2012 Toyota Sienna Tire Information

Beyond the correct tire size, there are a couple of other factors to consider when buying Toyota Sienna tires like where and how you drive, and what tire brand you trust most. When thinking about your driving conditions, consider where you live (mountains vs. city vs. countryside) and the kind of weather can catch you off-guard. (Watch out Tornado Alley!) Drivers in states that fully experience all four seasons often buy two sets of tires: one set for winter, one set for summer. Other drivers buy one set of all-season tires instead. That way they don't have to return to the tire shop and their vehicle is always ready for sun, rain, and light snow!

Next, consider your driving style. If you're an avid off-roader who yearns to pioneer new paths, you have very different tire needs than a highway commuter who doesn't hit the hills very often. Talk to a tire technician at Firestone Complete Auto Care for help choosing the best tire for you, or start shopping for Toyota Sienna tires online.

2012 Toyota Sienna Tire Questions

  • Why does Toyota tire inflation matter? The right tire pressure can make all the difference. Proper tire inflation helps increase fuel economy, improve braking time, and boost tire lifespan! Even a small change in tire pressure can impact your driving.
  • Why are there numbers on the side of my Toyota Sienna tires? Your tire sidewall numbers tell you the recommended load carrying capacity, speed rating, treadwear, traction, and tire size. Talk to a tire technician to learn how to read Toyota tire numbers.
  • How do I check the tread depth on my Toyota tires? Stay on top of your tire tread depth to help avoid a dangerous drive. You can check tread depth with a penny. Hold the penny so that Abraham Lincoln is facing you, then place your penny into a tread groove upside down. If you can see the top of Abe’s head, your tread is shallow and it might be time for new Toyota Sienna tires. Grab a penny. Hold the so that Abe Lincon's head is facing you and his hair is pointing toward the ground. Then, place the penny into a tread groove. If you can see the top of Abe’s head, your tread is shallow and it might be time for new Toyota Sienna tires.

  • Should my Sienna be leaking brake fluid when the car is off?

However, over time, the various components of the brake system can wear out or become damaged, which can cause brake fluid to leak out of the system.

Questions About 2012 Toyota Sienna Engines

  • Are Toyota Sienna engine noises bad? Unusual noises can signal a problem with your Toyota Sienna engine. Tapping or knocking could mean you're low on oil. Whistling could mean a belt is misaligned or there's an intake leak. Squealing can indicate a loose fan belt, and grinding might be coming from the brakes, not the engine.

  • Is temporary sealant bad for my Toyota's tires? A temporary sealant may be able to help you get to a repair location safely. But temporary or emergency sealants could possibly damage TPMS sensors, and in some cases may even void the warranty on your Bridgestone or Firestone tires. If your tire needs extensive repair, sealant can add time and labor costs to the process.
  • What can cause Sienna tires to keep losing air? Your Sienna tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

Stop by for a free battery test at your local Firestone Complete Auto Care to learn more about the state of your battery.
  • How long can I expect my car battery to last? The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.
  • Why is there white, flaky stuff around my Sienna’s battery post?  A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your Sienna car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.

Oil Changes for 2012 Toyota Sienna

Your 2012 Sienna’s oil should be changed according to Toyota’s recommended oil change intervals. Your Sienna may need an oil change right away if your check engine/oil change light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or notice an unusual amount of exhaust.

2012 Toyota Sienna Oil Change Questions

  • What does it mean if my Toyota Sienna oil light comes on?  The oil change light in your Toyota Sienna could be triggered by an overdue oil change. However, if the oil pressure light is on, you may be dealing with low engine oil, a failing oil pump, a clogged oil filter, or a malfunctioning oil pressure sensor.
  • Can I change my Toyota oil on my own?  First off, changing your own oil isn’t as easy as you’d think. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Getting a professional oil change reduces the risk of something going wrong during the service, but also helps your car perform down the road.
  • Why is my Toyota Sienna exhaust smoke grayish or blue?  Your engine could be burning oil due to a leak.  It may be time for a pro to take a look. A leak can be caused by a variety of issues including faulty valve seals, blown piston rings, or damaged cylinder walls.

*Check with a teammate at Firestone Complete Auto Care for complete terms and conditions regarding warranties.

Questions About 2012 Toyota Sienna Engine Tune-Ups

  • What happens if my Toyota Sienna spark plugs fail? When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.
  • What do I do if I see a pool of liquid under my Toyota Sienna? Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.
  • How frequently do the fuel injectors in my Toyota Sienna need to be cleaned? The cleaning schedule for vehicle fuel injectors varies depending on your driving conditions and the type of fuel you use. Some manufacturers suggest cleaning your fuel system as part of routine maintenance, while others will recommend it on an as-needed basis if you’re experiencing poor performance. Reference your Toyota owner’s manual for exact guidelines.

2012 Sienna Toyota Steering & Suspension Services

During the first few years you had your 2012 Toyota Sienna, the ride was probably so smooth that you didn’t even think about it! Lately, though, your ride’s been feeling a little bumpy. Maybe your Sienna jolts, drifts to one side, or makes noise whenever you turn or drive over a speed bump. The first sign of trouble is the best time to bring your 2012 Toyota Sienna in for steering and suspension repairs. We'll get to the root of the problem and, if steering and suspension service is needed, we’ll explain what your car needs and how much it’ll cost to get it done. We won't begin any work without your permission.

Questions About 2012 Toyota Sienna Steering & Suspension

  • Why is my Toyota Sienna bouncing excessively?  If your shocks or struts are in bad shape, they can’t dampen road bumps like they should. This can cause your Sienna to bounce more than usual.
  • Why does my Sienna tilt forward when I hit the brakes?  When you brake, the forward momentum combined with your vehicle's weight sends a lot of force to the vehicle's front end. A bad suspension can cause all that weight and force to push the front end downward.
  • What role do tire pressure and tread depth play in my Toyota's suspension?  Keeping your tires properly inflated can help reduce strain on the suspension, and also help you notice when you need new tires. A tire that doesn't have an adequate amount of tread can't grip the road or function as well as the manufacturer intended.

A/C Service for Your 2012 Toyota Sienna

Our technicians will work to solve your 2012 Toyota Sienna A/C problems to the best of their ability. During this initial A/C performance check, we’ll look at the state of your 2012 Toyota Sienna’s A/C system to evaluate what repairs are necessary (if any). This check includes a visual inspection, performance test, and pressure and leak test.

While your 2012 Toyota Sienna’s air conditioner is being serviced, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Next, they will evacuate the system according to Toyota's recommendations. To finish, we’ll add new refrigerant to recharge the A/C system.

Frequently Asked Questions for 2012 Toyota Sienna A/C Systems

  • What’s making my Sienna A/C put out warm air? Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.
  • What causes A/C system leaks? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your Sienna’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Why won’t my Sienna’s A/C cool the vehicle when the car is stopped?  A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your Sienna is moving. You may be low on refrigerant, or the cooling fan could be faulty.

2012 Toyota Sienna Transmission Service & Repairs

The transmission delivers power from the motor to your wheels so that you can drive at your desired speed. Because your transmission is responsible for converting the right amount of power into the right amount of speed, a small transmission issue can put a big dent in your Sienna’s performance. 2012 Toyota Sienna transmission problems can show up as shifting delays, grinding when accelerating, the car shaking on the road, or whistling noises and a burning smell coming from under the hood. Let Toyota Sienna transmission problems linger and you might notice your fuel economy decrease or find that your Sienna isn’t working at all. Our technicians are trained to service 2012  Toyota Sienna transmission systems according to vehicle manufacturer recommendations. If you think there’s something wrong with your Sienna’s transmission, schedule an appointment at your local Firestone Complete Auto Care to help keep your engine running at peak performance.

2012 Toyota Sienna Transmission Questions & Answers

  • How often does my Sienna transmission fluid need to be checked?  Maintaining your Toyota Sienna transmission fluid is one of the best ways to maintain your transmission's health. A general rule of thumb is to have your transmission fluid checked and changed about every 30,000 to 60,000 miles, but that timeline can change if you're hard on your Toyota. Leaks or low transmission fluid are easy to spot and affordable to repair.
  • Can Toyota Sienna transmission fluid leak? Yes, your Toyota Sienna can develop a transmission fluid leak. As your Sienna ages, parts of the transmission system might wear out or break down, leading to a leak and possible transmission issues. Common causes of transmission fluid leaks include worn seals, a damaged transmission housing, a loose or cracked transmission pan, an overfilled transmission, or faulty transmission lines.
  • Should I avoid driving my Toyota Sienna if there is a transmission fluid leak?  You should avoid driving with a transmission fluid leak. Your transmission system relies on transmission fluid to operate properly, and a leak may decrease performance, cause your Sienna to overheat, or even lead to transmission failure.

Get a 2012 Toyota Sienna Vehicle Inspection

At Firestone Complete Auto Care, we perform a multi-point Courtesy Check during any vehicle service.
