The 2024 Toyota Tacoma launched with a manufacturing defect inside the 8-speed automatic transmission. Aisin, the transmission supplier, failed to clean casting debris from some torque converter housings before they shipped. That debris got into the transmission fluid, migrated to the shift solenoids, and destroyed them. Some owners had their transmissions replaced two and three times before Toyota traced the root cause. Toyota issued a service bulletin, T-SB-0094-24, not a recall. Which means it does not appear on the standard NHTSA recall lookup.
If you are shopping a used 2024 Tacoma with the automatic, the first thing you do is run the VIN through Toyota's service campaign portal. Before the test drive. Before the Carfax. The TSB check is that important on this generation.
That is the one hard rule. Everything else about this truck is genuinely impressive. The 4th gen is the most significant Tacoma redesign since 2005: new turbocharged engine, new multi-link coil rear suspension on most trims, a much better interior, and for the first time in Tacoma history, a factory hybrid powertrain producing 465 lb-ft of torque. The 3rd gen ran on the same basic platform for eight years. This one is a real departure.
This Generation at a Glance
The 4th gen Tacoma launched for the 2024 model year on Toyota's TNGA-F platform, the same architecture that underpins the Tundra. The 3.5L V6 from the 3rd gen is gone, replaced by the T24A-FTS 2.4-liter turbocharged four-cylinder in two states of tune, plus an optional i-Force Max hybrid variant. The leaf-spring rear suspension is gone on most trims, replaced by a coil-link multi-link setup that changed the ride character substantially.
The generation received minor updates for 2025 (auxiliary switch amperage increased from 30 to 95 amps, new Mudbath color) and 2026 (Heritage Blue and Wave Maker colors added, black front logos on TRD trims, Adaptive Variable Suspension standard on all Limited models). No major mechanical changes between years. No mid-cycle refresh planned as of mid-2026.
One structural difference within the generation that matters for used buyers: rear suspension configuration splits by cab and trim. The SR and SR5 XtraCab use leaf-spring rear suspension. The SR5 Double Cab and every trim above it use coil-link. This is not a defect. It is spec. It dramatically affects ride quality.

Powertrain and Trim Breakdown
2.4L Turbo, Low Output (228hp, SR Only)
The SR gets a detuned T24A-FTS producing 228 horsepower and 243 lb-ft. That is less output than the 3rd gen V6, in a heavier truck. Owners who test a higher-trim 4th gen before landing on an SR report the difference immediately.
Two things make the SR worth knowing about. First, the 6-speed manual is available only on SR and SR5. A used SR with the manual makes 270 horsepower, not 228, and is not affected by T-SB-0094-24, which covers only the 8-speed automatic. Second, the SR uses leaf springs in the rear regardless of cab or bed configuration. The choppy unladen ride on a rough road is not a worn suspension. That is how leaf springs behave on an empty truck.
No documented powertrain failures specific to the 228hp engine tune. On automatic SR trucks, the T-SB-0094-24 check still applies.
2.4L Turbo, High Output (278hp, SR5 and Above)
The 278hp / 317 lb-ft version is in the overwhelming majority of 4th gen Tacomas on the used market. This is the engine owners are talking about when they say the 4th gen finally drives like a modern truck.
What owners like: The 2.4T delivers peak torque lower in the RPM band than the old V6, making it feel consistently responsive in traffic, at passing speeds, and in technical driving situations. TacomaWorld and Tacoma4G forum members consistently describe the 8AT and 2.4T as well-matched, an improvement they did not expect. The truck is also noticeably quieter than the 3rd gen at highway speed.
The T-SB-0094-24 transmission issue: During manufacturing, Aisin failed to clean casting debris from torque converter housings at the factory. That debris got picked up by transmission fluid, migrated into the transmission, and damaged the shift solenoids. Symptoms owners reported include harsh or erratic shifts from 1st to 2nd, hesitation from a stop, shuddering between 30 and 45 mph, and in severe cases, complete loss of drive. Toyota's remedy required replacing both the transmission assembly and the torque converter. Cases where only the transmission was swapped without the torque converter led to repeat failures in multiple documented instances on the forum.
Toyota issued T-SB-0094-24 on September 9, 2024. It covers specific 2024-model VINs produced before Aisin corrected the process. Whether a specific used truck is affected depends on its production date. The VIN check tool is at toyota.com/recall under "Service Campaigns." Standard recall lookups at NHTSA.gov will not surface this.
If the TSB shows as open on a used 2024 you are considering, the transmission has not been inspected or repaired. That truck may fail days or months after purchase. The powertrain warranty (5 years / 60,000 miles, transferable) covers the repair, but not the inconvenience.
Long-term engine consideration: The T24A-FTS is a turbocharged direct-injection engine without port injection. Carbon buildup on the intake valves accumulates over time, particularly in vehicles driven mostly in city traffic with frequent cold starts. This is common to all turbocharged GDI engines and not unique to Toyota. Walnut blasting or intake cleaning typically runs $200-$400. Owners and forum consensus suggest budgeting for this around 60,000-80,000 miles.
i-Force Max Hybrid (326hp / 465 lb-ft)
The i-Force Max pairs the 2.4T engine with an electric front-axle motor generator, producing 326 horsepower and 465 lb-ft of torque, the highest output in Tacoma history. Standard on TRD Pro and Trailhunter. Optional on TRD Off-Road via the i-Force Max Premium Package.
The torque is the point. The electric motor delivers its output instantly, before the turbocharger builds boost pressure. Off-road owners and regular towers describe this as fundamentally different from any previous Tacoma. In rock crawling, technical descents, and passing maneuvers, the immediate torque response is a real capability advantage over the standard 2.4T.
The fuel economy improvement is modest. EPA estimates 23-24 MPG combined for the i-Force Max versus 21-23 for the non-hybrid 278hp automatic. Real-world highway numbers run around 20 MPG at 70 mph per owner data tracked on Fuelly. The hybrid does not make a compelling case on fuel savings alone. It makes its case on torque.
The T-SB-0094-24 issue applies to all 2024 i-Force Max models. Toyota expanded the TSB in October 2024 to explicitly include hybrid trucks after initial reports came in. The remedy on hybrid models includes replacing the hybrid module in addition to the transmission and torque converter. The check procedure is identical: run the 2024 VIN through toyota.com/recall under Service Campaigns before purchase.
No documented failures of the hybrid battery or motor generator have emerged from roughly two years of real-world data. The high-voltage battery carries a federal minimum warranty of 10 years / 150,000 miles. Any used buyer has meaningful coverage remaining. Verify this against the original sale date, not the current odometer.
Trim-Specific Notes
SR is the least-value 4th gen configuration for daily driving. Leaf springs and the 228hp tune make it noticeably inferior to every other trim. Used SR pricing rarely reflects that capability gap adequately.
SR5 Double Cab is the value floor. Coil-link rear suspension, 278hp engine, wireless Apple CarPlay, and a functional interior at the most accessible price point. The leap from SR XtraCab to SR5 Double Cab costs $5,000-$8,000 on the used market. It is worth it.
TRD Sport targets the pavement buyer who wants styling and coil springs without paying for off-road hardware. Bilstein shocks are not included. The TRD Sport is not a trail truck.
TRD Off-Road hits the sweet spot for buyers who actually use the truck off-road. Bilstein monotube shocks with remote reservoirs, electronically locking rear differential, Crawl Control low-speed cruise, Multi-Terrain Select, composite skid plates, and all-terrain tires as standard equipment. The capability gap between TRD Off-Road and TRD Pro is real but smaller than the price gap, which runs $15,000-$20,000 on the used market. For anyone short of dedicated high-speed trail running, the TRD Off-Road handles everything the TRD Pro handles more cheaply.
Limited adds Adaptive Variable Suspension (standard on 2026 models, optional on 2024-2025), the 14-inch touchscreen as standard, power tailgate with extending running boards, and SofTex interior trim. The AVS noticeably improves on-road ride quality on 2026 models. If you want a comfortable daily driver with truck capability and no need for heavy off-road equipment, the Limited is well-configured.
TRD Pro starts at $63,900 new. Used examples price above $50,000 in the first two years. Fox QS3 internal-bypass shocks, standard i-Force Max, 18-inch black wheels, 1-inch front lift, ARB aluminum front bumper, and the exclusive IsoDynamic Performance Seats with built-in dampers to stabilize the driver's field of view on rough terrain. Built for fast off-road use. Significant overkill for daily driving.
Trailhunter starts at $62,900 new and targets overlanders rather than speed runners. Old Man Emu forged monotube position-sensitive shocks with piggyback reservoirs instead of Fox, hot-stamped steel skid plates instead of TRD Pro's aluminum front plate, and a standard ARB sport bar with Molle panels in the bed. Standard i-Force Max. Better ground protection than TRD Pro for slow technical terrain. Worse for high-speed desert trails. Double Cab only.
Which Model Years to Target Within This Gen
| Year | Recalls | Complaints | Key Notes | Verdict |
|---|---|---|---|---|
| 2024 | 1 (brake hose) | 134 | Transmission TSB on early-production 8ATs | Caution: verify TSB-0094-24 |
| 2025 | 3 (brake hose, instrument panel, driveshaft) | 50 | TSB not a concern, 3 addressable recalls | Good: check all recalls by VIN |
| 2026 | 0 | 4 | Minor updates, cleanest record so far | Best: but priced near-new |
2024: The transmission TSB is the primary concern. NHTSA recorded 134 complaints in the first year, with 41 in the powertrain category and 32 involving injuries. That complaint count is elevated compared to a typical first-year truck launch. It corresponds directly to the TSB period. For 2024 trucks with confirmed TSB completion and service documentation, the truck is in good shape. The powertrain warranty runs 5 years / 60,000 miles and is transferable to second owners. Any remaining exposure to a late-developing TSB is covered.
2025: Three recalls, but all are specific and verifiable. The brake hose recall (25V058) covers approximately 222,000 vehicles across 2024-2025 production. The front driveshaft recall (25V656000) covers approximately 6,000 four-wheel-drive 2025 models, a small slice of total production. The instrument panel software recall addresses a display issue at startup. Total NHTSA complaints dropped to 50 for 2025, substantially fewer than 2024. Production-line quality was clearly more consistent.
2026: Zero NHTSA recalls filed and only four complaints recorded as of mid-2026. The generation's most reliable year on paper. The trade-off is that used 2026 inventory is predominantly trucks sold by early buyers at near-MSRP pricing, with minimal mileage but minimal depreciation savings too.
Best target: A mid-to-late 2025 TRD Off-Road, automatic, with all three recalls confirmed as completed.
Pre-Purchase Inspection Checklist
For any 2024 Tacoma with 8-speed automatic (standard or i-Force Max):
- Before the test drive, go to toyota.com/recall and enter the VIN under "Service Campaigns." If T-SB-0094-24 shows as open, this truck's transmission has not been addressed. Walk away or get a firm written commitment that the dealer will complete it before delivery.
- Start the truck cold and drive immediately. Any hesitation pulling into traffic, hard shift from 1st to 2nd, or vibration between 30 and 45 mph is a symptom of debris damage to the shift solenoids. This behavior does not always disappear at operating temperature.
- Ask for dealership service records showing T-SB-0094-24 work or a transmission replacement. A private seller who cannot produce records for a 2024 automatic should prompt a dealer VIN lookup before you go further.
For 2025 four-wheel-drive models:
- Verify front driveshaft recall (25V656000) completion. The defect is a CV joint ball cage made from incorrect material that can deform or break. Dealer replaces both front driveshaft assemblies free. This recall affects a small fraction of 2025 4WD trucks but the failure mode is serious enough to check explicitly.
For all 2024-2025 four-wheel-drive models:
- Confirm rear brake hose recall (25V058) was completed. Mud and dirt packing inside the rear wheels can wear through the brake hoses and cause fluid leakage. Any truck with visible off-road use and mud caking deserves a closer look at the rear hoses regardless of recall status.
Instrument cluster check on any 2024-2025:
- Turn the ignition to accessory position without starting. The instrument cluster should light up fully, including the speedometer display, brake system warning, and TPMS light. Partial illumination at startup is the instrument panel software recall symptom. If it is not right, the software remedy has not been applied.
Suspension check:
- SR and SR5 XtraCab: leaf springs in the rear are standard and normal. A bouncy, choppy ride on rough pavement with an empty bed is expected behavior. It is not a worn suspension.
- SR5 Double Cab and above with coil-link: the rear end should feel controlled and composed. Excessive bounce or lateral wander on rough pavement suggests shock absorber wear. On high-mileage TRD Off-Road trucks used aggressively off-road, Bilstein shocks can wear faster than normal.
Off-road trim underbody check:
- TRD Off-Road, TRD Pro, Trailhunter: skid plates hide damage below them. Lift the truck and inspect the frame rails, transfer case skid, and differential guards directly. TRD Pro uses aluminum front skid; Trailhunter uses steel throughout. Both are thick but not invincible.
- Check the rear departure angle area on any truck with bed cargo markings or roof rack mounts. These trucks were used.
Infotainment:
- Test both wireless CarPlay and Android Auto pairing. Swipe through all zones of the touchscreen. Dead zones at the upper corners have been reported on early units of both the 8-inch and 14-inch screens.
Running Costs
| Powertrain | Combined MPG | Key Maintenance | Est. Annual Fuel Cost |
|---|---|---|---|
| 2.4T 228hp (8AT) | 20-22 | 0W-20 synthetic, 5.9 qt, 10k interval | ~$2,900-3,200 |
| 2.4T 278hp (8AT) | 21-23 | 0W-20 synthetic, 5.9 qt, 10k interval | ~$2,700-3,000 |
| 2.4T 270hp (6MT) | 20 | 0W-20 synthetic, 5.9 qt, 5-7.5k interval | ~$2,900+ |
| i-Force Max (8AT) | 23-24 | 0W-20 synthetic, 5.9 qt, 10k interval | ~$2,600-2,800 |
Toyota specifies 0W-20 full synthetic for all T24A-FTS variants. Engine oil capacity is 5.9 quarts including the filter. Official Toyota interval is 10,000 miles or 12 months under normal driving conditions. That drops to 5,000 miles for dusty roads, gravel, or off-road use. Many owners on Tacoma forums run 5,000-mile intervals regardless, citing standard practice for any turbocharged engine. Both positions are defensible.
Oil change cost at a dealership runs $60-100. Toyota Care covers the first 2 years / 25,000 miles of scheduled maintenance for new vehicle purchases. On a used purchase, check the remaining balance.
Transmission fluid: not on Toyota's standard maintenance schedule for the 8AT, but forum consensus suggests a fluid change at 60,000 miles for any truck used for towing or frequent off-road driving. Dealership cost is $150-$250.
At 60,000-80,000 miles, budget $200-$400 for intake valve carbon cleaning on any 8AT-equipped 4th gen. This is routine for turbocharged direct-injection engines without port injection, not a manufacturing defect.
i-Force Max high-voltage battery replacement: no 4th gen replacements have been documented yet. On other Toyota hybrid platforms, out-of-warranty replacements run $3,000-$8,000. The federal warranty minimum of 10 years / 150,000 miles covers most used buyers for the foreseeable future.
FAQ Block
Is the 4th gen Toyota Tacoma 2.4L turbo engine reliable? The T24A-FTS engine itself has not shown major failures in two-plus years of real-world ownership. The transmission issue documented in 2024 production was a supplier manufacturing defect in the torque converter, not an engine design flaw. The engine is also used in the Land Cruiser and other high-volume Toyota applications designed for high mileage.
What year 4th gen Tacoma should I avoid? Early-production 2024 automatics carry the most risk due to T-SB-0094-24. The defect is repairable under warranty, but requires active VIN verification to rule out. 2025 and 2026 models are not affected by the transmission TSB. No year should be categorically avoided if the appropriate recall and TSB checks pass.
Should I get the i-Force Max or the standard 2.4T? The i-Force Max delivers 465 lb-ft versus 317 lb-ft on the standard high-output tune. The electric motor fills in torque instantly before the turbo spools, which matters most in off-road crawling and towing. For daily commuting, the 278hp standard tune is adequate. The fuel economy improvement is roughly 2-3 MPG combined, not a strong standalone justification for the premium.
Is the TRD Off-Road worth paying over the SR5 Double Cab? For buyers who use the truck off-road at all, yes. Bilstein remote reservoir shocks, electronically locking rear differential, Crawl Control, and all-terrain tires add real capability. On the used market, the gap between SR5 Double Cab and TRD Off-Road runs $4,000-$7,000. That premium buys hardware that cannot be easily replicated with aftermarket parts for the same money.
How many miles does a 4th gen Tacoma last? No long-term data above 150,000 miles exists for the 4th gen yet. The 3rd gen routinely cleared 300,000 miles with regular maintenance on the 3.5L V6. The T24A-FTS is a newer turbocharged design and long-term longevity is unproven. Toyota's chief engineer confirmed the turbocharger is commercial truck grade, rated for 50% more duty cycles than passenger car turbos.
Bottom Line
The 2025 TRD Off-Road with the 8-speed automatic is the target. Past the transmission TSB window, all recalls verifiable by VIN, coil-link suspension, Bilstein shocks and e-locker standard, and a truck that is measurably better than anything the 3rd gen offered at the same price point.
On any 2024 automatic, check T-SB-0094-24 status first. That lookup takes two minutes and eliminates the most significant financial risk in buying this generation. Run every VIN through a recall check for the remaining open campaigns.
