We have classified the 2 complaints from 2012 Nissan Versa about SERVICE BRAKES, HYDRAULIC into the following categories.
Tl* the contact owns a 2012 nissan versa. while driving approximately 5 mph, the contact heard an abnormal noise coming from the brake pedal and the accelerator pedal failed. the failure occurred on multiple occasions. the vehicle was driven to the dealer for diagnostic testing. the technician was unable to locate a failure. the manufacturer was not notified of the failure. the approximate failure mileage was 48,000.
The vehicle seems to experience high frequency gas pedal vibration that is felt only between 2500 - 3000 rpm at any speed as long as in this rpm range the vibration can be also felt in the brake pedal without applying the brakes in the same rpm range since there is one bracket for accelerator and brake. no vibration during brake application. the dealer tested the car and stated that another new 2012 versa has the same issue and will not continue to diagnose the problem since it is a waste of time. the problem causes uncomfortable pulsation that results loosing feeling in my foot at that engine speed. i had been an ase certified master technician and i never experience vibration in the gas pedal as an symptom in any of my complaints. after looking at the brake and gas pedal bracket it seems the bracket can flex to any sides with little effort but will stay stable in direction of the pedals travel. the bracket does not seem to be damage just poor design to hold rigidity to side motion. i am not sure if the bracket is causing the problem or other source is transmitting vibration. however, i think there should be no side motion since the assembly can fail due to material fatigue over time. engine and transmission mounts had been checked by myself and the dealer. *tr
The brakes do not brake consistently all the time. on the exact same roads, with the same weather conditions, and at approximately the same speeds; when pushing the brakes with the usual amount of pressure required to stop by a certain distance, the brakes will sometimes not function as usual requiring you to brake hard in order to stop in time. this happened approximately every two weeks or so. driving conditions were dry and threadwear and tire pressure were both fine. would drive 60 miles per day, five days a week.
