What owners report

Owners of the 2006 G35 most often write about engine oil consumption, which many describe as appearing within the first several thousand miles and requiring frequent top-offs. Other common themes are a third brake light that works only intermittently, an air bag warning light tied to the passenger seat sensor, and a clutch pedal that sticks, mostly on manual-transmission cars.

  1. Engine

    Excessive engine oil consumption

    • 26 complaints (18%)
    • median 20,000 mi at 2.4 yrs old (24 state mileage)
    • filed 2006–2019

    Owners describe the engine using roughly one to two and a half quarts of oil per 1,000 miles with no visible leaks, and say the low-oil condition brings noise on startup and a low oil light. Several report the dealer running an oil consumption test, and some had engines replaced under warranty, while others say the dealer called the usage normal or pointed to driving habits. Complaints describe this most often on manual-transmission coupes. Reported from as low as a few thousand miles up into the 90,000-mile range, with many reports under 10,000 miles.

    What to check: Check the dipstick level and smell for fuel, and ask whether an oil consumption test was ever performed or an engine replaced. Track oil level over the first few hundred miles of ownership.

    2 excerpts from owner complaints in NHTSA records

    “Excessive oil consumption noted at 6,000 miles. Continued with 1,000 mile interval test for oil consumption and found 1qt low at 7,000 miles, 1.5 qts low at 8,000 miles, and 1 qt at 9000 miles. Infiniti said they ordered me a new engine. This was a 2.5 months ago and I'm at 12,500 miles. I've had to top off my engine with a 2 quarts of oil and my own service department does not call me back.”

    NHTSA complaint #10209902, filed 2007-11, 6,000 miles

    “Engine new used 1 qt of oil every 1200 miles. Oil consumption somewhat better with more miles, but still 1 qt/2500 mile presently with 21,000 miles on engine. Dealer said it was my driving habits and nissan/Infiniti won't do anything about it unless it consumes more than 1qt/1000 mile. I followed factory engine break-in guidelines, I do not race my vehicle and dealer has done all factory scheduled oil services. …”

  2. Exterior lighting

    Third brake light works intermittently

    • 19 complaints (13%)
    • median 70,128 mi at 6.0 yrs old (14 state mileage)
    • filed 2006–2017

    Owners report the center high-mount stop lamp on coupes and sedans lighting only some of the time before failing entirely. Most describe noticing it after a few years of use and finding it already out when a passerby or another driver pointed it out. Some say the dealer replaced the assembly, and others report no recall covering it. Typically reported between roughly 45,000 and 110,000 miles, often after four or more years in service.

    What to check: Have someone watch the rear of the car while you press the brake pedal, and check whether the high-mount lamp illuminates consistently.

    2 excerpts from owner complaints in NHTSA records

    “The high mount third stop light works intermittently on my 2006 Infiniti G35 sedan. This is my wife's car and I am concern for the safety of her and others on the road, as this is a safety light that should not fail. After this has been brought to my attention I have noticed that other Infiniti cars on the road have the same problem. This is clearly a safety problem that should not be overlooked.”

    NHTSA complaint #10510607, filed 2013-05, 107,756 miles

    “Third brake light failed on my 2006 G35 sedan. I looked online and found that this is a very common issue, and was pointed to this site to try and get some action done to cover this problem.”

    NHTSA complaint #10379908, filed 2011-02, 45,000 miles
  3. Air bags

    Air bag warning light and passenger seat sensor

    • 20 complaints (14%)
    • median 70,000 mi at 7.7 yrs old (11 state mileage)
    • 5 mention a crash, fire or injury
    • filed 2006–2021

    Complaints describe the passenger air bag light blinking or staying on, sometimes at very low mileage and sometimes after the front passenger seat sensor was diagnosed as needing replacement. Some owners say the dealer could not identify a cause or told them the blinking was normal, and one owner reports being unable to get the seat-related recall performed locally. Reported from about 5,000 miles up to well over 100,000 miles, with no clear pattern otherwise.

    Recall 10V1750003 related service bulletins

    What to check: Turn the key on and watch the air bag lamp through its self-check; ask whether recall 10V175000 was completed and whether the passenger seat sensor was ever replaced.

    2 excerpts from owner complaints in NHTSA records

    “My car was involved in a accident where the front end crumpled but the airbags did not deploy. My daughter was the driver and she was traveling down a 6 lane highway at 30 miles an hour when a van coming out of a median crossed in front of her. She ended up t boning the van.”

    NHTSA complaint #11044404, filed 2017-11, 159,820 miles

    “My car falls under this recall...yet when I take it to the dealership, or look on line on their site. They will not honor the recall- will not fix my car!! What can I do about it? How can I get my car fixed. Below is 1 of 100 articles about it on the internet: nissan is recalling 134,000 Infiniti G35 vehicles due to a defect in their airbag systems that could cause the safety feature not to deploy in an accident. The recall affects 2005 to 2006 models of the Infiniti G35 sedan and 2005 to 2007 models of the G35 coupe. …”

    NHTSA complaint #10680540, filed 2015-02, 57,927 miles
  4. Transmission and drivetrain

    Clutch pedal sticks or fails to return

    Mentioned in 4 of 60 sampled complaints

    Owners of manual cars report the clutch pedal staying near the floor or changing its engagement point, sometimes after long drives or in heavy traffic. Some had the clutch, slave cylinder or master cylinder replaced, and complaints describe the symptom returning after repair. Reported at mileages from single digits up to about 92,000 miles, often after extended driving or stop-and-go traffic.

    1 related service bulletin

    What to check: On a manual car, drive in traffic long enough to warm it up and check that the pedal returns fully and the engagement point stays consistent. Ask about clutch hydraulic service history.

    2 excerpts from owner complaints in NHTSA records

    “I have a 2006 Infiniti G35 coupe with manual transmission. While driving my vehicle for a long period of time or driving in heavy traffic I notice that when I switch gears my clutch pedal gets stuck to the ground and will not pop back into place unless manually pushing it back up with my foot. This has happened multiple times and several other G35 owners have complained about the same problem with their vehicle”

    NHTSA complaint #10749321, filed 2015-08, 70,000 miles

    “Clutch pedal does not return to proper placement under normal driving. Clutch pedal sticks and changes engagement point. Suspected faulty clutch master cylinder.”

    NHTSA complaint #10424058, filed 2011-09, 25 miles
  5. Body and structure

    Seat track and seat movement

    • 6 complaints (4%)
    • median 58,912 mi at 5.0 yrs old (6 state mileage, few)
    • 3 mention a crash, fire or injury
    • filed 2006–2017

    Complaints describe the driver seat shifting or rocking under braking and, in one case, the seat back reclining on its own while driving. Owners report broken seat tracks and, in another case, a seat heater suspected in an interior fire. Some say the dealer replaced a seat switch, and others report no repair. Reported from about 35,000 miles up to 186,000 miles.

    Recall 10V1750001 related service bulletin

    What to check: Sit in the driver seat and push back against it while holding the brake; check for play or rocking, and confirm the power adjustments hold position.

    2 excerpts from owner complaints in NHTSA records

    “The driver side seat track on my 2006 infinite g35x has broken on 3 occasions and has rendered the car undriveable without expensive repair. There is a technical service bulletin dated on july 2007 as seats bulletin 02080. This TSB should become a recall because it is extremely dangerous and almost caused me to get into an accident. And is very costly to repair for the consumer. This is a wide spread problem for the make and model of this vehicle and infinite needs to do a recall.”

    NHTSA complaint #10550049, filed 2013-10, 39,183 miles

    “Driver seat has a lot of movement/play (loose) everytime brake is applied seast moves foreward causing the driver to move along with it. Seat is bolted tightly possible track malfunction. This problem occurs constantly weather vehicle is stationary or in movement.”

    NHTSA complaint #11056162, filed 2017-12, 98,000 miles

Buying note. Have a pre-purchase inspection include an oil consumption check and a scan for stored codes, and confirm any open recalls by VIN. On manual cars, verify clutch pedal behavior and seats for movement before committing.

Example complaints

Engine cooling: “My 2006 Infiniti G35 consumes oil that nissan is aware about. The car doesn't burn oil or leak oil, but consumes around 1 quart of oil every 1800 miles. The manufacture recommends an oil change every 3,750 miles. I change my oil at 3000 miles and everytime I change my oil my car is always 3 quarts low. My car starts to make noises at start up and my low oil light comes on”

NHTSA complaint #10322693, filed 2010-03, 30,000 miles

Air bags: “I was almost a complete stop when I was rear ended. The impact was pretty hard, and the vehicle was ultimately a total loss. At the time of collision, my drivers side seat collapsed back on me almost to a full recline position. Due to this, my seat belt was completely loose, and felt as if I did not have one on. I slid down, and my ankles were bruised on top, and my baseball cap flew off into the back seat. Also, the airbag did not deploy.”

NHTSA complaint #10521365, filed 2013-06, 78,642 miles

Exterior lighting: “I own a 2006 Infiniti G35 and just learned that my center high mount stop light works intermittently. I have begun to research this and discovered that the problem is very common among cars similar to mine. I know the third brake light was working recently and I have seen it illuminate recently but not always. This concerns me for the safety and repair problems, and for the fact that it seems to be a widespread problem with these cars. I think there should be a factory recall issued for this safety equipment.”

NHTSA complaint #10379244, filed 2011-01, 68,256 miles

Electrical system: “While I was traveling on the highway at 70mph, the glass from my sunroof flew off of my vehicle onto on coming traffic. There is no active recall for this and it seems that may other people have had this same issue.”
