out-of-warranty repair cost: $3,500-7,500. Air bags, compressor, or valve block may be involved. No broad service campaign — individual repairs only.
NHTSA Recall 22V-744 (October 2022) affects 2022 R1T and R1S. Nut connecting upper control arm to steering knuckle may not have been properly torqued. Can cause excess wheel camber or separation — increased crash risk. Rivian inspects and torques to spec at no charge.
Rivian recalled 19,641 vehicles (R1T + R1S, 2022-2025). Root cause: during suspension repairs before March 2025, the rear toe link joint could have been reassembled incorrectly. Separation causes loss of rear wheel control. One injury documented. Rivian replaces toe link bolts at no cost.
Clogged HVAC condensate drain plug routes water into the driver and passenger footwells instead of outside. Especially documented on Gen1 R1T. Service campaign RCA-26-24-002-1 replaces the drain plug proactively. If unaddressed: mold, odor, and in severe cases complete vehicle brick from electrical water damage. Rivian replaces carpet and HVAC assembly if needed.
NHTSA Recall 23V-883 affects 7,873 R1T and R1S vehicles (built June 2021 – October 2022). At high cabin temperatures, the pedal sensor failed to detect full release — Auto-Hold/Park did not activate and the vehicle crept forward. Rivian pre-patched 85% of affected vehicles via OTA before NHTSA issued the recall. Physical pedal replacement also provided at no cost.
The original powered tonneau cover on Launch Edition and early trucks was prone to jamming. A single motor drove the full width of the cover — when binding occurred, drive gears and rails were damaged. Rivian developed V1.5 then V2 with a smaller roll-up mechanism. Affected vehicles received replacement covers under warranty. Out-of-warranty cost: $300-2,500.
The most widely reported mechanical complaint on Gen1 trucks. Clunking or clicking on initial acceleration, during turns, or transitioning from acceleration to regeneration. Primarily affects 2022-2023 builds. Rivian has revised parts; warranty repairs are standard. Out-of-warranty: $400-1,800 depending on the affected component (halfshaft, hub, subframe).
Well-known issue on early deliveries 2021-2023. Panel gaps at hood, fenders, bed, and doors sometimes dramatically outside acceptable tolerances. Service centers have adjusted panels. Improved manufacturing quality from 2023 onward. No safety risk but unacceptable for a vehicle in this price range.
Retaining clip on the actuator slips off, throwing the port door out of alignment. Sometimes the door opens only halfway or won't close flush. DIY fix is possible (reseat clip, 3 screws). Service center repair covered under warranty. Out-of-warranty: $150-600 depending on the part.
Frequent owner reports of frozen touchscreens, OTA updates that fail multiple times, navigation outages, and HVAC controls disabled after updates. Consumer Reports cites software as one of the primary drivers of below-average reliability scores. Most bugs are resolved via OTA but the gap between problem and fix can stretch weeks.
