Car Accelerates On Its Own problems of the 2010 Nissan Versa

The Nissan Versa is at 96000 miles. The first 2 times it happens was on the street, turning from parking lots to street. The car experienced a sudden accelerate, for a short moment (about 2 seconds). Those 2 times was 1 hour apart. The next times the incident happens was on the highway. From the stop light to entering the freeway, which needs acceleration. The car experienced a rapid shake, sudden accelerates. The accelerations happens very closely to each other, only seconds apart, and more noticeble. The tachometer shakes around 2 to 3. The car was driven off the freeway and back to the parking structure. When transfering, the car still experienced the sudden shakes and acceleration. It hasn't been operated since then due to safy concerns.

2010 Nissan Versa. Consumer states unintended acceleration the consumer stated he experienced engine acceleration while his foot was on the brake. The consumer stated he shifted the gear to neutral and the engine ran at an unusually high rpm for about 10 seconds before returning to its normal 1000 rpm. The second time the incident happened, the consumer was attempting to merge with the traffic from a parallel parking spot and while holding the foot brake, he felt the engine straining until he shifted the gear to neutral which allowed the engine to accelerate briefly and then it returned to normal. Finally, two weeks ago, when the consumer shifted from park to drive, the engine revved up and when he shifted back to neutral the rpm's rose to over 3,000 before settling back to normal.
