 Apparently on 2009 infifniti g37s, there is a programming error/deficiency in the electronic engine control module (ecm) affecting the processing of the mass flow rate sensor that will cause the engine to unexpectedly (and without a dash warning indicator) to lose power. at occurence of the failure, the car will decelerate from highway speed to less than 35 mph within a few seconds. following the failure, the engine rpm will not exceed 2,400 rpm and speeds above 35 mph are impossible (i found that 4th gear is the highest gear selectable). this failure can be dangerous in a number of traffic situations. i have learned from an infiniti service dept. that the failure will temorarily correct itself if the engine is turned off for a period of time, but that the failure could reoccur. the car's ecm was re-programmed by towbin infiniti (las vegas, nv) on august 30 and that supposedly fixes the failure. while at towbin, the service man said that infiniti knows of the problem, but is waiting to see how wide-spread the problem is. owners have not been told of this problem. towbin service said they have seen about 300 cases of the problem. a salt lake city dealer service dept. had also heard of this problem. again, i feel this problem can be dangerous, because: if it were to occur in heavy traffic, it may be difficult to get out of the way of others; if it were to occur when turning in front of oncoming traffic; after it occurs, there is no way to keep up with higher speed traffic - one is left going slow and hoping no one rear ends me; without more information, i have no way of knowing if the problem has really been fixed.

 1. i was driving my 2009 infiniti g37xs on i-95 near philadelphia. i was using cruise control with speed set at near 65mph. i was listening to pandora internet radio on my htc evo 4g android phone using wimax (4g wireless). the htc evo was being charged using a cellet pmotq9c car charger for cell phones. 2. out of blue, all electrical and electronic system went black. all dashboard display(lcd), entertainmen/navigation system and ac and left/right turn signal and lighting all went out. nothing electronic works including turn signal/emergency light. i was quite nervous, but didn't want to stop at middle of interstate freeway and drive straight home and prayed that power train stay working till i got home. thank god, it did. as soon as i stopped the car by pressing the start/stop button after i drove into my garage, i waited a minute or two and tried to start my car by pressing the start/stop button while pressing the break pedal. the car would not start. i thought that my wireless card key had bad battery. so i spent 15min or so to find my 2nd wireless card key and strangely enough i was able to start the car. however, the service engine soon light on dashboard went on. i called the dealer service and wanted to bring the car. but dealer didn't have any loan car available till next tuesday. so i waited and drove carefully with my car and brought it to dealer on the following tuesday. again strangely, just one day earlier, the service engine light disappeared. i trusted dealer had right equipment to diagnose. 3. dealer took a few days looked at it and could only told me some limited diagnostic info about loss of comm and could not pin point the root cause of problem. i expressed my safety concerns on at night driving on i-95 situation when this happens again. the dealer assured me that all tests were done and no problem was found and the car was safe to drive. 4. i don't feel comfortable and feel that maybe nhtsa can better investigate this.

 2009 infiniti g37 has electrical wiring insulation made of soy-based polymer. soy based polymer is apparently biodegradable. the problem is that it is also attractive to rodents, who eat the wiring, creating electrical safety hazards. in addition to the safety hazards, it also creates an economic stressor on consumers and insurers who have to pay for repairs done to these automobiles, which infiniti claims is not covered under any existing warranty.
