Toyota Sienna — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 21,636 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Body & structure5,606 (25.9%)Official recall records for this system: 10, covering model years 1998–2016.
• Air bags (restraint system)1,768 (8.2%)Official recall records for this system: 15, covering model years 2010–2021.
• Doors, latches & locks1,584 (7.3%)
• Tires & wheels1,570 (7.3%)Official recall records for this system: 3, covering model years 2004–2018.
• Electrical system1,420 (6.6%)Official recall records for this system: 7, covering model years 1998–2020.
• Brakes1,182 (5.5%)Official recall records for this system: 12, covering model years 2011–2022.

Other / uncategorized: 1,230 classifications (5.7%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.

These are counts of records held by CarFaultIQ, not a failure rate. More records can simply mean more vehicles were sold or more owners reported. No vehicles-in-service figure exists in this data, so no reliability or risk score can be derived from it.

What the records are about, by source

Each source is kept separate: owner complaints, recalls, manufacturer communications and investigations are different kinds of record and are never added together. All model years.

• Owner complaints (17,070 records, model years 1998–2020) are most frequently classified under: body & structure, air bags (restraint system) and doors, latches & locks.
• Safety recalls (204 records, model years 1998–2020) are most frequently classified under: equipment & accessories, air bags (restraint system) and body & structure.
• Transport Canada recalls (138 records, model years 1998–2025) are most frequently classified under: fuel system, seat belts and brakes.
• Manufacturer communications (6,568 records, model years 1998–2020) are most frequently classified under: equipment & accessories, electrical system and body & structure.

"Most frequently classified under" reports how the records are filed by the source. It is not a finding about causes, and a record can be filed under more than one system. Read the individual records

Mileage reported when the issue occurred

• 11,970reports included a mileage
• 75,056average of those mileages

This is the mileage owners recorded at the time they reported, not an expected failure mileage and not a prediction for any individual vehicle. The lowest and highest figures on record are not shown: they are unverified odometer entries that include zeros and implausibly high readings, so they would not describe a real range. A median is not shown either, because the stored figures are group totals and a median cannot be recovered from them.

Counts are not adjusted for how many vehicles were sold in each year, so a taller year is not necessarily a worse year.
