How Many Miles Can An Infiniti G35 Last? (Answered)

How many miles can an Infiniti G35 last? When you’re in the market for a new or second-hand G35, 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, an Infiniti G35 lasts between 190.000 – 220.000 miles. A G35 needs to go to the garage for unscheduled repairs about 0.51 times per year, with an 8% chance of severe problems. Furthermore, G35 owners spend an average of $540 per year on repair costs.

Having said that, we’re certainly not done. Below we’ll first explain in more detail how many miles a G35 can last. After that, we’ll also show you how much a G35 costs per year and which production years are the most and least expensive. Furthermore, we also discuss the common problems that the car can have.

How Many Miles Can An Infiniti G35 Last?

So you are in the market looking for an Infiniti G35. It’s important to know whether the car you are looking for is reliable or not. We have thoroughly gone through extensive data from several different databases to give you the numbers that will make a clear picture of the reliability for your next possible ride.

The first thing that we have to make clear is how long it will last, and the best way to tell that is to look at the mileage of these cars. On average, if there are more than 3% of cars of the same badge over 150,000 miles, then it means these cars are reliable. And it turns out that the Infiniti G35 is a reliable choice indeed.

Amount Of MilesPercentage Of Cars
Cars With 150.000+24.70%
Cars With 100.000 – 149.00048.80%
Cars With 45.000 – 99.99923.82%
Cars With 0 – 44.9992.68%

Out of 336 of the Infiniti G35s that we scrutinized, 24.70% were above the 150k mile mark. This data indicates that these cars are reliable. The highest mileage on average turned out to be 250k miles. This is the number after which they would start giving up on you.

So if you are in the market to buy one of these, make sure that you stay away from the super high mileage ones. Our extensive research also revealed that most of the cars listed for sale are at high mileage, which means that they are going strong because if there were some underlying problem, then most people would be selling at meager miles.

Another reason why we had an excellent percentage is that most of them are old, and they have had plenty of time to cross the 150k mile mark, which leads us to another aspect of this percentage that would require us to make further analysis. To ensure whether or not the Infiniti G35 is reliable, we have many more tests on our list.

By benefiting from the doubt, we will further subject the Infiniti G35 to our rigorous tests even though the data came out to be in favor of it. Let’s see how well it performs on our other tests.

How Reliable Is An Infiniti G35 Compared To Its Competitors?

This is the battle that decides who’s at the top and because most of the competitors here are older vehicles, and it appears that the high percentage wasn’t just because it’s old, but it’s due to the reason that they are, in fact reliable, to begin with.

The Infiniti g35 has proven extremely reliable, but because there haven’t been any newer models, most of which are available, they are now at high mileage. Our data shows that there is a handful of them still below the 45k mile mark. These lower-mile ones are packed with the most bang for the buck.

How Reliable Is A Infiniti G35 Compared To Other Infinitis?

This is the data that will not only let us know whether or not the Inifiniti G35 itself is reliable. It also gives us a better understanding of how reliable the Infiniti cars are in general. When we scrutinized the data, we didn’t have to dig deep to understand the relation between the percentages and which one is the most reliable.

ModelSample SizeCars With 150.000+ Miles% Percentage Of Cars With 150.000+Highest Mileage
Infiniti G353319428.40%250000
Infiniti Q504217210.49%160000
Infiniti QX802210311.40%230000
 Infiniti G37881718.05%200000

It is obvious from the data that the Infiniti G35 is the best Infiniti among all the Infinitis, and this data has been hugely in favor of it. The fight among the badge mates is a kind of fight that helps us better understand the Infiniti lineups.

How Much Does Maintenance Cost Per Year?

It’s important to know how much you would be spending on your car annually because even a vehicle with the worst reliability can pass the 150k miles, given that lots and lots of dollars were spent on maintenance and repairs. So, we need to know how much we are expected to spend on the G35 to keep it running.

Model YearAnnual Maintenance Cost
2003$ NA
2004$ NA
2005$ NA
2006$ NA

On average, you would have to spend about $476, which is an okay amount. There are other vehicles in the market that can cost a lot more than this. And because the Infiniti G35 is so much similar to the Nissan 350Z, their parts are interchangeable, and if you can easily put Nissan 350Z parts in it and vice versa.

Infiniti G35 Common Problems

Common problems would be one of the biggest reasons for a vehicle’s demise. The culprit behind these common problems is none other than the manufacturer itself. We have listed the common problems an Infiniti G35 would pose and how much it would cost to repair. Make sure to inspect the vehicle thoroughly and watch out for these common issues.

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.

Engine Stalling

Engine stalling is one of the most common problems in Infiniti G35. The crankshaft angle sensor or the camshaft position sensor can fail to cause the engine to stall, lose power, or cause other drivability problems. This also causes the check engine light to illuminate.

The replacement for the crankshaft angle sensor can cost anywhere between $201 and $215. And the replacement for the camshaft position sensor can cost anywhere between $202 and $216.

Brake Light Switch Failure

The brake light switch fails to operate the brake lights; this is one of the most common and catastrophic failures in Infiniti G35; a recall was issued to address this failure. The replacement of the brake light switch can cost anywhere between $97 and $109.

Rattle And Tapping Noise of Timing Chain

The rattle and tapping noise is most commonly caused in the 2003 and 2007 models of the G35. This rattle and tapping noise is the calm before the storm as it indicates the upcoming failure of the timing chain. The most common cause for this failure is faulty timing chain guide rails and timing chain tensioners that wear out before time.

These parts keep the timing chain tight and positioned properly, and their failure can cause the chain to become loose. It can even cause the timing chain guide pieces to break off and fall into the oil pan. The replacement of the guides and tensioners is costly and can range anywhere between $1847 and $2250.

Hard Shifting/Wrong Gear Selection

Har shifting/wrong gear selection is also one of the most common problems in Infiniti G35. Still, it can easily be taken care of by simply reprogramming the automatic transmission ECU that you can easily do.

Is an Infiniti G35 A Smart Buy?

To answer this question, let’s first analyze all the data and look at the depreciation value.

The Infiniti G35 faces a depreciation value of about 50%, a common occurrence in so many vehicles on the planet. Now, after analyzing all the remaining data, we conclude that the Infiniti G35 is a reliable car, and it can be considered a smart buy.

Make sure that the one you will buy has no electronics issues, no rattles, and should have a clean title. Ideally, go for the ones below 45k miles, but if you want to go a little higher, then you can. But make sure that they are 100% okay. If the G35 has a problem, then ask the seller to lower the price accordingly.

Infiniti G35 Maintenance Schedule

After going through your options, you can have a better feel for the G35 when you have an idea of the things that need maintenance regularly. The dealerships recommend changing the engine oil at 10,000 miles, but it should be changed before 7,000 miles to get the best performance and reliability.

Before/On Every 10,000 Miles

  • Before every 10k miles, you have to change the engine oil, preferably, before 7k miles to have the best possible performance and reliability.
  • Brake inspections
  • Tire pressure check
  • Diagnosis for any check engine lights
  • Oil filter replacement
  • Check for any oil leaks

Before/On Every 20,000 Miles

  • Power steering check
  • Exhaust system check
  • Transmission fluid level check
  • Fuel lines inspection to make sure that there is no leakage

Before/On Every 40,000 Miles

  • Change fuel filter
  • Flush and change hydraulic fluid
  • Service fuel injectors
  • Inspect the valve cover gasket, and replace it if necessary.
  • Inspect the timing chain whether it’s in sync or not.
  • Inspect and replace the transmission fluid

Note: If you regularly add extremely high-quality cans of petroleum in your gas tank, you can save some bucks on servicing internal components as the petroleum would do the cleaning job without needing to open anything.  You can look up the term Sea Foam or something similar to any other brand of your choosing, and by adding that in your tank, the internals of your engine will remain happy.

Before/On Every 60,000 Miles

  • Replace the spark plug if the spark is orange
  • Rotate or replace the brake rotors as per requirement
  • Clean the fuel system. But if you regularly use the sea foam, you can save some bucks.
  • You might consider changing the timing chain at this point, as in most cases, by this time, the timing chain starts jumping, and that is not good, you will also hear a lot of rattles from the engine if the timing chain has lost its synchronization and has worn out.

Other Maintenance Tips

  • Normally, the manufacturers suggest changing the engine oil at around 10k miles but that’s too good to be true, it’s better you change the engine oil on/before 7-7.5k miles to make sure that the engine remains healthy for a longer period of time.
  • Another important thing is to use high-quality cans of petroleum regularly in your fuel tank, it will help keep the internals clean and would save you a lot of dollars on expensive service for the engine internals, like the throttle body, EGR, cylinder heads, etc.
  • To keep your Infiniti G35 protected from rust, you have to make sure that it doest retain mud on it for more than 4 days because mud contains moisture, and where there is moisture & iron – there is rust, and you wouldn’t want that, so keep your G35 clean.
