Top 10 Recalls, Advisories, Safety Alerts, and TSB Highlights
👉 Tip: Below is a mixed list of notable recalls plus manufacturer communications/programs that frequently intersect with real-world ownership. Confirm eligibility by VIN (recall status can differ by region and distributor).
1. Floor Mat Recall (2009)
Potential for unsecured or incompatible floor mats to interfere with accelerator pedal. Part of Toyota’s major unintended acceleration recall campaign affecting millions of vehicles
2. Spare Tire Carrier Recall (2013)
Spare tire carrier assembly may corrode and separate, causing the spare tire to detach from the vehicle while driving.
3. Frame Rust Recall (Ongoing inspections)
Vehicles sold or registered in cold-weather states may experience excessive frame rust. Toyota has inspected and replaced frames on affected vehicles under extended warranty programs.
4. Secondary Air Injection System
TSB Check engine light related to secondary air injection pump and valve failures. Common issue requiring replacement of pump assembly ($800-1,500 repair).
5. Lower Ball Joint TSB
Premature wear of lower ball joints causing clunking noises and handling issues. Inspection and replacement recommended every 30-40k miles in severe conditions.
6. Airbag Inflator Recall (Takata – 2016) Defective Takata airbag inflators that could rupture and spray metal fragments. Multiple recall campaigns; check if your VIN has been remedied.
7. Brake Master Cylinder TSB Reports of spongy brake pedal feel due to master cylinder seal degradation. TSB provides inspection and replacement procedures.
8. Transfer Case Actuator TSB 4WD models may experience difficulty engaging or disengaging 4WD modes due to transfer case actuator motor failure.
9. Steering Intermediate Shaft TSB Clicking or clunking noise from steering column during turning. Resolution involves lubricating or replacing intermediate shaft.
10. Rear Differential Seal Leak TSB Rear differential pinion seal may leak fluid. More common on vehicles with higher mileage or those used for towing.
11- Accessory seat heater wiring can be damaged (SET campaign) — risk of overheating in certain dealer-installed accessory heaters.
12- Accessory seat heater wiring (earlier SET action) — similar condition, earlier notice for certain distributor-installed accessories.
13- Safety Recall 90L (Phase 10): floor mat interference with accelerator pedal — accelerator pedal can stick if trapped by unsecured/incompatible mat.
14- Non-compliance recall 10V-036 (labeling) — missing load-carrying capacity modification labels (Southeast Toyota).
15- Non-compliance recall 10V-035 (labeling) — missing load-carrying capacity modification labels (Gulf States Toyota).
16- Warranty Enhancement Program ZG7: rear hatch glass can break during defroster operation — program terms/eligibility apply.
17- TSB: Air Injection System MIL “ON” (2UZ-FE applications) — addresses common air injection MIL conditions that owners frequently encounter.
18- TSB/communication: front differential cyclical groan/grind noise — described condition on the shared drivetrain platform.
19- Advisory reminder: check recalls by VIN regularly — NHTSA recommends periodic checks because VINs can be added over time.
20- Owner best practice: verify campaigns via Toyota Owners / Toyota recall lookup portals (US/CA differ) before paying out-of-pocket.
🔔 Important Note: Always run a VIN-specific check through NHTSA (nhtsa.gov/recalls) or Toyota’s recall website to verify which recalls apply to any specific vehicle you’re considering, and confirm all recall work has been completed.
👉 Note : The 2007 4Runner uses different engines and calibrations by trim and market. Use these tables as a quick reference list (examples), then confirm exact definitions and diagnostic flowcharts in the OEM manual for your VIN.

Frequently Asked Questions
What engines are available? The 2007 4Runner offers two engines: a 4.0L V6 (236 hp, 266 lb-ft torque) standard on most trims, and a 4.7L V8 (260 hp, 306 lb-ft torque) available on Limited and standard on Sport Edition.
What’s the fuel economy? The V6 gets around 16-17 mpg city / 20-21 mpg highway. The V8 drops to approximately 15 mpg city / 19 mpg highway. These are thirsty vehicles by modern standards.
Is it reliable? Generally yes. The 2007 4Runner has a strong reputation for reliability and longevity, typical of Toyota SUVs from this era. Many owners report vehicles exceeding 200,000+ miles with proper maintenance.
What are common problems to watch for? Secondary air injection system failures, lower ball joint wear, timing belt issues on V8 models (needs replacement every 90k miles), frame rust on vehicles from salt-belt states, and potential transmission issues.
Does it have 4WD or AWD? Available in both 2WD (RWD) and 4WD configurations. The 4WD system is part-time on most models, with full-time 4WD available on Limited trims. Many feature a locking rear differential and low-range gearing.
How much can it tow? The V6 can tow up to 5,000 lbs, while the V8 increases capacity to 7,300 lbs when properly equipped.
What trim levels were offered? SR5, Sport Edition, Limited, and a special Urban Runner package. The Sport Edition featured the V8, unique suspension, and distinctive styling.
How’s the interior space? Seating for 5 or 7 (optional third row on SR5 and Limited). The third row is cramped and best suited for children. Cargo space is 46.3 cubic feet behind the second row, or 8.9 cubic feet with third row up.
What should I budget for maintenance? Expect regular maintenance costs around $500-800 annually. Major services (timing belt on V8, transmission fluid, coolant flushes) can add $1,000-2,000 every few years. Parts are reasonably priced and widely available.
What’s a fair price today? Prices vary widely based on condition, mileage, and location, but typically range from $8,000-18,000. Low-mileage, well-maintained examples with 4WD command premium prices due to strong demand for this generation.
- Is the 2007 4Runner still a good buy today?
- Yes—if rust is under control and maintenance is documented. It’s one of the most proven body-on-frame SUVs, but the best ones are the ones that have had suspension/cooling and wear-items kept up.
- Which engine is better: V6 or V8?
- The V6 is usually cheaper to run and simpler for many owners. The V8 feels stronger for towing and load, and can be worth it if you actually use that capability. Power figures differ by engine.
- What should I check before buying?
- Frame rust, transfer case/4WD engagement, cooling leaks, brake caliper condition, suspension clunks, and scan for pending codes. Also verify recall/program eligibility by VIN.
- Any “must do” prevention?
- Keep fluids fresh, grease driveline if applicable, exercise 4WD monthly, and don’t ignore small coolant leaks. Small maintenance prevents big bills on older SUVs.
- Where can I get OEM-level wiring/repair info?
- OEM manuals are the fastest way to avoid guesswork. For this platform: 2007 4Runner wiring diagram and 2005–2009 4Runner repair manual
Top 5 Competitors (2007 Model Year)
- Jeep Grand Cherokee ↗ More car-like ride, available HEMI V8, better on-road manners but less reliable long-term.
- Nissan Pathfinder ↗ Similar size and capability, more powerful V6, but known for transmission issues in this generation.
- Ford Explorer ↗ More spacious third row, lower price point, but significantly less reliable and poorer resale value.
- Chevrolet TrailBlazer ↗ Competitive towing, available inline-6 or V8, but inferior reliability and fuel economy.
- Honda Pilot ↗ More refined, better fuel economy, superior third-row space, but less off-road capability and unibody construction vs. body-on-frame.
The 2007 4Runner earns its reputation the hard way: time, miles, and real-world abuse. If you want a modern-feeling crossover, this isn’t it. But if you want a durable SUV that can tow, travel rough roads, and stay in the family for another decade, a clean, rust-controlled 4Runner with proof of maintenance is still one of the smartest used buys—especially if you budget upfront for suspension refresh, brakes, and cooling system catch-up.
