The 2016 Toyota Sienna carries 5 open NHTSA recalls — most recently covering hoses, lines/piping, and fittings. Owners report 7 recurring issue clusters, led by “Premature tire wear and failure.” Toyota's owner's manual splits service into Schedule 1 (severe) and Schedule 2 (normal). Most US drivers fall under Schedule 1 because it covers short trips, extreme temperatures, dusty roads, or heavy idling. The intervals below reflect Schedule 1 — the schedule Toyota recommends for typical real-world use.

Critical for safety and preventing major damage
Replace 0W-20 full-synthetic oil and filter every 5,000 miles under Schedule 1, or 10,000 miles under Schedule 2. Toyota covers the first 2 oil changes through ToyotaCare.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Rotate tires every 5,000 miles. Toyota recommends rotation at every oil change to maximize tire life on FWD and AWD models.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect brake pads, rotors, and parking brake every 5,000 miles. Toyota recommends measuring pad thickness at each service.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Replace DOT 3 brake fluid every 30,000 miles or 36 months. Critical for the integrity of the ABS, VSC, and brake assist systems.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Keeps your vehicle running smoothly and efficiently
Replace the engine air filter every 30,000 miles. Earlier under Schedule 1 if driven on unpaved roads.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Toyota labels ATF as 'lifetime fill' on most automatics, but recommends inspection and replacement every 60,000 miles under severe service. Use Toyota WS or Type-IV — no substitutes.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Toyota iridium-tipped spark plugs are rated for 120,000 miles. Earlier replacement reduces fuel economy and can cause misfires on direct-injection engines.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275
DIY
~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
Toyota SLLC (pink): first change at 100,000 miles, then every 50,000 miles. Do not substitute green or orange coolant — it will damage the cooling system seals.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
Extends the life of your vehicle and improves comfort
Replace the cabin air filter every 30,000 miles, sooner in dusty climates. Located behind the glove box on most Toyota and Lexus models.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
Inspect the serpentine belt and tensioner every 60,000 miles. Toyota uses long-life EPDM belts that rarely fail before 100,000 miles.
Estimated cost — typical U.S. ranges
Dealer
~$195–$235
Shop
~$135–$165
DIY
~$20–$50
DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.
Toyota's 2AR-FE, 2GR-FKS, A25A-FKS, and most Toyota engines built since 2010 use a timing chain rated for the life of the engine. No scheduled replacement.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Pro only
Timing chains are normally lifetime. Listen for rattle on cold start — that's the actionable signal. Replacement is major work, quote separately.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number
