Each one opens a sheet built from the owner reports of that problem on the 2015 model year.
Is the 2015 Toyota Sienna reliable?
The 2015 Toyota Sienna has 232 owner complaints on file with NHTSA, close to the median of 232 for 2015 minivans on this site. Of the 7 Sienna model years since 2014, it has the most complaints. Complaint counts rise with sales as well as faults, so read what owners report below before deciding.
At a glance
- Next to other model years
- Complaints filed before 2015 aren't in the files this site reads, so the 2015 count runs short and isn't compared with the model years next to it.
- Top problem
- No problem dominates. The largest, sliding door failure, covers 32 of the 232 complaints (14%), and brake wear is next with 18 (one complaint can fall under more than one problem, so these overlap). A quarter of the 18 owners who gave a mileage for sliding door failure saw it by about 19,000 miles, and half by about 30,000.
- Crash, fire and injury reports
- 26 of the 232 complaints (11%) report a crash, a fire or an injury. The typical vehicle on this site sits at 6%, so this one runs well above it. Counted separately (one report can carry more than one), 17 reports mention a crash, 7 mention a fire and 28 people were hurt. The most crash reports, 6 of 17, fall under airbag.
- Recalls behind the top problems
- Sliding door failure, the one problem here with enough reports to check, has a recall on the same system (15V-236, 15V-240 and 16V-858). A recall on the same system doesn't always cover the failure owners describe, so compare its summary with the complaints.
- When owners filed
- Filings jumped in 2017, with 73 complaints, 2.4 times the next busiest year. So far in 2026, 16 more have come in. Filings on record start in 2015.
When each problem shows up
Each bar covers the middle half of the mileages owners reported for that problem. A quarter saw it earlier, a quarter later. The tick is the median. Most reported: sliding door won't open, close or latch, 32 complaints.

How this compares
232 complaints is 1.2 times fewer than the median 2015 model on this site and about the median for a 2015 minivan. Among the 3 Sienna model years here it ranks 1st for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.
