Owners have filed 570 complaints
about the 2008 Toyota Sienna with NHTSA between 2007 and 2026.
The largest single group is the body & structure.
Across this model's run it ranks 8 of 23 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 61
Against the median year of the Toyota Sienna. 50 means typical for this
model; 100 means roughly double.
Severity — 67
13% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 39
23% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2008 Toyota Sienna
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

The affected vehicles have a spare tire carrier assembly mounted under the vehicle whose attachment cable may corrode due to high concentrations of road salt splashing onto the spare tire carrier.
Risk: If the carrier cable is corroded due to road salt, the spare tire may separate from the vehicle, increasing the risk of a crash.

POWER TRAIN:AUTOMATIC TRANSMISSION
Toyota is recalling certain model year 2004-2005 Sienna vehicles manufactured January 10, 2003, through August 10, 2005; and model year 2007-2009 Sienna vehicles manufactured February 20, 2007, through December 12, 2008. In the affected vehicles, due to a problem within the shift lock solenoid, there is a possibility that the shift lever could be moved out of Park position without depressing the brake pedal.
Risk: If the shift lever is moved out of the Park position without the brake applied, the transmission will either engage a drive gear or Neutral, increasing the risk of a backover or roll away crash.

Recall 202172355,683 units in Canada
Electrical
Issue: This recall is for certain block heater kits installed on certain vehicles or sold as accessories at Toyota or Lexus dealerships. On certain vehicles, the engine block heater cable may not have enough heat protection and could be damaged by high temperatures. If this happens, the cable could short circuit while plugged in, and cause the wiring to overheat or melt. Note: This recall only affects the following block heater/cord part numbers: C014003034 PK5A408J09 PU14000904 C014003151 PK5A408J13 PU14000905 C014000885 PK5A489J11 PU14000907 C014000888 PK5A489J22 PU14000909 C014000907 PK5A410H00 PU14000911 C014100904 PU14000900 PU14000913 C014100907 PU14000901 PU14003571 C014100911 PU14000902 PK5A489J14 PK5A408J05 PU14000903 Safety Risk: Engine block heater wiring that overheats or melts could create the risk of a fire. Corrective Actions: Toyota recommends that you should stop using the engine block heater immediately. Toyota will notify owners by mail and instruct you to take your vehicle to a dealer to disable the engine block heater. For some vehicles, the corrective actions for this recall are under development. For others, a new engine block heater cannot be installed, and the owner will receive a refund of the purchase price of the engine block heater.
Recall 201418882,381 units in Canada
Structure
On certain vehicles operated where road salts are frequently used, corrosion of the spare tire carrier assembly cable may cause the separation of the spare tire stowed under the vehicle. The spare tire falling on the road surface creates a safety hazard that may result in a crash causing injury and/or property damage. Correction: As an interim measure, dealers will remove the spare tire and store it in the cargo area of the vehicle. Dealers will replace the spare tire carrier assembly when parts become available. Note: This recall supersedes recall 2010-123. Vehicles that were inspected and/or repaired under the previous recall may still be at risk of spare tire separation and will require re-inspection and/or repair.
Recall 201332956,216 units in Canada
Powertrain
On certain vehicles, the transmission may be shifted out of PARK without first depressing the brake pedal. This could result in inadvertent vehicle movement, which could cause a crash resulting in injury and/or property damage. Correction: Dealers will replace the shift lock solenoid.
Recall 2010123138,409 units in Canada
Other
On certain vehicles operated where road salts are frequently used, excessive corrosion of the spare tire carrier assembly cable may cause the separation of the spare tire stowed under the vehicle. Spare tire falling on the road surface creates a safety hazard that may result in a crash causing property damage, personal injury or death. Correction: Dealers will inspect and, as required, either apply a corrosion resistance enhancement treatment to the spare tire carrier restraint cable, repair the cable and apply the corrosion resistance treatment, or replace the spare tire carrier assembly. Note: This recall has been superseded by recall 2014-188.

VISIBILITY/WIPER
The material used by Toyota to manufacture the dash is breaking down. Toyota is aware of this issue due to cracking and offered a limited extended warranty which I never received any notification (and many others did not per Toyota's chat forum). Cracking I can deal with. But now the material is continuing to break down and a thick sticky liquid is separating and rising to the surface creating a terrible sheen. When exposed to direct sunlight the visibility through the front windshield is dangerously low. The road basically disappears. I brought this to the attention of Toyota Brand Engagement Center on Nov. 10. 2023 (File #231110000552). I requested Toyota do the right thing, update their response policy, and authorize a dash replacement at a local Toyota dealership, but they refused based on the response policy they had established many years ago even after I explained the situation is not just cosmetic any longer. I explained the sudden loss of visibility and how incredibly dangerous and frightening it was, but they still refused to address the issue, so I am forced to bring this to your attention. Based on the Toyota's forum this is a widespread issue through several model years. Based on my experience I am confident there will be many accidents due to this manufacturing defect. Please investigate and request Toyota do the right thing to protect their customers.

The contact owns a 2008 Toyota Sienna. The contact stated while pulling into a grocery store, he heard an abnormal ticking sound. The contact stated upon parking and inspecting the outside of the vehicle, he noticed that engine oil was leaking onto the ground. Additionally, the oil dipstick was dry upon inspecting the oil level. There was no warning light illuminated. The vehicle was taken to a local Pep Boys where oil was added in the vehicle and the contact drove to his residence. However, the failure persisted while driving. The vehicle was towed to the dealer where it was diagnosed that the exhaust cam gear had fractured, causing damage to the engine and other unnamed components. The dealer diagnosed that the engine, the exhaust cam gear, and the timing chain needed to be replaced, and additional unknown repairs were also needed. The vehicle was not repaired. The contact related the failure to an unknown Toyota Extended Warranty. The manufacturer was notified of the failure and informed the contact that they could not assist due to the vehicle manufactured date. The failure mileage was approximately 204,000.

The transmission shift cable broke during parking. Although the transmission shift lever was moved to the park position, the transmission was not placed in park. The first observation was the vehicle started to roll when the driver was loading the purchases at a store. The parking brake was then applied. Then the vehicle engine could not be started, regardless of where the shift lever was positioned. The vehicle was towed to an independent auto service provider. The provider identified the problem as the transmission still in the reverse position and replaced a $10 bushing on the transmission cable with a labor charge of $510.
