Used Toyota 4Runner 6th Gen (2025-2026): Buyer's Guide

The Toyota 4Runner went 15 years without a full redesign. Then, for 2025, Toyota dropped the naturally aspirated 4.0-liter V6 and ancient 5-speed automatic entirely, replacing them with a turbocharged four-cylinder, an 8-speed automatic, and an optional hybrid system borrowed from the same family as the Tacoma and Tundra. Owners noticed fast. On 4Runner6G.com, a forum built specifically for this generation, multiple independent threads describe a transmission that hunts for gears at low speed and shudders under light throttle at highway cruise. There's no recall for it. No TSB either. Just a brand-new platform still working out its kinks, and a used market that's about to fill up with early copies of it.

This Generation at a Glance

The 6th generation 4Runner (2025-present) rides on Toyota's TNGA-F body-on-frame platform, the same architecture underneath the current Tacoma, Tundra, Sequoia, and Land Cruiser. It's an all-new truck under the familiar boxy shape: double-wishbone front suspension, multi-link coil rear, a 112.2-inch wheelbase, a 14-inch touchscreen with standard Apple CarPlay and Android Auto, and Toyota's Proactive Driving Assist added for the first time on this nameplate. Seating configurations run five or seven passengers depending on trim, an option the outgoing 5th gen only offered in limited form. The 2026 model year is largely a carryover, with sound dampening added to the hood and engine bay, filler added to interior door panels to quiet rattles, and the front stabilizer disconnect mechanism (previously exclusive to TRD Pro and Trailhunter) now optional on the TRD Off-Road Premium hybrid.

Every review and owner thread agrees on one thing: this is a genuinely different truck from the 5th gen, not a facelift. The old 4.0-liter V6 and 5-speed automatic are gone entirely, replaced across the board by the turbocharged four-cylinder and 8-speed automatic. That's the tradeoff at the center of this whole guide. More power, more torque, better towing, and a transmission still working through early-production growing pains that the old, decade-tested 5-speed never had.

Powertrain & Trim Breakdown

2.4L Turbo i-FORCE (standard on most trims)

This is the base engine across SR5, TRD Sport, TRD Sport Premium, TRD Off-Road, TRD Off-Road Premium, and Limited. It makes 278 hp and 317 lb-ft, a modest bump over the old 4.0-liter V6's 270 hp but with far more torque available lower in the rev range, paired to a new 8-speed automatic replacing the previous 5-speed. Owners generally praise the added power and highway passing performance compared to the outgoing V6.

The complaint that keeps surfacing, across separate threads on 4Runner6G.com titled "Transmission Slip," "2026 TRD Pro possible transmission issue," and "Transmission sticking in 6th gear," is inconsistent low-speed shifting. Described symptoms include a hard clunk when a missed gear finally catches, hesitation shifting from 1st to 2nd on a cold engine, and gear hunting or a clutch-riding feeling accelerating from a stop. At least one owner reported the behavior mostly went away after roughly 200 miles of break-in; others still notice gear hunting during engine braking and downshifts well past that point. As of this writing, Toyota has not issued a TSB or recall addressing it, and forum posters have specifically flagged Toyota's silence on the subject.

The turbo four tows up to 5,000 lbs, a real number to know if you're cross-shopping against the old V6's roughly similar rating. Where the turbo four actually loses to the outgoing V6, in the eyes of some owners, is character. Toyota traded a naturally aspirated engine with a distinct, familiar sound for a smaller-displacement turbo four that several reviewers and forum posters describe as less charismatic, even with more power on paper. That's a subjective complaint, not a mechanical one, but it shows up often enough in owner threads to be worth knowing before you test drive one expecting the old V6 feel.

2.4L Turbo Hybrid i-FORCE MAX (standard on Platinum, TRD Pro, Trailhunter; optional on TRD Off-Road Premium and Limited)

The hybrid pairs the same 2.4-liter turbo four with a 48-hp electric motor built into the transmission, fed by a 1.87-kWh battery, for 326 hp and 465 lb-ft combined. The Trailhunter's tune dips slightly to 323 hp, likely a byproduct of its underhood skid plating restricting airflow. That torque figure is nearly 70% more than the old naturally aspirated V6 ever produced, and it shows in towing and passing response.

The tradeoff owners report most is a raised cargo floor. The hybrid battery pack sits under the rear cargo area, lifting the floor by 1-2 inches and cutting roughly 6 inches of vertical cargo height compared to non-hybrid trims. If you haul gear regularly, sit in a 4Runner with the hybrid battery before you buy one.

On the mechanical side, a separate 4Runner6G.com thread titled "Hybrid Drivetrain / Transmission Vibration" describes a shudder or vibration cruising at 50+ mph under light acceleration in a high gear, with Sport mode (which holds lower gears longer) suggested as a workaround by other owners in the thread. This appears to be the same underlying transmission-tuning complaint as the non-hybrid, not a separate hybrid-specific defect.

The hybrid also tows more: 6,000 lbs versus the turbo four's 5,000 lbs, a 1,000-pound gap that matters if you're pulling a travel trailer or a loaded car hauler. Toyota backs the hybrid components for 8 years or 100,000 miles and the hybrid battery specifically for 10 years or 150,000 miles, separate from the standard 3-year/36,000-mile basic warranty and 5-year/60,000-mile powertrain warranty that cover both engines. Given this generation's age, most used examples on the market today are still well inside every layer of that coverage.

Fit, finish, and what owners actually complain about day to day

Beyond the transmission, the recurring theme in owner reviews is a gap between Toyota's reputation for build quality and what buyers found at this price point. Interior material quality has drawn criticism relative to rivals like the Kia Telluride and Mazda CX-90, both of which start cheaper. Specific complaints include hard plastics throughout, mismatched textures and finishes, and even a fake rivet detail molded into the volume knob that reviewers called out as an odd design choice on a $50,000-plus vehicle. Separately, some TRD Off-Road, TRD Pro, and Trailhunter buyers who installed aftermarket rock sliders found the factory mounting holes weren't threaded, a quality-control miss that required a trip back to the dealer or a tap-and-die kit to fix.

None of this is a mechanical defect. It's the kind of fit-and-finish complaint that shows up in the first year or two of any redesigned platform, and it's worth walking into a used 6th gen 4Runner purchase expecting hard plastics and the occasional rattle rather than the last-generation truck's more settled interior. On the positive side, owners consistently praise the power increase over the old V6, the ride quality improvement from the new suspension geometry, the 14-inch touchscreen and 360-degree camera system, and the dealer buying experience, though that last point comes with an asterisk: this generation launched into serious supply constraints, and dealer markups of $5,000 to $8,000 over MSRP were common in the first year, with some TRD Sport and TRD Off-Road listings marked up as much as $18,000. If you're shopping used, ask whether the original buyer paid a market adjustment. It won't show up on a title, but it's relevant to what the truck is actually worth today.

One clarification worth making directly: this is not the same engine architecture involved in the 2022-2023 Toyota Tundra and Lexus LX 600 engine recall. That recall covered a 3.4-liter twin-turbo V6 with machining debris left in the block during production. The 4Runner's i-FORCE and i-FORCE MAX engines are a 2.4-liter turbocharged inline-four, a different displacement and cylinder count built on a separate line. CarScout's NHTSA-sourced recall data shows nothing filed against the 4Runner's engine as of this guide.

Recalls on record

CarScout's NHTSA-sourced data shows zero recalls for the 2025 model year. The 2026 model year has one: campaign 26V282000, filed by Gulf States Toyota (a regional distributor, not Toyota Motor Corporation directly) for an incorrect load-carrying-capacity label on certain 2026 4Runners. It's a paperwork fix, a corrected label mailed to owners free of charge, not a mechanical repair. Owner notification letters went out June 18, 2026.

Trim Levels

The single most important line in that table: an electronic locking rear differential and Crawl Control are standard on TRD Off-Road, TRD Off-Road Premium, TRD Pro, and Trailhunter, and absent on SR5 and both TRD Sport trims. TRD Sport looks the part with its blacked-out styling and sport suspension, but it can't lock the rear axle or crawl a technical trail the way the TRD Off-Road can. If off-road capability is the reason you want a 4Runner, TRD Off-Road is the actual starting point, not TRD Sport.

TRD Pro and Trailhunter both start around $67,000 and share the same hybrid powertrain, but they're built for opposite jobs. TRD Pro's Fox shocks and hood scoop are tuned for speed over rough terrain, desert running and fast washboard roads. Trailhunter's Old Man Emu shocks and ARB-branded steel rack and rock rails are tuned for slow, deliberate overlanding, the kind of trip where you're actually carrying a rooftop tent or jerry cans on that rack.

Which Model Years to Target Within This Gen

This is a two-model-year generation as of this guide, so there isn't a multi-year track record to lean on yet. Both years share the same reported transmission behavior; 2026 buyers get quieter cabin refinements but no documented mechanical change to the transmission tuning. Neither year has a track record long enough to call one clearly safer than the other. Treat both the same way: verify the specific car, not just the model year.

Pre-Purchase Inspection Checklist

This generation is too new for mileage-based failure patterns. There's no 80,000-mile water pump or 120,000-mile transmission rebuild data yet, because these trucks haven't been on the road long enough to generate it. What you're checking for instead is whether this specific truck exhibits the early-ownership issues other 6th gen owners have already reported.

• Drive it cold. From a stop, in 1st to 2nd gear, feel for hesitation or a hard clunk as the transmission catches. This is the exact complaint pattern from multiple 4Runner6G.com threads.
• Get it up to highway speed and hold a light, steady throttle in a high gear. A shudder or vibration around 50+ mph under light acceleration matches the reported hybrid drivetrain complaint. Switching to Sport mode and seeing if the vibration disappears is a useful diagnostic, not a fix.
• On TRD Off-Road, TRD Pro, or Trailhunter trims with aftermarket rock sliders installed, ask the seller whether the factory mounting holes needed to be re-tapped. Owners have reported unthreaded holes from the factory on these mounting points.
• If it's a 2026 model, ask whether the load-carrying-capacity label recall (campaign 26V282000) was completed. It's a low-stakes fix, a new label, but a seller who can answer confirms the car's paperwork is in order.
• If you're cross-shopping hybrid vs. non-hybrid, physically check cargo height with the rear seats folded before you decide. The hybrid's raised floor is a real, permanent tradeoff, not a spec sheet footnote.
• Confirm the trim actually has the off-road hardware you're paying for. TRD Sport and TRD Sport Premium do not include a locking rear differential or Crawl Control; TRD Off-Road and above do.
• Ask for remaining ToyotaCare balance (2 years/25,000 miles from the original in-service date) and confirm the basic 3-year/36,000-mile and powertrain 5-year/60,000-mile warranties are still active and transfer with private-party sales, which Toyota's warranty generally does.
• Ask whether the original buyer paid a market adjustment over MSRP. It doesn't affect the mechanicals, but it affects what a fair resale price actually is on a truck this fresh to the used market.

Run the VIN through a recall check regardless of what the seller tells you.

Running Costs

Both engines run on regular gasoline, a change from nothing in particular since the old V6 also ran regular, but worth confirming since several rivals in this class now recommend premium. Toyota's hybrid systems have a long track record of reliability in the Prius, RAV4, and Highlander, but this specific 2.4-liter i-FORCE MAX application is new enough that there's no multi-year ownership data to draw on. Budget for standard maintenance at Toyota-recommended intervals and don't assume this hybrid will behave exactly like older, more established Toyota hybrid systems.

Warranty coverage is where buying used actually works in your favor on this generation. Toyota's basic warranty runs 3 years or 36,000 miles, powertrain coverage runs 5 years or 60,000 miles, and hybrid-specific coverage extends further: 8 years or 100,000 miles on hybrid components, 10 years or 150,000 miles on the hybrid battery itself. Because this is only a 2025-2026 generation, almost every used example currently on the market is still inside the basic warranty window and well inside the powertrain and hybrid coverage. New buyers also got ToyotaCare, two years or 25,000 miles of complimentary scheduled maintenance plus two years of roadside assistance. If you're buying a low-mileage used 4Runner from this generation, check how much of that ToyotaCare window the previous owner has already used. A truck still under it effectively comes with free oil changes built in.

FAQ

Is the 2025-2026 Toyota 4Runner reliable? It's too early to say with mileage-based data. What's documented so far is early-ownership feedback: reports of transmission gear-hunting and hesitation on forums like 4Runner6G.com, with no official recall or TSB addressing it yet. Toyota's underlying reliability reputation is strong, but this specific platform is unproven long-term.

Should I get the turbo four-cylinder or the i-FORCE MAX hybrid 4Runner? The hybrid adds 48 hp, 148 lb-ft of torque, and better low-end response for towing, but raises the cargo floor by 1-2 inches and cuts about 6 inches of vertical cargo height. Choose the hybrid for towing and power, the turbo four if cargo space matters more.

What's the difference between the 4Runner TRD Pro and Trailhunter? Both use the same 326-hp hybrid powertrain (323 hp on Trailhunter) and start around $67,000. TRD Pro runs Fox shocks tuned for high-speed off-road driving. Trailhunter runs Old Man Emu shocks and an ARB roof rack and rock rails tuned for slow, technical overlanding with gear.

Does the new 4Runner have transmission problems? Owners on dedicated 6th gen forums report gear hunting, hesitation from a cold start, and shuddering at highway cruise under light throttle. No recall or TSB has been issued for it as of this guide. It's a documented early-ownership pattern, not a confirmed defect with a known fix.

Is the turbo four-cylinder 4Runner as reliable as the old V6? There's no way to know yet. The old 4.0-liter V6 earned its reputation over 15 years on the road. The new turbo four and hybrid i-FORCE MAX have been in 4Runners for about a year and a half as of this guide, not long enough to compare.

Bottom Line

If you want a 6th gen 4Runner with real off-road hardware, TRD Off-Road is the floor, not TRD Sport. If towing or low-end power matters more than cargo height, the hybrid earns its price premium; if you haul gear, the turbo four keeps your cargo floor lower. Before you buy, cold-start the transmission and hold a light throttle at highway speed, the two conditions where owners report the most inconsistent shifting. Run every VIN through a recall check regardless of what the seller says. Early copies of a hot, markup-heavy redesign are exactly the kind of listing that's hard to track manually across every dealer site; CarScout checks the market daily and emails you when a 4Runner in your trim, price, and mileage range shows up.
