2004 Infiniti G35: sudden loss of power

Filed Aug 10, 2016 · Acceleration, Electrical · 108,000 miles · IL

While driving at any speed it will suddenly go into "slip " mode. The service engine, vdc off, and slip warning lights come on, the accelerator stops functioning and the engine coasts. This is extremely dangerous in traffic. There is an active campaign that I have included below on the same vehichles the previous year and some from 2004. When I contacted infiniti multiple times about my vehicle with the same problem they refused to include my car. Summary: on certain passenger vehicles, the circuit board for the crank position sensor or cam position sensor may have an improper solder joint due to solder deformation caused by heat stress accelerated by the existence of flux residue during the soldering process. Consequence: this could cause the "service engine soon" warning light to come on, create a no start condition, cause reduced engine power, or cause the engine to stop running without warning during vehicle operation, which could result in a crash. Remedy: dealers will replace the crank position sensors. Camshaft position sensor(s), and in some cases, the variable timing control sensor(s). Vehicles involved in a previous recall campaign, 01v357, are also included in this new campaign. The replacement sensors used in that campaign are also affected. Owner notification began on december 22, 2003. Owners should contact nissan at 1‑800‑647‑7261 or infiniti at 1‑800‑662‑6200. Notes: nissan recall no. R3022/infiniti recall no. R3021. Customers can also contact the federal safety agency's auto safety hotline at 1-888-dash-2-dot (1‑888‑327‑4236).

2004 infiniti g35 lost power when driving. Service engine soon light as well as vdc lights are on. It is hesitant to start after that. Has happened at least one time each during the last three times the car was driven. Major safety issue as the it has happened when turning at a major intersection. Luckily we were able to coast the car to the side of the road. Same issue exist on the 2003 g35 in which there was a recall for, but none exists for the 2004 models. Contacted infinit in which I was told there was no active campaigns for my model, except for the side airbags. Was told that this would be treated as a repair (subject to very high dealer costs) and not a recall. I have found many other post on the internet with the same issue for the same model and the same complaint that it is not addressed by infiniti. How has infiniti verified that this does not exist in other model, especially being so close the 2003 and 2004?!? This is a major safety issue.

This just started for me, I was driving along in traffic on the highway when all of sudden my car just loss power and wouldn't accelerate. Not yet stalled but going about 2 MPH, I was able to get it to the side of the highway. It ended up stalling out when I stopped, I couldn't get the vehicle started, it was acting like it didn't have gas, but it did. A light saying vdc (slipped) turned on as well as the service engine soon. I experienced the total loss of power while accelerating. Needless to say I took it to the dealership. They charged me stating that it was all fixed but it did the same thing on saturday 9/12/15. 2004 is not a year impacted by the recall yet I'm having the same issue as the 2003 recall.

I have owned my 2004 g35x outright for 9 years now. Bought it brand new in 2005. I have kept up all the maintenance, and have loved my car up until this point. I was driving on a two lane road, and decided to pass the car in front of me. My speed was approx 70 MPH and I had not quite passed them when the car lost all power. The vdc light/slip light/service engine light all came on. Dash lit up like a christmas tree. My steering was non existant, and had complete loss of power. Luckily no one else was on the road!!! And I coasted into a driveway. Waited a few minutes, and the car started up fine. Fast forward to january, and I was driving in rush hour traffic going about 40 MPH when the same thing happened. Luckily, again, I was able to get car to a safe place. The dealer said it was a failure on 2 sensors. Cam and crankshaft, the same sensors that had been recalled on the 2003 models and 2005!!!! Very harrowing, and frightening experience. Also memorable on my purse as the cost to fix was $770, however the dealer was kind to give me a discount and a loaner car, and good service. Shouldnt the 2004 been recalled as well!!!???? Seems there are a lot of other complaints with the same make/model and same defective part. I am glad I was not and that another car were not involved in an accident stemming from this defect. This car will clearly be out on the roads for awhile, as some might give it to their kids for their first car, even though it is 10 years old. I'm clearly concerned about the safety of this vehicle!

I was on the side of a mountain road when suddenly the car started shaking and I lost engine power as well as power steering. All engine lights turned on. I looked this up, and it seems like many people have had this problem so there was recall on the infiniti g35 sedan, but interestingly not on the coupe. The recall is regarding the camshaft positioning sensor. I had my car towed afterwards to my mechanic and he verified the problem was this sensor as well. This car failure was very sudden and extremely dangerous.

Car was being driven at about 65mph when it lost power and the vdc, slip and check engine soon lights all came on the car regain power but at less amount and was hard to start. Was taken to dealer. And was found to need a cam pos sensor. If this loss of power happen when passing on a 2 lane road I may not be writing this . The 2003 models had a recall I think this model needs one to. The cost was over 350.00.

Yesterday, july 9, 2012, while driving under normal conditions on a main city street the engine on my 2004 infiniti g35 just stopped running. Lost power steering and power brakes. Managed to manually steer the car off the road into a parking lot. The vdc off and slip lights and the check engine soon lights came on. I turned off the ignition and just sat there, stunned, for a few minutes. I decided to try to start it up again, and it did start and sounded ok, so I slowly drove it on home. After doing some research online for the next hour, I kind of figured it might be this defective cam position sensor, as the symptoms my car displayed sounded just like what so many others were describing, plus inifiniti and nissan had a recall for this very problem issued on the 2003 g35. I completely agree with others that the 2004 g35 should be under this same recall. This is an extremely dangerous situation to be driving and suddenly, without warning, lose all engine power. I will add that later that evening I had to go somewhere, so I took a chance that it would make it. It quit on me twice in the area around my home within 10 blocks. So, obviously I cannot take this car very far from home without getting this repaired and replaced. I took it to autozone today to have them find out the code for the check engine soon light. It's what I suspected, 0340, which is the passenger side cam position sensor. The very thing on the 2003 inifiniti g35 model recall.

Dealer installed a new air/fuel sensor. Twenty seven miles later the ses light came on and the engine completely lost power in the middle of an intersection. The dealeship had the vehicle towed to their shop. Then informed me that a codep2135 was detected. The vehilce had just been diaognostically tested and repaired. Could have been a serious accident as a large pick-up stopped only about two feet from my stalled vehicle. I turned the key off and the vehicle started and had normal power, but the service engine light was back on.l
