The 4Runner is among the best off-road-ready SUVs in this price range. Despite retaining a body-on-frame construction, the 4Runner rides better than some car-based SUVs. While its cabin is very roomy and quiet, the 4Runner doesn't provide the nimble, carlike handling of car-based models. Still, it is sound and secure. Side- and curtain-airbags are standard.

Road Test Results

Performance
Acceleration Acceleration Acceleration tests are conducted on a smooth, flat pavement straightaway at the track. Time, speed, and distance measurements are taken with a precise GPS-based device that’s hooked to a data-logging computer.
0 to 60 mph 0 to 60 mph (sec.) The time in seconds that a vehicle takes to reach 60 mph from a standstill with the engine idling.
Transmission Transmission Transmission performance is determined by shifting smoothness, response, shifter action, and clutch actuation for manual transmissions.
Fuel Economy Fuel Economy We perform our own fuel-economy tests, independent of the government's often-quoted EPA figures and the manufacturers' claims. Using a precise fuel-flow measuring device spliced into the fuel line, we run two separate circuits to represent city and highway consumption.
CR's Overall Mileage CR's Overall Mileage CR's overall mileage is a composite of measured fuel usage on a prescribed city course and highway cruising; and CR's 150-mile test trip of mixed driving, if tested. In recent road tests, we've discontinued the 150-mile trip test.
CR's City Mileage CR's City Mileage Measured fuel usage on a prescribed city course.
CR's Highway Mileage CR's Highway Mileage Measured fuel usage on a prescribed highway cruising.
Annual Fuel Cost Annual Fuel Cost The cost and amount of fuel used in 12,000 miles and is calculated from CR's overall mileage.
Braking Braking The braking rating is a composite of wet and dry stopping distances and pedal feel. Braking distance is from 60 mph, with no wheels locked.
Emergency Handling Emergency Handling Several factors go into the rating, including the avoidance maneuver speed and confidence, as well as how the vehicle behaves when pushed to its limit.
Comfort / Convenience
Ride Ride Our expert judgment of how well the suspension isolates and absorbs road imperfections and how steady it keeps the body on various road surfaces.
Noise Noise Our expert judgment of the vehicle's interior noise level in everyday driving.
Front Seat Comfort Front Seat Comfort Our judgment of how comfortable the front seat is for drivers of various heights.
Rear Seat Comfort Rear Seat Comfort Our judgment of how comfortable the rear seat is for two passengers to sit across.
Interior Fit and Finish Interior Fit and Finish An expert evaluation of the interior quality and craftsmanship.
Trunk/Cargo Area Trunk/Cargo Area Our rating is based on the amount of luggage or cargo space that a vehicle has in the trunk or cargo area.
Emissions
Greenhouse Gas Greenhouse Gas The Greenhouse Gas Rating represents the amount of carbon dioxide the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).
NA
Smog Rating Smog Rating The Smog Rating represents the amount of health-damaging and smog-forming airborne pollutants the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).

Owner Reports

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Normal routine brake wear

"I purchased the car used with 80,000 miles and had no history of the previous owner's maintenance or driving habits. When I began to have a bit of vibration when braking around 109,000 miles, I did some diagnostic measurements (runout) and found the right front rotor was not true though still within spec. I decided to simply restore the whole wheel end brake system to restart the history, so to speak. I Installed new rotors and brake pads, and rebuilt all of the calipers. I also flushed and changed the fluid. I used higher performance parts than OEM, and the brakes work great now."

Rust

"The frame was made using substandard steel, Toyota pick up trucks of the same year were recalled for this issue. The 4runner which was built on the same frame was not included in the recall. As a result, advanced rusting on the vehicle's underside is causing premature failure of the brakes, and other parts like muffler shields have had to be replaced.I have been told this rusting will shorten the expected life of the vehicle by 50000 miles. Toyota is aware of this but takes no responsibility."

"The 4runner has over 250,000 miles on it in up state NY, lots of salt.So I would expect rust to become (and it's just becoming)a problem.This year does't have the visor on the back so the salty road spray gets behind the rear window seal and at some point starts the rot. also this year the transmission and power steering lines needed repair because of rust."

I also changed the rear springs and shocks, non OEM, at the same time. The handling has been restored to very acceptable performance, and I now know the history of these parts.

"The Evaporator and condenser went out on my 4 runner in the middle of August last year and these items were behind the dash of my car, so the repair had a TON of labor hours to basically take the whole dash off to get to it.

"Engaging 4WD actuators were not working and could not switch back and forth between 2WD and 4WD. Some of this was due to tires with different tread, and apparently wear and tear from driving on hard roads in 4WD. Took Toyota a week to figure out the problem. Toyata dealer did provide a loaner car for part of that time."
