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.

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.

What Owners Say

Alignment

"Because or a problem in the rear axle the car could not be aligned properly until the axle pieces were replaced"

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

"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"

Seat belts

"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."

"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."

Howard M., SK (2008 Toyota Sienna LE 3.5-L V6)

"The engine warning light came on, although the van seemed to continue running normally. A scan indicated an 02 sensor, which I had replaced, but the warning lights came back & continued to show an 02 sensor. I eventually had 3 out of 4 sensors replaced (not cheap). Then another garage discovered the ignition coil need replacing & that seems to have solved the problem."

"Transmission fluid suddenly started leaking, 12 hours later on way to the garage it all 'let go' in the space of 5 mins of driving leaving a trail of fluid from our house to the garage that took months to disappear and in the end leaving the vehicle immobile. Luckily I was just 20 meters from the garage entrance when it finally would no longer move, so some garage workers pushed the Sienna the rest of the way. they said it might have been an overheated radiator that melted a transmission fluid hose the radiator needed replacing too."

The crankshaft bearings rattled for a year then got much worse and I replaced the engine with a Junkyard motor. Toyota claimed that the engine was fixed once and not their problem, although it was never right after the oil total loss. Also they never explained how the engine could lose all its oil and never set off the oil light, even after testing and verifying."

Vidal P., NJ (2008 Toyota Sienna LE 3.5-L V6)

"Our transmission blew out of nowhere on the highway, apparently due to a fitting that was connecting the transmission with the cooling system/radiator. Once that blew, the transmission ended up being a total loss. Luckily, it was covered under a warranty from the used car dealer we purchased it from, but they gave us a used transmission. Then, THAT second transmission also blew! I can't blame Toyota for that, because it was a used transmission, but still (in my opinion) indicative of a major problem with those transmissions. The current (third) transmission has been fine so far, but it has only been a couple weeks. This transmission was sourced from a trusted local mechanic, so hopefully we will have better luck this time."

What Owners Say

Exhaust leaks

"The 3.5L V6 is mounted sideways. The exhaust runs off both sides and meets up under the vehicle just between the front seats. The engine and exhaust needs a little bit to flex so they have springs around exhaust bolts and an exhaust gasket at that junction. After 107k miles on the van, the springs or gasket wore out and created an exhaust leak and rattle at a certain RPM range. The bolts did not break but it was rather loud at times and you could smell the exhaust when it was rattling. Took $100 in parts and less than an hour at a shop so a relatively minor issue."
