2008 Infiniti G35 engine problems

Filed Nov 2, 2023 · Acceleration, Engine · CA

Runaway acceleration. Three times now in the last two weeks the RPMs went to maximum redline without my foot on the accelerator pedal. Fortunately all occurred when I was at very slow speed and either in a driveway or a parking lot. Each time I immediately put the transmission to neutral and shut off the engine. For the first occurrence, Restarting the engine all went back to normal. But for the second instance, two weeks later on restart the engine again instantly went to maximum RPM (deep redline). On a second restart, with additional delay before attempting a restart, the problem cleared. I took the car to a mechanic and they said no error diagnostics were recorded. On test drive he said he noticed some brief unexpected surges. He said for liability reasons no way he would work on the car. No warnings, no instrument indications, car does not seem to "know" throttle is at max redline.

The car idles when taking off even after warming it up... While cars are passing me by. It acts like it wants to cut off while in traffic. It was raining on the passenger side. I can't even filled the car up with a full tank of gas. Only had the car for 3 weeks and the service engine soon light come on. Took it back multiple times and still not fixed

In my car, my radiator failed. That then made the transmission fluid and the coolant mix. My fluid in my radiator and transmission are like slime in there. My car doesn't function like it should.

My car has started stalling while driving, while driving! I have gone to the dealer to have issue fixed, once I get it fixed it happens again, and then the dealer says it might be something else. I have a small child and its terrifying knowing that if I'm on the highway my car will stall or anywhere for that matter. It's been happening for weeks, started at very low speeds and as of yesterday the engine shut off, no steering while going at a higher speed, I could have easily been in a wreck, or even killed someone walking. It's unsafe! There are many forums online regarding this issue with infiniti vehicles and they don't care. Lawsuit waiting to happen.

Almost daily stalling at low speeds. When coming to a slowdown, the vehicle will stall with no error codes or lights given except for power completely turning off. This has resulted in numerous near misses since steering is then not powered and at times in the middle of an intersection. Restart is possible by putting the car in neutral and restarting. I worry that this can cause a wreck when stalling in the middle of the intersection with traffic coming. At times, when coming to a slowdown, the car will stutter as if rpms drop very low but does not stall. The stall and near stall happens frequently.

Put the car in park start the engine and its starts up as normal. This car has gone to the dealer, and 2 other shops 800.00 later its still having a stalling issue. I have a 4 year old and this issue scares me.

Car was jerking while driving. I went to the dealer, was told that a radiator leaked to the transmission, and ruined it. Dealer flashed transmission, but later I had "check engine" warning. I went back, dealer told me that this is because of a bad transmission. This is not safe to drive a car in this condition. I still have a power train warranty, but nissan refuses to repair transmission, because, they say, transmission problem was a secondary one, and the primary was a radiator. Nissan twice refused to repair under warranty.
