The fuel gauge is not reading correctly, and I have to rely on knowing my mileage and how much I last filled in my tank. I have to keep the car running longer than necessary to even duplicate the problem, and when I do the gas gauge just suddenly starts dropping. And if for some reason I even let my gas get low enough to have the low fuel lamp come on, it's almost too late and I barely make it to a gas station. I have not had the issue reproduced/confirmed by any independent servicer. I have seen in many G35 forums that this is an issue that has not had a recall yet. All of the other models for Nissan/Infiniti 2005 were recalled for the fuel sensor in 2010, but not the G35/G37 model. If this keeps happening I will eventually be involved in an accident when my gas runs out unexpectedly on the highway.
I think the clutch wasn't connected right because when i drove it the clutch fell off the car and now i cant drive anyware
My 2005 Infiniti G35 unexpectedly shut off while I was driving it today. Thankfully, I was not on the freeway at the time. The service engine soon, vdc off, and slip lights all came on. I tried to restart the car, and only after multiple attempts (about five) did the car start, and I was able to park in a safe place. Something very similar happened with this car in July 2010. After the July 2010 incident, I had to replace a couple of sensors, which cost over $1,000. I did not expect to have to relive the experience of having my car shut off without warning while driving. I believe that the older (2003) version of the Infiniti G35 had a recall for a similar problem. It is unacceptable that Infiniti / Nissan has not found a permanent solution to this problem. I had my car towed to an Infiniti dealership this evening, and I await the diagnostic reading tomorrow. …
I bought this car in October 2016 from a place called skyline auto, in ham lake,mn didn't jab no concerns when I bought it. There was no ch3ck engine light or tapping feom the motor.

Infiniti G35 sedan 6 speed manual transmission - up rev - vq35de oil consumption is beyond safe and operational under normal driving conditions. Initially car engine seized after 3000 miles of driving. Dealership said it was the oil consumption, and the customer needed to add oil. (this incident was not reported by Infiniti of marin). According to inifinit TSB - itb08-002d - this is an apparent problem, and there is a test and solution for this faulty engine. Inifiniti consumer affairs says I am out of warranty period, and this will have to be an out of pocket expense. They also mentioned it is the responsibility of the dealership to notify the customers, and it is out of their control.
I was driving on the highway at 55 miles an hour when unexpectedly, the car starts to make some noise then it completely shuts down the motor, the check engine light comes on, vdc off, and slip lights all came on. I tried to restart the car, and only after multiple attempts (about three) did the car start. There is no warning. The auto repair facility ran a diagnostic and the code they got was the cam sensors needed replacing, which cost me $650. They said they have been replacing a lot of these. It's very prevalent. They informed me that the 2003 model of the Infiniti G35 had arecall for the same problem.
My infinity G35 2005 m/t has a manufacturers defect of oil consumption and is very common to the engine for this model the vq35 it only has 63,000 miles on it and it consumes 1.5 quarts of oil every 1,000 miles. The car starts knocking with no oil in it by 2,000 after an oil change. I change the oil and only 1 quart comes out when it's supposed to have 5quarts! This is also causing my check engine light to turn on with codes that the oxygen sensors and three way catalyst are bad. It squeals when turning it on and knocks while driving.
We received the car April 18, 2020. We were told that nothing was wrong with the car besides the gas gauge on the dash. On April 20,2020, we were on the highway and the car stopped. We turned the car off for a bit and the problem still persisted. The engine will rev but the car wouldn't go forward nor reverse. We let the car rest for about 20 minutes and it started to work. We then took the car to the mechanic the next day and he told us that the transmission wasn't no good and that's there was an exhaust leak.
