4RunnerSUV
4.0L V6 · SUV
The 2014 Toyota 4Runner is a fifth-generation body-on-frame SUV that has earned a loyal following for its rugged durability and off-road capability — in a segment that has mostly migrated to car-based crossovers. Powered by a 4.0L V6 and backed by Toyota's time-tested 4WD system, it's built to handle Wisconsin winters, forest roads, and boat-launch ramps without complaint. Inside, the 4Runner is deliberately old-school: upright seating, a tall ride height, and a real transfer case. It's not the most fuel-efficient or the most refined highway cruiser, but owners routinely rack up 200,000–300,000 miles with nothing more than routine maintenance. The 2014 model sits in the sweet spot of the fifth generation — the major first-year bugs of 2010 were already sorted. For Lake Geneva-area owners this truck is a strong choice: the part-time 4WD with low range handles deep snow and icy hills, ground clearance keeps the underside away from packed snow, and the proven drivetrain doesn't leave you stranded in the cold.

Known for
- Exceptional long-term reliability and high-mileage durability
- Capable part-time 4WD with low-range transfer case
- Strong resale value — consistently near the top of its segment
- Simple, repairable drivetrain that independent shops can handle easily
Best for
- Owners who keep vehicles 10+ years and want low repair surprises
- Snow, off-road, and light trail use around Lake Geneva and beyond
- Towing boats, trailers, and campers up to 5,000 lbs
- Families needing three-row seating (SR5/Limited with third row)
Watch for
- Fuel economy is genuinely poor — budget for it
- Third-row seat is very tight; adults won't fit comfortably
- Older VVT-i oil control valve issues if oil changes are skipped
- Frame rust if the truck lived in a salt-belt state before you bought it

Maintenance schedule
- 1 Every 5,000 mi or 6 months — do not stretch to 10k Engine oil and filter change
The 1GR-FE VVT-i system is sensitive to oil cleanliness. Sludged oil is the #1 cause of expensive VVT and timing chain repairs on this engine. Use 0W-20 or 5W-20 full synthetic and change it on time, every time.
- 2 Every 30,000 mi or sooner after water crossings Transfer case, front differential, and rear differential fluid change
These fluids are routinely skipped but are critical to the 4WD drivetrain's longevity. Moisture and metal particles degrade the fluid; fresh fluid is cheap insurance against $1,500+ rebuilds.
- 3 Every 60,000 mi (iridium plugs) Spark plug replacement
The iridium plugs last 60k but misfires from worn plugs put stress on ignition coils, which are more expensive. Do plugs and inspect coils together.
- 4 Every 100,000 mi (Super Long Life Coolant), then every 50,000 mi after Coolant flush
Toyota SLLC is pink/red. Do not mix with green coolant. Degraded coolant corrodes the aluminum water pump and intake passages.
- 5 Every 2 years regardless of mileage Brake fluid flush
Brake fluid absorbs moisture over time. In Wisconsin winters, moisture-laden fluid lowers the boiling point and can cause ABS actuator corrosion from the inside. A $80 flush prevents a $1,000+ actuator replacement.
- 6 Every 60,000 mi or if humming noise develops Inspect and repack front wheel bearings / check rear axle seals
Water crossings and Wisconsin road spray work past worn seals. Catching a seeping rear axle seal early is a $50 fix; ignoring it contaminates the rear brakes and differential.
- 7 Every fall before salt season Undercarriage rust inspection and treatment
Lake Geneva roads are heavily salted November through March. Annual inspection of frame rails, control arm mounts, and skid plate brackets — plus a rust-inhibitor application — extends structural life significantly.
- 8 Every 15,000–20,000 mi (engine); every 15,000 mi or annually (cabin) Cabin and engine air filter replacement
The 4Runner's cabin filter is behind the glove box and often skipped. A clogged filter strains the blower motor and reduces defrost effectiveness — a real problem in Wisconsin winters.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
Cost of ownership
Annual maintenance
$400 – $900
Fuel
At 18 MPG combined and typical mixed driving (~12,000 mi/yr), expect $2,000–$2,600/year at current Wisconsin gas prices. Fill with regular 87 octane — premium is not required.
Insurance
Mid-size SUV rates; typically $900–$1,500/year depending on coverage, driver history, and ZIP. The 4Runner's high resale value means comprehensive/collision premiums run slightly above average for the segment.
The 4Runner has a low cost-of-ownership story once you accept the fuel bill. Routine maintenance is affordable at an independent shop, major failures are rare when oil changes are done on time, and resale value is strong enough that you recover more at trade-in or sale than most comparable trucks. Budget $400–$900/year for normal service intervals; add $200–$400 every 30k for drivetrain fluids if you use the 4WD system regularly.
Seasonal care
Lake Geneva, WI Winter
- Switch to a full synthetic 0W-20 if not already running it — cold-weather oil flow protects the VVT-i system on sub-zero starts, which are common in Lake Geneva from December through February.
- Test and load-test the battery before November. The 4Runner's charging system is healthy but the factory battery has a modest reserve capacity; cold cranking amps drop sharply below 10°F.
- Top off washer fluid with a -20°F or colder rated fluid and keep a spare gallon in the cargo area. Salt spray from Highway 12 and Geneva Street will empty a tank fast.
- Inspect wiper blades and consider winter-specific beam blades — the standard blades can ice up and streak in freezing rain, reducing visibility when you need it most.
- Confirm the 4WD engagement (4Hi and 4Lo) works before the first snow — check the indicator lights and listen for clean engagement. Don't wait until you're stuck to find out the transfer case is balky.
- Flush brake fluid if it hasn't been done in the past two years. Moisture-laden fluid performs poorly in the cold and accelerates internal corrosion in the ABS actuator.
Summer
- Check tire pressure after the first warm week — every 10°F rise in ambient temperature adds roughly 1 PSI. The 4Runner's tires are large and carry significant load; under-inflation from winter pressure drops is common.
- Inspect the A/C system performance in May before peak heat — the 4Runner's cabin is large and takes longer to cool. A weak system will be miserable on hot days and may indicate low refrigerant or a failing condenser.
- After a wet spring, inspect the undercarriage for new rust formation and touch up any bare metal before summer heat bakes it in.
- If you're towing a boat on Geneva Lake, flush the rear differential and transfer case sooner than the standard 30k interval — repeated water exposure degrades fluid chemistry faster.
- Check coolant level and condition — summer heat combined with a high-tow workload stresses the cooling system more than everyday driving.
Comparable vehicles
2014 Ford
Explorer
Similar size and 7-passenger option, but unibody construction makes it less off-road capable and typically less durable long-term. Better fuel economy and smoother ride for purely on-road families.
2014 Nissan
Pathfinder
Redesigned to a unibody crossover for 2013; significantly less capable off-road and has a weaker reliability record than the 4Runner, but offers better fuel economy and a more car-like interior.
2014 Jeep
Grand Cherokee
Body-on-frame durability (Trail Rated versions) with strong off-road credentials. Comparable capability but higher long-term repair costs and lower resale value than the 4Runner.
2014 Chevrolet
Tahoe
Full-size body-on-frame alternative with more interior room and towing capacity. More expensive to fuel and own, but a strong choice if you need the extra size and 8,400 lb tow rating.
