Engine Burning Oil Problems of Infiniti G35 - part 2

My 2003 Infiniti G35 sedan has an oil consumption issue. Everytime I do an oil change, about 1000 to 1200 miles I check my oil dip stick. It is half way below the full mark. I have repeated done this procedure over 10 times already and have read that this is a common issue with Infiniti and Nissan.

The original engine in my 2005 Infiniti G35 6-speed coupe was replaced due to a high engine oil consumption problem. Infiniti had a service bulletin for this problem and replaced the engine. However the new engine still consumes the same amount of oil and has the same exact problem. The tampa Infiniti dealership is now saying that "it is normal" although the new engine burns a lot of oil like the original engine.

It has been brought to my attention by an Infiniti dealer that my 2006 Infiniti G35 coupe has fallen into a "not good" category for excessive oil consumption.

2006 Infiniti G35 coupe suffering from excessive oil consumption. Car was purchased used from Infiniti of oakland in December 2007 with 15k miles. Car burned 2. 5 quarts between 15k and 20k miles. It is currently undergoing an oil consumption test with Infiniti per service bulletin itb08-002c.

Excessive engine oil consumption: I check my engine oil every 500 miles and I have to add a half quart of oil each time. My engine does not have any leaks, my car has never had any modifications and it is very well maintained.

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.

I have a 2005 G35 coupe w/ heavy oil consumption problems. My car is consuming roughly 3 quarts of oil every 2,000 miles and Infiniti has done an oil consumption test and had one of their techs look at my car and they determined that I needed a new engine but they will not warranty a new one for me. The corporate hq told me they took pictures and a sample,that they have yet to show me and are going to void my warranty. I have since taken it to another shop and they don't agree with Infiniti findings and corporate has still not sent me anything in writing or any pictures of their findings. All I got was a phone call saying they were going to void my warranty and I spoke with the service tech and he does not agree with the findings either and said that my modification to my car does not cause that much oil consumption and I am being shunned away by the dealership. I am also apart of a G35 forum and there are many threads/posts of people with the same oil consumption problem and they are getting the same treatment and I believe that this should be a recall on these engines and I need, along with other need to receive a new engine. Infiniti/Nissan knows about this issue but they will not come clean with their findings and are blaming the customer and I honestly do not think it is fair.

My 2005 Infiniti G35 coupe has been experiencing high amounts of engine oil consumption. Finally, I asked the dealer to perform an engine oil consumption test. Through the course of 3 dealership documented engine oil consumption tests, my car has consumed 4 quarts of engine oil in some 2,739 miles. The Infiniti dealer has advised me that this rate of engine oil consumption is acceptable by Infiniti standards. That I now come to learn that 2005 and 2006 Infiniti G35's and Nissan 350z's equipped with a 6 speed manual transmissions have been plagued with this high rate of engine oil consumption for some time. Should this issue not be a recall item for the consumer?.

I was driving out of town 200km away when all of a sudden my oil light and engine light comes on so I stop at a gas station and buy one quart of oil(full synthetic) then I check my dipstik and I needed more I used almost 3 quarts of oil and on my way back home the same thing happened so I took it to a garage to see if there is any leaks nothing was found and had to pay to have engine light shut off I also went on Infiniti forums and alot of people are having the same problem that I am I contacted Infiniti and they told me that there is nothing they can do other then doing a oil consumption test I said I would do it and if it did burn if they would replace the engine they said no also I know a Nissan/Infiniti garage manager he told me off record that they know there's a problem with the 6 speed (m6) models witch is what I have but they don't know what and won't do anything about it and I called Infiniti head office in canada and tried to talk to them they where very rude and would not talk to me until I send then a copy of my ownership and drivers license and pretty much hung up the phone on me.

Excessive oil consumption and excessive engine noise and/or vibration coming from the engine.

2004 vq35de engine of a G35 couple burns oil rapidly leading to engine failure. Many complaints from other owners have been recorded. Will have to get a new engine soon.

2004 infinity G35 coupe is burning excessive engine oil, I have to add a quart of oil every 1500--2000 miles.

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. I'm tired of this issue and Nissan/Infiniti is not doing anything about it. Its costing me way to much money and I want something done about it.

Excessive oil consumption. One to one and one half quart of oil is used every 700 to 900 miles. Some intervals are shorter at 500 to 700 miles per one quart of oil used and some are longer, 700 to 1,000 one and one half quart will be needed. Oil light has never come on as I have checked the oil every 500 miles since the purchase of this vehicle. Vehicle is currently at 15,800 miles.

Early after I purchased my car G35 6mt 2004 Infiniti coupe I noticed a significant oil consumption occurring between oil changes. I proceeded to file a complaint with the dealer at the next check up appointment but was told there were no issues. I continued to notice the excessive consumption of oil and once more asked the dealer to take a look at it. The second time around the dealer said that there was oil consumption occurring with the car at a rate of over 1/2qt. Per 1,000mi. However, inifiniti refuses to recognize this as excessive, and claims the amount of oil consumed is within normal standards. They claim that a rate of 1qt per 1000 mi. Is still acceptable. This would mean that if I follow the service manual's 3,750mi oil changes I would be left with under 1. 75qts of oil in the engine and in very high provability of explosion. These standards in my opinion seem backward, maybe 40 years ago those standards were correct. I've owned mustangs that have consumed less oil than a brand new luxury vehicle. Up to this point there has been nothing done with regard to this issue, since Infiniti will not recognize their manufacturing defect. There are plenty of other 2004 G35 that do not face this issue. I've continued to invest a considerable amount of money on making early oil changes, which Infiniti will not cover, in fear that if I don't keep the engine in check I may be in danger of an engine explosion or similar.

The contact owns a 2006 Infiniti G35 sedan. The contact heard a ticking sound while accelerating. The dealer was unable to diagnose the cause of failure. The check engine light illuminated at 3,300 miles. The dealer replaced the cam shaft sensor. At 6,400 miles, the ticking noise returned and the check engine and oil lights illuminated. The dealer diagnosed the vehicle as consuming a large amount of oil. The vehicle was put through an oil consumption test and failed twice. At 7,500 miles, the vehicle stalled while turning and the check engine light illuminated once more. The dealer has diagnosed the vehicle as needing a new engine and would like to install a test engine designed for this type of failure. The engine size was unknown. The current mileage is 8,600 and failure mileage was 1,800. The consumer stated the vehicle shifts very rough. Updated 07/06/07.

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. Nissan/Infiniti apparently is aware of this issue and apparently have a revised engine for warranty replacement, but my understanding, only if you consume worse than 1qt/1000 miles. My present oil consumption of 1qt/2500miles in my opinion, is unacceptable in today's standards and feel I should be entitled to this new revised engine for warranty replacement as well.

1. Recently got an oil change and there was 1 qt of motor oil left, I got the next oil change after that and there was again just about 1qt of motor oil 2. Engine oil consumption; engine burning 1qt of motor oil +- every 1,000 miles.

In a little over year after purchasing my G35 sedan I also noticed that it began consuming more oil than normal. I also had to add about 1/2 of oil after every 1500 miles of usage. Oil changes were done every 3000 miles, I also advised Infiniti of the problem but also was told that this oil consumption was normal. I advised the Infiniti rep that my isuzu nor my Nissan ever had this problem of consuming so much oil. A little after the vehicle began to smoke at start ups and began burning more oil. I immediately took vehicle back to Infiniti and advised them of the problem. Infiniti new without even having to examine the vehicle what the problem was and would not honor any warranty repairs, stating poor maintenance. I had to repair the vehicle at my cost. Infiniti knows that this is a defect on most of their vehicles but will not honor the engine warranty and make repairs. I will never purchase an Infiniti vehicle ever again. When ever I get a brochure in the mail from Infiniti I do not bother to open the envelope, I just throw it away in the trash. Infiniti has lost a customer for life.
