How Many Miles Can A Hummer Last? (Answered)

How many miles can a Hummer last? When you’re in the market for a new or second-hand Hummer H1, H2 or H3, 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:

On average, a Hummer lasts between 200.000 – 330.000 miles, depending on the Hummer you have. The H1 with the highest recorded mileage is 200.000 miles. The H2 has the highest recorded mileage of 250.000 miles, and the H3 has the highest recorded mileage of 380.000 miles.

Having said that, we’re certainly not done. Below we’ll first explain in more detail how many miles a Hummer can last. After that, we’ll also show you how much a Hummer costs per year and which production years are most and least expensive. Furthermore, we also discuss the common problems that the car can have.

How Many Miles Can A Hummer Last?

The tanks are made to last, and the Hummer is no exception. With its limited production run for the civilians, we have seen them crossing very high mileages even though they give extremely low mpg. In short, they are made to last, and they are reliable indeed.

To give validity to the reliability claim, we have done extensive research and scrutinized several different databases.

From our research, we wanted to see how many of them could pass the 150k mile mark because if a vehicle can show more than 3% crossing the 150k mile mark, it’s considered reliable. So after we had retrieved the data, we found that the Hummer is extremely reliable, not so surprisingly.

Amount Of MilesPercentage Of Cars
Cars With 150.000+24.27%
Cars With 100.000 – 149.00037.85%
Cars With 45.000 – 99.99930.39%
Cars With 0 – 44.9997.49%

The most reliable SUVs show percentages close to 11%, but here we got through the roof, 24.27% crossing 150k miles. This data suggests that they are incredibly reliable, and they can easily go hundreds of thousands of miles before they can even think of giving up on you. Imagine a tank giving up on you. You can’t because tanks won’t do that. 

How Reliable Is A Hummer Compared To Its Competitors?

Now the Hummer is in a league of its own, not many have what it takes to compete with it, but we digress. We have compiled a list of possible candidates that can put up a good fight against the Humvee. For the first production models, viz the H1, finding any other vehicle close to it is just impossible.

Although the later models can have some relatable competitors because their sizes had been reduced with each new model year, we have made a list anyway, and we will see how utterly other vehicles get defeated.

ModelSample SizeCars With 150.000+ Miles% Percentage Of Cars With 150.000+Highest Mileage
Hummer (Overall)104126224.27%380000
Ford F-1507006745966.56%350000
GMC Yukon631172811.53%280000
Ford Expedition464254511.74%290000
Toyota Highlander127779717.60%329000
Chevy Tahoe11515137811.97%340000

The Hummer H1 can only be defeated in the luxury and mpg department, while the later Hummers also had that under control. As expected, the competitors couldn’t beat Hummer in terms of reliability.

How Reliable Are The Hummer Models?

No such competitor has set its tires in the market as something that can compete with a tank. I mean the hummer. But it’s valuable to see how the Hummer performs concerning its own badge mates.

We expanded our research and scrutinized all the data for all the Hummer models and then analyzed the data to know which Hummer is the most reliable.

ModelSample SizeCars With 150.000+ Miles% Percentage Of Cars With 150.000+Highest Mileage
Hummer H18045%200000
Hummer H256711920.98%250000
Hummer H338013736.05%380000
Hummer H3T15213.33%200000

From our research, it wasn’t really that surprising to see the Hummer H3 at the top. The reason why the H3 got a higher percentage is that a lot of people can afford the H3 while the previous models are super expensive. They aren’t used daily anyway, and because of that, the H1 and H2 had lower percentages crossing the 150k mile mark.

How Much Does Maintenance Cost Per Year?

Now these Hummers are not cheap at all. They are super expensive, even if they are at 300k+ miles. And even when you can set aside the budget to buy one of these, you would have to keep in mind the maintenance cost.

Model YearAnnual Maintenance Cost
Hummer H1$662 on average
Model YearAnnual Maintenance Cost
2007 Hummer H2$683
2008 Hummer H2$829
2009 Hummer H2$789
Model YearAnnual Maintenance Cost
2007 Hummer H3$571
2008 Hummer H3$629
2009 Hummer H3$617
Model YearAnnual Maintenance Cost
2009 Hummer H3T$898
2010 Hummer H3T$875

The data is quite weird when it comes to the annual maintenance cost of Hummer. The same year Hummer of the same lineup can have different maintenance costs per year. We have given an average estimate of how you would have to spend on maintenance per year.

From many different sites and forums, the reviews are rather positive, which means that they are reliable and don’t generally cause major problems. Their maintenance cost has come out to be much less than a lot of other vehicles.

Hummer 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.

Gas Cap Issue

This problem is most common in H2 and H3 Hummers. The gas cap often goes loose or gets worn down, causing the check engine light to illuminate. Although this problem is one the most common ones in Hummer, it can easily be resolved with a new gas cap.

The replacement of the Hummer gas cap can cost you anywhere between $89 to $95.

Failed Mode Door Actuator

A failed mode door actuator in a Hummer can cause improper HVAC temperatures and air delivery. Heaters and AC may malfunction due to the actuator causing improper air temperatures and air delivery. To accurately pinpoint the issue, the fault codes should be analyzed. These fault codes are stored in the HVAC control module.

The replacement of the mode door actuator can cost you anywhere between $490 and $505.

Engine Misfire Due to Worn Valve Seat

One of Hummer owners’ most common issues is the engine misfire caused by worn valve seats. This problem causes the check engine light to illuminate. One way to get rid of this issue might be the replacement of the cylinder head.

The cost of cylinder head replacement can range from anywhere between $1112 and $1338. The major portion of this cost is the labor, while the parts might only cost around $250.

Battery Cable Ends Corrosion

Another one of the most common problems with Hummers is the leakage of battery acid on the cable connection of the battery. It results in the corrosion of the battery cable ends. If this happens to you, then it is recommended that you replace your battery, clean the cables thoroughly, and replace them if required.

The average cost of a Hummer battery replacement is around $302.

Common Issues With the Hummer H1

These Humvees have gotten really old, and because of that, the engine wouldn’t feel as strong as it once was, and there would be some problems if proper maintenance weren’t carried out.

To bring it back to its former glory, you might have to replace the engine, and the most popular engine replacement out there has to be the Duramax. You would be able to find a lot of information about this engine swap on the Hummer forums.

Common Issues With The Hummer H2

The older models didn’t have any apparent issues with the transmission. However, the later models from 2007 onwards have reported issues with the transmission. It’s a trade-off, you can either have minimal interior and no transmission issue, or you can have a luxury interior with most likely a transmission fault.

So when you are looking for a Hummer H2 in the used market, thoroughly inspect the whole Hummer to ensure that the one you are getting has been properly maintained and there are no issues with the transmission.

Common Issues With The Hummer H3

There are some minor issues reported against the H3, but they aren’t alarming issues. With proper maintenance, they go a long way, and some more, before they can even think to leave you and go to heaven. H3 has been by far the most reliable Hummer of all time, surprisingly.

Common Issues With The Hummer H3T

There aren’t that many on sale because there aren’t that many on the planet, to begin with, duh. But the ones that are available for sale, those you can get for an excellent price. Make sure to look under the vehicle for any prominent rust or some undercoatings to hide that rust. This is a rare truck that you should definitely put on your list.

There aren’t that many H3Ts out there; only 5,680 of them were made. Due to their scarcity, we don’t have much data on them to analyze their reliability. The Hummers are so expensive, and H3T being the most scarce, so it should have been expensive, but it’s actually the cheapest Hummer in the market.

Is a Hummer A Smart Buy?

We didn’t have that many Hummers, thanks to the extreme environmentalist who burned a great number of Hummers of the beginning, and the GM had to compromise on the size and performance. Even after that effort, it was still discontinued.

For the Hummer fans, GM would be continuing the Hummer, and we will be seeing Hummers roaming the streets under the GM’s watch. And hopefully, GM wouldn’t ruin the reliability of the Hummer “fingers crossed,” as we have seen in many Chevys, Buicks, and GMCs.

So, is it a smart buy? Well, all the Hummers are good, and If you are looking for a classic beast, go for the H1. If you are looking for a classic with a little luxury added, then go for the H2. If you are looking for a unique truck, then you should go for the H3T. And if you want a reliable and reasonably priced Hummer, then go for the Hummer H3.

With Hummer being continued again, you would be able to buy them new with warranty, and if that is something which excites you more, then new it is. Always go for the ones with lower miles on the odometer, and make sure that it has a clean title.

Hummer Maintenance Schedule

Hummers have elementary maintenance procedures; they are not that complicated to work on; if you are mechanically inclined, it wouldn’t be hard to do the regular maintenance on your own. However, there will be some maintenance that would require the help of professionals.

Before/On Every 10,000 Miles

  • Change Engine Oil
  • Replace the oil filter.

But it’s actually better to change these before/on 7500 miles for best performance and long-lasting protection.

Before/On Every 20,000 Miles

  • Replace the passenger compartment air filter
  • Inspect the tires
  • See if there’s any prevailing rust
  • Check for any fluid leaks
  • Tire replacement

Before/On Every 40,000 Miles

  • Replace the air intake filter
  • Replace the transfer case fluid
  • Inspect the evaporative control system
  • Change the automatic transmission fluid
  • Inspect the differentials and check the oil.

Before/On Every 60,000 Miles

  • Inspect the spark plugs
  • Inspect the ignition coils
  • Have an engine diagnosis with a scanner tool and see for any abnormal reading.
  • Inspect the electronics system
  • Inspect the brake pads and rotors
  • Drive belt replacement
  • The manufacturers recommend changing the first coolant at 60k miles and the later ones after every 30k miles. It depends on different factors, you should check the color of the coolant to tell which one is it. If it’s the silicated one, you would have to change it after every 30k miles and if it’s the extended drain coolant, then you can change it after 100k miles.

Before/On Every 100,000 Miles

  • This is where the suspension components start to wear and you might have to replace the worn-out ones
  • Inspect the transmission fluid and replace it if necessary.
  • Service the radiator core
  • Service the AC condenser

Other Maintenance Tips

To prevent your Hummer from rust, make sure there is no area open to moisture/air; in other words, the paint is not chipped because that’s where the rust will happen. And make sure that you keep your Hummer clean and don’t let mud stay on it for more than 4 days, because after 4 days, the reaction between moisture and iron happens that produces rust.

Have your engine oil replaced before/on every 7500 miles to keep the engine healthier for a longer period of time. And add a can of high-quality petroleum in your gas tank to have the internals of your engine thoroughly cleaned; it’s inexpensive and would save you a lot of dollars on servicing the internals later on.
