2003 Infiniti G35: sudden loss of power

Filed Oct 10, 2017 · Engine · 161,000 miles · IL

I have replaced the cam position sensor and the crank sensor and my car continues to stall causing the service engine soon light to appear with a loss of power and intermittent stalling. Infiniti has a recall for this problem (service bulletin: the federal safety agency: 03v455000 cam shaft sensor defective) but they say my car is not included. This is a safety issue because the car looses power and stalls intermittently. The problem occurs when the vehicle is in motion usually at highway speed with the cruise control engaged.

While driving, the vehicle turned off on 2 occasions. On several occasions, it lost power, and then recovered, but twice, it literally turned completely off. The "slip", "vdc off", and "service engine soon" lights all appeared. I took it to my local infiniti dealer who said it was subject to a recall for earlier-produced models, and subject to a bulletin which described exactly what had happened. The crank position sensor and bank 1 and 2 of the cam position sensors had to be replaced at a cost of $563.03, and infiniti says that without the federal safety agency telling them to pay for it, they refuse. This car is a 2003, however, it is in mint condition with less than 55,000 original miles on it--always dealer maintained.

I have a 2003 infiniti g35 and this past week while driving on the freeway my car stalled and lost all power and completely shut off while driving, which almost LED to a very bad deadly car accident on the freeway, I was able to then move to the side of freeway, I then was towed to a infiniti shop and was told the problem was the (crank/cam position sensor weld) area located near the engine and that this issue was a recall with this car, I called and spoke with a representative at infiniti corporation and they did not want to help me, and I am looking to seek further assistance. As listed on the following website, when searching the specific model make and year of my vehicle it is listed as a extremely dangerous recall! Recall subject : nissan/crank/cam position sensor weld the federal safety agency campaign number: 03v455000 component(s): engine and engine cooling all products associated with this recall expand details close 14 associated documents expand manufacturer: nissan north america, inc. 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.

After driving for about 5 minutes the car completely shut off. It was basically a moving parked car!!! The steering wheel locked so it was really hard to pull over. Thank god I was on a local street. I didn't force the steering too much b/c that could affect the power steering. Once on the side, the car took really long to start up, I mean about 5 seconds from hearing the crank to actual startup. Usually it?s instantaneous. Now, the service engine soon, vdc off, and slip lights were on. I got my car checked out with a scanner/diagnosis and it returned code ?p0340 camshaft position sensor.? I just find it really hard to believe nissan/infiniti does not cover such a dangerous problem. I can understand that every car has mechanical/electrical issues but for a car to stop working on the road like that is unacceptable. There was a recall on this issue but according to nissan/infiniti my car VIN is not for this campaign so I was rejected. Itb03-072 safety recall campaign 2002 q45, 2003 m45, g35, 2002-2003 i35; voluntary recall campaign engine sensors infiniti has determined that some 2002-2003 model year infiniti vehicles may have a defect which relates to motor vehicle safety. The engine might stop running while being driven if the crank position sensor or cam position sensor fails. This may also result in the ?service engine soon? Light coming on or reduced engine power. If the engine stops running while driving, this could result in a crash without warning.

Vehicle momentarily lost power and dash instrument lights went on (slip, vdc off, service engine soon). The ipdm (intelligent power distribution module) was replaced by the dealer in december 2011 for the same problems. My research revealed that this is a common problem with this model and year. Separately, high mount rear stop light no longer works. Research indicates this is also a common problem.

Engine became inoperable while driving causing a major safety issue. Several warning lights came on simultaneously (check engine light, slip light, vdc light) at the time. Car was able to be restarted with some trouble. Problem repeated itself (stalling, loss of power, starting difficulty) over next couple days, although warning lights never went off. Independent mechanic identified problem as cam position sensor failures & advised there was a the federal safety agency safety recall (the federal safety agency campaign id 03v455000) for the problem with 2003 g35s, but that my VIN was outside the campaign recall vins. He suggested I contacted infiniti. I contacted both dealer and infiniti national customer service who acknowledged there was a cam position sensor problem with 2003 g35s, but because my VIN was not in the campaign they refused to do anything to address the safety issue. I had the dealer replace the cam position sensors at my expense (about $1500). There are a number of similar complaints filed with the federal safety agency about this problem with no apparent resolution with infiniti. The recall campaign 03v455000 needs to be extended to cover all problem vehicles.

The vehicle HVAC/stereo system lost power and quit functioning causing the windshield to fog up. The only way to see was by wiping the inside glass with paper towels. The system malfunctioned over the past months and now is not operational.

First defect: when I would start my car the lights would go out and the radio, heating and cooling buttons. The fan would come onto high and switch to airconditioning. I could not turn it down or turn it off or turn on my defroster when it was 30 degrees in the morning which made my visibility very poor. The only way to get this to stop was to pull the fuses. We check the recall history and found that it was only a courtesy recall and wouldn't be covered even after reading that hundreds of g35 owners were all having the same problem. We had to have the radio electronics removed from the car and sent out to be fixed. I think this issue would be consisted a safety issue when you don't have heat or a defroster. Second defect: the problem started while the car was idling and it would stall. Then 3 days later while driving at 50mph the car tried to stall and it lost all power and then the dash lights came on indicating service needed. The car seem to lack power. Did a recall check and found that all the conditions pointed to the cam shaft position censor failing. We checked the VIN# and of course my car isn't one that is on their recall list for the same problem they have on other g35 models. This could be a serious safety issue causing an accident when you stall and have no control of your vehicle going down the highway. Every issue I have had with my car has been on the companies recall list but not my VIN # for some reason. This issue to need to reviewed and corrected. Third defect: we have had to have the motor replaced twice in the drivers door that operates the electric window. Now the right door window is not working. If it does open it will get stuck and we have trouble getting it to come up. We have to keep it locked to avoid it being opened. *tr

Im currently having trouble with my center console losing power to my AC and radio. The problems range from center console display shortages, AC blasting at full strength and being unable to change the setting, to the radio intermittently putting out sound. This problem has LED to safety issues with the car in that the inability to control the AC results in fogged over windshields leading to poor visibility. I've read online that this problem affects many owners of the same car. It was such a problem that infiniti recalled the '03 g35 sedan for the exact same problems. It is embarrassing that inifiniti does not stand by their product across the board. If they acknowledged that it was a problem in the sedan why are they not responsible for fixing the same problem in the two door model. Would like to know how this problem may be remedied.

Vehicle would randomly stall out at 50 MPH+ and control of power steering would be lost (battery light & vdc light would come on dash), rendering the vehicle a dangerously fast moving lead sled. Power to the vehicle would resume after a few moments. Many trips to the dealership about this potentially deadly problem yielded no explanation or fix for the problem. After conducting my own research on the internet, it was finally determined to be caused by a malfunctioning crank shaft sensor. The sensor would get too hot and shut down, causing the loss of power to the vehicle. After a few seconds of cooling, power would resume. Apparently a tse bulletin was issued for this problem, but it did not include the VIN for my car since it was produced later in the model year. The sensor (a $40 cost part!) was replaced free of charge at the dealership only after putting up a fight. Infiniti/nissan needs to re-evaluate the scope of affected vehicles involved in this potentially deadly issue or be held responsible should someone die when their car stalls out at 65mph.
