My Altima failed to respond to the start button and exhibited all alarms lit on the dashboard (including erroneous indications of open doors. ) aaa service was forbidden by aaa to provide any service beyond battery and towing. After being towed to a tire shop, I begged the mechanics to detach the ground wire in order to reboot the computer. This worked! an internet search revealed that this condition and fix was identical to ones described in service bulletin ntb12-041. My complaint is against the dealership (Nissan bridgewater NJ) who failed to apply this software patch when it first appeared in April 2012 despite many returns I made to them for routine warranty service. The occurrence of this failure and citation of the service bulletin has been reported by several users in Nissan user forums. This implies that other dealers are similarly negligent in keeping cars current with service bulletins applicable to their vehicle.
The contact owns a 2011 Nissan Altima. After the brake pedal was depressed and the push start was pressed, the brakes seized and there was no engine power. All the warning indicators illuminated when the failure occurred. The vehicle was taken to the dealer where it was diagnosed that a software update was needed. The software was updated, but the failure recurred. The vehicle was brought back to the dealer on two separate occasions when the failure recurred; however, the technicians could not duplicate the issue. The manufacturer was notified. The failure mileage was approximately 35,998.
The car has left me stranded over 20 times this past year from not starting ( I've only had the car a year). All the lights will come on but when I push the start button it won't do anything. It will jump off and might run for weeks but all of a sudden it will fail me again. I have took it to the dealership a couple of times(while it was under warranty) and they said they couldn't find anything wrong with it. I have also took it to autozone several times (after warranty expired) to find out there wasn't a battery issue. I researched online to find many many many complaints about others doing the same thing with most of them saying its a software problem. I feel this should have been taken care of while the car was still under the factory warranty.
