Vehicle Highlights

Infiniti reworked its lowest-priced sedan for 2007, giving it more power and new styling, inside and out. The coupe version of the midsize G35 continued in its 2003-2006 form for 2007. Both the G35 sedan and the coupe had rear-wheel drive, but the sedan also was available as the all-wheel-drive G35x. All models used a 3.5-liter V6 and a five-speed automatic transmission, or a six-speed manual gearbox. Sedans had a 306-horsepower V6, up from a top of 298 in the 2006 season. Coupe engines had 298 horsepower with manual shift, 280 with automatic. The G35x came only with an automatic transmission. Its all-wheel-drive system included a Snow Mode that locked in a 50/50 front/rear power split. Sedans came in base, Journey, G35x, and Sport models. Coupes came in a single trim level. All had antilock braking, traction/antiskid control, front side airbags, and curtain side airbags; the coupe's curtain bags covered front seats only. Standard features included leather upholstery and bi-xenon headlights. A limited-slip differential and sport suspension were included with Sport sedans and manual-transmission coupes; those items were optional for automatic-transmission coupes. Sport sedans and coupes with sport suspension offered versions of Infiniti's "active steer" system, designed to improve handling. The sedan's Navigation Package had a navigation system, voice recognition, and a 9.5 gigabyte hard drive for storing music files. Navigation was a stand-alone coupe option. Keyless entry/starting was standard on all but manual-transmission coupes. Rivals to the G35 included the Acura TL, BMW 3-Series, and Cadillac CTS.

Year to Year Changes


2007 Infiniti G: Infiniti revamps its lowest-priced sedan for 2007, giving it more power and new styling inside and out. The coupe version of the G35 continues in its 2003-2006 form for '07. See 2007-2008 Infiniti G report for sedan information.
2008 Infiniti G: Nissan's luxury division launched a new G37 coupe with a 3.7-liter engine, while the G35 sedan continued with little change. Coupes came only with rear-wheel drive, with a manual gearbox or automatic transmission. The coupe's 3.7-liter V6 generated 330 horsepower. Sedans retained the 306-hp 3.5-liter V6. Coupes were offered in base, Journey, and Sport 6MT trim. The latter included a sport suspension and specific wheels with high-performance tires. New G37 coupe options included "Four Wheel Active Steer," with sensors that adjusted steering and moved the rear wheels slightly when turning.

Consumer Guide® Road-Test Evaluation

Value for the Money
These Infinitis lack the brand prestige of rivals from Audi, BMW, Lexus, and Mercedes-Benz. They don't quite match them for quietness or refinement, either. But their performance, space, and available all-wheel drive makes them excellent alternatives. These virtues, teamed with new-car prices that undercut those rivals, earn the G35/G37 Recommended status.

Each vehicle report contains one rating chart for representative model. Consumer Guide® rates in ten key areas: Performance, Fuel Economy, Ride Comfort, Steering and Handling, Interior Noise, Controls and Materials, Driver Room, Passenger Room, Cargo Capacity, and Insurance Costs. These ratings compare the particular vehicle rated to ALL other vehicles, not a vehicle's standing in a particular class. In the ratings table, "1" is the lowest rating and "10" is the highest rating.
Our reliability study for this generation Infiniti G includes details on average repair costs, manufacturer recalls, and everything you need to know to gauge the long-term reliability of this generation Infiniti G .

Trouble Spots

Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer, however, we have our own expert looking at additional vehicle problems.

Cruise control: The intelligent cruise control may not maintain proper speed when descending hills requiring reprogramming the engine control module. (2007)

None: The brake warning, slip indicator and/or traction control lights may illuminate if the brake light switch goes out of adjustment on sedans with intelligent cruise control. (2007)

None: A tapping noise behind the dashboard may be caused by debris in the heater core that must be flushed out. (2007)

Sunroof/moonroof: The sunroof leaks due to failure of the rubber seal, which must be replaced. (2005-08)

This chart details a range of prices in year-by-year listings for vehicles in three condition levels:
Good: a clean low-mileage, solid-running vehicle that needs little or no repair.
Average: a car with normal miles on the odometer, perhaps a few scrapes or dings; engine might need a minor repair or two, but runs acceptably well.
Poor: might have potentially dangerous problems with the engine and/or body, or abnormally high mileage; definitely in need of mechanical attention. Valuations reflect wholesale prices paid by dealers at auction, and retail prices on used-car lots. Each range covers all trim levels and engine types for a vehicle with a typical amount of equipment--usually an automatic transmission, air conditioning, stereo, etc. Fully loaded vehicles may cost more. Average mileage is 12,000 miles per year. Keep in mind that these are guidelines only. Actual selling prices vary- especially from region to region.
Specs for this generation Infiniti G include everything from fuel mileage to seating capacity to options availability.

NHTSA Crash-Test Results

Test 2008 G35 sedan
Front Impact, Driver 5
Front Impact, Passenger 4

The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Sideimpact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.
