I am reporting a serious and progressively worsening safety issue involving a 2015 Nissan LEAF with approximately 61,759 miles. The problem involves sudden, unintended jerking and apparent repeated braking while driving, accompanied by a forceful steering pull to the left. The exact cause has not yet been determined. Several years ago, the vehicle experienced a serious braking malfunction in which pressing the brake pedal did not stop the vehicle as expected. No warning light appeared during that incident. The...

vehicle was taken to an authorized Nissan dealership, where the 12-volt battery was identified as the problem and replaced. The braking issue appeared to be resolved at that time. Beginning in early 2026, the vehicle began experiencing intermittent jerking while driving. Initially, the episodes were brief and infrequent. Over time, they became more frequent, violent, and unpredictable. The malfunction typically occurs while traveling straight on dry roads at approximately 35-50 mph. Without warning or driver input, the vehicle begins rapidly jerking as though the brakes are repeatedly engaging and releasing. At the same time, the steering wheel pulls forcefully to the left, requiring immediate corrective steering to maintain control. The jerking sometimes continues even after the accelerator pedal is released. During some episodes, the brake pedal pulsates when subsequently applied. On October 30, 2026, the front-right tire blew out during one of these violent jerking episodes. The vehicle was subsequently taken to a tire retailer, where the tire was replaced. The retailer did not identify or report any unusual condition. It is UNKNOWN whether the tire failure was caused by the underlying malfunction or was a separate event. These incidents create a serious risk of losing control of the vehicle, colliding with another vehicle, or leaving the roadway. The unexpected steering movement and apparent braking behavior are particularly dangerous at highway speed
