The 2008 Infiniti G is a Vehicle History Owner’s Choice award winner for 2008, and with good cause. It’s reliable, fun to drive, luxurious, and cheaper to maintain than a typical luxury car. You can find a sedan in the $8,000 range and the coupe for around $9,000.
Is the 2008 Infiniti G a Good Used Car?
- Overall Rating 8/10 – Just as good as a BMW 3 in more ways than not, but cheaper to maintain.
- Interior, Comfort & Cargo 8/10 – The Infiniti G is one of the most comfortable cars in its class, but the back seat may be an inch too tight, and the coupe’s trunk space is limited.
- Reliability 8/10 – You should be able to make 200,000 miles with no major repairs, but it won’t outlast a Lexus or a Volvo.
- Safety 7/10 – Crash test ratings are kind of mediocre, but standard features are generous, including anti-lock brakes and traction control.
- Gas Mileage 8/10 – The coupe model does 18/24 miles to the gallon, city/highway, which isn’t bad for a 330 horsepower mid-size.
- Value 7/10 – It’s a little pricier than a BMW, but you make up the difference with low repair bills.

What Do Critics Say About the 2008 Infiniti G?
Consumer Reports named the Infinity G the top car in its class, praising the agile handling, sporty performance, and comfortable interior. They note that the car is a bit of a tight fit, lacking rear hip room and trunk space, but they had few other complaints.
Kelley Blue Book report the Infiniti G being a more affordable alternative to the BMW 3 Series Coupe. They found that the car did a fine job of combining luxury, cutting-edge technology, style, and performance all in one package.
Edmunds liked the powerful CV6 engine under the Infiniti G’s hood. They found the cabin roomy enough given the size class, they liked the responsive handling and braking, and they liked the modest price. They note that the clutch pedal feels tricky in a 6-speed manual model.
What Common Problems Does the 2008 Infiniti G Have?
The 2008 Infiniti G has generated just 86 complaints with the National Highway Traffic Safety Administration. Around one third of these are for the airbags, with reports of airbag warning lights flashing on for no apparent reason. A recall was issued in 2008 for occupant classification system glitches.
10 powertrain complaints point to issues with the car stalling in traffic. Drivers report this issue leading to transmission repairs, and usually occurring somewhere between 90,000 to 100,000 miles. Incidence rate is fairly low.
A handful of structure complaints report severe rust in the frame of the car. One driver reports a hole below their passenger door that’s big enough to see through, with their car only having 63,000 miles on the odometer. This issue is easy to prevent with anti-rust spray, but effectively impossible to fix.
The 2008 Infiniti G has only been recalled once, for the above-mentioned airbag occupant sensor issue. Add that to fewer than 100 driver complaints, and you’ve got a car with no major mechanical issues to worry about.
How Long Will the 2008 Infiniti G Last?
Drivers generally report the Infiniti G lasting at least 200,000 miles. Excellent care might get you to 250,000 miles before it becomes too expensive to repair, but maintenance for those first 200,000 miles should be pretty affordable.
Repairpal estimate an annual maintenance cost of $487, which isn’t bad for a luxury sedan. The most expensive common fixes include new power seat control modules, starting at around $991, and new brake master cylinders at $476.
The car is extremely reliable and very high end. I bought it use and it was excellent condition. I would highly recommend this car for anyone. It does sit low to the ground though.
How Is the Technology?
Entertainment technology in the 2008 Infiniti G is impressive for 2008. CD/MP3 players come standard, with an audio input jack, 6 speakers, and XM satellite radio. Audio controls are mounted to the steering wheel, and you’ve got a seven inch color display screen.
Safety technology is good for the model year, too. The car comes standard with anti-lock brakes and electronic brake force distribution.
Is the 2008 Infiniti G a Good Value?
The 2008 Infiniti G is priced fairly, with an entry-level sedan typically listing for around $7,758, and a high-end model going for around $8,183. A coupe typically lists at around $9,014. These prices may be higher than many sedans and coupes in this size class, but they’re around the median for a sporty luxury car.
With the price range being pretty narrow between the entry-level and high-end models, you might assume the Sport edition is a no-brainer. But, you don’t really get that much extra for the money. All the best features are packed into the Base model, leaving the Journey and Sport editions with nowhere to go.

What Colors Does the 2008 Infiniti G Come In?
How Comfortable Is the 2008 Infiniti G?
Both the Coupe and Sedan models stretch about 53 inches across at the hip. The Sedan is, of course, the roomier of the two. Both models feature smooth-riding suspension, high-quality seating, and high-end interior trim materials, so while the G35 may be the more comfortable option, neither are uncomfortable.
How Much Storage Space Does the 2008 Infiniti G Have?
The G35 offers up about 14 cubic feet of storage space, which will pack five or six medium suitcases. The G37 coupe packs just over 7 cubic feet, which is barely enough room for a picnic lunch. If you’re buying a G37, it’s definitely more of a weekend driver than a road tripper.
What Are the Differences Between Years?
The 2008 Infiniti G was the second model year for the sedan, and the first model year for the coupe in the 4th Generation line.
2006: New headlights, bumpers, and spoilers, plus hands-free Bluetooth connectivity, brought the 2006 G model into the modern era.
2007: Sedans were totally redesigned for 2007, with a stiffer body structure, modernized styling, and a retuned chassis for improved handling.
2008: The coupe was added to the 4th Gen lineup in 2008.
2009: Sport brakes were added as an option for sedans in 2009.
2010: The Infiniti G got a new front end for 2010 with a larger grille and darker headlights.
How Does the 2008 Infiniti G Compare to the Competition?
The 2008 BMW 3 Series comes in a wider range of body styles, including wagons, and at a slightly lower price, starting in the mid $6,500 range. It also comes with higher repair bills than the Infiniti G, costing $700 and up in annual maintenance due to the specialty services required.
A Volvo S60 isn’t quite as powerful as an Infiniti G, and it’s sort of boring to look at, but it’s just as luxurious, and it’s one of the safest and most reliable cars in the world. It typically sells in the same price range as the BMW 3, but it can be hard to track one down on the used market.
The Infiniti G is one of the better used luxury cars on the market today. It’s a little pricier than some of its competitors, but it makes up the difference with low repair bills.
