Armed with a smooth and powerful V6 engine, as well as improved braking, this version of the Sienna was our top-rated minivan of its time. Because it was also the only one available with all-wheel drive, we tested both front- and AWD models. Our readers reported the AWD's run-flat tires wore quickly and were expensive to replace. A slightly stiffer ride and a loss of one mpg overall are other sacrifices for AWD.

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.
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.
Fuel Economy & Emissions
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.
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.

"Tire Kingdom I bought new tires and twice car was aligned due to car pulling. Tires rotated to each side and still was pulling to left and right as tires where changed to each side. Took it to my mechanic They said it was a bad tire (5000 miles) on it. Took it to tire kingdom again where I bought them from and they say it is not the tire. Had them check alignment/rotate tires and still same problem Cooper tires (265-70-16) and there vendors cant fix it either"

Anonymous, FL (2008 Toyota Sienna Limited 3.5-L V6)

"The alignment could not be corrected because of a rear axle part which appeared to be damaged.

Anonymous, MA (2008 Toyota Sienna CE 3.5-L V6)

"Driver seat belt won't retract or tighten because of twisting making driving unsafe due to belt caused by insufficient tension in the retraction system . Repair cost (over $300) makes quick replacement prohibitive. Difficult repair job includes taking whole door apart. Talented home mechanics can sometimes fix (or make worse) by carefully untwisting and pushing the belt back through the slot with a screwdriver and needle nose pliers. Other relatively unsafe stop gaps (knotting the seat belt) become necessary, especially if you are in a hurry to get somewhere."

Rodney J., MN (2008 Toyota Sienna XLE 3.5-L V6)

"It started in 2018. Treated air, either warm or cold, is provided to the cabin by vents for the windshield, four in the dash and one on the floor. When the system was "fully operational" the temperature coming out of the dash vents would be the selected temperature. Something has failed and the temperature coming out of the vents varies by location. For instance, in the winter, the right side vents provide cold air! Toyota wanted a lot of money to correct. I generally use either Toyota or a separate "in town mechanic". My mechanic investigated it and advised me that correcting the problem would require removing the dash and replacing several controls at great expense. He advised that I not spend the money since the car is nearly 20 years old. He did a few things to "make it" it tolerable. He was able to keep the windshield defroster working (essential in New England). I totally agreed with his approach since I would like to replace the car in the near term. The Sienna has been a great car and I would like to get another but I have to consider the cost. I may have to settle for a smaller, less expensive new car."

A diagnostic scan said it was an O2 sensor. Over the next several months, I had all the 02 sensors replaced, but the warning light kept coming on & the van continued to behave the same way. 1 mechanic thought it might be spark plugs, but it finally turned out to be the ignition coil - apparently not easy to diagnose.

"The engine, Trac off, & VSC warning lights came on, so I took it to a garage right away. They put a scanner on it & said it showed an 02 sensor. They reset it, but the warnings soon came back. I had the indicated 02 sensor replaced with a new 1, but the lights came back on. I went to a shop that specializes in auto electronics, they did a more detailed scan & found a damaged connection in a sensor & fixed it, but the warning lights came back on soon after. A check with a local mechanic & online seemed to indicate this could be a very difficult problem to pinpoint & fix & that, most times, people have been able to continue driving with these warning lights on & have no big problems. Rather than spend hundreds of dollars more on an old vehicle, with little hope of better results, I've been ignoring the warning lights since January."
