How many miles can a Toyota Sienna last? When you’re in the market for a new or second-hand Sienna, that’s, of course, a very reasonable question to ask. After all, you’re probably looking to get the most bang for your buck. In this blog, we’ll look at this question in great detail but first, let’s start with a quick answer:

How Many Miles Can A Toyota Sienna Last?

Our team here at thedriveradviser emphasizes quality rather than quantity. We are putting a great deal of effort into bringing you the technical aspects of your vehicle in small consumable chunks. Today, we will analyze how many miles a Toyota Sienna can last. We conducted in-depth technical research on several different platforms to answer these questions. 

We took a pool of six thousand one hundred and sixty-six Toyota Sienna units and had them subjected to our rigorous testings. To know how many miles they last, we first performed the most obvious test – we looked at their mileage data. We did our calculations, and the result is formulated into the following table. 

Amount Of MilesPercentage Of Cars
Cars With 150.000+11.47%
Cars With 100.000 – 149.00018.86%
Cars With 45.000 – 99.99939.22%
Cars With 0 – 44.99930.45%

In this first test, we are looking at the percentages of Toyota Sienna in each of the mileage intervals mentioned above. The highest mileage, however, was about 290k miles. 

To be considered reliable, a vehicle must show more than 3% crossing the 150K mile mark. If the vehicle fails to cross this percentage, it is deemed unreliable. Here in the case of Toyota Sienna, we have 11.47% of them crossing the 150k mile barrier, which means that these minivans are reliable.

Furthermore, this data allows us to get a clear picture of the market trend. As you can see, there are about 40% of them between the 45k-100k mile mark. A significant percentage at this interval shows plenty of low mileage vehicles available in the market, which you can consider buying. 

But first, we have to see why the owner wants to sell it in the first place. If any common problems compel the owners to sell their Toyota Sienna, we will get to the bottom of it. If everything goes well, you can decide on the one you find the most perfect – among hundreds of low mileage Toyota Siennas that are available. 

We would recommend those who have accumulated the least number of miles – further buying tips are mentioned in the smart buy section.

How Reliable Is A Toyota Sienna Compared To Its Competitors?

Even when you see a vehicle having hundreds of thousands of miles on the gauge cluster, more proof is necessary to know for sure what you are buying is, in fact, the most reliable and long-lasting vehicle. 

After putting the Sienna against its competitors, one thing was certain; not many competitors could beat Toyota’s reliability.   

ModelSample SizeCars With 150.000+ Miles% Percentage Of Cars With 150.000+Highest Mileage
Toyota Sienna616672011.47%290000
Honda Odyssey73222463.35%340000
Chrysler Pacifica6541150.22%270000
Kia Sedona1298141.07%250000

We performed the same test with the competitors that we had performed on the Toyota Sienna. After the results came in, we analyzed the data and compared it to see if there is a better alternative to the Toyota Sienna. The above data has made it clear that Sienna is one the most reliable minivans that money can buy.

The Honda Odyssey ranks second, while the other competitors on the list are not quite there yet. With most of the competitors relatively new to this segment, we do not have enough data to say whether or not they are reliable. We also have some honorable mentions:

  • Ford Flex
  • Dodge Grand Caravan 
  • Nissan Quest
  • Mazda 5

Toyota Sienna came on the top out of all the minivans we analyzed. Now, we will move to the next segment, where we will subject the Sienna to its own badge mates.

How Reliable Is A Toyota Sienna Compared To Other Toyotas?

We took several Toyota models and examined their reliability based on practical data. We took the mileage numbers of these models and compared them with the mileage numbers of the Toyota Sienna. 

ModelSample SizeCars With 150.000+ Miles% Percentage Of Cars With 150.000+Highest Mileage

Toyota Sequoia 173549828.70%370000
Toyota Sienna616672011.47%290000

The comparative data with badge mates turns out in favor of the Toyota Sienna, which makes it one of the most reliable Toyota – falling behind only the Toyota Sequoia in this test.  

How Much Does Maintenance Cost Per Year?

Toyota Sienna can not be considered reliable if it takes a fortune to maintain. In this section, we will go through several model years and see how much they cost on repairs and maintenance. 

The data in this section speaks for itself. The average maintenance cost came out to be $544.5, which is about $100 less than the competitors. The 2013 and 2016 model is the best model year because it poses the least number of problems and requires less maintenance compared to competitors. Read more about this subject in this post: The Absolute Best Years Of The Toyota Sienna.

According to our research, there are no specific ones that you should keep away from, but our recommendation is to prefer the Toyota Sienna that has accumulated fewer miles. The model year is the least of our concerns. If you are worried about the common issues that it might have, you can refer to the section below.

Toyota Sienna Common Problems

NOTE: Before buying a used car, I always like to make sure the car isn’t having any problems that I should be aware of. The easiest way to do this is by buying an OBD2 scanner. These scanners can easily be plugged into any car you’re interested in, and they’ll give you a rundown of potential problems.

Personally, I like this one on Amazon because it has a lot more functions than basic OBD2 scanners. This particular one also runs tests on your emission system and tests if you’re fuel mix is optimal (or if your engine is misfiring), so you have a complete understanding of how the car’s performing.

Electric sliding door

Toyota Sienna is one of the earliest minivans of Toyota. Toyota Sienna is still maintaining its good reviews because of its safe and comfortable interior. However, electric door automation is still a problem in almost every generation of Toyota Sienna. 

The electric sliding door is one of the most determining features of this vehicle. Toyota received many reports against the problem of automation of electric sliding because users have to open them manually. The reason for the door not working could be because the motor which is supposed to control the door is malfunctioning. Other reasons may occur that the cable of the door is somehow damaged or broken completely.

If you consider replacing, the maintenance cost will be quoted by Toyota at around $1500. In some cases, repair cost has also been quoted around $2000.

Cracks on dashboard

Toyota Sienna, in its early models, had the problem of scratches and cracks on the dashboard. Cracks were seen to be like someone had marked the dashboard with some sharp edge material like a knife or blade.

The reason for cracks is considered to be the exposure of the dashboard to ultraviolet light which can cause cracks and can even break the plastic molecules if left in exposure to UV light for a long term.

The only permanent solution to the problem was to replace the dashboard, which Toyota offered without any cost. Although if you do not find your replacement, some fillers also work like a charm to fill up space.

Oxygen sensors failed

The third most detailed Toyota Sienna issue included the oxygen sensor, which got involved quite a while later. Many people didn’t see any issues with the vehicle however were alarmed when the check motor light went off. While a considerable lot of the sensors fizzled after the vehicle went north of 62,000 miles, a few proprietors detailed issues under 26,000 miles. 

Toyota Sienna oxygen sensor replacement can cost you around $350 where parts will be more or less $250 and labor will give a bill around $100.

Massive oil leak

One more announced issue included Toyota Sienna’s oil line. This leak, for the most part, occurred in more seasoned vehicles. The release required prompt consideration because the vehicle would run out of oil and experience total motor disappointment.

In certain vehicles, the oil line burst out of the blue. Numerous drivers likewise announced that the oil leak occurred without a notice light coming on in advance. Assuming the oil leak occurred while driving, analysts saw a few admonition lights go off immediately.

Likewise, this leak made the vehicle lose the majority of its oil. Owners who had this issue remarked on how much oil emerged from this break. Sometimes the leak covers the engine and inside of the vehicle with oil.

Toyota sienna’s oil gasket replacement will cost you around $200, which can vary according to your trim and model year.

Problematic evaporative emission system

A couple of owners referenced issues with the Toyota Sienna’s evaporative discharge framework. A few reviews had the check motor light come on when there was an issue with the framework. This generally happened because a canister should have been supplanted. Most proprietors announced the canister cost around $310 to change.

Different owners had issues because of a free gas cap. A couple just needed to change their gas cap. Replacement of fuel evaporation system will give you a bill of around $675 where parts are priced somewhere between $550 and $650.

Is a Toyota Sienna A Smart Buy?

Yes, Toyota Sienna is a smart buy. The depreciation on the Toyota Sienna is only 44% after five years which is considered good. There are many competitors offering minivans, but no one does a job better than Toyota when it comes to making them reliable. Toyota Sienna is one of the most reliable minivans that you can get. The biggest selling point is the low maintenance cost. 

When we look at the highest mileage numbers, the data comes out in favor of the Sienna yet again. However, the only drawback is the common problem section, which we elaborated on in the previous section of this article. 

If you are looking to buy a Toyota Sienna, make sure to properly inspect the vehicle and see if it has the common problems. If the Sienna in question does show one or more common problems, you can bargain accordingly. It is best to go for the one that does not show any common issues that Sienna has. Because when it is about the production faults, you either have it or you don’t.

Toyota Sienna Maintenance Schedule

To keep your Toyota Sienna healthy for a long duration, make sure to give it proper care. You have to make sure there is no rust formation on the body, which you can encounter by keeping your van clean — The mud carries water with it, which in turn causes rust. 

Apart from the aesthetics, take care of the maintenance schedule as well. On-time maintenance is necessary to have your vehicle in pristine condition. 

Before/On Every 3,000 Miles 

  • Most manufacturers will give higher mileage numbers to keep the maintenance cost low on papers, but you should replace your engine oil at around 3000 miles. The only time when you can delay the oil change is when you have driven your Sienna very lightly. Aside from this, you should change the engine oil and the oil filter at 3000 miles. 

Before/On Every 10,000 Miles

  • This is the generic inspection interval where all the essential components are checked. If there is an issue, the problem-causing component would either be fixed or replaced. The checklist for this interval includes
  • Brakes inspection
  • Fluids inspection
  • Tire rotation
  • Suspension component inspection
  • Lubrication where required
  • Cabin air filter replacement

Before/On Every 20,000 Miles

  • This is where you need to thoroughly inspect the components and see if there is anything out of the ordinary. The checklist includes:
  • Inspect the exhaust system
  • Inspect the PCV system for any leaks
  • Inspect the brake pads and rotors, replace if necessary
  • Inspect the fuel pump and replace it if necessary

Before/On Every 40,000 Miles

  • Replace the transmission fluid
  • Check the ball joints and other suspension components
  • Check the spark plugs
  • Check for any engine codes
  • Check for any misfiring cylinders

Before/On Every 60,000 Miles

  • Replace the coolant, even if it is the 100k mile coolant. The coolant tends to accumulate debris with the passage of time. 
  • Replace the spark plugs if it has not been replaced before. Make sure to check for the authenticity of the spark plugs you are going for; there are plenty of knockoffs circulating the market, which will cause misfiring at high speed.

Other Maintenance Tips

  • Keep your Sienna clean; it will help keep your Sienna maintained. 
  • Do not forget to give your Sienna rust prevention treatment every now and then.
  • Make sure to always buy clean titles because they will give you smaller maintenance bills. 
  • Try to park your Sienna under a shade to protect its paint job. It will prevent those common dashboard cracks. If you can not find a shade, you can put those dashboard covers on your dash, which will help keep it safe.
