Power Train problem #1

Over the last 6 to 8 months, the 2006 M45 stalls intermittently. Most of the time (7 out of 10) it would stall when I stopped at a light (or a stop sign). The engine would shut off, all the indicator lights would come on, and I would put it in park and re-start, and it would continue to operate fine. The other three times or so, the car would randomly shut down while driving (both times in the city at 30 mph or so), and the same procedure to restart. Midas muffler (3 different locations) did not detect any error codes in any of the occasions, and since it was happening intermittently, they could not duplicate it. In atleast 3 or 4 of the events, I had another passenger in the car who observed it.

Power Train problem #2

Traveling at about 60 mph on a state route, the car shut down. No power, no dash lights, inability to use turn signals to indicate the intention of changing lanes to the right and onto the side of the road, which nearly caused a collision as the car slowed to crawl. Once pulled onto the side of the road, after many attempts the car started and we drove it home, the symptons suggest the cam positioning sensor is to blame, which seems to have happened to other motorists.

Power Train problem #3

I was driving on a main street going 50 miles when my engine complete shut off without warning. Everything locked up, steering and breaks were hard to manage. I was lucky enough to coast to a side street. There was a recall 11/17/2003 -03v45500 it also says included are vehicles involved in 01v357 I called Infiniti and they said my VIN excluded my car from that recall. It was towed to a repair shop and the diagnostic came back p0304 camshaft position sensor.

Power Train problem #4

When in motion the engine stall without warning.

Power Train problem #5

This vehicle randomly will shut down all mechanical systems simultaneously at any speed which creates an extremely dangerous situation, especially around other traffic, which could result in a crash. The car's "service engine soon" light appears, the car immediately loses engine power, brakes, and steering and many times will not restart immediately which puts the passengers at risk of a crash in any situation. These are the exact same symptoms of a recall issued by Infiniti for the 2003 M45, however, Infiniti insists that this vehicle is not included in the recall. I have already changed the crank position sensors. Camshaft position sensor(s), and in some cases, the variable timing control sensor(s).

Power Train problem #6

The contact owns a 2007 Infiniti M45. The contact stated that while driving at approximately 65 mph, the vehicle stalled without warning. The vehicle was able to restart after numerous attempts. The vehicle was taken to the dealer, who diagnosed that accelerator pedal sensor needed to be replaced. The vehicle was repaired but the failure persisted. The manufacturer was made aware of the failure. The approximate failure mileage was 122,000.

Power Train problem #7

This vehicle randomly will shut down all mechanical systems simultaneously at any speed which creates an extremely dangerous situation, espcially around other traffic, which could result in a crash. The car's "service engine soon" light appears, the car immediately loses engine power, brakes, and steering and many times will not restart immediately which puts the passengers at risk of a crash in any situation. These are the exact same symptoms of a recall issued by Infiniti for the 2003 M45, however, Infiniti insists that this vehicle is not included in the recall. Maybe once someone is killed in a crash Infiniti will reconsider its position on this matter. According to the Infiniti dealer, they do not know the cause of the problem. Their suggestion was to leave the car with them for 2 or 3 days so they could hook up equipment to the car and drive it around (at $130 per hour) hoping that the problem would occur. Both the dealer and Infiniti USA seem unwilling to investigate this problem without costing me hundreds or even thousands of dollars to fund their research in an effort to prevent a crash. Here is the description of the symtoms caused by the recall: 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.

Power Train problem #8

When braking the car pulls either direction hard also weaves side to side when driving at any speed or if u hit a bump the steering wheel yanks hard to the side. Also when stopped with car n drive and foot on brakes the car will surge forward hard like its going togo on its own.

Power Train problem #9

My 2007 Infiniti M45 suddenly lost all electrical power throughout the vehicle resulting in the engine stalling which potentially could have resulted in a crash. The vehicle was immediately towed to passport Infiniti of alexandria for diagnosis and repair. The diagnostic test revealed a failed intelligent power distribution module, ipdm which after in-depth research, has proven to be faulty in multiple Nissan & Infiniti vehicles ranging from years 2004 - 2006. There are current manufacture recalls on several Nissan vehicles to replace faulty ipdm's and it is my belief that the M45 is affected likewise. Currently, the vehicle is completely out of commission and slightly outside of any manufacture warranty coverage as it is a 2007 with approximately 80,000 miles. I have contacted Infiniti consumer affairs in attempt to gain their acknowledgement and acceptance of full responsibility to cover repair cost without any success. I was informed by a case worker that there is no reported evidence of ipdm failure in the 2007 Infiniti M45 and as a consumer I have to absorb all cost to get the vehicle repaired and returned back to full operational status. The preliminary dealer assessment suggests replacing the ipdm at a very expensive $1300. 00 price tag with a 12 month or 12k warranty. According to the dealer service manager, the cost could be more depending on possible other identified electrical issues that my have triggered the ipdm failure.
